Abstract

The strip (2) to be fitted beneath the ridge ties, has a central lengthwise section (20) and two lateral sections (21) which are impermeable to water. It also has beads of adhesive (22) running along its under surface and lower edges. The central section of the strip is permeable to air and has gutter strips (23) running along its upper surface at the point where the central and lateral sections meet. The strip is made from at least one layer of a flexible synthetic material, and the sides of its central section have regularly-spaced aeration holes (24,25), each made from a partially cut-away tongue which is left attached to the strip to act as a valve against water penetration.

Description

La présente invention concerne une bande de protection pour le faîte d'un toit, deux possibilités d'utilisation ainsi que deux méthodes de pose d'une telle bande.The present invention relates to a protective strip for the roof ridge, two possibilities of use and two methods of fitting such a strip.

Dans la construction traditionnelle d'un toit à deux pans, on a généralement deux rangées supérieures de tuiles, une sur chaque pan, partiellement recouvertes sur leurs extrémités supérieures, par une rangée de tuiles faîtières en forme de portion de tube cylindrique. Vu la forme généralement irrégulière des tuiles, des interstices subsistent sur la ligne de contact entre une bordure latérale de la rangée de tuiles faîtières et les tuiles sur lesquelles ces tuiles faîtières s'appuient. Ces interstices peuvent s'avérer utiles pour l'établissement d'un circuit d'aération de la sous-toiture, respectivement pour l'élimination de la vapeur d'eau qui y serait logée. Par contre, en cas de forte pluie, notamment lorsque la pluie est accompagnée d'un fort vent, les gouttes d'eau peuvent venir frapper le toit et particulièrement la rangée supérieure de tuiles selon une direction pouvant approcher de l'horizontale. Dans ce cas, l'eau peut pénétrer par capillarité sous les tuiles faîtières, va les interstices mentionnés et pénétrer ainsi dans la sous-toiture.In the traditional construction of a hipped roof, there are generally two upper rows of tiles, one on each side, partially covered at their upper ends, by a row of ridge tiles in the form of a portion of cylindrical tube. Given the generally irregular shape of the tiles, gaps remain on the contact line between a lateral border of the row of ridge tiles and the tiles on which these ridge tiles are based. These interstices can be useful for establishing a ventilation circuit for the roofing, respectively for eliminating the water vapor which would be housed there. On the other hand, in the event of heavy rain, in particular when the rain is accompanied by a strong wind, the drops of water can come to strike the roof and in particular the upper row of tiles in a direction which can approach the horizontal. In this case, the water can penetrate by capillarity under the ridge tiles, go to the interstices mentioned and thus penetrate into the roofing.

Un premier but de l'invention est donc de proposer une bande de protection, pouvant être disposée sous les tuiles faîtières, et capable de retenir les infiltrations d'eau en provenance des pans du toit.A first object of the invention is therefore to propose a protective strip, which can be placed under the ridge tiles, and capable of retaining water infiltration coming from the sides of the roof.

Un deuxième but de l'invention est de permettre que la bande de protection permette aussi l'aération de la sous-toiture.A second object of the invention is to allow the protective strip also to allow ventilation of the roofing.

Un autre but de l'invention est de proposer une bande de protection facile à réaliser, pouvant être débitée en rouleaux de longueur déterminée afin de pouvoir facilement être mise ën oeuvre.Another object of the invention is to provide a protection strip that is easy to produce, that can be cut into rolls of determined length so that it can easily be used.

Et enfin encore un autre but de l'invention est de proposer des modes de pose adaptés selon certaines particularités.And finally yet another object of the invention is to propose installation methods adapted according to certain particularities.

Afin d'atteindre ces buts, l'invention propose tout d'abord une bande de protection possédant les caractéristiques mentionnées dans les revendications 1 à 10, deux modes particuliers d'utilisation étant décrits dans les revendications 11 et 12, alors que deux méthodes de pose sont précisées dans les revendications 13 et 14.In order to achieve these aims, the invention firstly proposes a protective strip having the characteristics mentioned in claims 1 to 10, two particular modes of use being described in claims 11 and 12, while two methods of installation are specified in claims 13 and 14.

L'invention est expliquée ci-dessous en regard du dessin annexé comportant les figures où:

  • la figure 1 représente une vue en coupe et en perspective d'une portion supérieure d'un toit muni d'une bande de protection posée selon deux méthodes différentes,
  • la figure 2 représente une première forme d'exécution d'une bande de protection,
  • la figure 3 représente une coupe partielle selon la ligne III-III de la figure précédente, et
  • la figure 4 représente deux autres formes d'exécution d'une bande de protection.
The invention is explained below with reference to the appended drawing comprising the figures where:
  • FIG. 1 represents a sectional and perspective view of an upper portion of a roof provided with a protective strip laid according to two different methods,
  • FIG. 2 represents a first embodiment of a protective strip,
  • FIG. 3 represents a partial section along line III-III of the previous figure, and
  • Figure 4 shows two other embodiments of a protective strip.

A la figure 1 on voit une coupe et une perspective d'une portion supérieure d'une toiture 1 constituée d'une rangée de tuiles faîtières 10, ayant une forme générale d'une portion de tube cylindrique, et dont les bordures 11 et 12 s'appuient chacune sur une portion de surface proche de l'extrémité supérieure des tuiles 13, 14 formant la rangée supérieure de tuiles de chacun des pans du toit 1. Les tuiles 13, 14, de même que celles formant les autres rangées de la toiture, peuvent être de n'importe quel type connu et sont posées selon une manière connue sur les lattes à tuiles 15, elles-mêmes disposées sur une charpente conventionnelle pouvant être en bois ou métallique. Cette charpente comprend une poutre faîtière 16 disposée dans la partie concave des tuiles faîtières 10. De par le procédé de fabrication des tuiles 10, 13, 14, de par les matériaux en lesquels elles sont constituées et de par leurs formes, il existe généralement une fente ou des interstices entre les bordures 11 ou 12 et respectivement les tuiles 13 ou 14. Si ces interstices permettent une aération de la sous-toiture par un flux passant de l'intérieur de la toiture vers l'extérieur, ils permettent malheureusement aussi un passage de l'humidité, notamment en cas de pluie, depuis l'extérieur de la toiture vers l'intérieur. La bande de protection 2 selon l'invention vise donc premièrement à empêcher cette pénétration d'humidité et secondairement à permettre l'aération de la sous-toiture.In Figure 1 we see a section and a perspective of an upper portion of a roof 1 consisting of a row of ridge tiles 10, having a general shape of a portion of cylindrical tube, and whose edges 11 and 12 each rest on a surface portion close to the upper end of the tiles 13, 14 forming the upper row of tiles of each of the sections of the roof 1. The tiles 13, 14, as well as those forming the other rows of the roof, can be of any known type and are laid in a known manner on the tile slats 15, themselves arranged on a conventional frame may be of wood or metal. This frame comprises an ridge beam 16 arranged in the concave part of the ridge tiles 10. By the method of manufacturing the tiles 10, 13, 14, by the materials from which they are made and by their shapes, there is generally a slot or gaps between the edges 11 or 12 and respectively tiles 13 or 14. If these interstices allow ventilation of the sub-roof by a flow passing from the inside of the roof to the outside, they unfortunately also allow a passage of moisture, especially in the case of rain, from the outside of the roof to the inside. The protective strip 2 according to the invention therefore aims firstly to prevent this penetration of moisture and secondly to allow ventilation of the roofing.

Une première forme d'exécution d'une bande de protection 2 vue par dessous est visible sur la figure 2. Selon cette forme d'exécution, la bande de protection 2 est constituée d'une bande en un matériau synthétique imperméable à l'eau, ayant une largeur comprise entre 30 et 50 cm pour des toitures courantes, cette largeur pouvant être adaptée selon les besoins. La bande 2 comprend une portion centrale 20, limitée par deux portions latérales 21. Chacune des portions latérales 21 comprend sur sa bordure proche de la bordure de la bande 2, un ruban adhésif 22 disposé sur la face inférieure de la bande 2 et constitué de manière avantageuse d'un ruban autocollant à double face, collé sur chaque bordure de la bande 2, l'autre face dudit ruban restant pour le moment protégée par un ruban de protection selon une manière connue. Sur l'autre face de la bande de protection 2, à la limite entre les portions latérales 21 et la portion centrale 20, on peut trouver deux nervures en saillie 23, elles aussi constituées chacune avantageusement d'un ruban autocollant et destinées à former des gouttières dont l'usage sera expliqué plus loin. Si dans tous les cas les portions latérales restent imperméables à l'eau, des trous d'aération 24 peuvent être régulièrement percés sur les deux côtés latéraux de la portion centrale 20. Ces trous d'aération 20 serviront à l'aération de la sous-toiture comme on le verra plus loin. Ces trous d'aération 24 peuvent être disposés selon une seule rangée, comme on le voit sur la partie supérieure de la figure 2 ou alors sur plus d'une seule rangée, étant alignés ou décalés comme on le voit sur la partie inférieure de la figure. Sur cette même partie de la figure, on voit sur la droite un trou d'aération 25 d'exécution différente, façonné par une découpe partielle de son pourtour, de manière à laisser une languette formant clapet. Comme on le voit sur la figure 3, cette languette est orientée vers la gauche, soit vers la face supérieure de la bande de protection 2, faisant que le trou d'aération 25 ne s'ouvre que lorsque la pression ambiante est supérieure sur la partie inférieure de la bande de protection, respectivement dans la sous-toiture, que celle régnant sur la partie supérieure de la bande de protection, respectivement au-dessus du toit. Une telle disposition permet une aération à sens unique de l'intérieur de la toiture vers l'extérieur.A first embodiment of a protective strip 2 seen from below is visible in FIG. 2. According to this embodiment, the protective strip 2 consists of a strip made of a waterproof synthetic material , having a width between 30 and 50 cm for common roofs, this width can be adapted as required. The strip 2 comprises a central portion 20, bounded by two lateral portions 21. Each of the lateral portions 21 comprises on its edge close to the edge of the strip 2, an adhesive tape 22 disposed on the underside of the strip 2 and consisting of advantageously of a double-sided adhesive tape, glued to each edge of the strip 2, the other side of said tape remaining for the moment protected by a protective tape in a known manner. On the other face of the protective strip 2, at the limit between the lateral portions 21 and the central portion 20, there are two projecting ribs 23, each also advantageously made up of an adhesive tape and intended to form gutters whose use will be explained later. If in all cases the lateral portions remain impermeable to water, ventilation holes 24 can be regularly drilled on the two lateral sides of the central portion 20. These ventilation holes 20 will serve for the ventilation of the under -Roof as we will see later. These ventilation holes 24 can be arranged in a single row, as can be seen on the upper part of FIG. 2 or else in more than one row, being aligned or offset as seen on the lower part of the figure. On this same part of the figure, we see on the right a ventilation hole 25 of different execution, shaped by a partial cutting of its periphery, so as to leave a tab forming a valve. As can be seen in FIG. 3, this tab is oriented to the left, that is to the upper face of the protective strip 2, causing the ventilation hole 25 to open only when the ambient pressure is higher on the lower part of the protective strip, respectively in the sub-roof, than that prevailing on the upper part of the protective strip, respectively above the roof. Such an arrangement allows one-way ventilation from the inside of the roof to the outside.

Selon une première forme d'exécution, la bande de protection 2 est obtenue par extrusion de deux feuilles en matériau synthétique, de préférence du polyéthylène ou du polypropylène, extrudées en tandem et entre lesquelles on peut placer un grillage 26, constitué de fils textiles ou synthétiques, servant à donner une certaine rigidité à la bande de protection 2 et à empêcher son déchirement. En variante, il est aussi possible d'extruder ou de contrecoller une feuille de polyéthylène ou de polypropylène sur une bande en matériau non tissé, ce dernier matériau assurant la rigidité et la résistance au déchirement de l'ensemble. Dès cet assemblage réalisé, selon l'une ou l'autre des variantes décrites, les rubans autocollants 22 et 23 peuvent être appliqués et les trous d'aération, selon l'une ou l'autre des formes d'exécution représentées en 24 ou en 25, peuvent être effectués par étampage. La bande de protection 2 est ensuite enroulée en une bobine, pouvant être coupée en longueurs standard, par exemple 10 ou 20 m, ou alors coupée sur mesure selon les dimensions de la toiture.According to a first embodiment, the protective strip 2 is obtained by extrusion of two sheets of synthetic material, preferably polyethylene or polypropylene, extruded in tandem and between which a mesh 26, made of textile threads or between, can be placed. synthetic, used to give a certain rigidity to the protective strip 2 and to prevent it from tearing. As a variant, it is also possible to extrude or laminate a sheet of polyethylene or polypropylene onto a strip of nonwoven material, the latter material ensuring the rigidity and the tear resistance of the assembly. As soon as this assembly has been carried out, according to one or other of the variants described, the adhesive tapes 22 and 23 can be applied and the ventilation holes, according to one or other of the embodiments shown in 24 or at 25, can be made by stamping. The protective strip 2 is then wound into a coil, which can be cut into standard lengths, for example 10 or 20 m, or then cut to measure according to the dimensions of the roof.

En revenant à la figure 1, on peut voir comment la bande de protection 2 est disposée ainsi que son fonctionnement. Sur une toiture 1 en voie de finition, c'est-à-dire sur laquelle les tuiles 13, 14 des pans latéraux sont posées, notamment les tuiles des rangées supérieures, alors que les tuiles faîtières 10 ne sont pas encore posées, on déroule la bande de protection 2, depuis une extrémité du faîte à l'autre, en veillant à ce que l'axe longitudinal central 27 de la bande corresponde assez bien avec la ligne centrale de la face supérieure de la poutre faîtière 16. Lors de cette opération, il s'agit de veiller à disposer la bande de protection 2 dans le bon sens, c'est-à-dire que les rubans autocollants 22 sont du côté des tuiles 13, 14, alors que les gouttières 23 sont sur la face supérieure de la bande 2 lorsqu'elle est posée. Afin de l'empêcher de bouger, on peut clouer ou agrafer la bande de protection 2, le long de l'axe longitudinal 27, sur la face supérieure de la poutre faîtière 16. En veillant à ce que la bande de protection 2 ne soit pas tendue latéralement afin de pouvoir ultérieurement disposer les tuiles faîtières 10 sans que celles-ci ne prennent appui sur la bande de protection, on peut maintenant retirer les rubans de protection des rubans autocollants 22 et coller chacune des bordures de la bande de protection 2 sur les tuiles 13, 14. Il ne reste plus qu'à déposer les tuiles faîtières 10 par dessus la bande de protection 2. On remarque sur la figure 1 deux méthodes de pose différents de la bande de protection 2. Sur la portion de gauche de la figure, la bordure latérale de la bande de protection 2, respectivement le ruban adhésif 22 est situé juste sous ou légèrement en retrait de la bordure 12 des tuiles faîtières 10, alors que sur la portion de droite de la figure, la bordure latérale de la bande de protection 2 dépasse de quelques cm la bordure 11 des tuiles faîtières. Pour une pose selon cette dernière méthode, la bande de protection 2, notamment ses portions latérales 21 seront plus larges que pour l'application de la première méthode de pose. Une protection de faîte d'un toit exécutée selon la première méthode de pose est plus discrète et mieux protégée du rayonnement solaire, alors qu'une protection effectuée selon la deuxième méthode de pose est plus efficace. On veillera à choisir pour ce dernier mode de pose, des matériaux ayant une couleur harmonisée à celle des tuiles pour les portions de la bande de protection dépassant les tuiles faîtières.Returning to Figure 1, we can see how the protective strip 2 is arranged and its operation. On a roof 1 in the process of finishing, that is to say on which the tiles 13, 14 of the side panels are laid, in particular the tiles of the upper rows, while the ridge tiles 10 are not yet laid, the protective strip 2, from one end of the ridge to the other, taking care that the central longitudinal axis 27 of the strip corresponds fairly well with the central line of the upper face of the ridge beam 16. During this operation, it is a matter of ensuring that the protective strip 2 is placed in the correct direction, that is to say that the adhesive tapes 22 are on the side of the tiles 13, 14, while the gutters 23 are on the face top of the strip 2 when it is laid. In order to prevent it from moving, it is possible to nail or staple the protective strip 2, along the longitudinal axis 27, on the upper face of the ridge beam 16. Ensuring that the protective strip 2 is not not stretched laterally so that the ridge tiles 10 can later be placed without them support on the protective strip, we can now remove the protective tapes from the self-adhesive tapes 22 and glue each of the edges of the protective strip 2 to the tiles 13, 14. It only remains to deposit the ridge tiles 10 by above the protective strip 2. Note in FIG. 1 two different methods of fitting the protective strip 2. In the left portion of the figure, the lateral border of the protective strip 2, respectively the adhesive tape 22 is located just below or slightly set back from the edge 12 of the ridge tiles 10, while in the right portion of the figure, the lateral edge of the protective strip 2 exceeds by a few cm the edge 11 of the ridge tiles. For an installation according to this last method, the protective strip 2, in particular its lateral portions 21 will be wider than for the application of the first installation method. Roof ridge protection performed using the first installation method is more discreet and better protected from sunlight, while protection performed using the second installation method is more effective. Care should be taken to choose for this last installation method, materials having a color harmonized with that of the tiles for the portions of the protective strip exceeding the ridge tiles.

Il est maintenant possible de décrire le fonctionnement de la bande de protection 2 tant pour permettre l'aération de la sous-toiture que pour empêcher la pénétration d'humidité. En cas d'humidité sous la sous-toiture, celle-ci peut s'échapper par les trous d'aération 24, 25 disposés sur la portion centrale 20 de la bande 2, et passer directement sous les tuiles faîtières 10 d'où elle pourra ressortir vers l'extérieur par les interstices subsistant entre les bordures 11 ou 12 et les tuiles 14 ou la surface supérieure de la portion 21 de la bande 2. Par contre, en cas de pluie, notamment d'une pluie chassée latéralement par du vent, les gouttelettes ne peuvent s'infiltrer sous les bordures latérales 21 vu que celles-ci sont directement collées sur les tuiles et ne laissent aucun interstice. Une goutte d'eau qui pourrait s'introduire par un interstice entre la bordure 12 et les tuiles 14 dans la cas d'une pose selon la première méthode ou entre la bordure 11 et la face supérieure de la portion 21 dans le cas d'une pose selon la deuxième méthode, sera automatiquement arrêtée par l'une des gouttières 23 et redescendra en direction de la bordure 11 ou 12, sans pouvoir accéder à la portion centrale 20 et aux trous d'aération 24 ou 25.It is now possible to describe the operation of the protective strip 2 both to allow ventilation of the roofing and to prevent the ingress of moisture. In case of humidity under the roofing, it can escape through the ventilation holes 24, 25 arranged on the central portion 20 of the strip 2, and pass directly under the ridge tiles 10 from where it may come out towards the outside through the gaps remaining between the edges 11 or 12 and the tiles 14 or the upper surface of the portion 21 of the strip 2. On the other hand, in the event of rain, in particular rain driven laterally by wind, the droplets cannot infiltrate under the side edges 21 since these are directly glued to the tiles and do not leave any gaps. A drop of water which could be introduced through a gap between the border 12 and the tiles 14 in the case of laying according to the first method or between the border 11 and the upper face of the portion 21 in the case of laying according to the second method will be automatically stopped by one of the gutters 23 and will descend in the direction of the edge 11 or 12, without being able to access the central portion 20 and the ventilation holes 24 or 25.

Dans certains cas de construction, il se peut que d'autres moyens d'aération de la sous-toiture soient prévus que ceux passant par les interstices des tuiles faîtières. Dans ce cas, on pourrait s'abstenir de la nécessité de prévoir une portion de la bande de protection 2 qui soit perméable à l'air; on peut donc avoir alors une bande imperméable sur toute sa surface, empêchant ainsi uniquement la pénétration d'eau de l'extérieur vers l'intérieur de la toiture. Dans ce cas, il serait aussi possible de supprimer les gouttières 23 qui n'ont alors plus aucune utilité.In some cases of construction, it is possible that other means of ventilating the sub-roof are provided than those passing through the interstices of the ridge tiles. In this case, one could refrain from the need to provide a portion of the protective strip 2 which is breathable; we can therefore have a waterproof strip over its entire surface, thus preventing only the penetration of water from the outside to the inside of the roof. In this case, it would also be possible to remove the gutters 23 which then have no further use.

Vu les méthodes de pose envisagées ainsi que le fonctionnement de la bande de protection tel que décrit, il peut être avantageux que les rubans adhésifs 22 ainsi que les gouttières 23 possèdent quelques caractéristiques particulières. Vu que les rubans adhésifs 22 sont destinés à être collés sur des tuiles, généralement en terre cuite, il est nécessaire que leurs propriétés adhésives soient optimum sur ce genre de matériau, ceci pour une longue durée et que ces propriétés adhésives restent constantes en dépit de l'ensoleillement et des intempéries. De plus, vu la forme relativement irrégulière des surfaces supérieures de certains types de tuiles, on choisira de préférence un ruban relativement épais et malléable. Un ruban constitué d'un mastic adhésif est particulièrement bien adapté. En ce qui concerne les gouttières 23, celles-ci doivent être relativement épaisses de manière à bien faire obstacle à une remontée d'eau en travers des portions latérales 21; la forme de la section transversale des gouttières 23 peut être par exemple rectangulaire, ou triangulaire ou de n'importe quelle forme adaptée. Un ruban du même type que celui décrit pour les rubans 22 peut être employé, vu ses qualités hydrophobe. En variante, et particulièrement lorsque la feuille de matériau synthétique faisant office de face supérieure de la bande de protection est obtenue par extrusion, les gouttières peuvent aussi être obtenues, selon la forme désirée, lors de cette opération d'extrusion.In view of the proposed laying methods as well as the operation of the protective strip as described, it may be advantageous for the adhesive tapes 22 and the gutters 23 to have some special characteristics. Since the adhesive tapes 22 are intended to be glued to tiles, generally in terracotta, it is necessary that their adhesive properties are optimum on this kind of material, this for a long time and that these adhesive properties remain constant despite sunshine and bad weather. In addition, given the relatively irregular shape of the upper surfaces of certain types of tiles, it is preferable to choose a relatively thick and malleable tape. A tape made of an adhesive sealant is particularly suitable. As regards the gutters 23, these must be relatively thick so as to effectively obstruct a rise in water across the lateral portions 21; the shape of the cross section of the gutters 23 may for example be rectangular, or triangular or of any suitable shape. A ribbon of the same type as that described for the ribbons 22 can be used, given its hydrophobic qualities. Alternatively, and particularly when the sheet of synthetic material serving as the upper face of the protective strip is obtained by extrusion, the gutters can also be obtained, according to the desired shape, during this extrusion operation.

Selon une deuxième forme d'exécution de la bande de protection 2 visible à la figure 4, celle-ci est constituée non plus d'une bande imperméable que l'on perfore afin de permettre l'aération, comme pour la première forme d'exécution décrite précédemment, mais plutôt d'une bande perméable à l'air sur laquelle on dispose deux bandes latérales imperméables afin d'empêcher le passage de l'eau. Par exemple, la bande 2 peut être réalisée dans un produit non tissé, par exemple en polypropylène, capable de laisser passer l'air humide. Pour confectionner les deux zones latérales imperméables 21, il suffit alors de déposer, de coller ou de co-extruder deux bandes en matériau imperméable, par exemple deux films polyoléfine, la portion centrale 20 restant constituée du produit non tissé. Les bandes imperméables disposées de chaque côté de la portion centrale 20 sont appliquées sur la face supérieure de la bande de protection 2, de manière à éviter une progression de l'eau par capillarité depuis les portions 21 vers la portion centrale 20. Comme précédemment, des rubans adhésifs à double face 22 sont disposés sur la face inférieure et sur les deux bordures du ruban 2, alors que des gouttières 23 sont aménagées sur la face supérieure dudit ruban, à la jonction des portions latérales 21 avec la portion centrale 20.According to a second embodiment of the protective strip 2 visible in FIG. 4, it no longer consists of an impermeable strip which is punctured in order to allow ventilation, as for the first form of execution described above, but rather a breathable strip on which there are two waterproof side strips to prevent the passage of water. For example, the strip 2 can be made of a non-woven product, for example polypropylene, capable of allowing moist air to pass. To make the two waterproof lateral zones 21, it then suffices to deposit, glue or co-extrude two strips of waterproof material, for example two polyolefin films, the central portion 20 remaining consisting of the nonwoven product. The impermeable bands disposed on each side of the central portion 20 are applied to the upper face of the protective band 2, so as to prevent progression of the water by capillarity from the portions 21 towards the central portion 20. As before, double-sided adhesive tapes 22 are arranged on the underside and on the two edges of the tape 2, while gutters 23 are arranged on the upper face of said tape, at the junction of the lateral portions 21 with the central portion 20.

La figure 4 peut aussi représenter une troisième forme d'exécution de la bande de protection 2 qui est constituée alors d'un matériau ayant les capacités de laisser passer l'air humide et de bloquer le passage de l'eau plus généralement un matériau semi-perméable. De tels matériaux sont connus généralement sous la marque déposée GORE-TEX. Dans ce cas, il suffit de disposer d'une bande de ce matériau selon la largeur voulue, sur laquelle on dispose de la même manière que précédemment les rubans adhésifs à double face 22 ainsi que les rubans 23 formant gouttières.FIG. 4 can also represent a third embodiment of the protective strip 2 which then consists of a material having the capacities to let moist air pass and to block the passage of water more generally a semi material -permeable. Such materials are generally known under the registered trademark GORE-TEX. In this case, it suffices to have a strip of this material according to the desired width, on which the double-sided adhesive tapes 22 as well as the tapes 23 forming gutters are arranged in the same manner as above.

Comme pour la première forme d'exécution décrite d'une bande de protection 2, la réalisation d'une bande selon l'une ou l'autre des deux autres formes d'exécution peut facilement être réalisée en continu afin de former des rouleaux de longueur convenable. Des bandes de protection 2 réalisées selon l'une ou l'autre des deux dernières formes d'exécution décrites peuvent être posées selon l'un ou l'autre des modes de pose décrits en regard de la première forme d'exécution d'une bande. Il est à remarquer que pour ces deux dernières formes d'exécution, on a toujours un cumul des deux opérations d'aération et de retenue d'eau.As for the first described embodiment of a protective strip 2, the production of a strip according to one or the other of the two other embodiments can easily be carried out continuously in order to form rolls of suitable length. Protective strips 2 produced according to one or the other of the last two embodiments described can be applied according to one or other of the installation methods described with regard to the first embodiment of a bandaged. It should be noted that for these last two embodiments, there is always a combination of the two aeration and water retention operations.

La bande de protection a été décrite pour être utilisée sur un toit à deux pans se terminant par une arête sommitale, l'homme du métier saura adapter les dimensions ainsi que la répartition des différentes portions de la bande selon la géométrie de n'importe quel type de toiture.The protective strip has been described to be used on a hipped roof ending in a summit ridge, the skilled person will know adapt the dimensions and the distribution of the different portions of the strip according to the geometry of any type of roof.
