Definitions

  • the invention relates to a sub-roof element, comprising a pliable web-shaped material which may form a sub-roof.
  • The. invention was especially developed in connection with the demand for an air slot system and a wind screen on top of the insulation in parallel roof structures (insulated pitched roofs without any cold loft).
  • Such wind screens are used on top of the insulation in order to ensure efficient air passage from cornices to the roof ridge.
  • Present concepts comprise utilization of sheets of cardboard which are placed between the rafters and are tacked to the latter. Insulation is placed from the underside, up towards the wind screen. This may cause strain on the wind screen, to bend or press it up towards the sub-roof and air may, thus, be prevented from passing through efficiently.
  • the wind screens are arranged with transversal laps which must be taped. Poor lap Joints may result in strong air draughts through the insulation, with associated poor thermal economy.
  • spacing clips which are mounted in the joints between wind screens, but such clips provide poor protection against the plate buckling or being pressed upwards between spacer clips which are placed at relatively large intervals.
  • a concept is known for a wind tight, water-proof plate which is open to diffusion and made of a foldable, preferably sheet lined massive cardboard, said plate being divided by the aid of folding indications into a number of parallel panels so that it may be folded with the flat sides of the panels in mutual contact into an elongated, relatively rigid member. Utilizat ⁇ ion of such plates will especially be advantageous as regards transport and mounting, but the same disadvantages as mentioned above will prevail, i.e. the plates will show poor resistance against buckling and pressure in an upward direction when insulation is laid between rafters, and wind suction on the upper side may lso cause buckling and the like with associated undesirable effects.
  • a sub-roof is commonly provided, often in the shape of a pliable web- shaped material. It is an object of the invention to simplify roofing to permit a wind screen, an air channelling system, and a sub-roof to be provided in one step.
  • Another object in this connection is to provide an element which may readily be transported and may be mounted in a simple and practical manner, and which especially is distinguished by the fact that in a mounted state to form an air channel and a wind screen it will have a rigid . shape which is capable of resistance, so that the hazard of buckling or being pressed upwards with resulting narrowing or destruction of the desired efficient passage of air is eliminated.
  • a sub-roof element which comprises a pliable web material and may form a sub-roof, the element according to the invention being characterized by the fact that it, furthermore, comprises a member provided from a foldable web material on the underside of the sub-roof, which forms air channels with closed cross sections.
  • said member is by the aid of folding indications divided into a number of parallel panels, so that it may be folded into an elongated unit with the flat panel sides in mutual contact, said member comprising two web members which are joined together along two opposed lateral edges in parallel with the folds, both web members having said folding indications for forming folds during folding operations, and with the height of fold ridges of one web member being lower than the height of those of the other web member.
  • said one web member When the member is stretched out of its folded position, said one web member will, thus, be tensioned into a substantially flat position, whereas the other web member Will still show folds.
  • the web member and the pliable web material In a state for transport the web member and the pliable web material will be folded and will, thus, require little space.
  • the web member is placed between rafters or corresponding elements and is stretched out into its full width and is fastened in place the pliable web material being tacked onto the rafters to form a sub-roof.
  • Said one web member will face the insulation, whereas the other, which still shows folds or stiffening ridges, will face the sub-roof placed on top.
  • the folds will provide very good stiffening and prevent the wind screen from buckling outwards or being displaced when insulation is placed towards the wind screen. Wind forces in the air channels will have no destructive influence on the wind screen exactly because- it forms a rigid structure. Consequently, a desired and fully efficient flow of the passing air is achieved.
  • the folds When used in a roof the folds will, additionally, provide an effect of a corrugated iron roof, since channels are formed which will provide good drainage for any
  • the folds of said two web members and the pliable web material may advantageously be directed so as to insert into each other during folding. This will especially result in a more compact embodiment for storage and transport.
  • the web members are joined at the fold bottoms - at least at every second bottom - in addition to said joining along opposite lateral edges.
  • the pliable web material forming the sub-roof may advantag- eously also be joined with both web members in a correspond ⁇ ing manner.
  • said one web member is made from a wind tight material which is pervious to moisture, e.g. brown wrapping paper, whereas the other web member may consist of a water repellent material or be provided with a water repellent coating on its outside, e.g. cardboard with a water repellent coating.
  • a wind tight material which is pervious to moisture
  • the other web member may consist of a water repellent material or be provided with a water repellent coating on its outside, e.g. cardboard with a water repellent coating.
  • any suitable plastic material which is used for sub-roofs at present may be used.
  • a special advantage that may be achieved by use of the invention, with said member made from paper and cardboard or a material with similar properties, is that the sub-roof element may be provided in full length without joints, e.g. for use between rafters in a roof. This is the case because the sub-roof element in a folded state may be folded across the folds . to provide an advantageous compact shape for transport. If joining should become necessary, nevertheless, this may be achieved in an advantageous manner by making one web member longer than the other one to permit an overlap, preferably with taping the overlap.
  • the pliable web material forming the sub-roof proper may also, advantageously, show an overlap.
  • the area along a rafter is an area requiring special consideration.
  • an air channel will form along the rafter, with the underlying insulation being bared.
  • an wind screen shaping body is advantageously provided to exten as much as possible at right angles to the overlying sub-roo formed by pliable web material at the fold portion extendin along the rafter.
  • the undesirable air channel will thus b reduced to a harmless minimum.
  • the sub-roof member may, also, advantageously be provide with adhesive strips for adhesion to the rafters.
  • the sub-roof elements are manufactured with width which is sufficient to cover the area between adjacent rafters.
  • the sub- roof element may be provided with a width which is sufficient to cover two adjacent areas as mentioned, the element thus being provided across three, if desired more, adjacent rafters.
  • Such a concept may be implemented by manufacturing the sub-roof element in a corresponding width or, e.g. by overlapping two elements of normal width at their edges and joining them during manufacture.
  • the rafter area generally requires special measures in order to protect the insulation.
  • a known concept is, e.g. to provide so called rafter cardboard.
  • the sub-roof element may have a flexible skirt at one end (the rafter end), or at both ends, both at the rafter end and the ridge end.
  • Such a skirt may readily be placed in front of the insulation in the rafter area, so that an efficient wind screen transition between wind screen, roof, and wind screen wall is achieved.
  • a skirt may, dependent on the kind of building, be -useful for preventing ventilation air from enterin into and mixing with the air which is present in the space in which the insulation is provided.
  • the skirt may, obviously, also be useful in case of joining.
  • the sub-roof element may, as mentioned, be folded transvers- ally to provide a suitably compact shape for transport.
  • readily foldable transversal areas may be provided, especially in the web member comprising stiffening, folds.
  • Such a readily foldable area or pane may, e.g. consist of a flexible plastic material, whereas the web member consists of rigid cardboard.
  • a sub-roof commonly provided by a plastic material will be slippery.

Web member 6 may also, preferably, be provided with folding indications. Pliable web material 4 commonly needs no special folding indications.
  • the sub-roof element may be manufactured at a length covering the entire roof dimension, from the ridge of the roof to the cornice, but if transversal joining is required, it may advantageously be achieved by transversal overlap joining.

Abstract

On associe une garniture interne pour toitures (4) à deux éléments en bande (5 et 6) fabriqués en papier/carton. L'ensemble se replie en un emballage allongé et peu encombrant que l'on peut plier transversalement selon le souhait. Un des éléments en bande (6) possède des crêtes formées par pliage dont la hauteur est inférieure à celle des crêtes de l'autre élément en bande (5), et il en est de même pour ladite garniture interne (4). Lorsque ledit emballage est déplié, ladite garniture et ledit élément (6) sont sensiblement plats, tandis que l'autre élément en bande (5) garde ses plis renforçants. On peut ainsi former, à l'aide d'un desdits éléments, une garniture interne possédant des fentes d'aération sous-jacentes et un écran de protection contre le vent au-dessus de l'isolation.
