Definitions

  • This invention relates to an insulating sheet having a cellular structure, more particularly an insulating sheet of foam plastic material, suitable for use as a wall covering or for covering a reverse roof.
  • Insulating sheets of foam plastic are widely used as a wall covering in order to improve the insulation of houses and edifices.
  • these sheets are easily damaged and and thus these sheets have to be protected by applying additional materials, which involves high costs and is very labourious.
  • a reverse roof covering consists of a roof provided with a water proof layer such as a plastic foil layer or a bitumen layer, upon which one or more insulating sheets of foam plastic material having a closed cellular structure are provided.
  • Said known roof insulating sheet which is not being fixed to the subjacent foil layer or bitumen layer, has a relatively low weight and has therefore to be provided with a weighted layer, in the form of gravel.
  • Said gravel having a thickness of 5 cm which corresponds to 80 kg of gravel per m 2 , both provides a protection against UV-radiation acting upon the insulating sheet, and against a blowing away of the relatively light insulating sheets.
  • a gravel layer of this type has various different disadvantages.
  • the evenness of the gravel layer may be hampered as soon as anybody walks upon a similar roof, resulting in areas having uneven thicknesses, while additionally loose gravel tends to easily move, its free fall from a roof causing damages to vehicles, or injuries to persons.
  • the weight of gravel layers of this type is an additional disadvantage. Although the use of a similar layer is permitted when supporting a concrete roof, such a weight is cumbersome or even inadmissible when employing the same for steel roofs or wooden roofs. In renovation areas, where especially wooden roofs have to be insulated, it is mostly not permitted to use a similar gravel layer with a thickness of approximately 5 cm.
  • the present invention aims to provide an insulating sheet of the aforementioned type and consisting of material having a cellular structure which does not present the abovementioned disadvantages.
  • the sheet is provided with a weighting layer of weighting material affixed thereto and providing an additional weight of at least 5 kg/cm 2 .
  • Such an amount of weighting material provides on the one hand a sufficient protection of the insulating sheet of cellular material and on the other hand a sufficient weight when such sheets are used as a roof covering.
  • the weighting layer consists of weighting elements of stone, brick or ceramic material,such as stone or brick strips or ceramic tiles,and edge strips at at least one side of the sheet being free from weighting materials.
  • the weighting elements are preferably rectangular or square.
  • the width of said edge strip being free from weighting material is about half of the width of a joint between rectangular weighting elements, such as stone or brick strips or of ceramic material, preferably of a rectangular or square shape.
  • the weighting layer is preferably affixed to the sheet by means of adhesive in the form of an elastic mortar, said mortar advantageously being used for filling joints between successive rectangular or square weighting elements, if present.
  • Elastic mortars are able to adapt themselves to small changes of the sheet material.
  • the weighting layer of weighting material provides an additional weight of at least 2 2 10 kg/m and more preferably of at least 20 kg/m .
  • Said weighting layer of weighting materials having a thickness of only approximately 10 mm, provides the said additional weight of the insulating sheet to be installed upon a roof, thus eliminating any subsequent provisions such as those of providing a gravel layer.
  • the weighting layer of weighting materials preferably comprises aggregate particles projecting at least partially from a layer of adhesive material preferably an elastic mortar layer.
  • An insulating sheet of this type presents the advantage that as soon as the weighting layer of weighting materials has been provided, the sheets can be stacked upon eachother, as the presence of the projecting aggregate particles prevents a contact of the lower side of an insulating sheet with an as yet unhardened layer of elastic mortar of a subjacent insulating sheet.
  • Causing the gravel particles projecting from the mortar layer to form a substantially dense surface, will additionally provide an optimum protection against U.V.-radiation of the foam plastic material of the insulating sheet.
  • said elastic mortar layer may either or not, also comprise weighted ballast material and, more particularly ballast material with a high density, such as steel slag particles, ion ore particles, baryte and the like. Even in case that a layer of weighting material of this type has a slight thickness, in the latter manner the desired weighting layer is obtained.
  • the abovementioned insulating sheets have no longer to be provided with loose gravel, while no problems occur in any joints and the insulating sheets are very suitable for renovation purposes, more particularly for the insulation of wooden roofs, while the insulating sheets according to the invention can also be used for steel roofs of a more lower-weight construction.
  • Fig. 1 shows two sheets of foam plastic having closed cells and brick strips 3a affixed to the sheets 1 by means of an elastic mortar layer 2, which acts as an adhesive layer.
  • the strips 3a act as weighting elements and provide an additional weight of 7 kg/ m 2 .
  • the edge strips 9 of the sheets 1 are free from brick strips 3a, their width being half the width of the joint between two brick strips.
  • a space 11 bounded by the edge strips 9 of two successive sheets 1, is preferably filled with an elastic mortar.
  • Fig. 2 is another embodiment of an insulating plate 1, of foam plastic material and provided with an elastic mortar layer 2, formed from sand, mortar, water, and a latex and having a total thickness of 10 mm, so providing an additional weight of 20 kg/m 2 .
  • the thickness of said layer can be reduced to, for instance, 5 mm.
  • the elastic mortar layer provides a sufficiently weighted effect, thus precluding an insulating sheet loosely installed upon a roof, from being blown away.
  • Fig. 3 shows an other embodiment, consisting of an insulating foam plastic sheet 1, provided with a latex cement mortar layer 2, gravel particles 4 being embedded and affixed to said mortar layer.
  • the gravel particles 4 project at least partially from the surface on the latex mortar layer and form a substantially dense surface 5, thus preventing, even in case of little tears, occurring in the latex mortar layer, ultraviolet rays to degrade the foam plastic material of the sheet.
  • the gravel particles bear upon the surface 9aof the insulating sheet 1.
  • the total thickness of the latex mortar layer of 4 mm amounts, together with the gravel particles, to approximately 10 mm, and provides an additional weight comprised between 20 kg/m 2 to 25 k g/ m 2 .
  • Fig. 4 illustrates that the sheet 1 of fig. 3 provided with the latex mortar layer comprising embedded and attached gravel particles, is installed upon a foil layer 6, being adhered to a concrete roof 8, by means of an adhesive layer 7. Obviously, use can also be made of a self-adhesive foil layer.
  • said concrete roof 8 may also consist of wood or steel.
  • an insulating sheet according to fig. 3 additionally offers the advantage that small roof parts remaining uncovered after having covered said roof, may as yet be provided with portions of an insulating sheet 1, being provided in situ with a mortar layer 2, said mortar layer additionally being sprinkled with gravel particles.
