Definitions
- ABSTRACT A laminated roof construction and a method of forming the same wherein the roof comprises a supporting deck having a water-proof intermediate membrane upon which is superimposed a heat resistant sandwichtype foam panel.
- the foam panel consists of a cellular foam-like material such as polyurethane and similar substances, and this foam material has a top and bottom skin or film adhered to the foam. At least the top skin is weatherproof and is resistant to actinic rays.
- This invention relates to a roof construction and to a method of making such roof construction, and it particularly relates to an insulated, laminated type of roof construction.
- the water-proof membrane is directly exposed to light degradation, thermal shock, expansion and contraction under sun radiation.
- one object of the present invention to overcome the above and other defects of prior roof constructions by providing a laminated roof construction which is resistant to light degredation, thermal shock, and undue expansion and contraction under solar radiation.
- Another object of the present invention is to provide a roof construction of the aforesaid type which eliminates the necessity for using gravel or the like, and which is, therefore, lighter in weight.
- Another object of the present invention is to provide a roof construction of the aforesaid type which is relatively easy and inexpensive to repair.
- Another object of the present invention is to provide a laminated roof construction of the aforesaid type which is relatively inexpensive and which is relatively easy to manufacture and to apply.
- FIG. 1 is a perspective view of a roof construction with parts broken away.
- FIG. 2 is a perspective view similar to FIG. 1 but showing an alternative form of the invention.
- FIG. 1 a fragmentary portion of a roof construction, generally designated 10, which comprises a roof deck 12, made of either wood, metal, or a poured or precast concrete, gypsum board, plywood or any similar desirable rigid material.
- a roof deck 12 made of either wood, metal, or a poured or precast concrete, gypsum board, plywood or any similar desirable rigid material.
- the membrane 14 is a pre-formed, l-ply sheet fabricated from an elastomeric polymer such as ethylene-propylene rubber, Neoprene, styrene-butadiene rubber, etc.; or it may be fabricated from thermoplastic materials such as polyvinyl-chloride, polycarbonate, acrylonitrile-butadiene-styrene, stabilized polyolefins, polyvinyl chloride-polyacrylate alloys, Tedlar, etc.
- This membrane 14 is adhered to the upper surface of the deck 12 by any desirable adhesive 16.
- the membrane 14 is water-impermeable and acts as a very effective waterproofing agent for the roof.
- a heat insulating layer Connected to the upper surface of the membrane 14, by means of an adhesive layer 18, is a heat insulating layer.
- This layer comprises a so-called foam sandwich panel fabricated from a sheet of foamed polymer 20, preferably but not necessarily polyurethane.
- the center sheet 20 of foamed polymer is provided with an upper and lower skin, respectively designated 22 and 24.
- the foam sheet 20 may be of any suitable thickness, usually between about 0.5 inch and about 2 inches.
- the skins 22 and 24 may either be of the same or different materials. However, among the preferable materials for the lower skin 22 are, for example, metal foil such as aluminum, paper-reinforced metal foil, kraft paper, roofing felt, dimensionally stable polymeric films, or any other suitable material.
- the upper skin 24 may be of the same material or may be of such materials as supported fluoroplastics, for example, coated on metal foil, paper, or other suitable backing, such, for example as polytetrafluoroethylene, fiuorinated ethylenepropylene, chlorotrifluoroethylene and polyvinylidenefluoride.
- fluoroplastics are especially resistant to both actini'c rays and chemical action.
- other materials may be used such as, for example, polyvinylchloride and the like.
- the layer 20 is preferably constructed by prefabrication whereby the foam is extruded between the upper and lower skins while held against lateral foaming by opposed side walls. During the foam-forming and polymerization process, the foam sheet becomes integrally connected to the upper and lower skins-
- polyurethane foam is preferred for the heat layer
- other cellular foam materials may be substituted, as, for example, cellular polyvinyl chloride, polyolefins, polystyrene, styreneacrylonitrile copolymer, styrene-methylmethacrylate copolymer, etc. In all instances, however, it is required that the foam be sandwiched between upper and lower skins or films such as indicated at 22 and 24.
- the adhesive layers 16 and 18 may comprise such suitable agents as Neoprene, natural rubber, blends of natural and synthetic rubber, epoxy resin, polyurethane, polyacrylate, asphalt, polysulfide and the like.
- the membrane 14 has been described above as being constructed of a prefabricated elastomeric or thermoplastic sheet. However, it is also possible, and often preferable, to apply this membrane in the form of a liquid precursor, either by spraying, troweling, etc. This precursor subsequently polymerizes in situ to form the waterproof membrane.
- the precursor may comprise any one of a yariety of elastomeric or non-elastomeric substances, including either thermoplastic or thermosetting polymerizable substances, as for example, polysulfide, silicone polymers and the like.
- the liquid precursor may be already polymerized but carried in solution or emulsion form. These may be in solution in appropriate solvents.
- solvents which may be used on aromatic or aliphatic hydrocarbons; low molecular weight alcohols, preferably C to C ketones such as methyl isobutyl ketone'; glycols such as ethylene glycol monoethyl ether; esters; such as butyl acetate; or mixtures thereof.
- a liquid emulsion of a precursor of an elastomeric, thermoplastic or thermosetting polymer may be applied to form the waterproof layer on drying.
- the membrane 14 When the membrane 14 is applied in the form of a precursor or emulsion thereof, which cures or dries in situ, the adhesive layers 16 and 18 are omitted since the precursor or its emulsion acts as its own adhesive.
- FIG. 2 there is shown an alternative embodiment of the invention, wherein the roof construction is similar to the construction shown in FIG. 1, in that there is a roof deck 102 adhered to a membrane 104 by an adhesive 106.
- the membrane 104' is adhered by an adhesive 108 to the bottom skin 110 of a foam layer 112 having a top skin 114.
- the membrane 104 is a multi-layer assembly of alternate layers or plies of roofing felt and bitumen, the top and bottom plies being bitumen.
- the adhesive layers 106 and 108 are preferably bitumen.
- prefabricated foam sandwich panels would be used as separate sheets which are joined end-to-end by a suitable sealant or by tapes which are adhered over the joints.
- a laminated roof construction comprising a supporting roof deck, a water-impermeable membrane superimposed on said roof deck, and a heat and actinic ray-resistant panel superimposed on said membrane,
- said panel comprising a rigid cellular foam body having a top and bottom skin adhered to its respective upper and lower surfaces, at least the top skin being weatherresistant and substantially impervious to actinic rays.
- elastomeric polymer is a pre-polymerized emulsion polymer which forms the membrane by evaporation of the carrier.
- top skin is a fluoropolymer film.
- top skin is a member of the group consisting of metal foil and metal kraft paper laminates.
- a method of making an insulated laminated roof which comprises positioning a roof deck in place, ad-
