Nanosilver for use as a biocide in coated fibrous substrate facers and other construction and/or building substrates, for protection against bacteria (particularly cyanobacteria), fungi, molds, algae and other bio-organisms known to deface and/or adversely affect such building materials. Facers referred to are commonly used in the construction industry as exposed surfaces for insulation and sheathing boards.

Nanosilver as a biocide in building materials

This invention relates to a low fiber, pliable composite mat product suitable for use in the construction industry, particularly as an interlayer in roofing between a weathering course, e.g. a shingle and structural decking, e.g. plywood, which is a dry preformed fiber mat containing a binder for the fibers, preferably a preformed glass mat, surfaced or coated on both sides with a prefoamed composition which contains a cured polymer latex, and, preferably, a foam sustaining amount of a surfactant and a flame retarding and/or strengthening amount of a mineral filler, and also to the use and process for the preparation of the above.

Composite mat product for roofing construction

This invention relates to a low fiber, plyable facer suitable for use in the construction industry, particularly for insulation board manufacture, comprising a dry preformed fiber mat containing a binder for the fibers, preferably a preformed glass mat, coated with a prefoamed composition which contains a polymer latex, a foam sustaining amount of a surfactant and a flame retarding and/or strengthening amount of a mineral filler and also to the use and process for the preparation of the above as well as to a siding underlayment or insulation board having a foamed, thermosetting resin core which is surfaced with said facer as a product for commercial use.

Foamed facer and insulation boards made therefrom

This invention relates to a low fiber, plyable facer suitable for use in the construction industry, particularly for insulation board manufacture, comprising a dry preformed fiber mat containing a binder for the fibers, preferably a preformed glass mat, coated with a prefoamed composition which contains a thixotropic polymer latex, a foam sustaining amount of a surfactant and a flame retarding and/or strengthening amount of a mineral filler and also to the use and process for the preparation of the above as well as to a siding underlayment or insulation board having a foamed, thermosetting resin core which is surfaced with said facer as a product for commercial use.

Foamed facer and insulation boards made therefrom cross-reference to related patent application

This invention concerns a light weight sheet felt material suitable for use as roof and siding underlayment and insulation board facing which comprises on a dry basis

Sheet felt

A device for the spot application of molten asphaltic composition to spot locations comprising a rod of solid, modified bitumen adapted for heating and end thereof. The softened or molten composition at the end can easily and conveniently be delivered to spot locations.

A solar roofing assembly is provided including a roofing membrane, a plurality of insulation blocks disposed as a layer on top of the roofing membrane, a plurality of pavers disposed as a layer on top of the plurality of insulation blocks, and a plurality of photovoltaic cells, each supported on a respective paver. In a second embodiment, each paver has a respective photovoltaic cell bonded to the top surface of the paver and has a respective insulation block bonded to the bottom surface of the paver forming a shop assembled, three-layer unit. The insulation block is also tapered with one side edge being thicker than an opposite side edge so that rain water will run off the top surface of the photovoltaic cell. The three-layer paver units are arranged on top of the roofing membrane, so that the top surfaces of the photovoltaic cells face south or in the direction of increased sun exposure. The insulation blocks have interlocking side surfaces. The joints between the pavers and the insulation blocks permit drainage therethrough of rain water for flow of rain water over the top of the roofing membrane. A method of manufacture is provided, wherein three-layer units of insulation block, paver and photovoltaic cell are made in the shop, and wherein the three-layer units are installed in the field over a field-installed roofing membrane.

A process and apparatus is provided for making a rubber-like product from rubber scrap, such as recycled tire scrap. The process includes mixing the rubber scrap with from 1 percent to 15 percent, with respect to the weight of the rubber scrap, of added sulphur, and applying a pressure thereto of about 1000 to 3000 pounds per square inch for 1 to 10 minutes at a temperature of from about 250 degrees F. to about 450 degrees F. In addition, 1 to 8 percent, with respect to the weight of the rubber scrap, of antioxidants and antiozonants are added to the mixture of rubber scrap and sulphur. The sulphur is free sulphur. Derivative sulphur compounds, or like vulcanizing agents, can be added in place of the free sulphur of about 1 to 45 percent of the weight of the rubber scrap. The rubber scrap is buffing of recycled tire rubber, or powder made from recycled tire rubber. An apparatus for carrying out the process is also provided. The apparatus includes a heavy duty mixer for making the mixture of the rubber scrap and sulphur and antioxidants and antiozonants. The apparatus also includes a compression molding and heating apparatus for applying the pressure and temperature to the mixture. The process is particularly suitable for making roofing products.

Process for preparing a rubber scrap composition

Polyisocyanurate foam in which the polyol content is largely a polyol mixture prepared by the transesterification with a glycol of a residue obtained from the manufacture of dimethyl terephthalate and in which the foam has been prepared using fluorocarbon blowing agent and amine triol to improve compatibility between the polyol and the blowing agent.

Polyisocyanurate foam

Polyisocyanurate foam in which the polyol content is largely a polyol mixture prepared by the transesterification wtih a glycol of a residue obtained from the manufacture of dimethyl terephthalate and in which the foam has been prepared using fluorocarbon blowing agent and amide diol to improve compatibility between the polyol and the blowing agent.

Polyisocyanurate foam and reaction mixture for making same

Polyisocyanurate foam in which the polyol content is largely a polyol mixture prepared by the transesterification with a glycol of a residue obtained from the manufacture of dimethyl terephthalate and in which the foam has been prepared using fluorocarbon blowing agent and alkoxylated alkyl amine to improve compatibility between the polyol and the blowing agent.
