Described herein is a building panel comprising a body, the body comprising: a fiber; a latex binder present in an amount ranging from about 3 wt. % to about 10 wt. % based on the total weight of the body; and an inorganic particle having an average particle size ranging from about 1 micron to about 13 microns; wherein the inorganic particle and the binder are present in a weight ratio ranging from about greater than 1:1 to about 6:1.

A composite roofing membrane containing a single ply roofing membrane containing a first membrane, a scrim, and a second membrane. The first side of the first membrane forms the upper surface of the composite roofing membrane and contains a thermoplastic polymer. The scrim has a machine and cross-machine direction and contains a yarn or fiber selected from the group consisting of polyester and glass, and a tensile strength in the machine direction is at least about 100 N/cm.sup.2. The second membrane contains a thermoplastic polymer. The composite roofing membrane also contains a fire resistant fleece containing a plurality of FR rayon staple fibers and a plurality of char scaffold fibers selected from the group consisting of partially oxidized acrylonitrile and silica staple fibers.

A natural fabric or textile product is coated and protected with a waterproofing composition comprising a crosslinking polyvinyl acetate (XPVAc or x-PVAc) emulsion polymer or adhesive applied and cured as a first coating layer or a primer and a coating layer of acrylic, alkyd, asphalt, emulsion polymer isocyanate, epoxy, lacquer, latex, polyurethane, urethane, or vinyl ester coated over the cured crosslinking polyvinyl acetate as a second coating layer or a topcoat. The natural fabric product is fabricated by weaving, knitting or felting the fibers, yarns or threads of vegetable or plant fibers from cotton, sisal, kenaf, hemp, jute, flax, reed, sugarcane, ramie, henequen, raffia, nettle, milkweeds, palm, coir, grass, Spanish moss, New Zealand flax, kapok, sugarcane, bamboo, or wood, or those of the protein fibers from wool, silk, spider threads, sea silk, or the combination thereof.

The present invention relates to a textile fiber structure comprising man-made fibers fortified by a binder comprising a polymer latex obtained from the emulsion polymerization in aqueous medium of a mixture of ethylenically unsaturated monomers comprising: (a) an aliphatic conjugated diene (b) a vinyl aromatic compound; (c) an ethylenically unsaturated silane bearing at least one silicon bonded hydrolysable group, and (d) an ethylenically unsaturated acid
and to its use in construction applications, and to the use of the above binder to fortify textile fiber structures.

The invention relates to a waterproof membrane for building applications comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane. The invention also relates to a waterproof membrane comprising at least one support carrier and at least one layer of a cross-linked coating composition comprising at least one polyurethane, an optional pre-coating layer to facilitate the manufacturing process, and to join the support carrier with the cross-linked coating composition in the most optimal and durable manner to achieve good surface appearance and chemical bonding between reinforcing carrier and crosslinked polyurethane coating. The waterproof membrane can be prepared and installed with lower cost in comparison to current flat roof waterproofing systems based on liquid two-component polyurethane systems.

Disclosed is a shingle that uses a polyester sheet as a substrate layer. The polyester sheet has a sufficient weight and is needled and formed from two layers to resist shrinking upon cooling after the heated asphalt layers are applied to the polyester substrate sheet 102. In addition, additives may be included in the asphalt to lower the softening point temperature of the asphalt that further reduces shrinking of the polyester substrate 102 or allows other polymers that are more fire retardant to be used. Fire retardants can be placed in the polyester sheet fibers, placed in the bonding agent for the polyester fibers, or the polyester sheet can be coated with the fire retardant. Alternatively, or in addition to treating the polyester sheet 102 with fire retardant, fire retardant materials such as ammonium sulfate can be added to the liquid asphalt prior to application of the asphalt layers.

A method for preparing a roofing membrane in the form of a roll, comprising the steps of: providing a polymeric membrane; providing a fabric having a coating disposed thereon; attaching the polymeric membrane to the fabric to form a composite; and rolling the composite. Wherein the coating includes expandable graphite dispersed within a binder.

A fiber mat includes an assembly of fibers including a minority portion including a set of polymer fibers and a majority portion including a set of fibers different than the minority portion, wherein the minority portion is a plane parallel to a plane of the majority portion of the assembly of fibers; and a binder including an organic resin, wherein an air permeability of said fiber mat is not substantially different from an equivalent weight fiber mat containing a homogenous mat structure and wherein the fiber mat provides at least a 5% increase in tear when placed in a bituminous roofing product compared to an equivalent bituminous roofing product made with the equivalent weight fiber mat containing the homogenous mat structure.

The invention relates to a sealing element comprising at least 20-60 wt % of PVC resin, and 20-45 wt % of a biobased plasticizer.

Some embodiments of the present disclosure relate to an roofing shingle comprising a low penetration point asphalt reinforced glass mat. In some embodiments, the reinforced glass mat comprises a glass mat and a reinforcement material. In some embodiments, the glass mat comprises a web of glass fibers. In some embodiments, the reinforcement material is embedded into the web of glass fibers of the glass mat. In some embodiments, the reinforced glass mat comprises a sufficient amount of the reinforcement material, so as to result in a nail shank shear resistance of 13 lbs to 17 lbs, according to ASTM 1761 at 140? F. Methods of making the roofing shingle and methods of forming a roofing shingle from the roofing shingle are also disclosed herein.
