A shingle comprises an overlay, an underlay, and a height increasing material disposed between the overlay and the underlay. The height increasing material includes a first adhesive adhered to the overlay, height increasing granules adhered to the first adhesive, and a second adhesive adhered to the height increasing granules and the underlay. The height increasing material can extend along front ends of tab portions of the overlay, along front cutout edges that extend between tab portions of the overlay, or both.

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.

A nonwoven carrier for bituminous membranes, wherein the nonwoven includes organic polymer fibers and is consolidated with an aqueous binder, wherein the binder includes starch and polyvinyl alcohol, which includes up to 5 mol. % of other monomer units, wherein the binder does not include a crosslinker, and the binder does not include a filler.

The invention relates to a novel binder system and its use for bonding textile fabrics as well as products containing such bonded textile fabrics. The materials according to the invention are suitable for manufacturing base interlinings which may be used for manufacturing base interlinings for sarking, roofing and sealing membranes, particularly for manufacturing coated sarking, roofing and sealing membranes.

A glass mat includes an assembly of glass fibers, a binder composition and an asphaltic coating. The binder composition includes an organic resin and an adhesion promoter. The glass mat has an at least 2% increase in tear strength as measured using the methods specified in ASTM D3462, compared to an asphaltic coated glass mat having a binder composition without the adhesion promoter. Further provided is an asphalt roofing product including the glass mat and a method of increasing tear strength in an asphalt roofing product.

An asphalt coating for roofing waterproof membranes is provided and comprises: from about 30 to about 88 weight percent (wt %) of asphalt; from about 0.1 to about 15 wt % of a low molecular weight (MW) polyethylene; from about 1 to about 30 wt % of a thermoplastic elastomer; from about 5 to about 48 wt % of an inorganic filler; and from about 1 to about 20 wt % of a softening agent; all based on the total weight of the asphalt coating.

The invention relates to a sealing membrane for a roof, comprising: an upper layer made from a polymer material, a lower sealing layer arranged to cover the roof, and a reinforcement disposed between the upper layer and the lower layer, characterised in that the polymer material is bi-oriented.

A bituminous membrane comprising a nonwoven support which is impregnated with bitumen and a binding resin. The binding resin is for nonwoven fabrics, in particular, for manufacturing supports for bituminous membranes, having natural, sustainable raw materials. The resin is an aqueous solution including starch, a crosslinking agent of natural origin, a catalyst and optional additives.

A bituminous tile with grit coating may include: a support layer including a base layer made of non-woven glass fiber fabric, having a first major surface to which a glass fiber net is coupled which covers at least 80% of the first major surface; a first external bituminous layer covering the net and the first major surface; a second external bituminous layer covering a second major surface of the base layer, facing away from the first major surface; a grit including ceramized colored mineral granules, covering the second external bituminous layer. A method for producing such a bituminous tile may include: (a) impregnating the support layer at 120-180? C.; (b) covering the impregnated support layer with non-adhesive bituminous compound at 170-210? C. to define the first and second external bituminous layers; (c) depositing the grit on the second external bituminous layer at 120-170? C.; (d) cutting the covered support layer to obtain tiles.

Asphalt sealcoats and asphalt shingle waste coatings for roofing materials are provided. A roofing material comprises a substrate having an exposed surface and an unexposed surface. An asphalt shingle waste coating is located on at least a portion of the exposed surface of the substrate. The asphalt shingle waste coating comprises an asphalt shingle waste, wherein the asphalt shingle waste comprises a waste asphalt and a limestone. An asphalt sealcoat is located on at least a portion of the asphalt shingle waste coating. The asphalt sealcoat is substantially free of the asphalt shingle waste. The asphalt sealcoat has a thickness of no greater than 50% of a thickness of the asphalt shingle waste coating.
