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 composite hydrophobic insulation textile with glass fibers and a first fluoropolymer. The first fluoropolymer and the glass fibers are interspersed with one another with sufficient uniformity to render the composite hydrophobic insulation textile as hydrophobic insulation and is temperature stable up to 600 degrees Fahrenheit.

The present invention relates to a non-woven fabric made of inorganic fibers, which has a coating of at least two layers on one of both surfaces, wherein (i) the non-woven fabric made of inorganic fibers has a thickness of at least 0.2 mm, (ii) the first layer of the coating comprises particles, whose particle size is between 50 and 100 m, (iii) the second layer of the coating, which is applied onto the first layer, comprises particles, wherein more than 90% of the particles have a particle size of less than 20 m. The non-woven fabric made of inorganic fibers according to the invention, in particular glass non-woven fabrics, are in particular suitable for producing decorative coatings for floor coverings, ceiling coverings and wall coverings.

Disclosed are compositions that can be used in forming products with increased near infrared (IR) reflective capability. A composition can include IR reflective and/or IR transmissive non-white pigments and can be formed with suitable viscosity so as to successfully coat substrates, e.g., yarns, suitable for use in forming coverings for architectural openings, e.g., window coverings. Also disclosed are textile substrates coated with the compositions, including textile substrates coated with compositions that in dude abrasive, inorganic IR reflective dark pigments.

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.

Hydrophobic thermal insulation fiberglass flexible blanket using a textile grade fiberglass is produced by impregnating a hydrophobic polymer (e.g. a fluoropolymer) dispersion into a fiberglass blanket/mat, such as a needle felted fiberglass (FG) blanket/mat. The preferred FG needle felt blanket is a mechanically, rather than organically, bound glass fiber insulating blanket. The hydrophobic polymer dispersion forms a hydrophobic coating on the surface of the fiberglass filaments. Integral hydrophobicity is achieved and maintained without the need to add commonly-used hydrophobic inorganic particles, such as treated silica aerogels or fumed silica. Optionally, to enhance overall hydrophobicity and to inhibit fibrous surface lofting, a super-hydrophobic coating of fluoropolymer and inorganic particles such as silica particles may be dispersed onto one or more surfaces of the blanket. The resulting blanket thermally insulates better than mineral wool; it is equal in insulating properties to (or is slightly better than) untreated FG mat; and it slightly less insulating than aerogel-based blanket materials. It is relatively inexpensive to manufacture, it is flexible, it is durable, it can optionally be made moldable, it eliminates dust, and it remains hydrophobic after long-term heating to 600 F. (315 C.), or after short-term excursions to temperatures as high as 700 F. (370 C.).

Disclosed are hydrophobic finish compositions and cementitious articles made with the hydrophobic finish compositions. In some embodiments, the article is a waterproof gypsum panel surface reinforced with inorganic mineral fibers that face a flexible and hydrophobic cementitious finish possessing beneficial waterproofing properties. The waterproof gypsum panels of the invention have many uses, such as, tilebacker board in wet or dry areas of buildings, exterior weather barrier panel for use as exterior sheathing, and roof cover board having water durability and low surface absorption. The flexible and hydrophobic cementitious finish can include fly ash, film-forming polymer, silane compound (e.g., alkyl alkoxysilane), an extended flow time retention agent including either one or more carboxylic acids, salts of carboxylic acids, or mixtures thereof, and other optional additives.

An aqueous finishing composition includes at least one polyglycerol, at least one organic polycarboxylic acid containing at least three carboxyl groups, at least one esterification catalyst, at least one plasticizer, and at least one thickener selected from a group consisting of cellulose derivatives, succinoglycans and xanthans.
