Disclosed herein is a method of manufacturing an improved cover board product with a panel. In some embodiments, the method includes preparing fragments into an assembly; mixing the fragments and an adhesive into a blended core furnish; applying the adhesive to a top side of a bottom layer fabric in the assembly; forming a core mat of the blended core furnish on top of the adhesive; applying the adhesive to a top side of the core mat; applying a surface layer fabric on the top side of the adhesive; pressing the assembly; and cutting and trimming the assembly to form panels.

This invention is a hip and ridge liner for a roof on a building. It is a waterproof and weather proof barrier that is installed on top of a hip line or a ridge line on a roof. Hip and ridge shingles are then installed on top of the hip and ridge liner. Embodiments of this invention include a plurality of external tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of internal tabs which function to securely retain the hip and ridge shingles and keep them in place for many years. Other embodiments of this invention include a plurality of shingle retaining clips which function to securely retain the hip and ridge shingles and keep them in place for many years.

A method is provided for forming an adhered membrane roof system that meets Factory Mutual (FM) 4470/4474 standards for wind uplift. The method comprises applying a bond adhesive to a substrate on a roof to form an adhesive layer and applying a membrane directly to the adhesive layer. The bond adhesive includes a moisture-curable polymer.

A synthetic nonwoven fabric having bonded fibers forming channels surrounding unbonded fibers forming raised slip resistant spots. The fabric is made by extruding hot polymer through a spinneret die onto a moving belt to form a sheet of random fibers, which sheet undergoes a calendering process between a pair of heated rollers, one of which rollers having a plurality of cavities defined in its surface. The resulting fabric can be laminated and otherwise combined with other layers as desired to provide an end product having good slip resistant properties.

In at least one embodiment, a microporous membrane having a moderate to high water vapor permeability and high liquid water penetration resistance is disclosed. The microporous membrane may be used in building applications, including as or as part of a building wrap, a rain screen, a roofing underlayment, a flashing, a sound proofing material, or an insulation material. The microporous membrane may include at least one thermoplastic polymer, at least one filler, and at least one processing oil. The microporous membrane may be flat or may have ribs. The microporous membrane may include at least one scrim component. A method for forming the microporous membrane is also disclosed.

A roofing underlayment comprising an exterior sheet with a fleece material having an embossed texture on a first and/or a second surface thereof. The fleece material comprises polyethylene terephthalate (PET). The exterior sheet may consist of the embossed PET fleece material, or comprise multiple layers which comprise the embossed PET fleece material arranged at an uppermost layer of the exterior sheet. A method of embossing the exterior sheet comprising the PET fleece material is also provided. Embodiments of the method involve using an off-line method of embossment, separate from the fabric production line, or an on-line method of embossment, to emboss the exterior sheet.

An ultra violet stable polyester membrane with a polyacrylic coating on one side and a coated pressure sensitive adhesive coating on its other side capable of allowing water vapor to pass through it. The pressure sensitive adhesive is formed of a copolymer comprising a backbone of n-butyl acrylate, 2-ethylhexyl acrylate, and vinyl acetate which is mixed with at least one surfactant and emulsified to produce air bubbles which form pores when the copolymer is set with about 80% to about 90% of the pore sizes ranging from about 200 microns to about 300 microns and being uniformly distributed to form a flow path through the pressure sensitive adhesive.

A cover board for use in a roofing system includes a core formed from recycled material. The core has a first major surface and a second major surface and the recycled material includes a plastic material. At least one region of the core has a concentration of plastic greater than a concentration of plastic within a remainder of the core.
