A system for introducing a noise-dampening polymer in-line in the manufacturing process of a manufactured wood product to achieve higher acoustic performance in siding, sheathing, roofing, flooring, and similar applications using the manufactured wood product. Several lines or bands of the noise-dampening polymer are deposited transversely across one side or face of the product. The polymer is deposited where the product is expected to contact joists or studs. The polymer may be a viscoelastic polymer.

Building or structural panels may be joined, such as to form walls or floors. The panels may be connected in various orientations via one or more connectors. The connectors may mount to anchors associated with the panels. The panels may have outer skins located over an expanded core comprising a matrix of supporting elongate members and voids or openings, with the anchors located at edges of the panels.

A multilayer thermal insulation panel for construction and manufacturing method thereof are described. The multilayer thermal insulation panel comprising: a main layer in thermally insulating material comprising a first surface and an opposite second surface; a first backing layer of the main layer connected to the main layer along the first surface; a second backing layer of the main layer connected to the main layer along the second surface. At least one of the first and second backing layers comprising: a reinforcement layer in fibrous material, a fire-resistant layer comprising expansive graphite, and a cladding layer made on the reinforcement layer and configured to be sandwiched between the fire-resistant layer and the reinforcement layer.

Waterproof engineered floor and wall planks have a veneer layer bonded with a plastic composite core, and an underlayer, preferably an underlayer of cork.

Apparatus and methods for constructing a shower pan. The shower pan is constructed from wedge panels having a foam core and facers on major surfaces of the wedge panels. The wedge panels are cut into portions that fit regions of the shower pan area. The wedge panel portions are placed in the regions such that the sloped upper surfaces of the wedge panel portions collectively form a continuous surface that at all locations slopes downward toward the drain of the shower. Pans for a wide variety of shower shapes and sizes can be constructed. The shower pan may be efficiently constructed on-site, often using common tools and techniques.

The present invention relates to an improved formaldehyde-free coated fibrous substrate. The coating includes a crosslinked binder system which forms three dimensional networks when heat cured. After the coating is applied to the back of fibrous substrate and cured, the coating is capable of hygroscopic expansion which imparts excellent anti-sag properties. The coating is compatible with other coating systems with neutral or mild alkaline pH. The improvement being the binding system is neutralized with a volatile base so that it evaporates quickly so as not to hinder the cross-linking reaction.

Described herein is a coated building panel having a body and a surface coating atop the body, the surface coating comprising inorganic pigment and a polymeric dispersant comprising a polymer backbone and pendant side chains extending from the polymer backbone; wherein the surface coating comprises a liquid carrier in an amount less than about 1 wt. % based on the total weight of the surface coating.

Described herein is an stain and sag resistant acoustic building panel comprising a porous body formed from building material and latex binder, wherein the building material may include fibers and filler and at one of the building materials has been pre-treated with a charge-modifying component, thereby enhancing the sag-resistance of the building panel.

A sheathing panel includes a barrier overlay secured to a panel; wherein the sheathing panel is bulk water resistant and has at least one of the following properties: a water vapor transmission rate of at least 7.0 grams per square meter per 24 hours (grams/m.sup.2/24 hours) as determined by ASTM E96-15 procedure A at 73° F. and 50% relative humidity (RH), a water vapor permeance of at least 1.3 perms as determined by ASTM E96-15 procedure A at 73° F. and 50% relative humidity (RH), or an air infiltration rate of less than 0.2 liters per second per square meter (L/s-m.sup.2) at 75 pascals (Pa) as determined by ASTM E2357-11.
