Abstract: A trilaminate a trilaminate shingle, having a horizontal longitudinal orientation, includes an overlay sheet having series of tabs and cutouts extending horizontally across the shingle. The shingle also includes a middle sheet having a series of tabs and cutouts extending horizontally across the shingle. The middle sheet cutouts are narrower horizontally than the overlay cutouts. The shingle also includes an underlay sheet beneath the middle sheet. The middle sheet is laminated beneath the overlay so that portions of the middle sheet, including at least some of the middle sheet cutouts, are exposed through the overlay cutouts. The underlay is laminated beneath the middle sheet so that portions of the underlay are exposed through the middle sheet cutouts and through the overlay cutouts. The exposed portions of the underlay sheet are generally darker than the middle sheet.

Abstract: A structurally enhanced, insulating sheathing (10) and method of sheathing a frame of the type used in constructing a building are disclosed. In one embodiment, the sheathing includes an insulating layer of material (14) attached to a structural layer of material (12) formed of a plurality of fibers (12al-12an), preferably biased in first and second directions (D1, D2) relative to a common axis, such as the longest centerline of the sheathing. The fibers form a grid (12c) having a plurality of openings (12d) that are capable of receiving an adhesive (A3) for attaching the sheathing to a stable mounting structure, such as a frame. Preferably, the adhesive is capable of penetrating at least partially into the openings to ensure that a secure, lasting bond is formed. In a second embodiment the sheathing includes a multilayer polymer film with a low melting point adhesive thereon.

The overlay member and/or underlay member may include a darker shading area to enhance the tile simulating aspect of the shingle.

Abstract: A formaldehyde free co-binder solution formed by using a polyol to crosslink polycarboxylic acid and a polyacid monomer is provided. In forming the co-binder solution, the polyacid monomer and the polyol are mixed in any conventional device with heat and agitation for a period of time sufficient for the chemicals to react and form a reaction product. The resultant product is then admixed with polycarboxylic acid to form a co-binder solution. In a preferred embodiment, the polyacid is maleic anhydride and the polyol is triethanolamine.

Abstract: A method of making shingles includes coating a shingle mat with roofing asphalt to make an asphalt-coated sheet, and covering the asphalt-coated sheet with granules to form a granule-covered sheet along a longitudinal axis, the granule-covered sheet having a shadow patch thereon, the shadow patch having a first width along the longitudinal axis.

Abstract: A construction beam includes a pair of lateral members and a resilient web extending therebetween, so as to present a cross-sectional profile corresponding to commonly used construction beams (e.g., 2″×4″ or 2″×6″). The resilience of the web helps to attenuate sound transmission through the beam from one lateral member to the other. In particular, in a wall frame, the lateral members are mounted at opposite ends thereof to end plates consisting of other construction beams according to the present invention. When the wall frame is used in a building structure, the lateral members of the end plates on the same side are attached to the surrounding structure, leaving the other side of the frame resiliently free floating. A wall is mounted on the free floating side of the wall frame so as to provide a resiliently free floating wall that acts as a sound attenuating absorber.

A rotary pattern cutter cuts a pattern of tabs and cutouts in the continuous granule covered sheet. The rotary position of the pattern cutter and the position of the timing marks are sensed, and the position of the continuous granule covered sheet with respect to the rotary position of the pattern cutter is synchronized in response to the sensed position of the timing marks and the sensed rotary position of the pattern cutter.

Abstract: The present invention generally relates to processes for preparing extruded foam products and more particularly to a process for producing such products wherein surface defects are minimized. There has been a movement to replace conventional halo-carbon blowing agents in favor of purportedly more environmentally safe halo-carbon free blowing agents such as carbon dioxide, nitrogen, argon, water, air, nitrogen, and helium. However, these halo-carbon free blowing agents, in particular carbon dioxide, have higher foaming rates and higher volatility leading to greater surface defects in the extruded foam. The present invention employs polyethylene wax to reduce or eliminate the occurrence of surface defects where halo-carbon free blowing agents are employed in an extruded foam manufacture process.
