Struct I APA rated sheathing is readily available and commonly used in California. Could be wrong, but it seems like most non residential structures, especially roofs, are using struct 1. Specifying as APA rated allows OSB or Plywood. So specify according to your belief in those products. ...
Combining flame-spread and burn-through resistance, LP® FlameBlock® Fire-Rated Sheathing is APA-rated OSB sheathing coated with a layer of noncombustible Pyrotite® fire-resistant cementitious material evaluated to help meet code requirements for fire-resistant construction while providing greater ...
light commercial construction. As a Structural 1 panel, this line of Blue Ribbon products has enhanced strength and stiffness characteristics. Each panel is third-party certified for quality and is rated for Exposure 1 bond durability for protected applications and limited exposure during normal ...

As the name implies, panels are intended for combination subfloor underlay and sheathing intended for roofs, walls, and subfloors. The products are rated for their particular end-use. The standards cover panels for supports spaced 400–1220 mm apart for floors and roofs. Provisions are also ...
Chapter 7 of the International Building Code (IBC) (refs. 2, 3) governs materials and assemblies used for structural fire resistance and fire-rated separation of adjacent spaces. This TEK is based on the provisions of Code Requirements for Determining Fire Resistance of Concrete and Masonry Const...
Contractors are FORBIDDEN from gluing the wall sheathing to shear walls without a review by an engineer. If that path is taken, the building has to be designed for over 4 times the seismic forces that it would without gluing it on. Again, this is not the same application, but it's a ...
The use of the skins, structurally, allows a reduction in size of the framing material, and the elimination of sheathing and interior finishing materials reduces the weight of the construction considerably. If it is desirable, the panels may be used only as a structural unit and any type of'...
or any publicly-attended facilities. It is ideal as a tackable wall and ceiling paneling, decorative or functional display wall and tack board, or tackable substrate for other fire-rated wall coverings. It can be used as a structural component (such as wall sheathing), or as noise-deadening,...
