Royal's TMQ451P Oracle Quad 4.5-inch insulated vinyl siding with ASA capstock is listed within a specified wildfire-area wall assembly.
The model in 8140-2339:0502 uses nominal 2-by-4-inch studs, spaced 16 inches on center, and 5/8-inch Type X gypsum sheathing. Tyvek house wrap is secured by staples to the gypsum. Galvanized roofing nails attach the siding: their length is 1-1/2 inches and their spacing is 16 inches on center.
The insulated siding description still includes that backing and wrap. Its ASA capstock and TMQ451P identity should remain explicit in the specification, along with the framing and fastener schedule. OSFM identifies SFM 12-7A-1 for the described construction and refers additional details to Royal's installation instructions and product data sheet. Confirm the complete Oracle model designation through GOVmotus when checking the proposed wall.
