Mastic Quest Vinyl Siding (Non-Weathered) PVC siding with dimensions of 144" x 10"

OSFM names that model under 8140-2070:0004 and identifies SFM 12-7A-1 as the test protocol. The non-weathered qualifier is part of the cited product description and should remain with the model when comparing the proposed siding to the listing. It supplies no finding about weathered specimens to add to that description.

The handbook refers detailed construction to Ply Gem's installation instructions and product data sheets. It gives no backing thickness, fastening schedule or separate flame-spread class for this model. A useful specification therefore carries the Quest identity, the non-weathered qualifier and the stated dimensions into that document review, then confirms the exact GOVmotus listing. The named PVC siding is the subject of the listing, rather than every vinyl product sold by Ply Gem.
