Versatex calls its Stealth group of soffits, fascia and frieze boards the first such system of its kind in cellular PVC. The vented soffit's 1/8-inch grooves are specially designed to keep out insects, while the venting pattern provides 10 inches of free airspace per lineal foot. Versatex says that when the soffit, fascia and frieze are used together, the interlocking system and tight fit save builders time and labor costs. 724.857.1111.
