Atlas Web Technologies provides the roofing industry with a coated fiberglass facer (CGF) that is applied to foam panels thus giving superior dimensional stability, increased wind uplift, water resistance, fire resistance as well as many other benefits. WEBTECH CGF provides superior weather resistance that allows commercial and residential builders to apply the insulation panels with little to no cupping or bowing. Testing of WEBTECH CGF shows it will not support the growth of mold and mildew.
Extruded polystyrene (XPS) foam insulation is a rigid, closed-cell foam product that can be used in various applications for insulating building foundations. Foam plastics are composed of millions of tiny cells or bubbles. Closed-cell foam, so called because the cells are intact with no holes or spaces between them, is stronger in bending and compressive strength than open-cell foam in which the cells have holes connecting one cell to another. In addition, XPS tends to maintain its R-value over time due to its moisture resistant properties.
