ACFoam II features ACUltra Technology which means ZERO HCFC´s - a cost effective "Green" building solution. Excellent R-Values reduce energy demands while maintaining compatibility with all types of roofing membranes and fire assemblies. ACFoam-II is offered in a variety of thicknesses, providing long-term thermal resistance (LTTR) values from 6.0 to 25.0. ACFoam-II is a closed-cell, polyiso core integrally laminated to heavy black (non-asphaltic), fiber-reinforced felt facers. ACFoam-II is also available in 25-psi formula. Available in 4´ x 4´ (1220mm x 1220mm) and 4´ x 8´ (1220mm x 2440mm) panels.

In 1998, years ahead of the Environmental Protection Agency timetable for eliminating HCFCs (hydrochlorofluorocarbons), Atlas introduced a line of ACFoam Products that are environmentally sensitive and available for virtually every type of construction system. Through a patented hydrocarbon blowing technology called ACUltra, Atlas began the phaseout of HCFCs in the manufacturing of foam insulation and anticipates the complete removal of HCFCs from all Atlas foam products within the next year.
