Composite/PB consists of Atlas closed-cell polyiso bonded
to 1⁄2" perlite on the top and a fiber-reinforced felt facer on
the bottom. The perlite top eliminates the need for cover boards
or vented base sheets normally recommended over foam insulations.
ACFoam Composite/PB may be used with BUR,modified bitumen,and
single-ply systems. 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. |
