December 2000
Made from 100 percent postconsumer plastic, the CavClear masonry
mat and insulation systems are made to facilitate drainage
and ventilation within masonry walls. The recycled plastic
is fashioned into fluid-conducting, nonabsorbent, mold- and
mildew-resistant polymer mesh and bonded to extruded foam
board insulation.
Hebel Building Systems

Autoclaved aerated concrete (AAC) blocks from Hebel offer
significant energy and maintenance savings over many ordinary
block framing systems. Without additional insulation, a Hebel
wall can reduce heating and cooling costs over ordinary insulating
systems. This efficiency is due to a combination of high R-value,
thermal mass, and air-tightness. AAC production is low in
energy consumption and raw material usage. Manufacture produces
no environmentally toxic by-products.

The company's autoclaved aerated concrete (AAC) blocks are
is made from sand, water, and limestone. The raw materials
are processed to create a structural building material with
a large number of pores, known as aerated concrete. One unit
of volume of the raw materials yield five units of volume
of Ytong. Insulation value, due to pores, is high, while the
product is light and easy to work with.
