What is Quad-Lock made of?
The panels are made from safe, non-toxic, fire-retardant EPS (expanded polystyrene) and the ties are made from HDPE (high-density polyethylene). Quad-Lock panels contain no CFCs, HCFCs, polyisocyanurates, or other toxic chemicals. They do not “off-gas” or break down over time. • Is a Quad-Lock building safer than a wood-framed building? Yes, reinforced concrete walls are up to 8.5 times stronger than wood-framed buildings. As a result, Quad-Lock walls are far more resistant to earthquakes, tornadoes, and hurricanes. In addition, Quad-Lock walls have been tested and shown to be an effective 4 hour firewall. Quad-Lock walls, however, are only one component of the building so you should make other building components disaster resistant as well, e.g. floors and roofs. • What happens to Quad-Lock walls in a fire? Concrete structures are far more likely to remain standing through a fire than structures built with wood. Quad-Lock walls have been tested and shown to be an effective 4 hour fire
