News Story: Quad-Lock says its six-inch load bearing walls have achieved a three-hour fire rating from UL/ULC, while its four-inch wall received a two-hour rating and its eight-inch wall received a four-hour rating.

Quad-Lock officials hailed the results on the six-inch wall because the tests were conducted on what he called an “ordinary” wall without fibers in the concrete mix.

“Our results, by the leading fire testing agency in the world, fly in the face of other studies that have been conducted,” said Douglas Bennion, Quad-Lock’s Training & Technical Services Manager. “This may suggest that those studies need to be revisited.”

Quad-Lock Building Systems Ltd. manufactures and distributes Insulating Concrete Form (ICF) systems for walls, floors and roofs. Quad-Lock ICFs are made with high density, fire retardant expanded polystyrene (EPS) beads. They contain no formaldehyde, CFCs or HCFCs. Quad-Lock’s wall systems have four panel types, two panel sizes, 10 wall configurations and virtually limitless wall thicknesses, resulting in R-values ranging from R-22 to R-40.
