Owens Corning Launches FOAMULAR® XPS RadonBarrier™ Radon Abatement System

Insulation system designed to make Canadian homes safer sets a new benchmark for radon gas encapsulation

Owens Corning, manufacturer of PINK® FIBERGLAS® insulation and other energy-saving products, is pleased to announce the launch of its new CCMC certified FOAMULAR® XPS RadonBarrier™ Radon Abatement System.

Radon is a radioactive gas that is odourless, colourless, and tasteless. When radon is released into the atmosphere it gets diluted and poses negligible risk to human health. However, if radon accumulates inside a home, it can pose a serious health risk. According to a Toronto Star article published May 2, 2021, radon is the second leading cause of cancer, after cigarette smoking*.

About one in five homes — 5,600 of the 30,000 tested nationwide — showed radon levels exceeding Health Canada’s guideline of 200 becquerels per cubic metre (Bq/m³), according to data gathered by researchers from the University of Calgary conducting this investigation. The radon threat could be neutralized with simple and affordable technology at time of construction.*

“The innovative Owens Corning radon barrier system is a smart choice in new construction. It helps protect the homeowner from radon gas entry and helps create the ultimate lower living space — providing comfort, indoor air quality, and most importantly, a safer living area,” said Sal Ciarlo, technical services and codes & standards director.

Owens Corning is proud to introduce an energy-efficient and sustainable solution for radon abatement:
