Huntsman Building Solutions Recognized by CCMC
BOISBRIAND, QC – April 5, 2023 – Huntsman Building Solutions (HBS) has received product code compliance (NBC 2015) recognition from The Canadian Construction Materials Centre (CCMC) for its Radon Protection System with a closed-cell polyurethane spray foam insulation product when used as an effective soil gas (radon) barrier in accordance with the recent 14280-R CCMC evaluation. Section 9.13.4.2.(1) of Division B of the NBC 2015 requires an effective air barrier system be installed as a barrier to soil gas. HBS’ Heatlok® Soya HFO, qualifies as protective air barrier systems for radioactive radon.
“We were the first spray foam manufacturer to test our products for radon diffusion more than 10 years ago, and the recent recognition by CCMC is the result of additional testing that we have completed,” says Maxime Duzyk, director of building science and engineering with Huntsman Building Solutions. “The key difference between our products versus others is that only 38mm of spray foam is needed for a solid soil gas barrier, versus other spray foam products needing 50mm. It means time and cost savings for architects, builders and contractors.”
HBS Heatlok® Soya HFO when installed at 38mm, show better resistance to radon than 6-mil polyethylene (that is, the NBC 2015 benchmark acceptable solution). The following were the key performance requirements for the evaluation of soil gas (radon) control beneath concrete slabs-on-ground and for wall, roof and floor assemblies:
- Material qualification: Medium-density spray polyurethane foam (SPF) complying with CAN/ULC-S705.1, and installation as per CAN/ULC-S705.2. Confirmed through possession of active CCMC Listing.
- Air barrier system: The air barrier system for floors-on-ground qualification through testing. The NBC 2015 benchmark is 6-mil polyethylene as per Sentence 9.25.3.6.(1) of Division B of the NBC 2015.
- Soil gas barrier: The barrier performance against soil gas, specifically radon, based on qualification testing, small-scale and large-scale. The NBC 2015 benchmark is 6-mil polyethylene as per Sentence 9.13.4.2.(1) of Division B of the NBC 2015, referring to Sentence 9.25.3.6.(1).
- Resistance to mechanical damage: Repeat small-scale radon-barrier testing with indented SPF by simulated concrete pour/workman load damage.
It is important for architects and builders to know that recognized spray foam insulation radon systems must be applied on site by qualified installers who are undertaking a 2-day training, run by members of the HBS tech department and engineering team, and a 3-day Caliber certification program. After passing an examination, attendees will receive an HBS Approved Applicator diploma as well as a Caliber certified installer license.
“Our research and development team are always innovating to ensure we provide exceptional spray foam insulation product meeting high quality standards for the needs of contractors, building design, and construction professionals that we serve. We are proud to offer products that multi-task and deliver on superior applications for radon abatement, energy efficiency and eco-friendliness,” says Duzyk.
