Quebec, Canada – The latest spray foam product from Huntsman Building Solutions (HBS), Heatlok Soya HP, uses the latest version of Honeywell’s Solstice liquid blowing agent. The closed-cell foam is claimed to have the best R-value of any currently available HFO product, with an LTTR value at 50mm of 2.06 RSI – an R-value of 11.68.
HBS carried out several demos with contractors to ensure the product better met their needs. “The benefit of doing the demos together was to understand their pain points and deliver on a spray foam product that they are accustomed to using, but that provides an upgrade in the application process and the insulation value,” said Jean-Francois Lupien, global director for product management at HBS.
The Canadian-made spray foam includes 20% recycled plastic and renewable soya oil. It has low VOC emissions, and has been awarded GreenGuard Gold certification. Applications include roofs, walls and sub-slabs. HBS said the foam is also appropriate for cathedral roofs, where ventilation can be difficult.
It is an all-in-one product that provides insulation, a rain screen, and both air and vapour barriers, reducing the need for separate barrier membranes. It is also resistant to fungus, mould and flood damage.
Up to eight inches can be sprayed in a single day, with a high compressive strength of 37psi. It is compatible with most building products, and can seal the junction and joints of a range of different materials.
