Mount Airy, North Carolina - NCFI Polyurethanes's InsulStar spray polyurethane foam has received Florida building codes product approval. NCFI said the approval confirms that the product offers the highest wind resistance of any product currently approved for use in the state of Florida.
The testing showed that InsulStar used in triangular wedge-shaped fillets sprayed between the rafters and roof deck, without additional fasteners, provided a wind uplift resistance design pressure of 190 PSF, which NCFI said was greater than any other approved product in Florida. It can also be applied across the roof deck to act as a secondary water barrier, the company said in a 20 Oct news release.
"As pioneers since 1964 of spray polyurethane foam systems for commercial and residential building and roofing, we're not new to this. We take great pride in being first to market with the very best SPF products and putting them up against newcomers and foreign products coming into the market," said Mitch Clifton, senior manager with NCFI.
The Florida product approval system is in place to ensure creditability; a higher standard of practice for product evaluations and consistency of enforcement statewide, NCFI said in the statement.
NCFI of Mount Airy, North Carolina makes PU foam systems for spray foam insulation, roofing, marine floatation, packaging, speciality moulding amongst other uses.
