When we got a call from Zylstra Harley Davidson in Dallas Center, Iowa, requesting more information about HY-Fi, our revolutionary hybrid insulation system, we knew this would be the perfect application for HY-Fi. The issue Zylstra Harley Davidison was having was the cost to insulate a large commercial showroom to R-21 specifications. Enter HY-Fi. With only 2" of closed cell foam blown in the wall cavaties, they quickly installed a layer of R-8 HY-Fi directly onto the studs that allowed them to reach R-21 at a lower cost than what SPF alone would have cost. In addition to reducing heat flow by radiation, HY-Fi’s multiple layers also reduced convective heat transfer. Combining HY-Fi’s superior radiation protection with traditional insulation in a hybrid system created superior resistance to heat transfer that allowed Zystra to efficienctly control the temperature within their showroom. Project Solution: The R-21 wall insulation system specifed was a hybrid application consisting of 2” of closed cell spray foam and HY-Fi, a multi-layer reflective insulation. Combining the technologies provided a more cost effective air sealing and thermal insulation system than spray foam alone.
