Rmax has launched Rmax Below Grade Polyiso Insulation for construction projects. The solution provides insulation and protection to below-grade foundation applications, while meeting energy code requirements.
With high thermal resistance, polyiso insulation is for exterior continuous wall and roofing applications, insulating against heat transfer. Rmax has now tailored polyiso for below-grade applications by incorporating a durable water-resistant facer onto the closed-cell foam core. This serves as a solution for below-grade applications.
“Historically, the vast majority of the below-grade commercial and residential foundations required a 2-in. thick XPS board to meet an R-10 code requirement in most markets, and 3 in. of XPS for R-15 in the northernmost markets. Our new product will meet the same R-10 requirement with only 1.5 in. of polyiso, which is 25% less material and achieve the same standard,” said Martin Heiskell, Sika’s SVP for Rmax.
