Below Grade Insulation

Rmax

Rmax®, a division of the Sika Corporation that specializes in developing and producing insulation solutions, has launched Rmax® Below Grade. This innovative insulation solution provides superior insulation and protection to below-grade foundation applications while meeting energy code requirements.


Renowned for its high thermal resistance, polyiso insulation is historically a popular choice for exterior continuous wall and roofing applications, enhancing the energy efficiency of buildings by effectively 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, ensuring the optimal solution for below-grade applications.


“Historically, the vast majority of the below-grade commercial and residential foundations required a 2″-thick XPS board to meet an R-10 code requirement in most markets, and 3″ of XPS for R-15 in the northernmost markets. Our new product will meet the same R-10 requirement with only 1.5″ of polyiso, which is 25% less material and achieve the same standard,” said Martin Heiskell, Sika’s SVP for Rmax.
An additional advantage of the Rmax Below Grade resides in its positive environmental impact, which requires 25% less material, fewer truckloads and less floor space per square foot of inventory compared to other below-grade insulation options.
