Rmax®, a division of the Sika Corporation that specializes in developing and producing high-quality 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.
