Owens Corning is introducing FOAMGLAS® Perinsul® SIB (Structural Insulating Block), coming spring 2022.

As the AEC community looks to achieve ever more energy-efficient buildings, Owens Corning is introducing a solution to improve thermal performance, increase energy efficiency and minimize performance loss in the event of moisture exposure.

Owens Corning FOAMGLAS® Perinsul® SIB is a thermal-bridging solution for high-performance buildings. Material science helps explain its thermal performance. FOAMGLAS® Perinsul® SIB is a block made of cellular glass, enabling it to help eliminate thermal bridging beneath exterior masonry veneer walls. This thermal bridge near the foundation has historically been difficult to address due to the need for an insulating material that could meet both structural load and thermal performance requirements.

By achieving a continuous thermal barrier in various types of wall assemblies, FOAMGLAS® Perinsul® SIB protects against thermal energy loss at critical junctions. Cellular glass possesses impressive compressive strength and dimensional stability. To help protect against moisture, cellular glass insulation is nonabsorbent and impermeable to water. It will not shrink, compress or deform over time – even in extreme temperatures. And cellular glass insulation has long been trusted to defend against thermal bridging in high-performing buildings in Europe.

The compressive strength of FOAMGLAS® Perinsul® SIB contributes to a robust insulating material for use in masonry veneer walls that is lightweight and easy to install. It can support masonry veneer wall loads for low-rise buildings and does so with no deflection. 

Sizes match those of standard masonry blocks and are intended to abut end-to-end with no vertical mortar. Once installed, the product is designed to last the life of the wall and will not lose its thermal efficiency.

For North American specifiers and builders seeking materials that can help improve energy efficiency, reduce thermal bridging and defend against moisture, FOAMGLAS® Perinsul® SIB will be available in spring 2022.
