4 ways to reduce energy costs in commercial buildings
Our history includes thousands of successful projects with our XPS (extruded polystyrene) product line. As one of the standards in the industry, rely on GreenGuard for your wall, roof, and below-grade applications with a high R-value of 5.
GreenGuard XPS is a closed-cell foam. This tight configuration gives it the highest water resistance of commonly available insulations. Water passing through foam decreases the foam’s effectiveness as an insulator as well as opens up the opportunity for damage to the building. This is why XPS is the standard product for many applications below-grade as well as above-grade walls and protected membrane roofs or plaza decks.

Insulation has the positive benefits of making buildings more efficient and less reliant on the use of energy to keep them comfortable.


Now Kingspan GreenGuard LG XPS insulation boards use a blowing agent blend of less than 50 GWP and zero ODP. Specifically, all LG XPS Insulation Boards are free of HFC 134a. All Kingspan Insulation products are also free of HBCD fire retardant.
