Styrofoam™ Brand Panelmate™ Ultra

Commercial | Residential | Multifamily | Wall

Moisture-resistant protection for basement walls

Designed for exterior foundation walls, Perimate™ XPS Insulation provides a lightweight, durable system that protects the waterproofing membrane while it fends water drainage away from the foundation.


Styrofoam™ Brand Panelmate™ Ultra

Styrofoam™ Brand Panelmate™ Ultra is designed specifically for insulated precast concrete panels that require above-average thermal performance. It uses patented carbon black materials in the foam for greater thermal performance over other extruded polystyrene insulations. This enhanced formulation helps the foam to absorb infrared radiation, slowing its transmission through the foam and lowering heat flow.
