Freezermate™ XPS Insulation

Commercial | Residential | Multifamily | Wall

Foam boards engineered to beat the cold

A sturdy subfloor thermal insulation that resists moisture and freeze-thaw cycles. Freezermate™ XPS Insulation is a rigid Styrofoam™ Brand solution designed for low-temperature application while delivering high R-values.


Freezermate™ XPS Insulation

Freezermate™ extruded polystyrene (XPS) foam insulation a Styrofoam™ Brand solution for use as subfloor thermal insulation in low-temperature applications. It features smooth, high density skins with excellent insulating characteristics, high resistance to water and water vapor, excellent freeze-thaw resistance, superior compressive strength and long-term durability. Freezermate™ Insulation can also be used in most static and dynamic loading situations for flooring applications. Because the rigid foam insulation boards resist even severe forms of moisture penetration in freezer and cooler construction, they offer long-term R-values superior to other types of thermal insulation.

    1 Not all product sizes are available in all regions.

    2 R means resistance to heat flow. The higher the R-value, the greater the insulating power. R-values are expressed in ft²•h•°F/Btu. R-value determined by ASTM C518.

    3 Vertical compressive strength is measured at 10 percent deformation or at yield, whichever occurs first. Since Styrofoam™ insulations are visco-elastic materials, adequate design safety factors should be used to prevent long-term creep. For static loads, 3:1 is suggested. For dynamic loads, call 1-866-583-BLUE (2583) for safety factor recommendation.

    4 Water vapor permeance varies with product type and thickness. Values are based on the desiccant method and they apply to insulation 1” or greater in thickness.
