THERMADRY® INSULATING DRAINAGE PANELS

THERMADRY Insulating Drainage Panels can be used below grade in residential and commercial applications including bridge abutments, retaining walls, earth-sheltered structures, culverts, lagging or forms.

Unique channels provide drainage.
THERMADRY Insulating Drainage Panels are manufactured with a series of closely spaced vertical and horizontal channels helping direct ground water flow to the drain. Adhered to the channeled surface is a spunbonded geotextile filtration fabric preventing soil from entering and clogging the channels.

Proven insulating performance
The thermal performance of STYROFOAM® brand extruded polystyrene foam insulation has been proven worldwide. The tight closed-cell structure resists all forms of moisture.

High compressive strength protects below-grade structures
STYROFOAM rigid structure assures high compressive strength that withstands installation abuse, earth pressures, hydrostatic pressures and freeze-thaw cycling.

The best choice for below grade insulation. Mineral wool and glass fiber drainage products deform when compressive load is applied. THERMADRY Insulating Drainage Panels, withstand compressive loads limits with deformation to less than 1.5% over a 20-year time frame. As a result, high drainage rates and insulative values are maintained.
