ThermaDry Insulating Drainage Panels are manufactured with a series of closely spaced vertical and horizontal channels that help direct ground water flow to the French drain. Adhered to the channeled surface is a spunbonded geotextile filtration fabric preventing soil from entering and clogging the channels.
Mineral wool and glass fiber drainage products deform when compressive load is applied.ThermaDRY panels withstand compressive load limits with deformation to less than 1.5% over a 20-year time frame. As a result, high drainage rates and insulation values are maintained.
