THERMADRY Insulating Drainage Panels are manufactured from 2' X 8'
panels of Dow Styrofoam® brand extruded polystyrene insulation. Closely
spaced vertical and horizontal channels cut into one side of the THERMADRY panels provide rapid drainage. Adhered to this channeled surface is a spunbonded
geotextile, filtration fabric which helps prevent soil from entering and clogging
the channels. This fabric also overlaps the sides and ends of the panels.
This prevents the edge channels from being clogged at the panel joints. Tongue
and groove edges on each panel help assure a tight fit.
The closed-cell structure of Dow Styrofoam enables THERMADRY panels to repel
all forms of moisture. In addition, its rigid structure assures high compressive
strength that withstands installation abuse and geopressure.
This unique time- and labor-saving product provides drainage, reduces long-term
energy consumption and protects a building's foundation. THERMADRY's high
drainage rates and high compressive strength protect below-grade structures
against the potentially damaging effects of soil water, hydrostatic pressures
and freeze-thaw cycling.
The ability of THERMADRY to withstand compressive loads also limits compressive
creep deformation to less than 1.5% over a 20-year time frame. As a result,
high drainage rates are maintained. The thermal performance of extruded polystyrene
foam insulation provides predictable, long-term insulation value.
There are three types of THERMADRY Insulating Drainage Panels — Type 750,
Type 1250 and Type 1750. Each can be used to full advantage in varied structures
other than basements or foundation walls. They will, for example, drain, insulate
and protect bridge abutments, retaining walls, earth-sheltered structures, culverts,
lagging or forms. And Types 1250 and 1750 can be also be used for horizontal
installations such as plaza decks.
THERMADRY Insulating Drainage Panels should not be
exposed to petroleum solvents or fuels, and should be protected from prolonged
sunlight exposure to prevent ultraviolet degradation.
