Reduced Frost Penetration Thermaguard TG-250

You need a sturdy, durable foundation that stands up to the elements.

Nordic Void ThermaGuard TG-250 is made from an olefin polymer that has an additive, which reduces thermal conductivity and improves load bearing and long term creep resistance.

It serves as an insulating flanking material around the perimeters of concrete foundations to reduce the amount of frost penetration underneath to the slab.

BENEFITS

Gear Points

Nordic Void ThermaGuard TG-250 incorporates all the benefits of Nordic Void Form while improving thermal insulation and lasts for multiple compression cycles, unlike single cycle polystyrene void form.

Protect

Prevents thermal transfer, diminishes conductive heat loss, reduces heave.

Withstand

Designed for resilience using closed-cell polyethylene foam. Holds up to frost heave and soil swell and remains stable over a range of temperatures.

Resist

Resists insects, vermin, moisture, mold, frost, bitumen, oil, hydrocarbon and diesel fuel.

Fit

Planks can be bonded to others to perfectly fit your project regardless of thickness or shape. Does not require protective OSB or plywood cover.

Perform

Strong, flexible, polyethylene foam that withstands temperatures. Easy to use and maintains its durability.
