Product Description
Foam Insulation Drainage Board 1 in x 4 ft x 4 ft R-4 GPS HalfBack H20®
Adding Halfback H20 siding insulation helps level the wall behind new siding, reducing the visibility of imperfections in the wall that otherwise might create a less-than-perfect appearance.
Halfback H20 siding insulation is treated with PREVENTOLTM EPS, a safe insecticide which protects the foam from termite damage. This provides an extra layer of defense between your home and mother nature.
Halfback H2O siding insulation is available in both white expanded polystyrene (EPS) and graphite-enhanced Neopor. Neopor provides up to 20% more insulating value than standard EPS, allowing for more energy savings with the same amount of material.
