Fullback®V siding insulation provides vinyl siding with exceptional durability and strength, protecting your home against even the harshest elements.
Impact Resistant Durable Siding
Adding contoured EPS insulation behind quality siding significantly increases the impact resistance of the panel because the foam acts as a shock absorber to dampen the blow from objects like hail, baseballs, or rocks thrown from your lawnmower.
Siding Wind Rating
Fullback®V siding insulation eliminates the hollow void between your vinyl siding and the wall, which makes it more difficult for wind to get behind your siding. This eliminates rattling and provides your siding with extra durability against the toughest winds. Vinyl siding paired with Fullback®V can even sustain Category 5 Hurricane Winds!
Impervious to Water Damage and Rot
Fullback®V siding insulation channels bulk water out of the wall and allows air to move through the system, sufficiently drying the wall and eliminating the potential for expensive mold, mildew and rot problems.
Length of Siding Life
By adding high-quality, contoured insulation behind vinyl siding, you add strength to the product and reduce the possibility of the siding getting damaged by wind, debris and pests. The result is an extended life for your premium vinyl siding, backed by the strongest warranty in the industry.
