Reduce energy use, create a more comfortable home, and achieve lasting beauty

Beautiful Support

Adding insulation behind engineered wood helps level the wall behind the siding, making the siding appear even straighter.

Curb Appeal & Close Appeal

Linebacker features built-in alignment ridges to help make installation of engineered wood siding easier than ever before, guaranteeing a beautiful finished product.

More than aesthetics

Linebacker does more than help create a beautiful exterior.


Save Energy and Create a
More Comfortable Home

Linebacker adds an r-value of up to 3.9 to the siding, helping to save energy, reduce utility bills, and create a more comfortable home all year long! Adding insulation to the exterior of a home also helps dampen sounds from outside for a more enjoyable interior.

Protect Against Damage From Pests

Linebacker 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.


Take Control Of Moisture, Prevent Mold & Mildew

An average household produces 4-6 gallons of water vapor daily through activities like cooking & cleaning. Linebacker features a perm rating of up to 5.0, allowing moisture to escape the home. This reduces the chance of mold and mildew growth, creating a healthier home and longer lasting siding job.
