Save Energy and Create a
More Comfortable Home

Protect Against Impact Damage and Pests

The contoured shape of FullbackFC completely fills the gap behind the siding, serving as a shock absorber to help protect fiber cement siding from impact damage. Filling the gap also eliminates space where pests can nest behind the siding, and Fullback is treated with a safe insecticide to protect it from termites.

Take Control Of Moisture, Prevent Mold & Mildew

An average household produces 4-6 gallons of water vapor daily through activities like cooking & cleaning. FullbackFC 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.
