Over 300% greater than ASTM impact standards
DuraPlank is the thickest panel (.054”) on the market and features an Energy Star rated extruded foam backing for straighter walls, enhanced energy savings, sound deadening performance and greater home comfort.

Featuring the WindLok 265 System
Innovative double nail hem enables panels to withstand winds up to 265 mph*. This exclusive WindLok 265 System provides a more secure, tighter-fitting siding that stands up to the highest standards of structural performance.

*In testing, DuraPlank installation system achieved a test pressure of 187.72 lb/ft. 2. This equates to a wind speed of 265 mph.

Extra Think Gauge (.054”)
Thickest panel on the market offers superior rigidity and strength.

Free-Floating Foam
Foam is locked, not glued, to allow for expansion, contraction and escape of moisture for a lifetime of performance.

Ventilating Air Pockets
Creates an efficient thermal barrier and helps protect against rot, mold and mildew.  

Effective Water Channels
Water and condensation are collected and guided away from internal walls. Helps prevent water from pooling behind siding, which can lead to rot, mildew and thermal breakdown.

DuraPlank Outperforms

Brick
Won't spall, crack or crumble like traditional brick and mortar.

Aluminum
Will not peel, dent or show scratches like aluminum siding.

Fiber Cement
Will not crumble, crack or absorb moisture and will not require painting or caulking of unsightly seams.

Wood
Will not rot, split or warp like wood and never needs painting.

Ribbed Foam by GreenGuard®
DuraPlank’s uniquely ribbed foam backing has been cleverly designed to provide maximum impact resistance and great sound deadening qualities. Rigid construction ensures DuraPlank won’t follow curved walls and it can easily withstand high humidity, salt air, and freeze/thaw cycles. Installation is safer and easier because it produces no harmful dust (silica); the panels are light, do not have to be kept dry, and won’t warp, crack, crumble, collapse, or shift.

Reinforced siding ensures straight walls and maximum impact resistance.

Unlike most other vinyl siding and foam-backed cladding systems, DuraPlank has individual 7” courses. As a result, DuraPlank seams are less apparent and naturally staggered, giving your home a beautifully clean finish and a natural wood look.
