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

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. |

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 GreenGuardŽ 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. |

Seams like real wood. Individual Courses Eliminate Unsightly
Stacked Seams
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.
