Royal DuraPlank is an exceptional high performance panel designed to enhance the beauty, comfort
and energy efficiency of any home. Noted for its traditional wood clapboard appearance, extra thick profile and straight,
flawless finish, this reinforced siding features a rigid foam backing that insulates, repels moisture and maximizes rigidity.
As a result, Royal DuraPlank offers the industry’s highest impact resistance as well as unmatched protection under the
harshest weather conditions. Available in a wide variety of popular standard colors as well as UV-resistant Colorscapes™
shades for long-lasting color retention, Royal DuraPlank perfectly captures the look, feel and rigidity of natural wood—and
comes with a powerful color retention warranty.
Revolutionary color technology combines Luran® S ASA, BASF’s premium color-fast thermoplastic, with Royal’s
innovative Royalside™ Compound and Dura Technology™ Process
Provides industry leading UV resistance and fade protection
Weatherable thermoplastic blocks out the sun to protect dark colors, providing homeowners with a wider color selection
Over 300% greater than ASTM impact standards Royal 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, the Royal DuraPlank installation system achieved a test pressure of 187.72 lb/ft². 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.
Royal 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® Royal DuraPlank’s uniquely ribbed foam backing has been cleverly designed
to provide maximum impact resistance and great sound deadening qualities. Rigid construction ensures Royal 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, Royal DuraPlank has individual 7” courses. As a
result, Royal DuraPlank seams are less apparent and naturally staggered, giving your home a beautifully clean finish and a
natural wood look.
