DuraPlank House

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




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


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.

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.
