Dolly Varden ®
Dolly Varden is a classic tongue & grooved Western Red Cedar Paneling that uses Shakertown’s 60 years of experience to laminate cedar to exterior backing. This system provides you a stronger, more durable engineered paneling with qualities not found in solid cedar.
- Composition and Materials: Dolly Varden Tongue and Groove cedar panels are composed of genuine Western Red Cedar and fir bonded with exterior adhesives (under pressure) into an exclusive 7-ply engineered panel. The bonding method of full surface gluing meets the weather test and other requirements for exterior siding as specified under U.S. PS 1-09. Insulation values up to R 1.65 are superior to other siding products.
- Finishes: Manufactured in laminated natural Western Red Cedar. Products may be sealed or stained in the field, or factory pre-finished.
- Basic Uses: For exterior paneling on walls or soffits. For interior walls or ceilings.
- Limitations: May not be used as a substitute for shear panel, although may be used over shear panels.
- Nails: Use of proper nails is important. For exterior applications use a non-corrosive fastener; stainless steel, hot-dipped galvanized or aluminum. Fasteners must be of sufficient length to penetrate into nailable wood, a minimum of 1-1/4”. A stainless 6d splitless siding nail is preferred.
