Benjamin Moore Celect Canvas Horizontal Lap 7″ Siding

Benjamin Moore Celect Canvas Horizontal Lap 7″ is a paintable cellular PVC siding that solves the moisture trap problem traditional siding creates while offering double the insulation value of standard products. R-value is approximately double that of standard siding materials. Built with Patented Interlocking Joint [REMOVED]Boards lock top-to-bottom and side-to-side to eliminate gaps and visible seams., this system means no caulking at joints — ever.

For Montana contractors dealing with 100+ freeze-thaw cycles annually and extreme temperature swings, this material addresses the core challenge: keeping water out while letting structures breathe. The Gravity Lock Design: Ensures courses remain straight and resists buckling or warping due to thermal expansion. That matters when temperatures swing 60 degrees in a day.

Installation Specifications That Matter

Panel length: 12’ 4” (3.15 m), with 14 pieces per carton covering 100 sq. ft. Each panel provides a 7-inch exposure with nominal thickness: Approx. 0.45” - 0.50”.

The installation process leverages that interlocking system. Panels lock into place, maintaining alignment and a moisture-tight barrier. Critical detail: Requires a 1/8-inch expansion gap at ends and around fixtures. Skip that gap and thermal expansion will buckle the installation.

Performance in Montana Conditions

This siding handles Montana’s punishment. Tested to withstand wind loads exceeding 210 mph. The cellular PVC construction means Resistant to rot, termites, mold, and moisture; no organic material to decay. No wood means no food for carpenter ants — Montana’s real wood-destroying pest.

Celect is significantly lighter, easier to handle, and offers better thermal insulation (2x R-value). compared to fiber cement. Weight matters when crews haul materials up ladders in July heat or October wind.

The material is 100% recyclable. White cellular substrate designed for low heat absorption and high dimensional stability. That white core reflects heat rather than absorbing it — less expansion and contraction stress.

Paint System Requirements

Canvas series comes unpainted, designed specifically for field painting. Requires ‘Vinyl-Safe’ paint with a Light Reflectance Value (LRV) of 50 or higher (some guidelines suggest 57+).

Compatible paints include:

• Benjamin Moore Aura® Grand Exterior
• Benjamin Moore Regal® Select Exterior High Build

Celect Canvas Horizontal Lap should be painted after installation using vinyl-safe coatings. Paint it wrong with standard exterior paint and heat absorption will warp the siding. While the factory-finished Celect line carries a 25-year color warranty, the unpainted Canvas series relies on the warranty of whatever paint system gets applied in the field.

Bottom Line

Benjamin Moore Celect Canvas works for contractors who understand that eliminating caulk maintenance saves callbacks. The interlocking system genuinely eliminates joint gaps. Double R-value provides measurable energy savings. Limited Lifetime Warranty covering manufacturing defects, including rotting, corrosion, and cracking.

Not the cheapest option upfront. But for Montana builds where maintenance access is difficult — mountain homes, remote properties, tall gables — the no-caulk joints and rot resistance justify the investment. The 210 mph wind rating handles anything Montana throws at it.

FAQ

What makes this different from regular vinyl siding? Offers a much thicker profile, superior impact resistance, and a more realistic wood texture with better color longevity (when used with Kynar or proper paints). The cellular PVC core is completely different from hollow vinyl profiles.

Can this handle Montana’s freeze-thaw cycles? The Gravity Lock Design: Ensures courses remain straight and resists buckling or warping due to thermal expansion. Combined with required expansion gaps, the system accommodates extreme temperature swings without buckling.

Does it really eliminate caulking? Boards lock top-to-bottom and side-to-side to eliminate gaps and visible seams. Eliminates the need for caulking at joints, reducing maintenance and improving aesthetics. The interlocking design creates the seal mechanically.

What warranty coverage does the unpainted Canvas line have? Limited Lifetime Warranty covering manufacturing defects, including rotting, corrosion, and cracking. Color warranty depends on the paint system applied by the installer.

Is special trim required? Fully compatible with Celect color-matched trim, mounting blocks, and gable vents. Standard J-channels and starter strips work with the system.
