Deevale Exterior Window Sill
$51.61 per 8' Length ($6.45/Ft)
The Deevale is a slimline exterior window sill designed for minimalist masonry aesthetics and limited-space applications.
Featuring a compact 4 inch height and a shallow 2.25 inch depth, it has the look of a traditional cut stone "slip sill".
The profile has a sharp, singular sloped wash and a clean vertical face, with a functional drip edge on the underside so moisture is shed away from the wall.
Material Summary
- Core: Lightweight EPS foam core (ASTM C578 Type I)
- Reinforcement: Alkali-resistant fiberglass mesh
- Finish: Polymer-modified cementitious coating, approx. 3/16 in thick
Engineered for near-zero joint expansion and moisture-inert performance.
Technical Specifications +
Profile: 4 inches high, 2-1/4 inches top depth, 1-1/4 inches bottom depth.
Core Material: EPS foam core (ASTM C578 Type I) with a polymer-modified cementitious coating, approx. 3/16 in thick, reinforced with alkali-resistant fiberglass mesh.
Moisture & Movement: Moisture-inert core that won't rot; near-zero joint expansion; designed for freeze-thaw exposure.
Weight: A fraction of the weight of precast concrete. Standard lengths can be installed by one person, with no heavy wall reinforcement or lifting equipment.
Installation: Exterior adhesive, with mechanical fasteners where the Mouldex installation guidelines require. For stucco, EIFS, brick, stone veneer, siding and ICF.
Finishing: Arrives in a uniform cement-gray finish. Prime, then paint with a quality exterior acrylic latex paint or texture.
Fire: Fire-rated options are available on request with a Class A fire rating (flame spread 25, smoke developed 110) that helps meet ASTM E-84 and UL 263.
Customization: CNC-cut to custom profiles, arches and ellipticals, typically within 7 to 10 business days of design approval.
