Leaside Exterior Window Sill
$81.97 per 8' Length ($10.25/Ft)
The Leaside is a substantial high-profile exteriorwindow sill designed for projects requiring a sense of structural permanence. Its commanding recessed box geometry mimics massive hand-cut stone blocks, featuring a steep beveled wash for high-performance drainage.
This profile can be custom modified or shaped into arches to suit site needs. It provides a maintenance-free, luxury masonry aesthetic ideal for grounding large window assemblies in stone or brick veneers with advanced composite durability.
DAVIDE'S SUGGESTED STYLE KIT
Material Summary
- Core: Lightweight, high-density EPS foamcore
- Reinforcement: Alkali-resistant fiberglass mesh
- Finish: Proprietary polymer-modified cement finish
Engineered for zero-joint expansion and 100% moisture resistance.
Technical Specifications +
- Core Material: High-density expanded polystyrene (EPS) core protected by a proprietary polymer-modified cementitious coating (approx. 3/16 inch thick).
- Thermal Stability: Engineered for zero-gap joint integrity; thermal expansion coefficient optimized to resist shrinking or cracking during extreme North American freeze-thaw cycles.
- Bonding Technology: Bond ready surface optimized for high-strength architectural masonry adhesives; compatible with EIFS, brick, stucco, and stone substrates.
- Weight & Structure: 90% lighter than traditional pre-cast concrete (approx. 1/10th the weight), eliminating the need for heavy-duty structural wall reinforcement or mechanical hoisting.
- Finishing Options: Arrives in a uniform cement-gray finish that acts as a premium masonry primer; compatible with all high-quality exterior acrylic latex paints and textures.
- Technical Customization: Precision factory-cut to any architectural profile; capable of achieving true arches, ellipticals, and bespoke geometric shapes that traditional materials cannot replicate.
- Environmental Durability: 100% inorganic and inert; naturally resistant to moisture, wood-boring insects, rot, and UV degradation for a maintenance-free lifecycle.
