Standard Specifications & Dimensions

Our sills are prefabricated to your specifications for a simplified installation process.

• Material Thickness: The standard profile is 1 cm (approximately 3/8 inch). This sleek dimension provides a modern aesthetic while ensuring robust durability for long-term performance.
• Custom Sizing: We cut to order based on your provided window measurements. Typical depth (overhang) ranges from 10 cm to 20 cm (4 to 8 inches), allowing for a classic and proportional appearance.

Available Surface Finishes

Select the finish that best matches your design vision and practical requirements.

Polished Finish

Creates a high-gloss, reflective surface that intensifies the marble's vibrant color and detailed veining. Ideal for achieving a luxurious, formal ambiance.

Honed Finish

Provides a smooth, satin-matte appearance for understated sophistication. This finish is more forgiving of daily wear, showing fewer fine scratches and smudges than polished stone.

Textured Finishes (Flamed/Brushed)

While less common for interior use, these options offer enhanced slip resistance and effectively conceal surface marks. They impart a rustic, natural character to the stone.

Core Advantages

• Inherent Elegance: Every piece is unique, showcasing the organic patterns and color variations of natural marble.
• Superior Durability: A strong, long-lasting material perfectly suited for the demands of a window sill application.
• Installation Ready: Prefabricated according to your dimensions for a straightforward fitting process.
• Design Versatility: The warm orange tone complements a wide spectrum of color palettes and architectural styles.

Professional Installation Guidance

We understand that actual wall conditions may vary. For a perfect fit, we recommend this professional approach:

• Always Dry Fit First: Position the sill without adhesive to assess the fit against the window frame and identify any gaps or angle discrepancies.
• On-Site Customization: Our 1cm thickness allows skilled installers to make precise adjustments using appropriate wet-cutting equipment. Ends can be scribed to match uneven wall angles perfectly.
• Sealing Gaps: Minor spaces between the sill and wall can be neatly filled with color-matched silicone caulk or professional stone adhesive, ensuring a clean, waterproof seal.
• Expert Recommendation: Employing an installer experienced with natural stone is advised for optimal results and handling.

Ordering Information

Please contact us with your exact window measurements for a precise quotation. Due to the natural characteristics of stone, each slab is one-of-a-kind; reviewing multiple pieces is recommended if seeking a specific vein pattern match for your project.
