Sill Profiles
The Finishing Detail That Makes the Difference. Precision at the Base. Protection That Lasts.
A complete window system is defined not only by its frame and sash, but also by the details that ensure long-term performance, weather protection, and architectural continuity.
Fineastra Sill Profiles are engineered to integrate seamlessly with Fineastra window systems, delivering efficient water management and a refined finishing solution for both standard and thermal installations. Manufactured using high-quality aluminium alloys and finished to perfection, each sill profile is available in a full range of RAL powder-coated, anodized, and woodgrain effect options — delivering long-term performance and visual harmony in every architectural context.
The collection includes a comprehensive range of standard aluminium sill profiles from 75 mm to 250 mm in 25 mm increments, providing suitable solutions for a wide variety of wall constructions and architectural applications. To support the growing demand for high-performance thermal window systems, Fineastra is also introducing a new family of Thermal Sill Profiles — initially available in 150 mm and 240 mm widths.
