Window sills

Aluminium window sills are essential components used in window installation to provide a functional and aesthetic transition between the window frame and the exterior wall. Here at Alupress our sills are complete with welded end caps and upstands, we can manufacture sills up to 4000mm long, welded bay window sills and curved sills. Here’s some information about them:

Material and Construction:

  • Aluminium window sills are typically made from folded aluminium profiles, which offer strength, durability, and corrosion resistance. Alupress sills are complete with welded upstands and stop ends. This prevents water ingress at the reveals and provides a clean contemporary finish to the ends.

  • The profiles may feature various designs and shapes depending on the architectural style and functional requirements of the building.

  • Aluminium sills are available in a range of powder coated RAL colours to match the aesthetics of the window frames and the building facade.

Features and Benefits:

  •  Weather Resistance: Aluminium window sills provide protection against moisture infiltration, preventing water damage and mold growth inside the building.

  • Durability: Aluminium is inherently durable and resistant to corrosion, ensuring long-term performance and minimal maintenance requirements.

  • Lightweight: Aluminium is lightweight yet strong, making it easy to handle and install during window installation and replacement.

  • Customisation Options: Aluminium sills can be custom-made to suit specific project requirements, including dimensions, profiles, and finishes.

  • Aesthetic Appeal: Aluminium sills provide a sleek and modern appearance, enhancing the overall look of the windows and the building facade.
