Why Choose Aluminium Window Sills?
Where Aluminium Window Sills Are Used
Aluminium window sills can be used on new homes, extensions, apartment blocks, commercial buildings, schools, offices, retail units, and refurbishment projects.
They are especially useful where a clean, consistent external detail is needed across several windows or where standard sills do not suit the project measurements. They can also be used as part of a wider aluminium package alongside cappings, louvres, rainwater goods, powder coated details, and roof edge profiles.
Window Sill Details That Matter
A good aluminium window sill needs to do more than look good. Projection, drip detail, end caps, fixings, colour matching, weather exposure, and water run off all need to be considered before fabrication and installation.
Correct detailing helps direct water away from the wall and reduces the risk of staining, water tracking, or damage around the window opening. C&S Roofing can fabricate sills to suit the building measurements and install them with the wider exterior finish in mind.
In House Fabrication for a Better Fit
Because C&S Roofing has its own fabrication workshop, aluminium window sills can be made to suit the exact requirements of the project. This is useful where the cills need to match specific measurements, colours, profiles, or other aluminium details on the building.
Keeping fabrication in house also helps with consistency across the project, especially where window cills need to line up with cappings, cladding, rainwater goods, or powder coated features.

The drip detail helps rainwater fall clear of the wall rather than tracking back towards the building. This can reduce staining and help protect the area around the window opening.
