Aluminium Window Sill Profiles

Sloped profiles fitted beneath windows and doors to carry rainwater away from the facade. The drip channel along the front edge prevents water from tracking back onto the wall surface. Continuous exposure to weather makes surface durability important.

Frequently asked questions

What slope should a window sill have?

The section must slope outwards so water drains away from the facade. The slope angles of our standard sections are given in the catalogue.

What is the difference between a sill and a drip profile?

A sill is the wide sloped section fitted under a window. A drip profile is the narrow channel that stops water tracking back along a surface; most sill sections already include a drip channel.
