How to measure
- Measure the depth from the window frame to the finished façade.
- Choose the overhang in front of the façade, usually 30 to 50 mm.
- Measure the length in the reveal; side end caps are extra.
Installation: end caps, expansion and noise reduction
Side end caps: for a render or brick finish, fit end profiles onto the ends of the window sill. Subtract their size, usually a few millimetres per side, from the reveal width. The sill with its end caps then fits the reveal exactly.
Expansion: metal moves with temperature. With a 50 °C difference, aluminium expands by around 1.2 mm per metre, stainless steel by around 0.8 mm. Allow a little clearance at the end caps. Split very long window sills into two parts and join them with a butt connector that takes up the expansion.
Noise reduction: an anti-drumming strip on the underside dampens the drumming of rain. Stick it on across the length before installation, every 30 to 50 cm or so.
Fixing: the rear upstand meets the window frame and is screwed to it. The underside rests on the insulation or in a bed of adhesive. The outward slope and the drip edge, at least 20 mm from the façade, drain the water away safely.
