What it's used for
- Building fixed-light windows in timber garden offices, workshops, and home studios

Fitting and handling
Store this section flat and off the ground in a dry, covered space before use, and allow it to acclimatise to the ambient conditions of the installation site for at least 48 hours. When assembling a frame, cut the profile square or at 45 degrees at the corners and fix with exterior-grade PVA glue and galvanised lost-head nails or screws suitable for softwood. Finish with at least two coats of exterior-grade paint or primer before or immediately after installation to protect the timber from moisture ingress and movement.
FAQ
What glazing material fits the 10mm rebate on this window profile?
The rebate is sized to accept 4mm glazing material, including 4mm float glass, 4mm acrylic sheet, Perspex, and twin-wall or solid polycarbonate sheet. The remaining clearance allows for a standard softwood glass bead to be pinned in to secure the pane.
Can I use this profile for an opening window or casement?
This profile is intended for fixed-light, non-opening windows. It does not include a draught seal groove or hinge rebate, so it is not suited to casement or sash applications. For a fixed glazed panel in a shed, garage, or outbuilding it is a practical, straightforward choice.
Does this window profile come pre-treated or pre-primed?
No. The profile is supplied unfinished and unprimed. For any external application you should apply a suitable exterior primer or base coat on all faces, including the rebate, before fitting and follow up with a topcoat once the frame is in place.
