Flush Casement Windows

They can be, but it depends on the local planning authority and whether the property has any specific restrictions. The flush profile, mechanical jointing, deep bottom rail and period hardware options give the best chance of getting approval on sensitive jobs.

If a customer is in a conservation area or dealing with a listed building, always advise them to confirm with the local planning officer before ordering. We can supply to whatever spec is needed once you get confirmation.

On a standard welded window, the corners of the frame are fused together with heat. Mechanical jointing uses physical corner fixings instead, which creates a small visible gap at the corner, which is exactly what you see on original timber windows.

It is worth specifying on jobs where authentic period aesthetics matter, particularly where the customer or planner is likely to look closely at the corners. On most residential replacement jobs a welded finish is fine and easier to produce.

Both the Liniar and Profile 22 flush casement systems achieve an A+  Energy Rating with double glazing as standard. The multi chambered profiles trap warm air within the frame, keeping heat in and reducing energy loss.

Triple glazing is available where the job calls for it, pushing thermal performance further for customers in exposed locations or where planning requires higher standards.

Both systems offer a range of period and contemporary hardware. Traditional options include monkey-tail handles, dummy peg stays and astragal bars for that authentic timber look. Modern handle styles are available where the customer prefers a cleaner finish.
