4
Hardware and gaskets are fitted
5
Glass is glazed in
6
The unit is fitted true and sealed in your opening

Questions

Frequently asked

Is the profile the same as the window?

No — the profile is the raw extruded uPVC system; the finished window is what a maker fabricates from it by cutting, welding, reinforcing, glazing, and fitting.

Can two makers using the same profile differ?

Very much — fabrication and fitting quality vary, so the same profile can produce very different windows.

Why does Glassterr fabricate in-house?

So the quality of the finished window — not just the profile — is in our hands from measurement to fitting.
