How well it keeps the heat in
Uw of the whole window: frame, glass and spacer together.
- uPVC, 5 chambers, double glazing 1.30 W/m²K Replacing old joinery in a block of flats.
- uPVC, 6 chambers, triple glazing 0.90 W/m²K A house you heat yourself.
- Aluminium with a thermal break 1.50 W/m²K Large shopfronts and wide openings.
Uw changes with the size of the window: the same frame with the same glass gives a different Uw on a small opening than on a large one.
Questions before you order
What people ask us most often, on the phone.
Can I measure the openings myself?
You can, for a price estimate. The order only goes into production on our measurement, because a one-centimetre mistake in production cannot be fixed afterwards.
What is the difference between Ug and Uw?
Ug is the heat transfer of the glass, Uw that of the whole window, frame and spacer included. We write both and mark every time which one it is.
Is triple glazing worth it everywhere?
No. In a flat on district heating the difference on the bill is small. In a house you heat yourself, you feel it.
Who carries away the old joinery?
We take it out and carry it out of the house. If you want us to take it to the recycling centre too, that is listed separately in the quote.
