Fixed
The cheapest and the most airtight. Good where there is nothing to air out.
Made-to-measure joinery
We do the measuring, we cut only once.
Windows, doors and insulating glass made for your opening, with the area and the perimeter worked out from the dimensions on the sheet.
Windows
uPVC and aluminium windows
Made for the opening, with glass you choose.
See the windows
Doors
Entrance and patio doors
With an insulated threshold and security hardware.

Accessories
Roller shutters, insect screens and sills
What gets ordered together with the joinery, so you do not come back twice.

The panels lead to the collections you link to each of them.
How it opens
Choose the opening before the measurement
The opening changes both the price and the way you use the room. A balcony door that opens inwards eats a metre of your wall.
Hinged
It opens wide and is easy to clean on both sides.
Tilt-and-turn
It can be set to air without standing wide open. The usual opening in a flat.
Sliding
It takes up no room inside. Good for the way out to the patio.
Double sash
A full opening, with no mullion in the middle on models with a movable sash.
The diagrams are seen from inside the room.
The glass units
Write the structure exactly as in the manufacturer’s sheet; we add the thickness up.

The usual unit for flats and rooms without much noise.

For windows facing a main road or a school yard.
Ug is for the glass, Uw for the whole window. They are two different figures and we write them separately.
Windows and doors
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.
Which line suits you
The same rows, compared on what matters in a quote.
| The line | Chambers | Glass | Uw, whole window | What for | |
|---|---|---|---|---|---|
| Standard | 5 | Double | 1,3 W/m²K | Replacement in a block of flats | |
| HouseBest seller | 6 | Triple | 0,9 W/m²K | A house you heat yourself | |
| Aluminium | — | Double or triple | 1,5 W/m²K | Large openings |
The figures come from the manufacturers’ sheets; we check them once a year, when the range changes.
What actually matters
Good glass fitted badly is still bad glass
A window is an assembly: frame, glass, spacer and fitting. The figure on the label speaks about only one part of it.
Ug is not Uw
Ug is for the glass, Uw for the whole window. A quote that puts Ug up front and says nothing about Uw is showing you the prettiest figure in the file.
Condensation does not come from the window
Water on the glass in winter means damp air in the room and too little airing. The new window only makes the problem visible.

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.
Cannot find your question? Write to us, we answer the same working day.
