Why the model matters
Roof windows are not interchangeable. The frame, the opening method and the space around the glass differ between manufacturers and between generations of the same window. A blind that fits one will often not fit another, even if the glass looks the same size. So it helps to identify the window before ordering anything.
The good news is that most roof windows carry a label. The rest of this page is a step-by-step guide to finding it.
Step 1: Open the window
Most roof windows have a sash that swings or pivots. Open it to a comfortable angle, which is usually enough to see the edges of the frame. Please take care on a ladder or step, and ask someone to hold it steady. Staying inside rather than going out on the roof is the safest way.
Step 2: Find the label
The identification plate is usually a small sticker or metal plate on the frame. Look in these places:
- On the inside edge of the sash, often along the top or one side.
- On the frame, where it is hidden when the window is shut.
- Behind the control bar if there is one.
- On the lining around the inside of the opening, sometimes near the top.
It can be small, scuffed or painted over. A torch and a phone camera help, as you can zoom in on a photo to read it.
Step 3: Write down what the label says
Labels vary, but they commonly include:
- The manufacturer's name or logo.
- A model or type code, a mix of letters and numbers.
- A size code, which may be letters and numbers or a pair of measurements.
- A production date or batch code.
It helps to copy the code exactly, including any spaces or dashes. If there are letters you cannot read, a gap is fine, and a photo is a great help.
Step 4: Measure the glass and frame
Even with a label, a few measurements help us cross-check. Note:
- The overall width and height of the sash.
- The width and height of the visible glass.
- The depth of the frame, if you can see it.
These are a helpful cross-check alongside a proper measure.
Step 5: Take photos
Photos solve most questions. Send us or have ready:
- A wide shot of the window from inside the room.
- A close-up of the label.
- The window open, showing the hinge or pivot.
- The control handle or bar.
- Any existing blind or fitting, with brackets visible.
What if there is no label?
It happens. Labels fade, get painted over or are fitted somewhere you cannot see. If you cannot find one:
- Check any paperwork from the house purchase or building work.
- Look at other roof windows in the house, as they may match and be labelled.
- Take photos of the frame, hinge type and handle. These often point to a window family.
- Let us look at it in person at a free measure.
We like to be certain. If we cannot confirm what the window is, we'll tell you and talk through what can be done.
Opening types you might notice
These are descriptions, not model names, and they help when you are explaining the window to us.
- Centre-pivot. The sash turns around a point in the middle of its sides.
- Top-hung. The sash hinges at the top and swings outward.
- Fixed. It does not open at all.
- Flat roof lights. Often domed or glazed units over a flat roof.
What kind of blinds go on roof windows?
Blinds for roof windows are usually fitted into or onto the frame and are made for that window. They can run in side guides so they stay in place at an angle. Whether the options are manual or motorised depends on the window and the range. See roof blinds and motorised blinds. We write more about this in awkward window measuring and about heat and light in bedroom light control, since lofts are often bedrooms.
Which models we can supply for depends on identifying yours first, so please tell us what you have and we'll happily confirm what suits.
