Follow this link for information on our range of windows and choice of obscure glass.
Window frames are available in standard (30 mm) or large outer (50 mm) frame.
 
For measuring windows fixed to exterior skin, measure windows inside and out:
Measuring Width
Example A | Equal Width Inside & Out |
|---|
 | Take width measurement and deduct 10mm e.g. 1200 - 10
Frame width required = 1190 mm | Example B | Wider Outside Width, Smaller Inside |
|---|
 | Take outside measurement and deduct inside measurement, eg 1260 - 1200 = 60 mm
Larger outer required if over 40 mm difference
Frame Size required: 1260 - 10 mm = 1250 with large outer | Example C | Smaller Outside Width, Larger Inside |
|---|
 | This window generally has wooden liners on inside.
Outside measurement 1200 - 10 mm = 1190 mm frame size |
Measuring Height
Example A | Standard Height |
|---|
 | Take outside measurement and deduct 10mm e.g. 1200 - 10
Frame size required = 1190 mm including outside cill @ 30 mm | Example B | High Internal Cill |
|---|
 | Take outside measurement and deduct inside measurement, eg 1200 - 1150 = 50 mm
Larger outer required. If greater than 50 mm difference at bottom, add on will be required
Frame Size required: 1200 - 10 mm = 1190 mm including outside cill @ 30 mm with large outer | Example C | Low External Head |
|---|
| Outside measurement - Inside 1200 - 1120 = 80mm
As you are greater than 40 mm to head, use large outer frame plus additional 30 mm add on to head.
Frame Size = 1190 inc large outer and 30 mm add on to head |
