Window & Door Design
Set frame dimensions and sashes
What this does
Sets the frame size and divides it into sashes and fixed lights. Every cut length, every piece of glass and every hardware set downstream is derived from these numbers.
Before you start
- Know whether your figures are the structural opening or the finished frame. The configurator works in frame sizes.
- Agree the clearance your installers expect around the frame, and deduct it consistently.
Steps
-
01
Open the design from the quotation line.
-
02
Enter the overall frame width and height in millimetres.
-
03
Split the frame: add vertical or horizontal divisions to create the panel layout.
-
04
Set each panel's role — fixed light, or an opening sash.
-
05
For each sash, set the opening direction and the handing.
-
06
Save, then Analyze Design.
Why sash sizes are not frame sizes
A sash is never the size of the hole it sits in. The configurator derives it from the frame using the profile's own geometry — its face width and the overlap it needs — which is why changing the profile series changes every sash cut length even though you never touched a dimension.
Important
Frame, glass, steel reinforcement and glazing beads each follow their own rule. Do not assume a millimetre added to the frame adds a millimetre everywhere — read the analysis, which is what the saw will use.
Common mistakes
- Entering the builder's opening as the frame size, so every unit arrives with no room to fit.
- Measuring one opening and applying it to a row that a wet trade has made subtly different.
- Changing dimensions after production has been released. The cutting list has already been issued to the saw.
