How dimensions become exact cuts
From rough masonry opening to final profile cuts, see the exact math and clearances applied to every frame, sash, and glazing pocket.
Rough structural opening
Perimeter expansion allowance between the masonry brickwork and outer aluminium extrusion to accommodate structural settling and sealant backing.
Outer frame extrusion
Sash profile & daylight
Glazing pocket & glass
Stock bar yield & kerf
| Component | Code | Formula Rule | Cut Angle | Sample Cut |
|---|---|---|---|---|
| Outer frame (top / bottom) | AF-01 | Overall Width | 45° / 45° | 1200 mm |
| Outer frame (left / right) | AF-01 | Overall Height | 45° / 45° | 1200 mm |
| Sash stiles (casement) | AS-01 | (Height – 2×Frame_W) + 2×Overlap | 45° / 45° | 1124 mm |
| Sash rails (casement) | AS-01 | ((Width – 2×Frame_W) / 2) + Overlap | 45° / 45° | 562 mm |
| Glazing bead (horizontal) | GB-01 | Glass Pocket Width | 90° / 90° | 478 mm |
| Double glazed unit (DGU) | GL-06 | Pocket Width – 8mm clearance | Square | 470 × 1032 mm |
Frequently Asked Questions
Answers regarding project persistence, custom profile configuration, cutting optimization, and workshop-ready export formats.
No. All project data is stored locally in your browser's storage. We do not collect, track, or store your fabrication dimensions or profile configurations on any external servers.
Verification Required
Cutting dimensions are calculated based on your inputs. Always verify calculated values against manufacturer specifications before commencing any physical fabrication.
