Proof 01
We start with the glass that needs changing
The useful brief is not a new-window sales pitch. It is whether a suitable existing frame can take a made-to-measure sealed unit with the blind already inside.
- Customer question
- You want the built-in blind result without treating the whole window or door set as the default starting point.
- Proof you can check
- The route is replace the glass, not the windows, where the current frame is sound and can accept the required IGU specification.
- Survey confirms
- Survey checks frame condition, bead access, unit size, frame depth, handle clearance and the safe installation route.
