Survey
Measure the existing sealed unit
The survey starts with the glass unit already in your window or door, then checks the frame, beads, access and control route before anything is ordered.
- What changes
- The opening is translated into a measured specification for a new integral blind unit.
- What stays
- The suitable existing frame and opening are assessed rather than replacing the whole window.
- Survey check
- Frame condition, bead access, unit size, cavity depth and control clearance.
