Opening schedule checklist.
Each opening line should state: reference number, width, height, quantity, opening direction, frame finish, glass build-up and whether a screen is required.
Say whether sizes are wall-opening or finished-frame — the difference decides the deduction we apply.
- Reference number per opening
- Width × height, and which measurement basis
- Quantity and opening direction
- Finish, glass build-up, screen requirement
Performance and compliance brief.
State the project location and the performance targets that matter: wind load, water tightness, air permeability, thermal and acoustic ratings, and safety glazing.
We answer with the corresponding configuration and the supporting evidence for that configuration.
