Start with location and risk
A large balcony door, staircase panel, shopfront, skylight, bathroom partition, and office facade do not need the same glass. First note the opening size, height from floor, exposure to impact, wind load, heat, outside noise, privacy, and whether people may lean against the panel.
Common glass choices
- Toughened glass: useful where impact resistance and safer breakage are required.
- Laminated glass: useful for security, overhead areas, railings, and sound reduction.
- Insulated glass units: useful for better heat and sound control in windows and facades.
- Reflective or tinted glass: useful for glare and solar control, but review indoor light levels.
- Acoustic glass: useful near roads, markets, rail lines, airports, and noisy commercial areas.
Ask for performance, not only thickness
Thickness matters, but it is not the only specification. Ask about safety processing, spacer type, coating direction, air gap, acoustic rating, solar heat gain, visible light transmission, edge finish, and compatibility with the selected frame system.
Before final approval
Confirm glass type, thickness, make-up, color, coating, warranty, tolerance, and replacement availability in writing. For large projects, approve a sample in actual daylight before ordering the full quantity.
