Do you know what is the 3 most common mistakes that Architects, Contractor, Installer and other Professional make in glass hardware selection installation?
- Wrong application of glass hardware and fittings.
- Wrong glass sizes apply on glass hardware and fittings.
- Improper surface or structure for mounting glass hardware and etc.
Please refer to the following information for your references:
STANDARD HOLE POSITION FOR TEMPERED GLASS
For glass thickness 6mm and below, w = minimum 1.5 time of the glass thickness.
Example:
for the glass with 5mm thickness, w = minimum 7.5mm.
For glass thickness above 6mm, w = minimum 2.0 time of the glass thickness.
Example:
for the glass with 10mm thickness, w = minimum 20mm.
* Remark:
If W less than 1.5 time of glass thickness, the hole linked to the glass edge must be sawn.
STANDARD HOLE DIAMETER FOR TEMPERED GLASS
The minimum hole diameter must be 5mm or equal to glass thickness.
Example:
for the glass with 10mm thickness, the minimum hole diameter is 10mm
The maximum hole diameter must not more than minimum 1/3 of the glass width/glass height.
Example:
for the glass width/glass height 300mm, the maximum hole diameter must not more than 100mm.
STANDARD RECTANGULAR/SQUARE HOLE FOR TEMPERED GLASS
The minimum distance of rectangular/square holes between glass edges equal to 1/2 of the rectangular/square hole width (w) & height (h).
Example:
The maximum width (w) / maximum height (h) of the rectangular/square hole must not more than 1/3 of the glass width (W) / glass height (H).
Example:
STANDARD NOTCHES DEMENSION FOR TEMPERED GLASS
The height (Y1) of a notch must not more than its width (X1 and X2), (X1≥Y1, X2≥Y1).
The distance (b) between two notches must be at least half the width of the largest notch (X1),
(b≥X1/2).
The distance (a) between the notch and the edge of the glass must be at least half the width of the notch (a≥X1/2).
The radius (R) of the notch must be more than or equal to the glass thickness.
The width (X and Y) of the notch must no more than 1/3 the width (W)/height (H) of the sheet of glass (X≤W/3, Y≤H/3).

Approximate Weight of Architectural Flat Glass
Design professionals, wall system manufacturers, and construction managers often need the weight of materials for engineering and construction site considerations. The table below provides approximate weights of architectural flat glass by thickness.
| GLASS THICKNESS (MM) | WEIGHT (KG/m²) | weight (kg/ft²) |
|---|---|---|
| 3 | 7.5 | 0.696 |
| 4 | 10 | 0.928 |
| 5 | 12.5 | 1.16 |
| 6 | 15 | 1.392 |
| 8 | 20 | 1.856 |
| 10 | 25 | 2.32 |
| 12 | 30 | 2.784 |
| 15 | 37.5 | 3.48 |
| 19 | 47.5 | 4.408 |
| 25 | 62.5 | 5.8 |
Example:
For 12mm glass thickness, width 0.9meter and height 2.1meter.
Glass weight = 0.9 × 2.1 × 30 kg/m²
= 56.7 kg
For 12mm glass thickness, width 3ft and height 7ft.
Glass weight = 3 × 7 × 2.784 kg/ft²
= 58.4 kg
*Remark:
|
• 1 Ft = 304.8 mm |
|
• 1/8 inch = 3.175 mm |
|
* Approximate weights do not apply to patterned glass or products incorporating multiple lites of glass fabricated into an assembled product.
* The guidance given above is indicative and the final manufacturing confirmation should be sought from the supplying factory.
PRECAUTIONS FOR USE OF GLASS IN BUILDINGS
GENERAL
- All door sizes, transoms, jambs, heads, locks, and any other special requirements must be detailed and all types of hardware must be selected before tempered glass is ordered, as its size can not be altered.
- To protect human beings from injury, any facades more than 10° inclination should have laminated glass. In case of fall, the laminated glass will not break and if it breaks, it will break safely.
- When using normal / tinted glass, a check should be made that there is no variation in colours among various batches of glass as this spoils the visual continuity.
- House hold detergents should not be used as glass cleaning agents.
- Avoid contact of the reflective coating or glass with acids or strong alkalis. Substances such as caustic soda used to clean aluminum framing as it will cause extensive damage to the reflective coating and glass surface.
- The edges of a laminated glass must be grounded and not be exposed to any prolonged contact with moisture. Consideration must be given to the use of weep holes or other alternate glazing procedures to ensure a dry framing cavity.
