When glass arrives on site, it is rarely fitted immediately. How you store it during that waiting period can make the difference between perfect glass and expensive breakages.
The biggest mistake: Storing glass flat
The most common (and costly) error is laying glass flat on the floor. Glass is not designed to support weight across its face. A single footstep, dropped tool, or slightly uneven floor can cause it to crack or shatter.
Always store glass upright. When storing multiple panes, stack them face-to-face with cork pads or protective separators between them to prevent scratching.
The correct angle for storage
When leaning glass against a wall, the angle matters. We recommend leaning it at around 5 degrees.
- Too upright → unstable and can tip forward
- Too flat → puts stress on the centre of the pane and can cause bowing or breakage over time
What to rest the glass on
Never rest glass directly on concrete, tiles, or any hard surface. The edges are the most vulnerable part — especially on toughened glass.
Always use timber blocks, rubber matting or high-density foam. This cushions the edges and protects the glass from both impact and moisture.
Does the glass type change how it should be stored?
- Toughened glass: Edges and corners are the weak points — protect them at all costs.
- Laminated glass: Keep edges dry. Moisture can penetrate the interlayer and cause delamination.
- Double glazed units: Store upright and fully supported across the base to protect the seal.
- Coated glass (Ritec, sandblasted, etc.): Leave the protective film on until installation and avoid anything rubbing against the coated face.
How long can glass be stored?
If stored correctly — upright, supported, dry, and protected from impact — glass can be stored indefinitely. However, damp conditions can damage laminated glass and double-glazed units over time.
Tip: Choose a dry, low-traffic area and leave edge protectors on until installation.
