Reasons to Use Rods & Mortar
- Internal and external panels
- Straight or curved walls
Golden Rules of Installation Using Rods & Mortar
- Glass block walls are self supporting, but not load bearing
- For best integral strength, glass blocks should be installed
into a four sided pre-prepared opening. This opening can
be timber, brick, steel, concrete or blockwork
- Glass blocks expand and contract with temperature change.
- Glass blocks should not be installed when the surrounding
temperature is 5°C and falling or 30°C and rising
- Expansion material must be incorporated to the perimeter
- Openings must be square and perpendicular and made to
suit glass block modules. Glass blocks cannot be cut like
masonry bricks or tiles.
- Maximum panel size without intermediate slip joint is
25m² with no single dimension exceeding 6m in any direction
