Block Lock is an installation method recommended for internal use only. It is ideal for shower screens, panels within partition walls and many interior features within the home. It can only be used for straight walls. Interior designers, property developers and shop fitters are all realising the benefits of the simplicity of construction using the Block Lock system.
Block Lock uses 4mm joints and is a dry fix system. A UPVC profile replicates the mortar joint and is bonded to the blocks using silicon.

Tips for Block Lock Installations
- 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
- Openings must be square and perpendicular and made to suit glass block modules. Glass blocks cannot be cut like masonry bricks or tiles
- A glass block panel should never be freestanding. To secure panel into opening using Block Lock, the process is very simple. All is required is the Block Lock spacer as every row acts as reinforcement
- Maximum panel size recommended when constructing with Block Lock for internal use only up to 10m². (Vertical dimension not to exceed 3m)

Initial Clean & After Care Maintenance
Do not clean with any acidic products, the best product for cleaning is water. Polish each block with a soft cloth using good old elbow grease.
Note: Clean face of block as work proceeds. The glass block installer should have left the glass block wall in a clean, unblemished condition. Requiring only periodical cleaning to maintain an excellent appearance. However, there may be a residue of cement on the glass surface left from mortar/tiling grout identified by whiteish bloom when dry. This may be removed by use of proprietary cement stain remover. (BAL HD Tar Cleaner)
Hydrofluoric Acid or Derivatives Must Not Be Used on Glass Blocks. Paint or cement may be removed by a blade taking care not to scratch the surface of the glass. Periodic cleaning is required using clean water and buffing up with a chamois leather or in clean water use a proprietary glass cleaner and clean off with a lint free cloth.
