Buying your block lock kit
When buying glass blocks you also need to think about how much of the installation kit you will need for your specific build. This is where our kit calculator comes in handy. Just add in the type of glass block you will use, how many high and how many wide and the calculator will tell you what other kit you need to complete the build. The block lock kit calculates using a 5mm internal joint and an 8mm perimeter joint.
Please note Block lock plastic frame kit is only for 80mm thick blocks and cannot be used with fire rated blocks and the calculators measurements are based on a standard sized 190 x 190 mm squared block.
