Pegasus Block Lock Frame Kit

Pegasus BlockLock is a very simple system for building walls with glass blocks. The system consists of the application of PVC reinforcing profile between the glass blocks and joining them using special glue. You will build the walls yourself. Easily, quickly and cleanly!

Kit includes 8 long profiles, 20 short profiles and 3 Adhesives and is suitable to build with 25 Full size 190x80x190mm blocks. Pegasus BlockLock can also be used with other sized Pegasus Range blocks, providing the thickness is 80mm. Different sized blocks will require a different quantity of profiles, get in touch if you have any questions.


Mortar & Grout 5Kg 2 in 1 (White)

A white, 2 in 1 mortar and grout specially designed by SEVES Glass Block for installing and finishing vertical glass structures.

One 5 kg bag is sufficient for 5 blocks as a mortar bed with Rod & Mortar installation and is sufficient for 50 blocks as a face grout with Block Lock Kit installation.


Silicone - White (280ml)

Silicone is used to seal the perimeter joints to ensure wall stays protected, watertight. Silicone also omits the possibility of cracking in the mortar, or glass, providing a ‘live’ joint to allow for minimal expansion and contraction.

One tube of silicone is suitable for 3 linear meters of application.
