Total blocks/packs:

Grout Colour


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.


10mm Spacer (pack 25)

For 80mm thick blocks.

Plastic spacers that vary according to the size of the necessary joint, block thickness and the type of wall (linear or curved): placed between one block and another, they create evenly spaced joints, keeping the framework rod aligned and away from the glass blocks.


Mortar & Grout 25kg 2 in 1 (White)

A white or grey premixed mortar and grout specially designed by Seves for installing and finishing vertical glass structures. Calculator adds white mortar but if you require grey please remove from cart and add from our shop.

Our 25kg Glass Block Mortar is enough to do 25 full size blocks.


Reinforcement Rod - 950mm long (Pack of 10)

For reinforcing the wall, making it more solid and resistant, according to certification regulations.


Expansion Foam (10m)

Expansion strips can be either stapled or nailed along the two sides and head between anchors (no strip necessary on the cill). Expansion foam is only needed if wall is going into a four sided opening to allow for movement of the wall due to temperature change.

Expansion Foam Data Sheet


Glass Block Tie

The Glass Block wall is tied into the frame by use of Glass Block Ties (these become embedded in mortar). Anchors are attached up both jambs (sides) and across the head (top) but not along the cill (bottom). Glass Block Ties are to be placed at each course whilst installing. If the wall is open ended then Glass Block Ties are not required on the open jamb – only thr jamb againt the wall and head (if applicable).
