Brick ties

Brick ties are employed in walls made of interlocking or LECA insulating blocks to tie the shells of the block to each other. Brick ties are always installed in the bottom joint of the top block layer and in the top and bottom joints immediately surrounding intermediate floors. Ties are installed in horizontal joints with 500 mm intervals in every third joint.

In addition, ties are installed to the jambs of each door and window opening, where one tie is placed in every joint (with 200 mm vertical intervals).

For walls higher than 3.5 m, we recommend using 4 brick ties for every square metre, i.e. with 500 mm intervals in every second joint.

Brick ties are sold in batches of 50.

Polyurethane products

Polyurethane foam can be applied to the thermal layer of horizontal and vertical seams of thermal blocks. The foam glues the blocks together while the work lasts and helps to ensure that there are no gaps in the thermal layer.
