Installing Kooltherm

It is recommended when joining two boards together to tightly butt and tape the joins of Kooltherm boards with 48mm wide aluminium foil tape. When taping the boards, a plastic squeegee or blade is recommended to apply applicable pressure to the tape and secure it.

Surfaces should be free from dust, oil, or grease and dry before taping to allow the tape to stick. Cutting should be carried out either by using a fine-toothed saw or a blade. When using a fine-toothed saw, measure, mark and cut the board on an elevated surface to allow the saw to go through the board.

To score with a blade or sharp knife, score the board on one side and snap the board over a straight edge, and then cut along the facing on the other side.

Ensure accurate measurements and trimmings to achieve close-butting joints and continuous insulation.
