3.EXECUTION

3.1.Fixing to Masonry Cavity Wall – Insulation

Application

Location: To the inner leaf

Fixing

Construct the inner leaf to at least an appropriate level to allow installation of Kingspan Kooltherm® K8 Cavity Board to proceed.

Remove excess mortar and mortar droppings from exposed edges of any installed insulation boards.

Offer the Kingspan Kooltherm® K8 Cavity Board to the external face of the internal leaf and secure in place using the wall ties and retaining disc / clip.

Ensure wall ties include a retaining disc / clip and be of the double drip type, installed drip downward.

The outer leaf is then built up to the level of the top of the boards and the process is repeated.

Ensure that a residual cavity of at least 40 mm is maintained in accordance with the moisture penetration provisions set out in the masonry structures standard AS 3700 as called up in the NCC B1.4.

Cutting

General: Cutting should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side. Ensure accurate trimming to achieve close-butting joints and continuity of insulation.
