90mm Kingspan Kooltherm K106 Phenolic Cavity Board (pack of 4)

• Excellent thermal conductivity,
• 10mm cavity is maintained resists moisture penetration,
• The watertight, vapour-open polypropylene fleece outer facing protects against moisture penetration,
• Unaffected by air infiltration,
• Easy to handle and install.

• Kooltherm K106 Cavity Board is normally held in position by the wall ties used to tie the two skins of masonry together,
• Wall ties should include a retaining disc of a thickness <10 mm,
• For a solid concrete ground floor the first row of wall ties are installed in the inner leaf at 600mm horizontal centres, a minimum of one course of blockwork below the damp proof course, or 150mm below the top surface of the ground floor perimeter insulation upstand, whichever is the lower,
• For a suspended timber floor the first row of wall ties are installed in the inner leaf at 600mm horizontal centres a minimum of 200mm below the top surface of the ground floor perimeter insulation upstand,
• Continue constructing the inner leaf up to the next wall tie course (450mm above the first usually 2 block courses),
• The next course of wall ties is positioned at the usual 900mm horizontal centres,
• The next course of blockwork is installed to secure the ties,
• The first row of insulation boards should now be installed between the two rows of wall ties, ensuring each insulation board is retained tight against the inner leaf and joints are lightly butted,
• Each board should be secured at a minimum of three points,
• A self adhesive breathable tape, no less than 100mm wide, should be applied to all horizontal and vertical joints, board edges and abutting junction interfaces. The tape should be applied in a smooth and wrinkle free manner and should extend no less than 50mm either side of joints, board edges and abutting junction interfaces. The seal must be maintained at protrusion locations e.g. wall ties,
• The outer leaf is then built up to the level of the top of the boards and the process is repeated,
• When insulating a gable, insulation boards should be continued 200mm beyond the height of the top storey ceiling and a cavity tray installed above the insulation,
• After raising each section of inner leaf, before installation of the insulation board, excess mortar should be removed and mortar droppings cleaned from exposed edges of the installed insulation boards,
• Use of a cavity batten or cavity board to protect board edges and maintain a clear cavity,
• At the completion of each days work, or whenever work is interrupted for extended periods of time, board edges and joints should be protected from inclement weather.
