75mm Kingspan Kooltherm K108 Phenolic Cavity Board (pack of 6)

75mm Kingspan Kooltherm K108 Cavity Board is a premium performance rigid thermoset fibre-free phenolic insulation core faced on both sides with a low emissivity composite foil. It is specifically designed to limit thermal bridging and uncontrolled airleakage via junctions in cavity wall constructions. A minimum 25 mm residual cavity width is recommended between the insulation and the outer leaf for wall heights up to 12 metres. A minimum 50 mm residual cavity width is recommended for wall heights greater than 12 metres and up to and including 25 metres. The NHBC accept a 50 mm residual cavity width for Kingspan Kooltherm K108 Cavity Board in all exposure zones including areas of very severe exposure to wind driven rain (exposure zone 4) where the outer leaf is fair faced masonry with tool flush joints.

• Thermal conductivity of 0.019 W/m.K,
• Clear cavity is maintained resists moisture penetration,
• Meets NHBC technical requirements when used with a 50 mm cavity,
• The low emissivity foil facings significantly increase the thermal resistance of the cavity,
• Unaffected by air infiltration,
• Easy to handle and install,
• Nondeleterious material,
• Resistant to shortterm contact with petrol and with most dilute acids, alkalis and mineral oils,
  
• Resist attack by mould and microbial growth and do not provide any food value to vermin.

• Kooltherm K108 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 600 mm horizontal centres, a minimum of one course of blockwork below the damp proof course, or 150 mm 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 600 mm horizontal centres a minimum of 200 mm below the top surface of the ground floor perimeter insulation upstand,
• Continue constructing the inner leaf up to the next wall tie course (450 mm above the first usually 2 block courses),
• The next course of wall ties is positioned at the usual 900 mm 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 selfadhesive breathable tape, no less than 100 mm 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 wrinklefree manner and should extend no less than 50 mm 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 200 mm 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.
