Fixing instructions for Dot and Dab
For bonding Warmline range to a wall use a proprietary gypsum based adhesive.
Please follow the manufacturers instructions. As per manufacturers recommendations apply a continuous ribbon of adhesive around any openings.
Apply 3 vertical rows of adhesive dabs to the walls at 300mm centres. Also ensure that there is a continuous bead at the bottom and top.
After the adhesive has set fix a minimum of 2 insulation anchors through the board into the wall. They must go into the masonry by a minimum of 30mm.
Fixing instructions for mechanical fixing
Fix to the wall treated batons 50mm x 25mm at a maximum of 600mm centres. Also fit horizontal batons at both floor and ceiling level.
Then fit the Warmline board using drywall screws at 150mm centres. Always insure that they penetrate the batons by 25mm.
When installing boards to rafters fix them at right angles to the timbers. To ensure a solid finish bridging pieces are to used inbetween the rafters.
