Xtratherm 24.5mm XT/TL Thermal Liner Dot and Dab (15mm + 9.5mm)

24.5mm Xtratherm XT/TL Thermal Liner Dot and Dab Insulated Plasterboard is a high performance rigid insulation board made from 15mm Xtratherm PIR core faced with composite kraft paper bonded to tapered edge 9.5mm plasterboard, specially designed for internal walls dry lining and insulation, due to its closed cell composition and tight facings that provide not only thermal insulation but also high level of moisture resistance and a vapour control layer. The board also provides a level of fire resistance due to the continuous adhesive ribbons, especially around openings, such as those around windows and doors. The product offers environmental protection, since produced with no harmful gasses, with 0 ODP and less than five GWP. It has very broad application in both new and existing masonry and solid walls and ceilings, regardless of the material, including the insulation of concrete blocks, clay bricks or stone blocks. Maximum installation height for this system is 3m.

Installation

• The boards must be stored in clean conditions and properly covered
• Align the XT/TL Thermal Liner squarely on wall
• Allow a 15mm expansion joint at the top and bottom of the panel, and fill with foam filler
• Mark the position of the panel on the wall
• Apply adhesive dabs to the wall; Vertical dabs @ 300mm centres 25mm in from edge
• Dabs 50-75mm wide approx 25mm deep to allow for tamping. Total contact with boards area should be 20%
• Ensure a 50mm continuous ribbon top and bottom and around any openings to provide firestops, and to achieve predicted U-value and airtightness performance
• Lift the XT/TL Thermal Liner into position using wedges on the floor. Apply pressure to the board to level and embed in the adhesive
• Insulation should be cut back to accommodate an adjoining panel at external corners
• When the adhesive has dried, 3 mechanical fixings (thermally broken) should be fixed through the centre of the board. Setting out and planning is essential
