37.5mm Unilin XT/TL Thermal Liner Dot and Dab (25mm PIR Insulation bonded to 12.5mm Plasterboard)

37.5mm Unilin XT/TL Thermal Liner Dot and Dab Insulated Plasterboard is a high performance rigid insulation board made from 25mm Unilin PIR core faced with composite kraft paper bonded to 12.5mm 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. Unilin XT/TL Thermal Liner Dot and Dab 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.  Unilin XT/TL Thermal Liner 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.
