Ceiling Liner 42.5

When utilizing the roof space for living area or for access to services such as MVHR units and other renewable technologies a warm roof provides the most efficient option. For areas of insulated ceiling when  the roof space is not being used, the addition of Xtratherm Thermal Liner XT/TL below 2 layers for 150mm mineral fibre achieves a U-value of 0.12W/m2K and improves the resultant PSI values at wall and gable junctions.
