Speedline
With a multi-layer finish of kraft paper/aluminum, this high performance insulation is factory bonded to a board of 12.5mm tapered edge plasterboard and offers a board size of 1.2m x 2.4m. Due to the low thermal conductivity of foam (0.022W/mK), plasterboard provides an optimum thermal insulation solution.
