Description
GTEC Thermal PIR Boards are suitable for a wide range of conversion or refurbishment projects that require a significant upgrade in the thermal performance. An additional vapour control layer reduces the risk of condensation.
Features and benefits:
- 12.5 mm plasterboard, bonded to polyisocyanurate foam (PIR).
- 40% thermal improvement over GTEC Thermal EPS Board.
- Range of thicknesses between 37.5 and 82.5 mm.
- The board complies with BS EN 520:2004+A1:2009 type A. Laminate complies with BS EN 13950:2014. The PIR insulation complies with BS EN 13165:2012+A2:2016.
- Fire, acoustic, thermal and duty performance dependent on the whole system. See Siniat Drywall Manual for Siniat system performances.
