Application

Suitable for use as a dry lining board laminate with significantly improved thermal insulation, it also has improved fire safety and improved moisture vapour resistance. Consult local building regulations for use in external walls in buildings over 18 m.

Description

GTEC Thermal K Boards provide good thermal performance for both new build and refurbishment projects. An additional vapour control layer reduces the risk of condensation.


Features and benefits:

  • 9.5 mm plasterboard bonded to phenolic foam.
  • Approximately 50% thermal improvement over GTEC EPS.
  • Range of thicknesses between 30 and 70 mm.


Technical characteristics:

  • Fire, acoustic, thermal and duty performance dependent on the whole system. See Siniat Drywall Manual for Siniat system performances.
