Hemsec Carrier

An external fire-resistant panel, which accommodates a range of external cladding options.

Features and benefits:

  • A suitable solution for structural, low-air permeability and thermal ‘support’ for roofs or walls.
  • Enhances the energy performance of the building and reduces CO2 emissions.
  • A superior, smooth surface over long panel lengths, which can take external finishes such as zinc, aluminium, standing seams, single-ply membranes and rainscreens.
  • Full thickness range from 80 mm (U-value of 0.25 W/m²K.) to 200 mm (U-value of 0.10 W/m²K.).
  • CE marked, Loss Prevention Certification Board (LPCB) and Factory Mutual (FM Approval).

25-year panel performance guarantee. This is subject to project specific information. Consult the manufacturer for further details.
