Description

SarnaTherm G is a high density rigid insulation board, faced on both sides with a wet lay coated glass fibre tissue, autohesively bonded to the insulation core during the manufacturing process. The core of SarnaTherm DH is a high-performance CFC-/ HCFC-free rigid urethane insulant with a typical density of 32 kg/m³.

Features and benefits:

  • High compressive strength.
  • Very low thermal conductivity.
  • CFC-/ HCFC-free with zero Ozone Depletion Potential (ODP).
  • Suitable for new construction and refurbishment.
  • No separation layer for membranes is required.
  • Low adhesive consumption.
  • High compression strength.
  • Supports excellent adhesion with appropriate Sarnacol range.
  • Lightweight and low load on the roofing structure.
