Application

Glass mat faced gypsum roof board used in resilient flat roof assemblies in both new build and refurbishment projects. DensDeck® Prime Roof Board can contribute to the resilience of a flat roof in several ways:

  1. As a cover board installed between the insulation and the waterproofing, it can help to:
  • Protect the insulation.
  • Reduce the stress on the waterproofing.
  • Add rigidity to the entire roof assembly.
  1. As a substrate board installed under the insulation layer, it:
  • Provides a uniform substrate for the vapour control layer.
  • Provides a safer working platform during construction.
  • Can be used in vertical application on parapets (minimum thickness 12.7 mm).
  1. As a recovery board installed over an existing flat roof, it can:
  • Provide a uniform substrate for new insulation and/or waterproofing layers.

Description

CE Marked to EN15283-1:2008+A1:2009. Reaction to Fire: A1 to EN13501-1. Glass mat faced gypsum board with enhanced core technology. For use as cover board, substrate board - including parapet, recovery board.

Features and benefits:

  • Added fire resistance layer.
  • Improved resilience of the insulation layer to foot traffic in construction or during maintenance cycles.
  • Additional support for the waterproofing layer; enhancing resistance to punctures and hail damage.
  • With a relatively low weight the board is easily manoeuvred.
  • The board can be cut with standard drylining tools using ‘score and snap' and does not require gapping.
  • DensDeck® Prime Roof Board does not generally need a primer in bonded or bituminous build ups.
  • When used as a component in a suitable assembly, can help improve airborne sound reduction.
