Cover boards and roof boards have enjoyed popularity in North America and closer to home, in Scotland, for some time. Traditionally, thin timber manufactured boards were installed below the roof covering to increase the roof’s stability and provide a substrate for fixing roof coverings. This helps increase the roof design life and offers additional protection to roof build ups in climates with frequent severe weather.

This white paper will consider the typical mission critical roof build-ups and focus on the key drivers for specification of roof and cover boards. We will examine the various types of roofs and cover boards available on the market today and what their benefits are in terms of risk factor mitigation for mission critical buildings in the following areas:

  • Fire resistance
  • Reduced maintenance requirements and lifetime cost
  • Weather resistance
  • Roof access
  • Moisture resistance
  • Acoustic performance.

The last section of the white paper will contain information on DensDeck Roof Boards, the high-performance mat faced gypsum cover boards by Georgia-Pacific Gypsum (GP), and a shortlist of case studies on recent projects in mission critical sectors.
