Roof Protection Board
A roof protection board is a thin mechanically strong gypsum core cover board that offers dimensional stability and superior protection to the roof assembly, enhancing its overall performance. The cover board protects both low slope and flat roof build ups from natural forces such as wind, hail, moisture and reduces the potential for mould growth. They also shield the waterproofing layer, such as single ply roof membranes, from sudden impact and protect it from punctures by unexpected objects that could cause water ingress. Glass fibre mat faced cover boards are often specified to overcome challenges of continual compatibility of materials used for roofs which have upstand detailing.
Cover boards act as a defence barrier that prevents damage to the roof membrane caused by mechanical loads of foot and vehicular traffic and the compression of the insulation layer by these loads.
Fire resistant gypsum core cover boards protect the roof build up from external fire whilst gypsum core roof boards help stop the spread of internal fire and heat into roof space.
Specially designed gypsum core cover boards can act as a moisture barrier that protects the insulation layer and the building envelope from moisture ingress during the construction, allowing other trades to start work sooner. The superior moisture protection extends throughout the design life of the roofing system
What is the application of roof protection DensDeck® Roof Board?
DensDeck® Roof Boards are designed to protect roofing assemblies from natural forces such as wind, hail or moisture, as well as adding additional fire resistance. DensDeck® Roof Boards also offer added protection from damage caused by impact and punctures and significantly reduces the effects sound can have on occupier comfort.
Our cover boards help address specific challenges of commercial and industrial structures in a variety of sectors. Buildings in high-noise environments such as airports, structures in critical sectors that need complete protection from moisture such as datacentres, as well as biotech centres benefit from cover boards. Roof system designs that include cover boards are increasingly seen in museums, libraries, and public buildings where the safety and comfort of occupants are paramount.
DensDeck® Roof Boards are light whilst benefitting from high compressive strength. They increase the capacity to accept dynamic loads of foot traffic and dead loads of technology and plant installed on roofs of modern buildings. DensDeck® Roof Boards also add dimensional strength to the roof build up, protecting the insulation layer from compression.

Roof protection boards
The DensDeck® Roof Board helps protect all types of flat roof build ups from natural forces such as hail and wind. They provide dimensional stability to the roof system and shield the waterproofing membrane from dead loads of heavy plant and sudden impact, such as dropped tools or flying debris, whilst adding additional fire resistance.
Sound Reduction
DensDeck® Roof Boards help block the sound penetrating through a roof assembly into a building. Our cover boards help increase occupant acoustic comfort even in high noise commercial settings such as airports.
Fire Resistant
DensDeck® Roof Boards help protect the roof assembly from external fire sources, such as malfunctioning solar panels or embers from a nearby building. They also help to protect the roof space from internal fire spread.
Weather Resistance
DensDeck® Roof Boards enhance fastener pull through, increase membrane bond strength as well as dimensional strength. This means greater resistance to wind uplift and repeated hail strikes.
Roof Access
DensDeck® Roof Boards spread loads and helps protect the insulation layer installed underneath roof build ups. Our cover boards have high compressive strength and add structural strength to the roof assembly, absorbing foot traffic and helping protect from sudden, damaging impacts.
Datacentres
Datacentre construction has a unique set of demands on the building envelope performance. The roof system must be robust and waterproof. Any moisture penetrating through the building envelope could cause service disruption with considerable commercial impact or even damage the expensive equipment. Specification of fibreglass mat face gypsum cover boards is ideal for both new datacentre projects and roof renovations that seek fast project delivery times and exceptional building performance.
Heritage buildings
Conservation and refurbishment of roofs for heritage buildings demands attention to detail. They often use roof coverings made from traditional materials, making installation more time and labour intensive.
Heritage roofs may have areas that are difficult to access, posing a challenge when it comes to the installation and the performance of the roof system. Cover boards are specified to make roof refurbishment easier. They also help increase the building performance of traditional, heritage buildings.
Museums & libraries
Roofing systems for museums and libraries have the important function of protecting valuable collections and creating a safe, comfortable space for the public visiting the facilities. Museums and libraries often combine traditional heritage buildings and striking modern extensions.
This allows architects and designers to blend high performing heritage roof refurbishments with modern green, metal, solar panel roofs, roof terraces with parapet systems or a fusion of the various roof types. Cover boards are a crucial part of these roof build ups capable of enhancing their performance and extending their design life.
Airports
Airports, hangar and maintenance buildings, car parks and other buildings in the aviation sector present their own set of challenges. These projects have intensive schedules and once finished, the highest level of building performance is expected to keep passengers comfortable and safe.
The performance enhancing capabilities of fibreglass mat face gypsum cover boards are ideal for specification in the aviation sector.
Biotech
The construction of biotech centres must overcome a very specific set of challenges. These buildings fall within the critical sector and the expectation is that their roofing systems must be very robust.
Specification of fibreglass mat facer gypsum core cover boards enhances the performance and longevity of roof systems for biotech centres. It can also target improvement in specific areas of building performance, as required by each project.
