Protection cover board for flat roof coverings
DensDeck® Prime Roof Board is a high performance gypsum roof protection board that enhances the performance of commercial roofs. DensDeck® Prime Roof Board is most suited to projects where high performance roofs are essential; such as airports, data centres & biotech.
Roof protection cover boards
DensDeck® Prime Roof Board helps reduce fire risk, improves acoustic performance, provides dimensional stability to the roof system and shields the waterproofing layer / membrane from damage.
Sound reduction
DensDeck® Prime Roof Boards help to block the sound penetrating through a roof assembly into a building. The cover board can be specified in high noise commercial settings, such as airports, to help design the noise out of the building and increase occupant comfort. The cover board can also help to contain the sound within noise polluting buildings, such as factories. This protects surrounding buildings and the environment. Designing roof systems with DensDeck® Prime Roof Boards can achieve better acoustic performance and deliver healthier buildings.
Fire resistance
DensDeck® Prime Roof Boards are designed to offer the roof assembly increased protection from fire and heat spread. When installed as a cover board, it helps protect the roof assembly from external fire sources, such as malfunctioning solar panels or embers from a nearby building. Installed as a substrate / roof board, they help to protect the roof from internal fire spread. The chemical make-up of the DensDeck® Prime Roof Board’s gypsum core contains up to 21% chemically combined water to 79% inert calcium sulphate, which helps slow the spread of fire. Fibreglass mat facers act as the first line of defence.
Weather resistant roof board
DensDeck® Prime Roof Boards are homogenous, flat and strong substrates for installation of adhered, semi adhered and manually fixed roofing waterproofing layers. Increased material compatibility, evenly spread adhesives and enhanced fastener pull increase waterproofing bond strength and the dimensional strength of the roof assembly. As a result, the roof has a greater resistance to wind uplift and the waterproofing is protected from repeated hail strikes and incidental damage by flying debris. DensDeck® Prime Roof Boards act as a barrier that protects the roof insulation & waterproof membrane layer, decreasing risk of water ingress.
Robust working platform
DensDeck® Prime Roof Boards protect the roof assembly during the construction phase and throughout its design life. The cover board has high compressive strength, which increases the load capacity of the roof assembly. This protects the insulation layer from compression as the cover board helps absorb the impact of foot traffic and dead loads of roof installed equipment. The high bond strength between the cover board and the roof waterproofing shields the layer from accidental puncture by dropped tools and damage by sudden impact.
