Metal roof build up
Metal roof build ups are roof systems that use profiled metal sheets or smooth metal panels within the roof system. Residential homes use metal roof build ups with the metal sheet forming the final, weathering layer.
Some roof build ups use low profile inner metal sheets alongside high profile outer metal sheets, with a vapour control layer and insulation installed in between. In this type of system, the insulation specified will often be mineral wool.
Warm metal roofs are often seen in commercial buildings. In these types of systems, the insulation layer is laid over the profiled metal substrate together with the vapour control layer which is then finished with as weatherproofing finish.
A variety of materials are used for metal roofing including zinc, steel, aluminium and hybrid metal mixtures. These materials are usually finished with a coating that prevents rust and reflects heat if required.
What are the benefits of metal roof build up
• Lightweight and durable
• Can be laid over an existing roof
• Fast installation
• Ideal for low pitch roofs
What are the benefits of DensDeck® Roof Boards for a metal roof build ups?
Metal roofs are robust, can withstand adverse weather conditions and are also extremely durable. DensDeck® Roof Board cover boards are often installed to improve the acoustic performance of metal roof build ups. They also protect the insulation layer from compression and offer moisture resistance that shields the building envelope in case of unexpected leaks.
In an inverted roof system, especially if a higher profile metal sheet is used, roof boards may be installed to help ensure the insulation layer stays in place. They also help improve the acoustic performance of a metal roof build up.

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.
