We’re back with another ‘roofing jargon buster’ and here to share our knowledge of another term thrown around by roofing specialists everywhere! In our latest instalment we provide all you need to know about composite panels…
What are Composite Panels?
Composite panels are used in roof refurbishment and made up of three layers in total to provide vital coverage for commercial and industrial roofing systems. The top layer provides the exterior appearance of the roof, whilst the middle layer offers insulating qualities to create a thermal barrier to keep the building warm in the winter and cool in the summer. The final layer is the liner sheet, which can be seen from the inside of the building.
Building Regulations and Composite Panels
The fitting and quality of composite panels are covered by UK building regulations, which are strictly adhered to be JDB to provide all building owners and businesses with a viable roofing solution that will last for years to come. Building regulations state that a composite panel that is 80mm thick offers suitable coverage and an appropriate thermal barrier, a quality which is measured as a ‘U-value’. Sides and cladding of a new build system can be fitted with a composite panel that is 60-70mm thick to ensure it meets building regulation requirements with an acceptable U-value.
In roofing and the wider trade industry, U-value refers to the amount of heat loss within a building, and the higher the U-value, the poorer its thermal efficiency. The U-value also helps to predict the behaviour of a building, information that can be used to select the right materials for its repair or refurbishment.
Types of Composite Panel
Different composite roof panel products are used on a variety of commercial and industrial roofing systems as well as on different areas of the roof itself. If the panels are being fitted as wall cladding, then a standard trapezoidal profiled composite panel is utilised, which can be hung horizontally or vertical to create a finish that suits your taste. Flat insulated panels can incorporate corner and edge details for a stylish alternative to traditional composite panelling. All panels are also available in a range of finishes and colours, as well as in various thicknesses for added thermal efficiency.
