Insulated panels have been used in roofing applications for decades due to their excellent levels of thermal, structural and fire performance.
Incorporating a metal façade, insulation and waterproofing in a single panel, the products can be used to create a variety of roof types ranging from typical flat or pitched roofs to dynamic curved designs. As there is no need for multiple layers to be assembled, they are quick to install and provide a safe, walkable platform as soon as they are fixed to the supporting steelwork.
The latest generation of insulated cores can achieve thermal conductivities as low as 0.018 W/m.k, allowing the required U-value to be achieved with a thinner and lighter panel. Meanwhile, the factory-engineered jointing simplifies detailing, helping installers to minimise thermal bridging and create a highly airtight envelope with air leakage rates as low as 3m3/hr/m2 at 50Pa.
However, it is when they are employed as part of a full system that these benefits can really be maximised. The beauty of a system-based approach is that the different components are designed to work together, aiding ease of installation and helping to ensure that ‘as-built’ meets the designed levels of performance.
These specialist elements can improve both the energy performance and overall aesthetics of the building.
