METAL ROOF OVER DECK INSULATION
Metal roof decking is a corrugated metal panel that’s used for a roofing application. It’s installed over steel joists or steel beams and provides a durable platform for the installation of roofing materials, insulation, the waterproof membrane of a roof, and lightweight concrete, It is highly recommended to use insulation with the metal roof. Insulation helps improve Building’s energy efficiency, keeping Building warm during the winter and cool during the summer.

Sloping roofs are becoming popular as they go well with Light Gauge Steel Structures and can be used in temporary structures where conventional construction is legally not possible. However, the problem with Sloping steel roofs is that they are highly conductive thermally and can threateningly amplify sounds of raindrops or hail storms. These problems can be addressed by insulating the metal roofs without adding any weight to the structure itself becomes the water barrier.
As far as over deck roof insulation is concerned it needs to address the profiles of the roof (corrugated GI/cement fibre or profiled precoated steel) without adding load to the structure to address the needs of insulation and sound dampening. For this:
- Layer 1 of insulation cut to shape and fixed to fill the roof profiles
- Layer 2 of insulation provides monolithic insulation to suit the design
- Layer 3 consists of two coats of polymerized cement reinforced with fibreglass mesh providing a strong walkable surface.
- Layer 4 consists of a High SRI (Solar Reflectance Index) paint to ensure reflectance of 90% of Solar Heat and thus providing a cool and heat non-absorbing final surface.
