Litagg -Lightweight aggregates

      Litagg   SPM                 SANDFREE  PRE- MIXED MORTAR      Lightweight               Waterproofing                    Insulation  Roof collects significant heat gain/losses due to solar light . In this system a thermal barrier or insulation is provided over the /Overdeck RCC slab , so that the heat gain from the sun is restricted to reach the RCC slab of the roof. In this way we can insulate the roof slab  from getting heated up Conventional Roof Insulation system with high reflective material like china mosaic /  Reflective Coatings / membranes / lightweight concrete like vermiculite / perlite / XPS or any insulation material based on Solar Reflective Index (SRI) values or thermal conductivity values etc. is not an effective method of insulation as the Solar Reflection gets ...
