Combo signifies the innovative use of two distinct materials to achieve both insulation and waterproofing for a roof simultaneously. This combination is particularly effective in enhancing the durability and energy efficiency of the roofing system.
In the context of Pre-Engineered Buildings (PEB), two common approaches are used for this purpose:
-
Polystyrene with EDM for Dry Construction: In this method, polystyrene insulation is strategically incorporated into the roofing structure. Polystyrene is known for its excellent insulating properties, which help regulate indoor temperatures. Additionally, Enhanced Dry Mix (EDM) concrete is employed to create a solid and waterproof roofing layer. This combination not only ensures insulation against extreme temperatures but also provides effective waterproofing, making it a preferred choice for many PEB applications.
-
Spray Polyurethane with Screeding: Another popular approach involves using spray polyurethane insulation along with a screeding layer. Spray polyurethane offers exceptional thermal insulation properties and forms a seamless, airtight barrier. This is then topped with a screeding layer, which provides both structural support and waterproofing. This method is often chosen for its versatility and effectiveness in reducing energy costs and maintaining comfortable indoor environments in both residential and commercial roofing systems.
Both of these methods have gained popularity due to their ability to reduce indoor temperatures, enhance energy efficiency, and provide robust protection against the elements for homes and commercial roofs. The choice between these approaches often depends on specific project requirements, budget constraints, and regional climate considerations.
