Roofing is one of the essential activities in the construction industry. The purpose of roofing is to act as a barrier between the outside elements and building contents despite being a commercial or residential space. However, commercial and residential roofing intend to protect the building and people, but the coverage area differentiates them. The commercial area is different from the residential space and may require other engineering and roofing materials to serve the purpose. One of the popular roofing sheets in Chennai is metal roofing, and they are used widely in every sector. The other thing that commercial and residential roofing have in common is roofing insulation.
A roofing system includes underlayment, flashing, decking, roofing material, barriers, and insulation. This insulation decreases noise pollution and improves the energy conservation of the roofing materials. Hence, insulating your roof would be the right option if you want warm, cosy, and quiet roofing. Therefore, in this post, let us see various insulation options for your metal roofing.
Polyisocyanurate (ISO):
Polyisocyanurate (ISO) is the foremost option for your metal roofing, despite commercial or residential roofing. It is also called polyiso, made of closed-cell foam in the form of a rigid insulation board. JSW roofing sheet dealer in Chennai manufactures these insulation boards in the 4″ x 8″ or 4″ x 4″ sizes around 1 mm to 4 mm thickness. These rigid insulations come in different panel sizes with tapered textures. The polyiso is the most commonly used membrane insulated below the roofing membrane to protect the building from various climatic changes.
Extruded Polystyrene (XPS):
Another significant insulation variation for your building is extruded polystyrene (XPS). This insulation type is ideal for the steel roofing sheets and stays intact with the roofing membrane for longer. The extruded polystyrene is made by mixing the blowing agent with the polystyrene beads at an elevated temperature and pressure. These are sent into an extruder to obtain an extruded polystyrene. The obtained polystyrene has exceptional compressive strength and thermal insulation elements which don’t shrink, swell, or absorb the water.
Similarly, extruded polystyrene has high energy consumption because of its enhanced physical and mechanical properties. Hence, their extraordinary properties have found application in construction industries in flooring, walls, roofs, pipelines, and related things.
Expanded Polystyrene (EPS):
Thirdly, the expanded polystyrene is the widely used roofing membrane for the building because they are cost-effective and have high thermal performance. The expanded polystyrene is a lightweight foam plastic insulation in the form of a closed-cell and has high compressive strength, moisture resistance, and dimension stability. The EPS insulation is used in the built-up roofing, single-ply membrane systems, and modified bitumen systems.
Hence, these are the different types of insulation of your building roofs to act as a barrier between you and the various environmental conditions. Thus, approach Crayon Roofings, the best Z purlin manufacturers, for your roofs to stay intact.
