XPS Foam
XPS (Extruded Polystyrene) foam is a type of insulation material commonly used in roofing and construction applications. It is a closed-cell foam that is known for its high resistance to moisture and its excellent insulation properties.
Extruded Polystyrene (XPS) is a rigid thermoplastic material manufactured from polystyrene. XPS is a high performance, water resistant and lightweight board of thermal insulation.
XPS foam board is often used for above-grade insulation applications such as walls, ceilings, attics and roofs as well as for below-grade applications such as foundations and basements. When used above-grade, it can reduce thermal bridging and improve energy efficiency.
Methods of installation:
-
Direct bonding: involves adhering the foam directly to the roof deck using an adhesive.
-
Mechanically fastened: involves using fasteners to attach the foam to the roof deck.
-
Loose-laid: involves placing the foam on top of the roof deck without any attachment method.
Applications:
- Insulation in walls, roof, and flooring
- Pouring concrete slabs and foundations
- Packaging and cushioning material
- Thermal insulation in refrigeration and cold storage systems
- Heat insulation in hot pipes and ducts
- Moisture barrier in walls and roofing systems
- Insulation for pool and spa covers.
XPS Foam Applications
Construction and Architecture
Insulation specialists use the term, “thermal envelope” or “building envelope” to describe the conditioned space inside a building suitable for humans. The lack of natural airflow in a building creates the need for mechanical ventilation and high humidity, which results in condensation, rotting materials, and microbial growth like mold.
Waterproofing
Bituminous waterproofing systems are designed to protect residential and commercial buildings. Bitumen (asphalt or coal-tar pitch) is a mixed substance made up of organic liquids that are highly sticky, viscous, and waterproof. These systems are sometimes used to construct roofs, in the form of rolls.
