Isofoam XPS
Isofoam XPS
Isofoam XPS is a rigid, closed cell extruded polystyrene insulation board engineered for superior thermal resistance and moisture protection.
Property | Description / Value |
Material Base | Extruded Polystyrene (XPS) |
Available Density | 28 kg/m³ to 35 kg/m³ |
Thermal Conductivity | Very Low (approx. 0.030 W/m·K) |
Water Absorption | Negligible (Closed-cell structure) |
Compressive Strength | High (Capable of supporting standard floor/roof finishes) |
Edge Profile | Available in Square or Lapped (Shiplap) edges |
Energy Cost Savings: Significantly reduces heat transfer through walls and roofs, leading to lower HVAC energy bills.
Moisture Resistant: Effectively resists rainwater and humidity, maintaining its R-value over the building's lifespan.
Lightweight & Durable: Easy to transport and install without adding significant dead loads to the structure.
Dimensional Stability: Will not shrink, warp, or sag over time, even with extreme seasonal temperature fluctuations.
Environmentally Friendly: 100% Recyclable and free from ozone-depleting gases (CFC/HCFC-free).
Worksite Efficient: Can be easily cut with manual tools for precise fitting around corners and protrusions.
Roof Insulation: Used in both traditional and inverted roof systems under pavers or gravel.
Cavity Walls: Installed between two layers of masonry to block heat penetration into the interior.
False Ceilings: Used as an additional thermal layer above suspended ceilings for top-floor units.
Basement & Perimeter Walls: Protects the building envelope below grade from thermal fluctuations.
Prefabricated Buildings: Acts as the insulating core for sandwich panels and temporary structures.
Surface Preparation: The substrate must be clean, dry, and free from sharp debris that could puncture the boards.
Laying: Boards should be laid tightly together. In large areas, a staggered (brick-bond) pattern is recommended to minimize thermal gaps.
Fixing: For wall applications, use compatible adhesive mortars or plastic insulation anchors to secure boards before building the outer wall leaf.
Protection: In roofing, cover the Isofoam boards with a separation layer (Geotextile) before applying sand or screed.
