Extruded Polystyrene (XPS) Insulation Board
Product category: Thermal Insulation • Construction Materials • Building Envelope Solutions
1. Product Overview
Extruded Polystyrene (XPS) Insulation Board is a rigid, closed-cell foam insulation material designed to provide excellent thermal insulation, moisture resistance, and compressive strength. It is widely used in residential buildings, commercial projects, industrial facilities, roofs, floors, basements, and foundation systems.
XPS insulation boards are manufactured through an extrusion process that creates a relatively uniform, closed-cell structure. This structure helps reduce heat transfer and limits water absorption compared with many conventional insulation materials.
Dusk Technology BD supplies construction and industrial materials for building projects, contractors, engineers, and procurement teams in Bangladesh.
2. Key Features & Benefits
Excellent Thermal Insulation
Helps reduce heat transfer through roofs, floors, walls, and foundations, supporting indoor comfort and energy efficiency.
Moisture Resistance
Its closed-cell structure provides low water absorption, making it suitable for many damp-prone construction applications.
High Compressive Strength
Available in different strength grades for floor insulation, foundation systems, and other load-bearing insulation applications.
Lightweight & Easy to Install
Can be cut to the required dimensions and installed using compatible adhesives and mechanical fixing systems.

| 80–100 mm | Roofs, floors, basements, and demanding insulation systems |
| Above 100 mm | Specialized or high-performance projects, subject to availability |
Thickness selection should be based on the building design, climate, required thermal resistance, available space, and applicable building codes.
5. Main Applications of XPS Insulation Board
-
Roof insulation: Helps reduce heat gain through flat and selected pitched roof systems.
-
Floor insulation: Used beneath suitable floor slabs and flooring systems.
-
Wall insulation: Installed in compatible external or internal wall assemblies.
-
Basement and foundation insulation: Suitable for many below-grade applications when properly designed and protected.
-
Cold storage facilities: Used in refrigeration rooms, cold rooms, and temperature-controlled buildings.
-
Industrial construction: Supports thermal insulation requirements in selected industrial buildings.
-
Infrastructure projects: May be used in engineered applications such as frost protection and selected road or pavement systems.
6. XPS vs EPS Insulation Board
| Feature | XPS | EPS |
|---|---|---|
| Manufacturing | Extrusion process | Expanded foam beads |
| Cell structure | Relatively uniform closed-cell structure | Expanded bead structure |
| Moisture resistance | Generally low water absorption | Varies by grade; often higher absorption than XPS |
| Compressive strength | Available in high-strength grades | Varies widely by density and grade |
| Thermal performance | Typically low thermal conductivity | Typically low thermal conductivity |
| Typical cost | Often higher | Often more economical |
| Common uses | Floors, foundations, roofs, cold rooms | Walls, roofs, packaging and general insulation |
The best choice depends on moisture exposure, loading, fire requirements, thermal performance, installation method, and total project cost.
7. Installation Guidelines
-
Prepare a clean, dry, and appropriately level substrate.
-
Select the correct board thickness and compressive-strength grade.
-
Cut the boards accurately to minimize gaps and thermal bridging.
-
Use adhesives and fixings compatible with polystyrene insulation.
-
Stagger board joints where specified by the insulation system.
-
Install suitable waterproofing, protective layers, membranes, or finishes as required.
-
Follow the manufacturer’s installation instructions and local building regulations.
Fire safety: XPS is combustible. It must be used with the required protective layers and fire-rated assembly details. Do not leave it exposed where prohibited by the applicable fire code.
