INDUSTRIAL THERMAL INSULATION
A lightweight, closed-cell cross-linked polyethylene foam insulation used to reduce heat transfer and support condensation control across industrial roofs, HVAC ducts, warehouses and metal building structures.
QUICK PRODUCT SUMMARY
XLPE is a cross-linked, closed-cell polyethylene foam used wherever a lightweight, flexible and moisture-resistant insulation material is needed. It is supplied as plain foam or combined with a reflective facing for roofing, HVAC, ducting and general industrial thermal-control applications.
PERFORMANCE ADVANTAGES
XLPE is chosen for projects that need a practical balance of thermal performance, low weight, flexibility and resistance to moisture. Its suitability always depends on the selected grade, thickness, facing and overall installation assembly.
The cellular structure helps limit the movement of moisture through the insulation, supporting dependable use in humid or condensation-prone environments.
The foam layer helps reduce conductive heat transfer through roofs, walls, ducts and equipment when correctly selected and installed.
XLPE adds comparatively little load to roofing systems, ducts and supporting structures, which is useful across industrial applications.
Sheets and rolls can be cut and shaped around roof profiles, ductwork, pipes, equipment and other irregular installation areas.
Correctly selected XLPE insulation can help reduce surface condensation by controlling temperature differences and limiting vapour movement.
Plain foam, aluminium foil and metallised film configurations allow the insulation assembly to be adapted to different project requirements.
APPLICATION AREAS
XLPE can be used across building, roofing and mechanical systems where heat transfer, moisture, surface condensation or limited installation space need to be managed.

Roofing
Metal roofs can transfer significant solar heat into a building. XLPE installed under the roof deck helps reduce conductive heat transfer and can improve internal thermal conditions.

Industrial
Supports heat-control requirements in production areas, workshops and utility zones where internal temperature affects comfort or day-to-day operations.

Logistics
Roof and wall insulation can help reduce daytime heat gain and support more stable internal conditions for workers and stored goods.

Mechanical
Suitable grades of XLPE are used to reduce heat exchange and control condensation around ducts, pipes and mechanical systems, subject to project requirements.
PRODUCT CONFIGURATIONS
The facing and construction should be selected according to the thermal objective, installation environment, vapour-control requirement and exposure conditions.
Used where the closed-cell foam layer is required without an added reflective facing, for selected roofing, ducting and industrial applications.
Includes a reflective facing on one side for assemblies that need an exposed reflective surface or added vapour-control support.
Provides facing on both sides where the insulation needs added protection or reflective surfaces on both faces of the assembly.
A reflective-film configuration used for selected insulation and roofing applications where the specified assembly calls for a lighter facing.
Note: plain foam, aluminium foil and metallised film are not automatically interchangeable — product selection should consider the complete installation assembly.
REFLECTIVE FACING
XLPE foam and aluminium foil play different roles within the insulation assembly. The foam layer primarily resists conductive heat transfer, while the low-emissivity foil surface can help reduce radiant heat transfer when it faces a suitable air space.
PRODUCT SELECTION
The correct thickness cannot be chosen from a general chart alone. It should be based on the building assembly, climate, heat exposure, internal temperature requirement and installation conditions.
PRODUCT COMPARISON
Each insulation type works differently. The right choice depends on the roof assembly, available air space, required insulation performance, installation conditions and project budget.
| Factor | XLPE Foam | Air Bubble Insulation | Hybrid Insulation |
|---|---|---|---|
| Core construction | Closed-cell foam | Enclosed polyethylene bubble layers | XLPE foam combined with reflective bubble construction |
| Primary performance | Conductive thermal resistance | Reflective performance when correctly installed | Combination of foam and reflective mechanisms |
| Profile | Available in multiple thicknesses | Generally lower profile | Product-specific construction |
| Moisture behaviour | Low absorption from closed-cell structure | Moisture-resistant construction | Product-specific |
| Best suited for | Roofing, HVAC, ducts, equipment and industrial applications | Reflective roof assemblies with suitable air space | Projects needing combined insulation characteristics |
| Selection basis | Required thermal resistance, thickness and facing | Air space, facing orientation and roof assembly | Complete project requirement and product design |
No single insulation product is universally best for every application. Selection should be based on the complete system rather than thickness or price alone.
MANUFACTURING AND QUALITY
Product consistency, material selection, facing quality and dimensional control all influence how XLPE insulation performs and installs on site.
Product configuration is matched to the required thickness, density, facing and application conditions.
Thickness, width and roll dimensions are kept consistent for efficient installation and project planning.
Foil or film facing is properly bonded and protected to support handling and installation.
Product inspection, packaging and dispatch controls help reduce installation issues at the project site.
