Trocellen Class ALU

Trocellen Class ALU – high-quality insulation with aluminium lamination

Trocellen Class ALU is a closed-cell, chemically cross-linked polyethylene foam laminated on both sides with high-quality aluminium foil. This combination combines the classic advantages of PE foam—low thermal conductivity, an integrated vapour barrier and high flexibility—with the additional properties of the aluminium coating, which reflects radiant heat, provides mechanical protection for the material and significantly increases its durability under demanding conditions.

Product description

Trocellen Class ALU is a closed-cell, chemically cross-linked polyethylene foam laminated on both sides with high-quality aluminium foil. This combination brings together the classic advantages of PE foam – low thermal conductivity, an integrated vapour barrier and high flexibility – with the additional properties of the aluminium coating, which reflects radiant heat, provides mechanical protection for the material and significantly increases its durability under demanding conditions.

The closed-cell structure acts as an integrated vapour barrier, preventing both condensation and moisture from penetrating the insulation material. This ensures that the insulation properties are maintained over the long term, whilst minimising the risk of condensation and corrosion damage. With a diffusion resistance of μ ≥ 15,000, Trocellen Class ALU meets the highest standards for moisture protection.

The insulation material also impresses in terms of acoustics: the combination of PE foam and aluminium lamination ensures a noticeable reduction in airborne and structure-borne noise. Particularly in the case of ventilation ducts, pipework or large-scale installations, disruptive noises are reduced and room acoustics are improved.

In terms of fire protection, Trocellen Class ALU meets the Euroclass standards B-s2,d0 (for 3–14 mm) and C-s2,d0 (for 15–24 mm). This means: flame-retardant, no burning droplets, and minimal smoke development. In addition, the material has been awarded the F1 classification for low smoke toxicity in accordance with NF F 16-101. This makes it suitable for safety-critical applications such as public buildings or public transport.

The aluminium foil on both sides serves several functions: it reflects radiant heat, thereby improving the overall insulation effect; it protects the foam from mechanical stress; and it acts as an additional barrier against dust and moisture. This lamination offers a clear advantage, particularly in outdoor applications or heavily used technical areas.

The range of applications is diverse: Trocellen Class ALU is primarily used in the heating, ventilation and air conditioning (HVAC) sector, where it both reduces energy loss and provides sound insulation. Typical applications include pipework, air ducts, roof and façade structures, industrial plants and transport engineering, where additional fire safety standards must be met.

Thanks to its ease of processing, the insulation material can be flexibly cut to size and adapted, whether in sheet form or on rolls. Even with complex geometries, it remains dimensionally stable, elastic and consistently effective.

Delivery form

The material is supplied as standard in trimmed sheet form and can also be produced as a custom-fit cut to individual dimensions on request. Precise machining and short lead times enable easy integration into a wide variety of applications.

The sheets are supplied in film packaging and must be stored in a dry place. Prolonged exposure to direct UV light must be avoided.

Frequently Asked Questions (FAQ)

Q: What is the function of the aluminium laminate in Trocellen Class ALU?

A: The aluminium laminate serves two purposes: it protects the PE foam from mechanical stress and moisture, and it acts as a vapour barrier and a heat-reflective layer. This makes Trocellen Class ALU particularly suitable for applications where acoustic insulation, moisture protection and thermal insulation are all required.

Q: For which applications is Trocellen Class ALU suitable?

A: The material is frequently used in ventilation and air conditioning systems, in vehicle construction (underbodies, door panels), in caravans and boats, and in industrial insulation. The long rolls enable efficient installation over long distances.

Q: What thicknesses and lengths are available?

A: Trocellen Class ALU is available in thicknesses of 3 mm as roll stock in lengths of 50,000 mm and widths of 1,500 mm. Other variants and cut-to-size sheets are available on request.

Q: Can Trocellen Class ALU be cut to size?

A: Yes. The material is available in rolls and can be cut to size according to your specifications on request. For projects involving large quantities, we recommend making a direct enquiry for volume discounts.
