FAQ – Frequently Asked Questions

The right jacketing depends on the application, environmental conditions and the required level of protection. Important factors include indoor or outdoor use, moisture and weather exposure, UV resistance, mechanical durability, hygiene requirements and ease of installation.

ISOLPAK® offers different multilayer jacketing solutions for technical insulation on pipes, ducts and HVAC systems, allowing the product to be selected according to the specific application.

Multilayer jacketing films can provide an effective alternative to conventional metallic jacketing systems.

ISOLPAK® combines the technical advantages of plastic and aluminium with flexibility, easy installation, durability and reliable protection of the insulation system. This makes it particularly suitable for applications where traditional metal jacketing would require more complex handling and installation.

The jacketing should provide reliable protection while being suitable for the geometry, environment and operating conditions of the insulation system.

ISOLPAK® jacketing systems are designed for technical insulation on pipes, pipelines, ventilation ducts, HVAC systems and technical equipment. Different ISOLPAK® products are available for indoor and outdoor applications and for different technical requirements.

Indoor and outdoor applications have different requirements. Outdoor jacketing must withstand UV exposure, weather, moisture and climatic influences, while indoor applications may place greater emphasis on appearance, hygiene, cleanability or specific technical requirements.

The ISOLPAK® range includes dedicated jacketing solutions for both indoor and outdoor technical insulation applications.

When selecting jacketing for technical insulation, consider:

  • indoor or outdoor application
  • moisture and weather exposure
  • UV resistance
  • mechanical resistance
  • pipe, duct or equipment geometry
  • installation requirements
  • hygiene and cleaning requirements
  • required technical documentation and test reports

ISOLPAK® provides a range of jacketing solutions that can be selected according to these different application requirements.

ISOLPAK is used as a protective outer jacketing for technical insulation systems. Typical applications include insulated piping, ventilation ducts, refrigeration systems, HVAC installations, heating systems and industrial insulation projects where a durable and clean surface finish is required.

Yes. ISOLPAK is designed as an alternative to traditional metal jacketing in many technical insulation applications. Key benefits include low weight, easy cutting, fast installation, flexible handling, a clean surface finish and a memory effect that helps the material return to its original shape after bending or deformation.

ISOLPAK ALU supports sustainability requirements by combining verified environmental documentation with durable protection for technical insulation systems. Its Environmental Product Declaration (EPD) provides transparent life-cycle information, while its long-lasting jacketing surface helps protect the insulation underneath. By keeping insulation protected and functional over time, ISOLPAK ALU can help reduce energy loss caused by damaged or exposed insulation.

ISOLPAK ALU is a semi-rigid insulation jacketing film for indoor and outdoor use which combines the advantages of PVC and aluminum-based surfaces. ISOLPAK CLAD is a self-adhesive jacketing solution that can be used for sealing seams and joints of aluminum-coated insulation systems and for weather-protective applications.

Yes. The ISOLPAK family includes products for indoor applications, such as ISOLPAK ALU INDOOR and ISOLPAK PVC. Indoor jacketing films are typically used for the interior facing of hot and cold insulation systems where a clean, protective and professional surface finish is needed.

ISOLPAK jacketing systems are relevant for technical insulation markets such as HVAC, refrigeration, heating, plumbing, industrial insulation, food processing, pharmaceutical facilities, naval and other environments where insulated pipes, ducts or equipment need protective cladding.

ISOLPAK is normally supplied in standard roll lengths of 25 m.

Fire-performance data depend on the specific product.
ISOLPAK ALU: B1, ASTM E84-12 and LOI 45% O₂ according to ASTM D 2863-77.
