ISOLPAK® ALU VS ISOLCLAD®
ISOLPAK® ALU and ISOLCLAD® are both designed to protect technical insulation systems, but they use different material and installation concepts for different application requirements.
| Comparison | ISOLPAK® ALU | ISOLCLAD® formerly ISOLPAK CLAD |
|---|---|---|
| Product concept | Durable jacketing system with mechanical fastening. | Flexible, self-adhesive multilayer cladding solution. |
| Installation | Formed around the insulation and mechanically fastened. | Applied directly to a properly prepared insulation surface. |
| Mechanical protection | High rigidity and mechanical durability. | Flexible protective cladding for a wide range of technical insulation applications. |
| Complex geometries | Well suited to regular surfaces, pipes and prefabricated components. | Particularly suitable for connections, transitions, fittings and complex geometries. |
| Outdoor applications | Designed for durable outdoor jacketing and exposed installations. | Available in solutions designed for indoor and outdoor technical insulation applications. |
| Installation process | Requires measuring, forming and mechanical fastening. | Self-adhesive construction supports fast and efficient installation. |
| Typical applications | Pipes, ducts, tanks, vessels, large diameters and exposed surfaces. | Pipes, ducts, connections, transitions and geometrically complex areas. |
Two protection concepts: ISOLPAK® ALU provides a rigid, mechanically fastened outer jacketing, while ISOLCLAD® provides a flexible, self-adhesive cladding solution. Depending on the system design and application, both technologies can also be used within the same technical insulation system.
ISOLPAK CLAD is now ISOLCLAD®.
The former ISOLPAK CLAD range has been further developed and is now
presented under the dedicated ISOLCLAD® brand.
Which solution should you choose?
Choose ISOLPAK® ALU when mechanical strength, rigid jacketing and durable protection of larger surfaces are the main priorities.
Choose ISOLCLAD® when self-adhesive installation, flexibility and efficient processing around complex details are required.
Combine both technologies when ISOLPAK® ALU provides rigid protection for the main surfaces and ISOLCLAD® is used for joints, transitions, connections or complex geometries.
ISOLCLAD® is the dedicated TTM brand for the self-adhesive cladding solutions formerly known as ISOLPAK CLAD.
