IVAR Alpex Isol disc 20 x 2; 9 mm, 806341950

Product detailed description

This insulated pipe is commonly used in residential and commercial buildings for central heating and potable water distribution. The PEX-AL-PEX construction allows for flexibility and thermal stability, making it suitable for both underfloor heating and radiator systems. Installers typically handle this material during new installations or system upgrades, where thermal efficiency and long-term durability are essential.

Its insulation layer provides additional protection against heat loss and mechanical damage, while the grey polyurethane foam jacket ensures a smooth surface for installation in tight spaces. The white inner polyethylene layer ensures compatibility with potable water standards, and the cross-linked polyethylene (PEX) outer layer offers resistance to thermal expansion and contraction.

The operating temperature of +95°C and nominal pressure rating of PN 10 are critical for determining the suitability of this pipe for central heating and drinking water applications. These values ensure the pipe can handle continuous thermal and hydraulic loads without degradation. The PEX-AL-PEX construction also allows for flexibility in routing and installation, reducing the need for additional fittings.

Installation and connection

The IVAR Alpex Isol disc is typically connected using IVAR.TA or RA series fittings, or with press fittings from the IVAR.PT or PPSU series. Installers should ensure that the insulation jacket is not damaged during cutting or fitting, as this can compromise thermal performance. The pipe is supplied in a 50 m reel, and each segment should be cut cleanly using a suitable pipe cutter. Common installation mistakes include incorrect cutting, which can lead to leaks, and improper fitting torque, which can cause joint failure. Always verify that the insulation layer remains intact and that the pipe is free from kinks or bends that could restrict flow.

Compatibility and accessories

This pipe is specifically designed to work with IVAR.TA, RA, PT, and PPSU fittings. For a complete installation, additional accessories such as valves, manifolds, and insulation tape may be required. Installers should ensure that all fittings and accessories are compatible with PEX-AL-PEX pipe construction and meet the same pressure and temperature ratings. No alternative products are recommended for this application.

Technical background for designers

The PEX-AL-PEX construction combines the flexibility of cross-linked polyethylene with the structural stability of an aluminium layer. This combination allows for efficient heat transfer while maintaining dimensional stability under thermal cycling. The insulation jacket provides an additional layer of protection against mechanical damage and heat loss. The operating principle relies on the pipe's ability to expand and contract with temperature changes without losing integrity. Designers should consider the insulation thickness and material properties when calculating system efficiency and thermal performance.

Service and operation

This pipe requires minimal maintenance due to its durable construction. However, regular visual inspections are recommended to check for signs of insulation wear or damage to the outer jacket. If any damage is found, the affected section should be replaced immediately to prevent further degradation. No specific service intervals are required for this product, but it should be inspected during routine system maintenance.
