Thermal insulation pipe section THERMAFLEX Thermacompact IS10 C-15/6 PWL HI/2606015SC, closed-cell foam

THERMAFLEX Thermacompact IS10 C-15/6 PWL HI is a pre-formed closed-cell foam pipe section designed for thermal insulation of straight pipe runs in heating, plumbing and chilled-water systems. The sleeve provides continuous coverage along the pipe surface to reduce heat loss and limit surface condensation. Its Thermacompact construction and IS10 thickness range are tailored to common residential and commercial HVAC and plumbing installations where ease of installation and reliable thermal performance are required.

Advantages

The closed-cell foam composition offers low thermal conductivity and resistance to moisture absorption, helping maintain system efficiency and preventing degradation from water ingress. The pre-formed sleeve design enables quick and neat installation without the need for additional adhesives or extensive mechanical fixing on standard straight sections. The product’s consistent thickness and surface finish contribute to uniform insulation performance and simplified on-site handling.

Suitable for

• Insulation of hot and cold water pipes in residential and commercial buildings
• Heating circuit pipework in radiators, boilers and heat-distribution systems
• Chilled-water and air-conditioning piping to prevent condensation
• Renovation projects where replacing or upgrading existing insulation is required

Key specifications

• Material: closed-cell thermal insulation foam
• Form: pre-formed pipe section (sleeve) for straight runs
• Series/profile: Thermacompact with C-15/6 wall/profile
• Thickness class: IS10 range for thermal efficiency
• Typical applications: heating, plumbing and chilled-water systems
• Surface: smooth, consistent finish for easy installation

How to use

Select the sleeve diameter that matches the outside diameter of the pipe and position the pre-formed section around the pipe so the joint aligns along the length. For continuous runs, butt adjacent sections together to maintain a closed insulating layer. Secure joints and terminations according to the project requirements; in many installations a compatible adhesive or tape can be used to seal seams and keep sections in place. For bends, branches or valves, use complementary fittings or cut and fit sections to preserve thermal continuity at transitions.

Usage recommendations

Store the insulation in a dry, well-ventilated area away from direct sunlight and sources of high heat. During installation, avoid exposing cut insulation edges to prolonged moisture. Ensure compatibility with system temperatures and fluids, and follow local building codes and HVAC best practices for insulation thickness and fire-safety clearances.
