Prefabrication & off-site services
Pre-assembled fixing systems ready for installation that reduce on-site labour, minimise waste and improve planning.
Prevent condensation, thermal bridging and premature corrosion in insulated pipe installations. The Walraven BISOFIX® range provides insulating pipe supports for heating, cooling, HVAC and utility pipework, helping maintain thermal performance at every fixing point. Whether you’re working with elastomeric or PIR insulation, Walraven BISOFIX® offers solutions that combine performance with reliable pipe support.

Have a look at some quick FAQs to help you decide
If your installation uses PIR rigid foam insulation, Walraven BISOFIX® PIR is specifically designed for this application. Available in insulation thicknesses from 20 mm to 80 mm, it provides a vapour-tight connection while maintaining the pipe system’s insulation value.
Standard pipe insulation is interrupted at fixing points, creating thermal bridges that can lead to condensation. Walraven BISOFIX® E insulating pipe supports are designed to preserve insulation continuity and create a vapour-proof barrier, helping prevent condensation and corrosion around support points.
Yes. Walraven BISOFIX® 88 combines thermal insulation with rubber-lined clamp surfaces, helping reduce structure-borne noise while supporting insulated pipework. This makes it particularly suitable for HVAC and low-temperature installations.
The Walraven BISOFIX® range includes dedicated solutions for different insulated pipe support types, temperatures and project specifications. Whether you need a support designed for elastomeric insulation, a high-performance PIR solution for thick insulation layers, or an insulated clamp combining thermal and acoustic performance, there is a Walraven BISOFIX® product to match the application. Available in a wide range of pipe diameters and insulation thicknesses, the range simplifies specification while ensuring consistent installation quality.

Helps prevent moisture build-up at fixing points
Maintains insulation performance across the installation
Compatible with multiple clamp systems and environments
Combines insulation performance with reliable pipe support.

Maintaining insulation performance is only part of the challenge. Pipe supports must also provide a reliable mechanical connection that keeps systems secure throughout their service life. Walraven BISOFIX® combines thermal insulation with proven pipe fixing technology, creating support points that help protect both the insulation layer and the pipe installation itself.
Depending on the project requirements, Walraven BISOFIX® solutions can be combined with pipe clamps such as Walraven Bifix® G2, Walraven HD 500 or Walraven 2S , allowing installers to create a complete support solution tailored to the application. This combination of insulated supports and trusted fixing systems helps deliver durable, professional installations for heating, cooling and HVAC pipework, while maintaining both thermal performance and installation reliability.
