Picture above: Impregnated foam tape technology has been in widespread use in the UK and Europe for twenty years, mainly on commercial new-build projects.

Providing an alternative to the silicone sealants traditionally used by the replacement glazing industry to seal around doors and windows, impregnated foam tapes offer well proven technology coupled with enhanced energy efficiency and ease of use while having the endorsement of glazing industry codes of practice.

Impregnated foam tape technology has been in widespread use in the UK and Europe for twenty years, mainly on commercial new-build projects. A major benefit of these tapes is that they can greatly enhance the energy efficiency of the window as they provide thermal insulation within the joint and also address problems of thermal bridging at the perimeter seal which is an increasing focus of building regulations.

Leaving an uninsulated gap between window frame and wall clearly has the potential for cold bridging. Whether the tape is 20 – 30mm into the joint and backed up by spray applied PU foam or fills the complete joint depth, the resultant thermal benefit prevents the theoretical energy saving performance of the window being compromised by cold bridging. The wider tapes also provide air tightness, further improving thermal efficiency.

Impregnated foam tapes allow installers who are looking to increase the quality of their replacement window installations to differentiate themselves from a basic ‘wet’ sealant finish. The tapes not only provide proven performance and durability but are dry, easy to use and are not weather dependent.

The use of foam tapes is endorsed in two significant and recently revised documents: BS8213-4:2016 Code of Practice for Survey & Installation of Windows & External Doorsets and the GGF Good Practice Guide for the Replacement of Windows & External Doorsets.

illbruck Compriband TP600 is a soft and flexible open cell polyurethane foam joint sealing tape impregnated with an acrylic based and UV stabilised resin that is water repellent and contains a fire retardant. Suitable for use in a wide variety of movement joints and other applications, the tape is weather tight against the most severe combinations of wind and rain and satisfies most expectations as an external weather seal in building and civil engineering applications. With full BBA approval, the product has been extensively tested and has a proven reputation across both the UK and Europe. BBA Certificate N° 96/3309 and, as part of the i3 system, N° 12/4891.
