Compriband (TP600) is a BBA Approved, impregnated, pre-compressed foam sealing tape, for use around the perimeter of windows and doors. It is comprised of open-cell polyurethane soft foam, impregnated with flame-retardant synthetic resin.

In instances where a window or door reveal has a fluctuating/non-straight surface, or large gaps, that can be difficult to treat with traditional approaches (sealant and backer rod). Compriband works amazingly well in these circumstances in that is expands into the gaps in a cavity, therefore creating an effective, air-tight seal.

Compriband is easily applied to the window frame before installation and then slowly expands over a short period of time, to fill all the gaps around the window, or door frame when the window has been installed. Full compression is usually reached within 7 to 10 days.

It’s important to pay attention to the frame and reveal dimensions before selecting which compriband tape to use, to ensure a suitable level of compression. Providing this has been done, the compriband tape will perform and has been tested with driving rain at 600pa (70mph wind).

Can Compriband Tape Be Used For Passive House Projects?

General material performance and energy efficiency expectations in the UK construction sector are continuing to increase and to accommodate these new requirements, one of the latest innovations from Compribands manufacturer, Tremco Illbruck, is their TP652 impregnated foam tape. This clever tape incorporates an additional, smaller foam section, that creates an even greater level of airtightness. When installing the tape, the step must be installed, facing the inside of the reveal, thus creating significantly greater compression from inside, to out, once the tape has fully expanded. We would recommend this product for any window installers, builders, or developers required to meet the demands of Passive Housing standards.

Why Settle For Second Best?

There are, of course, cheaper alternatives on the market, however we would urge caution in trying to save a few £’s in this area of your installation. In some cases, manufacturers have been known to use ‘less dense’ foam in their products and as a result, the weather performance is generally far inferior to Tremco Illbrucks compriband glazing tape. We would also make the point that compriband is BBA approved, whilst at the time of writing, none of its rivals are. The last thing anyone wants following the completion of a window or door installation is internal damage as a result of water ingress and return visits to site. As the old saying goes, ‘buy cheap, buy twice’!

Frequently Asked Questions:

What’s it used for?

  • This multi-functional sealing tape is used to provide an airtight and driving rain-resistant seal to window and door joints.
  • It also has thermal-insulating properties across the entire depth of the perimeter gap.
  • Airtight and thermally insulated, it maintains the energy performance of the window and door without any deterioration around the perimeter.

Where should it be applied?

  • Suitable for new-build and replacement window and door installations.

What are the key benefits?

  • Maintains the energy performance of the window/door.
  • Quick and easy application.
  • Vapour permeable.

What performance standards does compriband tape meet?

  • BBA Certificate N° 96/3309 and, as part of the i3 system, N° 12/4891. The British Board of Agreement (BBA) is a UK body issuing certificates for construction products and systems and providing inspection services in support of their designers and installers.
  • Driving rain resistant to 600 Pa (70mph winds), also providing thermal and acoustic insulation and airtightness in one product.
  • Complies with BS8213-4:2016 CoP for survey and installation of windows and external door sets.
  • Complies with GGF Guide to Good Practice – installation of replacement windows and doors.

What’s the difference between Comproband TP652 and TP600?

  • It differs due to the innovative composite foam step.
  • It has greater interior compression and meets demands in Passive Housing, new building and renovation. Passive house is a rigorous, voluntary standard for energy efficiency in a building, which reduces the building’s ecological footprint. It results in ultra-low energy buildings that require little energy for space heating or cooling.
  • TP652 meets the requirement “tighter inside than out“ in relation to water vapour diffusion.
