Investment in CPD sees ISO Chemie support Passivlux branch opening

  • 28 Jul 2023

Window and door sealant tape specialist ISO Chemie is continuing to invest in supporting its network of UK distributors with a new CPD presentation held at the opening of Passivlux’s latest branch.

The move saw ISO Chemie’s UK sales and operations manager Andy Swift at the window supplier’s Brighton branch, where a new Velfac, Unilux and Solarlux showroom has been opened for trade installers and specifiers across the South of England, who use ISO BLOCO and Hybratec multi-functional joint sealing tapes on installations to protect windows from thermal loss.

Delivered onsite and forming part of CPD training, the well-attended Brighton event covered advice on effective window installation techniques, and how to identify and rectify air leakage.

A large amount of heat is lost from a building through the gap between the windows and the surrounding wall, as thermal imagery clearly shows. This gap is necessary to allow for the natural expansion of the window frame throughout the year, what isn’t necessary, however, is the loss of heat.

Doors and windows account for almost a quarter (21%) of the total air loss of the average house, and adding the joints between walls, floors and ceilings brings the figure up to 50%. Many argue that airflow is desirable, however Andy Swift explained that you can eliminate 50% of heat loss while still retaining some natural air flow.

The statistics illustrate that in most residential properties, heat losses are overwhelmingly replaced by artificial heating rather than through solar energy or internal warmth. This means that reducing heat losses in the home is paramount in the battle to lower energy consumption.

CPD programme

ISO Chemie’s CPD programme is intended to advance knowledge and understanding of airtightness and related issues, enabling specifiers and installers to improve the design and construction of buildings and boost their technical and product expertise.

Andy Swift comments: “Unfortunately, thermal sealing around windows is not specified by law in the UK. That is why ISO Chemie, whose gap-sealing tapes and solutions provide effective resistance against heat loss, is getting the word out there through support for initiatives like this showroom opening.

“The message is clear, not only are the right products needed for the job, but also the right installation. Hence the need to go beyond simple marketing and into the realm of in branch education.

“It’s great to see a company taking installation seriously and ensuring their installations – and not just the windows – have the best thermal and air-tight performance.”

Guidance on the latest airtightness products and sealing solutions was also covered, which includes details of ISO CHEMIE’s range of gap sealing solutions ISO BLOCO, WIN2WALL and BLOCO ONE.  

Up to 70% cost savings can be achieved when using these  tapes for high performance window sealing, rather than the current three component systems. More at
