ISO-BLOCO ONE opens window to installation cost savings

The self-adhesive tape enables installers to quickly and effectively seal windows from inside the building during the construction phase. This can avoid the requirement to use time consuming and expensive external access systems, which together with associated health and safety issues, can contribute significantly to a project’s overall costs.

Moreover, because the foam sealant can be applied in the wet and rain, the installation of windows can be undertaken regardless of external weather conditions, avoiding further time consuming and costly delays.

This can add up to potential savings of hundreds of pounds per day, ISO-CHEMIE estimates.

ISO-BLOCO ONE offers a single product ‘fit and forget’ solution for fast and effective sealing based around the European RAL principles of three level sealing - the inside seal area is more airtight than the external one, allowing any trapped moisture inside the joint, or within the wall, to escape outwards rather than into the building.

The external seal area provides weather resistance and breathability, while the intermediate seal area provides extra thermal and acoustic properties and the internal one air tightness and humidity regulation.

ISO-BLOCO ONE provides a longer lasting seal for window and door joints up to 30mm wide and installation compliance to BS8313-4:2016. It is impermeable to driving rain at a minimum of 1,000 Pa – 66% higher reliability than most conventional joint sealing tapes.

The internal air tight seal has been tested at 1000 Pa pressure difference (20 times more than UK Building Regulations) and was found to give less than 0.1 m³ of air loss. At the same time, depending on tape width, it will also supply a U-Value of 0.55 and reduce sound by 63 dB, straight from the box.

Once installed, the tape ensures structures are better protected from elemental factors like wind, dust and moisture ingress by accommodating the changes in structural movement caused by environmental, cyclical and settlement factors. Product complies with energy saving regulations (EnEV) on windows and doors as well as the RAL quality assurance association and can accommodate extremes of temperature changes, from -30°C to + 80°C.
