ISO-BLOCO One tape enables windows and doors to be quickly and easily sealed from inside the building, avoiding the need to use time consuming and costly external access systems like scaffolding and ladders, and provides guaranteed high performance sealing for the lifetime of the window.

Hiring access systems, with the associated health and safety issues, can add significantly to the overall cost of a new build or renovation project, so additional savings can also be made using ISO-BLOCO One.

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

ISO-Chemie estimates that this can lead to potential savings of hundreds of pounds per day.

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.

Quick and easy-to-apply, the self-adhesive ISO-BLOCO One provides a high performance seal for window and door joints up to 30mm wide and is impermeable to driving rain at a minimum of 1,000 Pa – 66% higher reliability than most conventional joint sealing tapes.

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. All three levels are designed to accommodate movement between the adjacent materials.

Once installed, ISO BLOCO One ensures a building is 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.

The internal air tight seal has been tested at 1000 Pa pressure difference (20 times more than UK Building Regulations.) and found to give less than 0.01 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 45 dB, straight from the box.

ISO BLOCO One complies with energy saving regulations (EnEV) on windows and doors as well as the RAL quality assurance association and is able to accommodate extremes of temperature changes, from - 30°C to + 80°C.
