Foam sealants specialist ISO Chemie GmbH has gained British Board of Agreement (BBA) product approval certification for its ISO-BLOCO ONE self-adhesive weather tight tape. This confirms its resistance to the passage of wind driven rain, snow, run off water and dust into the interior of a property.
ISO-BLOCO ONE provides a longer lasting seal for window and door joints up to 30mm wide and installation compliance to BS 8213-4:2016. It is impermeable to driving rain at a minimum of 1,000Pa – which ISO Chemie states is 66% higher reliability than most conventional joint sealing tapes.
“BBA certification has reinforced the product’s outstanding weather protection performance, ensuring its suitability for use in passive energy installations,” comments Andy Swift, sales and operations manager – UK and ROI at ISO Chemie GmbH. “As a business we are strongly committed to providing customers with high-quality innovative products, so BBA certification is another significant achievement for us.”
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.
The internal air tight seal has been tested at 1,000Pa pressure difference (20 times more than UK building regulations) and was found to give less than 0.1m³ 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 63dB.
Once installed the tape ensures structures are better protected from elemental factors, such as wind, dust and moisture ingress, by accommodating the changes in structural movement caused by environmental, cyclical and settlement factors. The product also 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.
