Foam sealants specialist ISO Chemie's ISO-BLOCO ONE self-adhesive weather tight tape for window frames has gained British Board of Agrement (BBA) product approval certification.
The news confirms that the tape, which offers rapid sealing of windows from inside the building during the construction phase,
is able to resist the passage of wind-driven rain, snow, run-off water
and dust into the interior of a property. It also confirms the product's
10-year service life.
ISO BLOCO ONE provides a longer lasting seal for window and door joints up to 30mm wide and installation
compliance to BS8213-4:2016. It is impermeable to driving rain at a
minimum of 1,000 Pa - 66% higher reliability than most conventional
joint sealing tapes.
Andy Swift, ISO Chemie's
sales and operations manager - UK and ROI, said BBA certification,
which is recognised throughout the construction industry as a symbol of
quality and reassurance, reinforced the product's outstanding weather
protection performance, ensuring its ideal for use in passive energy
installations.
He added: "ISO Chemie
is 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 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.
Product comes with a 10-year guarantee and is available from stock on next day delivery service. More at www.iso-chemie.co.uk
