Improved levels of acoustic and energy insulation will be provided following specification of ISO-Chemie’s advanced sealing tape for windows at a new mixed used development in central London.

More than 1,000m of ISO-BLOCO 600 tape and 300m of ISO-BLOCO ONE tape has been installed to support the conversion of unused office space to a high-class entertainment venue at 6 Grafton Street in Mayfair, providing long-term protection against wind-blown rain ingress as well as an effective acoustic and thermal seal.


The self-adhesive ISO-BLOCO ONE, which uses so called ‘smart’ foam technology impregnated with different substances to create a measurable U-Value as low as 0.6w/m2k, can offer excellent thermal insulation and can contribute to acoustic sound reduction by 63dB.


Specified to meet stringent project sealing and quality requirements, the sealant tape is part of a fenestration installation package, which includes Schüco Jansen windows, completed by architectural metalwork engineers, Martec Engineering Ltd.


Andy Swift, sales and operations manager for ISO-Chemie, said: “Developers increasingly want smarter ways to deliver their construction and building projects, which use sustainable technologies. Our tapes support this, delivering measurable airtight, acoustic and thermal sealing properties.


Up to 70% cost savings can be achieved using tapes such ISO-BLOCO 600, which enable specifiers and installers to seal windows from inside the building and avoid the need to use time consuming and costly scaffolding and ladders among other external access systems.


The tapes offer 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 tapes were supplied by JIT Industrial Products, the Motherwell-based independent ISO-Chemie stockist.
