Getting A Graft On At Grafton

Windows at a new mixed used development on the famous Grafton Street in central London street will work harder to reduce noise and provide energy.

More than 1,000m of ISO Bloco 600 tape and 300m of Bloco One tape from ISO-Chemie has been installed to support the conversion of unused office space in Mayfair to an entertainment venue. The tape will provide long-term protection against wind-blown rain ingress as well as an effective acoustic and thermal seal.

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


Smart foam

The self-adhesive Bloco ONE, which uses ‘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.


 “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.”

Sealed from the inside

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.
