Bloco One foam tape from Iso Chemie is being supplied for the new Aire Lofts residential scheme in Leeds. The tape is designed to provide long-term protection against wind-blown rain ingress as well as an effective acoustic and thermal seal.

The apartments are being built as part of the city’s Climate Innovation District.

The self-adhesive 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, offers high performance thermal insulation and according to Iso-Chemie, can contribute to acoustic sound reduction by 63dB.

Specified to meet stringent project sealing and quality requirements, the foam sealant tape is part of an energy efficient window package for the apartments, which have been designed and built by awarding winning Leeds-based developer, CITU.

The installation tapes are designed to be completely weather tight against driving rain up to hurricane force wind speeds, so installers can quickly apply them around the frame during installation.

Bloco One also enables installers to seal windows from inside the building, avoiding the need to use scaffolding and ladders.

Iso Chemie’s Vario SD Complete humidity variable foil will also feature at Aire Lofts to provide ‘rapid and effective’ year-round high-performance sealing of the window connecting joints. The foil can be located in place and repositioned, if necessary, after initial application before the full strength of the adhesive develops and takes effect. Furthermore, the risk of leaks from poor or patchy adhesive application can be avoided while the foil can be plastered over immediately after installation, providing further time saving benefits.

Nick Thompson, technical adviser at ISO-Chemie, said: “As new building regulations come into effect this year, developers are increasingly requiring 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.”
