Tape seals it at Passivhaus housing association scheme
28th October 2014

Dozens of windows and doors at an award winning Passivhaus new build project have been air tight sealed using advanced foil sealant tape technology from ISO-Chemie.

ISO-CONNECT Vario SD humidity regulating foil has been used to achieve air tightness of less than 0.6 air changes/hour to comply with Passivhaus standards at the new Hastoe Housing Association’s Ditchingham scheme in Norfolk.

Specified by window installer Sidey Ltd UK because of its ability to provide rapid and effective year round high performance sealing of window and door reveals, ISO-CONNECT Vario SD provides ‘intelligent’ humidity control for scheme.

The foil is part of a new generation of window sealing products that not only adapt to seasonal variations, but also provide an excellent external weather seal that surpasses UK Building Regulations for air tightness in domestic and commercial buildings when used as an internal seal, as well as sealing against wind driven rain to Hurricane forces.

The three bedroom terrace houses have been built in a conservation area adjacent to Grade II listed buildings.

Dan Higginbotham, associate at project architects Parsons and Whittley, said: “Vario SD is a very good overall product providing excellent air tightness qualities.

“Cost savings were also achieved using the foil when compared to the sealing product originally considered for the scheme, a vapour resistant plaster sealing tape.”
