Ancon TeploTie, a low thermal conductivity wall tie, has been used in what is claimed to be the UK鈥檚 first retrofit to achieve level six of the Code for Sustainable Homes. The project was eligible for the code as more than half of it was new build. It involved the refurbishment of the architect鈥檚 own semi-detached home, built in the 1840s with solid brick walls. The front elevation is internally insulated to preserve the original brickwork. This delivers a U-value of 0.11W/mK2, 16 times better than before.

The wall ties have been used both in the extension and in the existing building where a new inner leaf was constructed. Here the Teplo Ties were resin-fixed into the existing Victorian brickwork and built into the new blockwork.Teplo Wall ties are manufactured from extruded basalt fibres and have a thermal conductivity 0.7Wm2K.
