Ancon TeploTie, the low thermal conductivity Wall Tie, has been used in the UK’s first retrofit to achieve zero-carbon Level 6 of the Code for Sustainable Homes.
TeploTie wall ties can be resin-fixed into existing walls.
The project involved the refurbishment of architect John Christophers’ own semi-detached home, built in the 1840s with solid brick walls.
The front elevation is internally insulated to preserve the original brickwork. The U-value of the walls is now 0.11W/mK2, 16 times better than before. Almost every thermal bridge was designed out, including all metal fixings.
TeploTie cavity wall ties are manufactured from extruded basalt fibres and have a thermal conductivity of just 0.7Wmk. They are exclusive to Ancon.
There were three key elements to the success of this project; these were creating a super-insulated envelope, achieving high airtightness levels and installing renewable energy systems.
