Ancon TeploTie used in First Zero-Carbon Retrofit

Ancon TeploTie wall ties have been used in the UK’s first retrofit to achieve Zero Carbon Level 6 of the Code for Sustainable Homes.

These cavity wall ties are manufactured from extruded basalt fibres and have a thermal conductivity of just 0.7Wm2K. They are ideal for retrofit projects as they can be resin-fixed into existing masonry.

Retrofitting existing housing stock is essential if the UK is to make serious reductions to its carbon emissions. Architect John Christophers is confident the principles employed on this single dwelling could be replicated on a wider scale.

The project involved the refurbishment of the architect’s own semi-detached home, built in the 1840s with solid brick walls. The existing house has reached the same demanding energy efficiency standards as the new extension.

The front elevation is internally insulated to preserve the original brickwork. The U-value of the walls is now 0.11W/m2K, 16 times better than before. Almost every thermal bridge was designed out including all metal fixings. TeploTie basalt-fibre wall ties are exclusive to Ancon and have BBA approval.

The project qualified under the Code for Sustainable Homes as more than half was new-build. The design has been audited by the BRE and verified to Level 6, Zero Carbon status i.e. the net carbon emissions of the building are zero. The project received a RIBA award for Architecture in May 2010.
