Ancon Teplotie used in British Passivhaus

Ancon Teplotie low thermal conductivity wall ties manufactured from basalt fibres, have been used in the first certified Passivhaus to be built using traditional masonry cavity walls.

Achieving the energy efficiency levels of Passivhaus relies on the construction of a well-insulated airtight building envelope.

Thermal bridges must be removed wherever possible to limit heat loss.

When building with cavity walls, this makes Wall Tie selection particularly important.

Teplotie wall ties are exclusive to Ancon, and have a thermal conductivity of 0.7W/mK.

They are available in various lengths to suit even the most super-insulated cavities, essentially future-proofing masonry construction with which all clients, contractors and designers are familiar.

The masonry walls on this Passivhaus development comprise an inner leaf of dense concrete block, a 300mm cavity filled with fibreglass insulation batts and a natural stone external leaf.

The build cost of this 118m2 house was just GBP141,000.

Heating costs are expected to be around GBP75 per year.
