Launch of Teplo-BFR Low Thermal Conductivity Wall Tie

Ancon chose the UK’s largest sustainable construction exhibition, Ecobuild, to launch the Teplo-BFR low thermal conductivity wall tie in March 2018.

Teplo wall ties are manufactured from basalt-fibres set in a resin matrix. The Teplo-BFR features a plain end for resin anchoring into an existing structure and a moulded safety end for building into a new bed joint.

It is ideal for new-build cavity wall construction where mortar joints do not align e.g. thin-joint blockwork, and retrofit applications where a new leaf of masonry and insulated cavity are being constructed against a pre-existing masonry or concrete wall.

The innovative composite material of the Teplo range has a thermal conductivity of just 0.7W/mK. Having a thermal conductivity of less than 1.0W/mK means Teplo wall ties are excluded from u-value calculations to BS EN ISO 6946, minimising insulation thickness and wall footprint. They are ideal for zero carbon and other low energy construction, including PassivHaus.

The Teplo-BFR is a 7mm diameter tie, requiring a 10mm drill bit/hole. Available in 16 standard lengths, Teplo-BFR is suitable for cavities from 75mm to 450mm. Suitable chemical anchor resin is available from Ancon, referenced FIS VL 410 C.

The PD6697 Tie Type performance of the Teplo-BFR is dependent on the strength of the substrate, and a pull-out test on site is recommended. Ancon’s comprehensive test programme undertaken in various substrates indicates Type 1 (heavy duty) in 75-150mm cavities; Type 2 (general purpose) in 175-300mm cavities; Type 3 (basic) in 325-400mm cavities; Type 4 (light duty) in 425-450mm cavities.

The Teplo range also includes Teplo-BF and Teplo-L.
