The Teplo-BFR is a low thermal conductivity wall tie manufactured from basalt-fibres that 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, or in retrofit applications where a new leaf of masonry and insulated cavity is being constructed against a pre-existing masonry or concrete wall.
Available in 16 standard lengths, Teplo-BFR is suitable for cavities from 75mm to 450mm. The design embedment is 70mm in the inner leaf (resin) and 65mm in the outer leaf (mortar). It is a 7mm diameter wall tie, requiring a 10mm drill bit/hole. FIS VT 380 chemical anchor resin is available from Ancon for use with Teplo-BFR.
Tie Type to PD6697 is dependent on the strength of the substrate and a pull-out test is recommended on site. Ancons test programme indicates Type 1 in 75-150mm cavities, Type 2 in 175-300mm cavities, Type 3 in 325-400mm cavities and Type 4 in 425-450mm cavities.
