TEPLO-BF & TEPLO-BFR Wall Ties

The TEPLO-BF range features polymer end-pieces on both ends of the basalt fibre core, allowing for optimal embedment in both leaves of a cavity wall, even when using weaker mortars such as M2 or moderately hydraulic lime mortar. TEPLO-BFR ties, on the other hand, are designed with a polymer end-piece on one side only and are intended for retrofit applications or bonding into existing structures using chemical anchoring systems. Both types support cavity widths ranging from 75 mm up to 450 mm.

These ties are classified according to PD 6697:2019 as Types 1 through 4, meeting structural performance requirements from light to heavy duty applications. Their mechanical strength has been validated through testing in a range of mortars and substrates, including brick, aerated concrete, and conventional concrete. The ties exhibit excellent tensile and compressive properties, with high resistance to pull-out when resin-bonded in retrofit applications.

One of the most distinctive advantages of the TEPLO-BF and BFR ties is their exceptionally low thermal conductivity—0.71 W/m·K for the basalt fibre core and 0.22 W/m·K for the polymer ends—making them highly effective in reducing thermal bridging. This contributes positively to the overall energy efficiency of the building envelope, aiding compliance with increasingly stringent building regulations and carbon reduction targets.

Designed to withstand harsh environmental conditions, these wall ties have an expected service life of over 60 years, are maintenance-free, and demonstrate excellent resistance to moisture penetration. A continuous helical ridge along the tie provides an integrated drip feature, preventing water transmission across the cavity.

Certified by the British Board of Agrément (BBA) and produced under a ISO 9001:2015 quality management system, TEPLO-BF and BFR Wall Ties offer a modern, thermally efficient, and durable solution for both new-build and retrofit masonry constructions.
