Ancon adds new wall tie to Teplo low energy range

Based on the company’s multi-award winning TeploTie with a conductivity of 0.7W/mK, which virtually eliminates heat loss through thermal bridging in cavity wall construction, the new Teplo-BF basalt fibre wall tie features specially moulded safety ends that improve buildability and enhance mortar bond strength by up to 80%.

The new user-friendly design has exceptional mortar grabbing capability, making Teplo-BF particularly suitable for use with lime and other slow-drying mortars.

The Teplo-BF, like the original TeploTie – which was introduced into the UK and Ireland by Ancon in 2010 and since used on a number of ground-breaking passive house and zerocarbon buildings – is created by the setting of innovative pultruded basalt fibres in a resin matrix. This composite material provides a combination of high strength and outstanding thermal efficiency.

The ultra-low thermal conductivity, twenty times below that of stainless steel, means that Teplo-BF ties are excluded from U-value calculations to BS EN ISO 6946, helping to minimise insulation and wall thickness, a particular benefit in modern low-energy construction applications.

Available in the same wide range of lengths and types as the original TeploTie, the new Teplo-BF wall tie is suitable for cavities up to 450mm wide and buildings up to 18 metres in height, and carries BBA and NHBC technical approvals.

Ancon marketing manager Annabelle Wilson, said: “Following discussions with building contractors, Ancon identified a need for a more user-friendly design, offering a more robust bond that is better suited to the general site environment, and greater versatility in the choice of mortars with which Teplo ties can be used. The new Teplo-BF not only meets these requirements but the new moulded ends make these ties safer for bricklayers to work around too.”

Wilson said this range extension provides the market with three distinct Teplo options – the original TeploTie for new-build applications and resin-fixing into an existing structure during retrofit, the Teplo-L-Tie for surface fixing to an in-situ structural frame, and the Teplo-BF, an improved new-build cavity wall tie with high bond strength even in slow-drying mortars and moulded safety ends. “Ancon’s comprehensive wall tie range includes a low thermal conductivity fixing for almost any masonry construction project,” she said.
