Low Conductivity Wall Ties

Wall Ties are an essential element in the strength and stability of cavity walls, but by crossing the cavity they act as a thermal bridge between the internal and external leaves. Generally speaking, the wider the insulated cavity, the more substantial the Wall Tie needs to be and the greater the effect the tie has on the U-value of the wall.

The challenge for the Wall Tie industry, set by the Government’s ambitious energy efficiency targets, is to reduce the thermal conductivity of its products whilst continuing to meet the structural performance requirements of multi-storey and wide cavity construction.

Ancon has met this challenge with a range of low conductivity wall ties.

The range includes the BBA-approved, basalt fibre, Ancon TeploTie which suits cavities from 50mm to 300mm.

TeploTie composite wall ties comprise pultruded basalt fibres set in an epoxy resin. With a thermal conductivity of only 0.7W/mK, they are the most thermally-efficient wall ties on the market.

Ancon stainless steel wall ties have been value-engineered to provide high performance at competitive prices. The effect Ancon’s high tensile wire wall ties have on heat transfer is negligible and they can be excluded from U-value calculations to EN ISO 6946.

CE, UKCA and CE UKNI marking from Leviat

From January 1st 2021, the UK will recognise both the EU CE marking approvals, for a time limited period, and the new UK based approval system, which will be known as the UKCA mark. The EU will only recognise CE marking by EU notified bodies as proof of efficacy moving forwards. Leviat has been working closely with both EU notified and UK approved bodies to ensure compliance is achieved at the earliest possible opportunity and we can confirm that we have obtained all relevant certification.
