Ancon TeploTie

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 effect the tie has on the U-value of the wall.

The challenge is to reduce the thermal conductivity of the wall tie whilst continuing to meet the structural performance requirements of multi-storey and wide cavity construction.

The solution

Ancon TeploTie composite wall ties comprise pultruded basalt fibres set in an epoxy resin and are the most thermally efficient wall ties on the market. With a thermal conductivity of only 0.7W/mK, they can be used to reduce insulation thickness and wall footprint. The sand finish provides an excellent mortar key.

Ancon's low thermal conductivity wall ties can be used in insulated cavity walls to meet the Code for Sustainable Homes levels 3 to 6.

U-Value Calculations

It is important to use the actual cross-sectional area and thermal conductivity of the wall tie being used when calculating the U-Value of a wall, rather than allowing a program to apply default values. This can make a considerable difference to the U-Value calculated; default values will generally overestimate the effect of the wall ties.
