The existing 160mm wall cavity of this property needed insulating in order to reduce its U-value in line with more recent regulation changes.
The wall structure had very few wall ties tying the inner block leaf to the outer brick skin. A decision was made to inject WALLTITE® cavity wall insulation in order to provide an airtight insulation layer and stabilise the cavity. Additional bracing was not required and the resulting U-value amounted to 0.15 W/m2k - a drastic improvement for our client!
