Calculating the cost of a external wall insulation system

Calculating the cost of solid wall insulation is not as simple as you may think. There are a huge number of components in a solid wall insulation system including adhesives, fixings, the insulation boards, as well as the finish required. Therefore, trying to calculate exactly how much materials cost takes some doing, especially when the different materials cover different areas – for example our reinforcement mesh comes in 50m rolls, while a bag of EWI-220 adhesive will cover 3m2 of wall.
