Calculating the cost of an external wall insulation (EWI) system is not as simple a task as you might think; the price not only accounts for the insulation materials but also the installation of the system, labour costs, square meterage (for example, our reinforcement mesh comes in 50m rolls while a bag of EWI-220 Adhesive will cover 3m2 of the wall), the choice of decorative finish and so on. What’s more, not only do the prices of materials vary, but some materials require fixings and some adhesive which will also be included in the price. Therefore, the cost of your EWI system depends entirely on the needs of your project. So, how does one go about calculating the cost of their EWI system?

The information you need for the EWI Materials Calculator
- Choice of Render
You can choose between three options depending on what you are interested in: eco, premium and standard. This relates to the decorative finish you want on your walls.
- Amount of metres squared needed
To calculate the number of metres squared needed, multiply the width by the height of each wall you are going to insulate. Do not subtract windows or doors; this will give you an incorrect result as our calculator considers wastage in the final calculation.
- Choice of insulation material
- Choice of Mechanical Fixings
- Amount of Corner Beads
So, whether you are a homeowner looking to install external wall insulation or apply a fresh new render façade to your home, a solid wall insulation installer looking for an easy-to-install product (at a great price) or an architect looking for a way to vastly improve the thermal efficiency of an old property, you have come to the right place.
