EWI systems are proven to be the most efficient and effective solid wall insulation method. However, EWI systems typically have the highest upfront costs.
The benefits of EWI go beyond thermal performance, as it can also protect the fabric of your property. EWI systems offer a weather proof coating minimising the risk of weather damage to masonry and timber frames. They are also robust with impressive impact resistance. Due to the additional expense of EWI, most grant schemes allow a more generous contribution for such developments.
EWI systems offer your home a fresh, attractive facade. Coupled with the increased energy efficiency, the development should also add significant value to your home.
