External Wall Insulation in London
Another home in London, made warmer, smarter and sharper looking. For this project, we installed external wall insulation (EWI) using high-performance EPS boards, finished with a crisp white render. Not only does it give the property a fresh, modern appearance, but it also improves thermal performance, lowers energy bills, reduces draughts and helps protect against damp.
What was once a tired-looking exterior is now clean, energy-efficient and ready to face the British weather for years to come.
