All about external wall insulation
Why choose EWI?
Did you know that around 33% of heat is lost in a home is through uninsulated solid walls? Reduce heat loss and get a brand new façade for your home.
Benefits of EWI
From reduced noise levels in your home to increasing the value of your property, there's more to external wall insulation than just lowering your energy bill.
How does it work?
Rather than compromising the internal space of your home, EWI is attached to the outside of your home and is made up of insulation board and layers of render.
EWI for landlords
As a landlord, external wall insulation offers various benefits such as increasing the energy efficiency and long-term value of your rental property.
