EWI Existing Properties

External Wall Insulation

Existing Properties

Benefits:

Existing Properties built with solid walls or for non-traditionally built properties such as concrete Levitt “Cartwright & Wimpey “No Fines”, retaining the properties heat can be extremely costly & prove difficult as the thermal properties of the existing walls allow quick transfer of heat from the internal wall to the external wall. This can increase energy bills and make budgeting through winter difficult. Often the external walls of these properties can degrade a lot quicker due to damp and moisture leading to wider scale structural issues & defects.

The best solution to tackle both the poor thermal performance and increase the weather proofing is to wrap the exterior walls, which is available with a variety of insulation materials and finishes to compliment any suitable property. The most common and cost effective insulation typical used on refurbishment projects is Expanded Polystyrene (EPS) coupled with a polymer enhanced dash or silicone finish. For high rise, premises with multiple occupancy or timber framed properties, the insulation most suitable would be mineral wool due to being non-combustible. Specialist finishes are also available including brick effect render, brick slips and feature details such as header courses & quoins. 

Often missed additional benefits of EWI include, increased acoustic insulation, reduction of future maintenance to external walls and aesthetic improvements giving the building a new lease of life. Due to the improved thermal performance, the building’s Energy Performance Certificate (EPC) can increase dramatically, reducing the energy demand and reducing fuel bills. Furthermore, a property treated with EWI typically increases in value by up to 36%, in some parts on England, based on a case study conducted by government. 

(DECC) Upgrading properties with External Wall Insulation also has wider community benefits such as increasing resident’s pride in their area as well as their homes, which is why External Wall Insulation plays an impressive & remarkable part in area regeneration schemes across the UK. Evidence is getting gathered to unveil that refurbishment of existing housing can be far more cost effective than redevelopment as well as being quicker to tackle the growing housing crisis, bringing unused, unloved 20th Century housing back into the 21st Century.
