External Wall Insulation Eurowall Partial
External wall insulation is fitted on outside walls. It is mainly used on solid wall systems, as well as properties constructed with steel or timber frames. It is ideal for buildings where internal insulation is impractical or space is limited.
What is external wall insulation?
This specialised insulation forms a thermal envelope around the building to prevent heat from dissipating through the walls. It typically includes an insulation layer for thermal performance, followed by a reinforced base coat and decorative render for weather protection
What is external wall insulation used for?
Exterior wall insulation is used to:
- Boost energy efficiency in buildings.
- Protect walls from rain penetration and temperature fluctuations.
- Enhance comfort levels in cold or draughty homes.
- Lower heating costs.
- Refurbish old or weathered façades.
- Can improve property value by increasing energy efficiency ratings.
Types of external insulation for house
We offer these external house insulation systems for different wall systems:
Cavity wall insulation
These are used mainly for hybrid wall systems where an external insulation layer is added to enhance existing cavity performance
Rainscreen insulation
These allow insulation behind ventilated cladding. They protect the wall from wind and rain, while ensuring moisture can still escape. Commonly used on commercial buildings and high-rise façades.
Solid wall insulation
This is the most common form of external insulation for solid wall retrofits. It is applied to properties without a cavity wall. It ensures you have a continuous insulation layer over masonry.
Timber frame insulation
This provides continuous external insulation across the entire frame in buildings with structured timber walls.
Each system has its own design, moisture, and structural considerations, so pick one suited to your wall type and site conditions.
Benefits of external wall insulation
Exterior wall insulation has multiple benefits:
- Significant reduction of heat loss.
- Reduced condensation.
- Weather protection for your walls.
- Noise reduction.
- Better-looking facade.
- Lower energy bills.
- Higher property value.

FAQ
How to install external wall insulation?
Before installation, ensure walls are clean, dry, and structurally sound. Installation should be done by qualified professionals.
Secure the insulant to your external walls using adhesives and mechanical fixings. Apply a reinforced base coat with mesh, then finish with a decorative render.
Will external wall insulation stop condensation?
Yes, the insulating material keeps the interior wall warmer, reducing the likelihood of moisture build-up inside the wall. However, you still need sufficient ventilation to manage indoor humidity and prevent mould growth.
Where to buy external wall insulation?
You can buy insulation systems for exterior walls directly from Insulation Wholesale. We stock a full range of EPS, PIR, and mineral wool for external home insulation, plus accessories like fixings, mesh, and render.
How much does external wall insulation cost?
External wall insulation cost depends on the material and wall area. For materials only, prices typically range from £15–£50 per m² (EPS on the lower end, PIR and mineral wool on the higher). When you factor in professional installation costs, you could spend between £80 and £120 per square metre.
