If you’re considering External Wall Insulation (EWI), one of the first questions you may have is: What does the process actually involve? Good news – it’s far less disruptive than many people imagine and can deliver transformative results in just a matter of days.
Here’s what you need to know about how EWI is installed, how long it takes, and what to expect from start to finish.
Step 1: Scaffolding and Preparation
Because EWI is applied to the exterior of the building, scaffolding is usually required. This gives installers safe access to all external walls and ensures a high-quality finish. Any necessary repairs to the existing wall surface are completed at this stage to create a sound base for insulation.
⏱️ Typical installation takes around a week, depending on the size of the property and weather conditions.
Step 2: External Insulation Application
Once the prep work is complete, insulation boards are fixed to the outside of the building. These boards form a continuous thermal layer that dramatically improves heat retention. The system is then reinforced with a mesh and finished with a high-performance render.
The best part? Because all the work happens outside, there’s minimal disruption to your day-to-day life, and no loss of internal living space – unlike many other insulation upgrades.
