Cork-Based External Wall Insulation
Compare Traditional with a Modern Cork EWI Upgrade
There are different approaches to external wall insulation, from traditional rigid board systems to modern cork-based alternatives, each offering distinct benefits in performance and application.
Traditional External Wall Insulation Systems
A traditional external wall insulation system improves thermal performance by fixing rigid insulation boards to the exterior, finished with reinforced basecoat and decorative render.
- Rigid insulation boards mechanically fixed to external walls
- Noticeable increase in wall thickness
- Multi-layer system including mechanical fixings, mesh and render
- Heavier system compared to thin-coat alternatives
- Installation process is more labour-intensive
- May alter window reveals, sills and roofline detailing

With SprayCork EWI System
A professionally installed cork-based external wall insulation system provides thermal improvement while forming a flexible, breathable outer layer that protects the building envelope.
- Helps reduce heat transfer
- Creates a seamless and weather-resistant exterior finish
- Flexible surface designed to accommodate minor movement
- Can help stabilise and cover existing hairline cracks
- Lightweight application with minimal structural impact
- Suitable for brick, block, concrete and existing render
Up to 35% of heat can be lost through uninsulated solid walls, as paint and standard render offer minimal insulation.

What is external wall insulation and how does it work?
External wall insulation adds a layer of insulating material to your property’s exterior, improving thermal performance by helping reduce heat transfer through solid walls. It is finished with a protective render or coating.
How is cork-based insulation different from traditional EWI systems?
Cork-based insulation is a thinner, breathable coating applied directly to external walls that enhances thermal performance, manages moisture and provides weather protection without adding a bulky layer. It is flexible and allows walls to “breathe.”
Can sprayed cork insulation help prevent damp and mould?
Yes. A breathable cork coating helps prevent moisture build-up, reducing condensation and the risk of damp and mould by keeping wall surfaces warmer and allowing vapour to escape.
Can external wall insulation be added to existing render?
Yes. Cork-based systems can often be applied over sound existing render or pebbledash, avoiding the need to remove old finishes first, provided the surface is prepared correctly.
Does cork insulation offer any acoustic benefits?
Yes. Cork’s natural structure can help absorb external noise and reduce sound transmission, providing a degree of sound insulation for busy or built-up areas.
How do I know if external wall insulation is right for my property?
We recommend a free, on-site assessment to evaluate your walls, discuss your goals and explain the benefits and limitations of different systems before you decide. Professional advice ensures you choose the best solution.
