ProGuard Exteriors provide advanced sprayed cork insulation solutions that transform the look, feel, and energy performance of your property.
Whether you’re a homeowner, developer, or business owner, spray cork is an eco-friendly alternative to conventional renders and wall coatings.

Spray Cork Insulation
Traditional external wall insulation (EWI) is often chosen by homeowners aiming to lower heating bills, but it can be expensive, disruptive, and prone to issues if poorly installed.
Sprayed cork offers a smarter, more sustainable alternative with clear advantages. Applied directly onto existing surfaces, it preserves the natural look of a property while avoiding costly roofline, gas flue, or window sill extensions. At just 6–8mm thick, SprayCork is lightweight yet highly effective, with jobs typically completed in 5–7 days compared to the four weeks EWI often requires.
SprayCork is also around 35% cheaper, making it the more cost-effective choice. Beyond savings, SprayCork provides superior breathability, helping to reduce damp and condensation, while being far more eco-friendly than polystyrene systems.
Suitable for both external and internal use, it requires no removal of existing render if in good condition. With added environmental benefits and faster installation, SprayCork delivers long-lasting performance and value.

A staggering 35% of heat escapes through the walls of an uninsulated property, resulting in freezing walls and chilly rooms. Many homeowners attempt to combat this issue by cranking up their heating, which can lead to exorbitant costs.
When heating a home with solid walls and no cavity, warm air meets the cold walls, creating condensation. This moisture accumulates from the constant temperature fluctuations, resulting in mould and dampness. Our exterior spray cork insulation effectively addresses this issue…
Our spray cork insulation installation experts are fully insured and accredited, and approved applicators of CorkSol, boasting over 20 years of experience. We design custom residential spray cork packages for homeowners throughout South East England.
Our main objective is to provide a range of external insulation and rendering services tailored to meet the varied needs of our clients…
Eco-Friendly & Sustainable
Cork is a renewable, eco-conscious insulation material harvested from the bark of cork oak trees, making it a responsible environmental choice.
Improved Energy Efficiency
Spray cork offers excellent thermal insulation, reducing heat loss through walls and helping regulate the internal temperature of your home.
Save Money on Heating Bills
Naturally resistant to moisture, damp, and mould, cork helps protect your home from weather damage, UV rays, and other external factors, lowering maintenance costs.
Reduce Noise Pollution
Cork’s natural sound-absorbing properties help reduce external noise, such as traffic and neighbours, creating a quieter living environment.
