Discover Cork
A material that gives back to the planet. Discover why cork is one of the most extraordinary, climate-positive materials on Earth — and why we love it.
What Is Spray Cork
Spray Cork from CorkSol UK is an innovative and eco-friendly Spray Cork for homes, commercial buildings, offices, and industrial units. If you're looking for the best South West London rendering solution, this is it.
Cork is taken from the cork oak tree, but no trees are felled. Instead, the bark is stripped away, and during the regeneration process, the tree absorbs much more carbon dioxide than usual. This reduces carbon dioxide in the environment, making it a truly sustainable choice.
The product was selected as one of Kevin McCloud's Green Heroes and recently selected as a Green Hero of the Decade.
A material that gives back to the planet
Harvested by hand from the bark of cork oak trees — without ever cutting them down — cork regrows naturally every nine years. It is one of the most renewable, climate-positive materials on Earth.
Cork oak forests, known as montados, are among the most biodiverse ecosystems in Europe. They support hundreds of species of plants, birds and mammals, and their preservation is deeply tied to the cork industry. Every time you choose cork, you're helping protect these vital habitats.
Lightweight, warm, durable and beautifully tactile, it brings a gentle touch of nature into every home. Its unique cellular honeycomb structure makes it naturally insulating, hypoallergenic and incredibly resilient.
That's why we love cork — and why we've built Eco Cork Coatings around it.
Six reasons cork is extraordinary
From forest to your home, cork is a material with remarkable properties that benefit people, properties and the planet alike.
No Trees Are Felled
Cork is harvested by hand from the bark of cork oak trees. The tree is never cut down — only the outer bark is carefully stripped away, leaving the tree alive and healthy.
Regrows Every Nine Years
After harvesting, the bark regenerates naturally over nine years. Each harvest cycle the tree actually absorbs significantly more CO₂ than usual, making it actively climate-positive.
One of Earth's Most Renewable Materials
Unlike quarried or mined materials, cork is a perpetually renewable resource. The same tree can be harvested dozens of times over its 200+ year lifespan.
Zero Waste Production
Every part of the harvested cork is used. Premium grades go to wine corkage, while the excess is used to make Spray Cork. Any remaining material is used in Biomass — nothing goes to landfill.
Beautifully Natural
Lightweight, warm, durable and beautifully tactile, cork brings a gentle touch of nature into every home. Its unique cellular structure makes it unlike any other material on Earth.
Good for People & Planet
Cork naturally repels dust and allergens, making it hypoallergenic. It insulates against heat, cold and noise — creating healthier, more comfortable living spaces while protecting the environment.
Expertise You Can Trust
For centuries the use of cork has been seen in many countries and in many forms. It is a unique raw material with a list of benefits for a wide variety of uses, from thermal and acoustic insulation, to flexibility and durability.
It's unique composition makes it a perfect product for a construction material.
To sum up, a breathable, weather resistant, fire resistant, flexible, insulating render manufactured sustainably from trees that are harvested, not cut down; makes cork coating a perfect choice for just about every surface.
Cork is a fascinating material with excellent acoustic and thermal insulation properties. Its antifungal and resists rotting; it 'breathes', transpiring moisture; it will compress to form a tight gasket (think wine bottles); and it's sustainable, in fact Europe's cork production, in Portugal for example, needs our support.
Now it's been turned into an insulating, breathable, elastic, sustainable render for buildings. Something that's been missing from both the conservation and the eco building markets. Magical.
Benefits of SprayCork

Super adhesive (when it's on, it stays on) on a range of surfaces, including steel
Low maintenance, easy clean coating in 28 standard fade-resistant colours
Excellent natural resistance to sea salt, making it a perfect solution for coastal environments
Highly durable and flexible coating to prevent cracking
Faster application than hand applied render minimizes disruption to your house
Good sound insulator that reduces external noise and vibrations
Patch repairs possible meaning it isn't always neccessary to re-render the entire elevation
Fire resistant (Euro-class B safety rating) and water resistant
Can be used on steel clad buildings, modular constructions and commercial interiors
Our Simple 3-Step Installation Process
Transforming and insulating your home’s exterior is straightforward and efficient. Because our system works with your existing walls, you avoid the heavy disruption of traditional building work. Here is exactly what to expect when you book with Eco Cork Coatings:
Inspection & Preparation
- Careful Inspection: Before application begins, your exterior walls are carefully cleaned and inspected.
- Solid Base: We check your existing paint, render, or coatings for proper adhesion and carry out any necessary minor repairs to ensure a solid base.
- Full Protection: All surrounding surfaces, windows, and fittings are securely masked off to protect your property against overspray.
Specialist Spray Application
- No Demolition: Depending on your wall's current substrate, a base coat is often unnecessary, meaning the treatment can be sprayed straight over the top of your existing finish.
- Expert Installers: Our formally trained and approved installers use specialist equipment to spray-apply at least three layers of premium CorkSol SprayCork directly onto the walls.
- Continuous Barrier: For external projects, this creates a flexible, continuous protective coating with a typical finished thickness of 3-4mm.
Fast Completion & Clean-Up
- Minimal Disruption: Because the vast majority of the work takes place externally, everyday life inside your home continues with minimal disruption.
- Rapid Turnaround: Most residential properties are fully sprayed and completed in just 2 to 3 days.
- End-to-End Service: Your quotation covers the entire project end-to-end—including all preparation, materials, application, and a full final clean-up.
