Breathable and moisture friendly

Spray cork is vapour permeable, allowing moisture to escape rather than becoming trapped within the wall. This makes it a strong option for older and solid wall homes where breathability is essential.

Thermal comfort upgrade

On thermal projects, spray cork can reduce heat loss by up to 35%, helping homes feel warmer in winter and more stable in summer. It is a practical upgrade for under-insulated UK housing stock.

Low maintenance finish

Unlike many traditional finishes, spray cork does not need regular repainting or sealing. In most cases, occasional rinsing with clean water is enough to keep it looking its best.

How Spray Cork Insulation Works

Spray cork insulation is applied as a seamless coating that forms a continuous layer across the surface of the wall. Cork’s natural cellular structure helps slow heat transfer, supporting improved thermal comfort while maintaining breathability.

Because the system is flexible, it can accommodate natural building movement and minor surface imperfections better than brittle finishes. This helps reduce cracking and prolong the life of the façade, particularly on older or exposed properties.

Spray cork insulation can be applied externally to protect and upgrade external walls, or internally where external changes are not suitable. For internal applications, breathable systems such as cork plaster can be used to improve comfort without altering the outside appearance of the building.

Spray Cork Insulation FAQs

These answers cover the most common questions about spray cork insulation, including pricing, suitability for different property types, and what to expect from the installation process.

How much does spray cork insulation cost?

The cost of spray cork insulation varies from project to project and depends on factors such as surface preparation, access requirements, and whether the application is internal or external.

Because every property is different, pricing is usually assessed on a case by case basis following a site review or detailed specification. This ensures the correct preparation, coverage, and finish are allowed for, rather than applying a fixed price that may not reflect the true scope of work.

Can spray cork insulation be applied internally?

Yes. Spray cork insulation can be applied internally when improving the outside of the building is not appropriate. Internal solutions such as cork plaster offer a breathable way to improve comfort without changing the external appearance of the property.

Is spray cork insulation suitable for older homes?

Yes. Older and solid wall properties often rely on breathability to manage moisture. Spray cork insulation is vapour permeable, making it a strong option for traditional buildings when correctly specified and applied.

Will spray cork insulation reduce energy bills?

By reducing heat loss through walls, spray cork insulation can support energy savings of around 12 to 15 percent on thermal projects, depending on the property and usage.

Does spray cork insulation need maintenance?

Maintenance is minimal. In most cases, occasional rinsing with clean water is sufficient. The system is designed to avoid the repainting cycle associated with many traditional finishes.

What are the additional benefits of spray cork insulation?

Spray cork insulation offers benefits beyond thermal performance. Its flexible, breathable structure helps reduce cracking and supports moisture movement within the wall, which is particularly important for older and solid wall properties.

Visually, spray cork can refresh tired or uneven surfaces, creating a clean, uniform finish that improves the overall appearance of external walls without the need for full re-rendering. It is available in a range of colours and textures, allowing homeowners to enhance kerb appeal while upgrading performance.

Spray cork also provides weather protection against wind driven rain, improves resistance to salt air in coastal locations, and helps reduce ongoing maintenance by avoiding the repainting cycle associated with many traditional finishes.
