This advanced system delivers effective insulation, enhanced moisture control, and improved comfort without compromising aesthetic appeal. Traditional insulation methods often fall short in managing breathability — Cork Spray systems naturally allow moisture to escape, reducing the risk of damp and condensation while improving overall building performance.
SPRAYED THERMAL CORK RENDER

What Is Cork Spray Insulation?

Cork Spray Insulation is a high-quality, sprayed thermal cork render derived from natural cork granules that are bonded and applied directly to internal or external surfaces. This creates a versatile insulation layer that is lightweight, flexible, and capable of improving heat retention and reducing sound transmission.
Leading systems such as Corticyte Thermal Spray Cork Render® and CorkSol advanced cork insulation provide proven performance, long-lasting protection, and adaptability across a range of applications — from solid wall homes to complex commercial structures.
NATURAL PERFORMANCE & VALUE

The Benefits of Cork Spray Insulation

Cork Spray Insulation offers a unique combination of natural performance and long-term value:
Excellent thermal efficiency – Reduces heat loss and improves energy retention
Breathable and moisture-regulating – Helps prevent damp and condensation
Enhanced acoustic performance – Reduces sound transmission through walls
Lightweight, durable coating – Long-lasting protection without structural burden
Eco-friendly and sustainable – Made from renewable cork material
The breathable properties of cork insulation make it especially effective in older, solid wall constructions where moisture management is essential.
EXTERNAL & INTERNAL APPLICATIONS

How Cork Spray Insulation Works

Cork Spray systems combine natural cork granules with advanced binders and coatings to create an insulation layer that:
Conforms to irregular surfaces
Adheres seamlessly without extensive preparation
Maintains breathability while providing thermal resistance
Enhances wall protection from weather and temperature changes
Both external and internal applications can benefit from cork insulation, depending on the property requirements and design needs.
ADAPTABLE & EFFECTIVE

Residential & Commercial Applications

Cork Spray Insulation is adaptable and effective across a wide range of property types:

Residential Homes

Ideal for period properties, solid walls, loft spaces, extensions, and renovation projects where breathability and energy improvement are priorities.

Commercial Properties

Suitable for offices, studios, hospitality environments, and larger buildings seeking sustainable insulation with acoustic and thermal benefits.
Because cork insulation is lightweight and easily applied, it minimises disruption during installation while offering long-term performance.

Cork Spray vs Traditional Insulation

Unlike conventional insulation boards or rigid systems, Cork Spray delivers:
Seamless coverage without joints or gaps
Better moisture control through natural breathability
Superior adhesion even on rough or uneven substrates
Reduced thermal bridging
This makes it especially advantageous for older or heritage buildings where standard insulation systems may be less effective.

Energy Efficiency and Comfort

By insulating with cork, buildings retain heat more effectively, reducing reliance on heating systems and lowering energy costs. The breathable nature of cork also helps regulate interior humidity, improving comfort and reducing the risk of condensation-related damage.
