Roof Coatings

Cork roof coating is a spray-applied layer made from natural cork granules mixed with resins and water-based binders. The material is applied using a spray gun directly to the roof surface, creating a seamless cork coating that bonds tightly with the substrate. The process forms a waterproof, breathable, and flexible cork layer that utilizes cork’s natural insulation properties.

Sprayed cork roof coatings adhere to various roofing materials, including metal, asphalt, and existing membranes. Because cork is a natural thermal barrier and acoustic insulator, it reduces heat loss while dampening noise from rain, wind, and traffic.

Cork is a natural, renewable building material sourced from cork oak trees without cutting them down. Compared to synthetic options like spray foam or petroleum-based coatings, cork coating products offer longer-lasting insulation and better breathability, which prevents moisture buildup.

Cork spray roof systems outperform tar, rubber, and acrylic coatings in flexibility and temperature regulation. Corkol spray, for example, doesn’t crack under thermal movement. It expands and contracts naturally with the building’s exterior, maintaining integrity across seasons, thanks to the natural insulation properties of cork.

The benefits of sprayed cork extend far beyond aesthetics. A cork roof coating adds a flexible and textured protective layer to the roof, acting as a waterproof and insulative shell. Here’s what cork spray provides:

• Thermal and acoustic insulation: Reduces energy costs and noise pollution.
• Weather resistance: Protects your roof from UV rays, rain, and thermal cycling.
• Eco-friendly: Made from natural cork, a sustainable resource, cork spray is a choice that aligns with your environmental values and contributes to a greener future.
• Anti-slip surface: Cork render improves safety during maintenance on sloped or flat roofs.
• Low maintenance: Cork is naturally resistant to mold, mildew, and cracking, providing you with a worry-free roofing solution that requires minimal upkeep.

These attributes make cork an ideal choice for residential and industrial roof applications, giving you confidence in the performance of your roofing solution.

Cork’s insulation properties come from its ability to resist heat flow and sound vibration. It is an excellent choice when you want to insulate your roof without adding bulky layers. Its natural thermal and acoustic insulation makes it superior to many synthetic insulators.

Cork coatings act as thermal barriers, reducing heat penetration during hot months and preventing heat loss during colder seasons. This dual function lowers HVAC demand and stabilizes internal temperatures.

Due to the thermal cork properties, energy efficiency gains are especially notable in buildings with high surface temperature exposure. A sprayed cork roof coating can reflect solar radiation and provide natural thermal regulation. As a result, buildings coated with thermashield cork spray require less artificial heating and cooling.

Cork insulation helps homeowners and commercial property managers cut energy costs while lowering their carbon footprint by reducing reliance on HVAC systems.

Cork is a renewable resource harvested from cork oak trees every 9–12 years without harming the trees. It’s biodegradable, recyclable, and naturally sourced. Cork products, such as cork sol and thermal cork solutions, rely on clean manufacturing methods with minimal environmental impact and are made from the cork tree.

Unlike spray foam insulation or petroleum-based wall coatings, cork doesn’t release volatile organic compounds (VOCs), making it safe for installers and building occupants. Its breathable nature also prevents condensation, reducing the likelihood of mold.

For anyone looking to build with sustainable roofing materials, using cork is a great way to lower environmental impact while gaining performance.

Yes, cork coatings are versatile and can be used on various structures, including industrial, flat, and conservatory roofs. The natural flexibility and durability of cork make it suitable for a wide range of applications, from large-scale commercial buildings to more delicate residential installations.

Spraycork is especially effective on industrial roof systems exposed to extreme weather, mechanical stress, and thermal shifts. It acts as a flexible insulator and sealant in one layer. On conservatory roofs, cork spray, a choice for cork spray, reduces solar gain, glare, and internal heat buildup.

By applying sprayed cork to metal, bitumen, or EPDM roofs, you achieve waterproofing, acoustic comfort, and long-term protection—all in one coat.

Sprayed cork roof coatings have excellent longevity. Cork, a natural material, is naturally resilient, resistant to UV degradation, and retains its flexibility over time. When applied correctly, a cork spray roof lasts 15–20 years with minimal maintenance.

Unlike conventional coatings that harden and crack with age, cork, as a natural material, maintains elasticity and bonds strongly to the surface. Thermashield cork spray resists peeling, chipping, and bubbling even under harsh sun and heavy rainfall.

Because cork is an excellent insulator and is waterproof, it adds structural protection to your roofing system and shields it from thermal cycling and water ingress.

The application of cork spray coating, derived from the cork tree, is a meticulous process. It involves cleaning and priming the surface to ensure proper adhesion. Technicians then apply 2–3 layers of cork insulation evenly across the roof, typically allowing drying time between coats. This detailed process ensures a high-quality, long-lasting cork roof coating.

Each layer cures into a flexible, breathable membrane that conforms to the roof’s shape. The spray-applied cork coating can be tinted to match desired colors, creating functional and aesthetic improvements.

Installers trained in applying sprayed cork use techniques that guarantee consistent thickness and bonding. Kliu Cork Spray’s certified application process ensures maximum performance for both commercial and residential roofs.

Kliu Cork Spray is a high-performance spray cork system developed for roofing, exterior walls, and building envelope insulation. It utilizes natural cork sourced from cork oak trees and processed into cork granules. The formula includes water-based resins and is VOC-free.

Compared to other products like Corksol SprayCork or Thermalcork Solutions, Kliu Cork Spray offers similar insulation properties but is optimized for sprayability and adhesion across industrial, commercial, and residential surfaces.

Kliu’s system creates a cork material that resists fading, retains flexibility, and performs across climates. The product is ideal for homeowners seeking to protect their roof, commercial buildings aiming to reduce surface temperature, and anyone wanting to use cork as a sustainable insulator made from a natural material.
