Expanded insulation cork boards

Are traditional insulation materials letting you down during the winter months, allowing cold air and noise to disrupt your home? Consider a smarter alternative: expanded cork panels. Designed for superior efficiency, these panels provide excellent thermal protection during frosty weather and help to dampen external noise. What sets them apart from regular cork? Their exceptional insulating capabilities, both thermal and acoustic. By installing expanded cork panels on your walls, you’re opting for a modern upgrade over traditional cork, and a solution that vastly outperforms polystyrene and mineral wool.

HOW ARE EXPANDED CORK PANELS PRODUCED?

The process begins with the harvest of cork oak bark, which is then ground into granules. These granules are placed in moulds and heated to very high temperatures, causing the cork to expand. It’s a bit like making popcorn – but with cork! As a result, the material turns dark brown and expands, enhancing its insulating properties for both heat and sound. The best part? No artificial chemicals are added, making it a completely natural and environmentally friendly choice.

ARE EXPANDED CORK PANELS EFFECTIVE INSULATORS?

Yes, absolutely! Expanded cork panels act as an exceptional thermal insulator by minimising heat transfer through walls. With millions of tiny air cells within their structure, they efficiently retain heat indoors, helping you save on energy bills during the colder months.

CAN EXPANDED CORK PANELS REDUCE NOISE?

Indeed, they can! Thanks to their porous composition, cork panels absorb sound exceptionally well. Whether you’re dealing with noise from outside or within your home, these panels can help create a quieter, more serene environment.

HOW DO YOU INSTALL EXPANDED CORK PANELS ON WALLS?

Installation is straightforward. Simply use a high-quality cork adhesive, such as Wakol D-3540. For ceiling applications, additional support with plugs or screws is recommended to keep the panels securely in place.

WHERE CAN YOU USE EXPANDED CORK PANELS?

Expanded cork panels are highly versatile and can be used for insulating walls, ceilings, and roofs. They are ideal in situations where traditional cork materials may not suffice.

HOW DO EXPANDED CORK PANELS COMPARE TO OTHER INSULATION MATERIALS?

Expanded cork panels are a brilliant alternative to conventional insulation materials. Unlike mineral wool, which can irritate the skin and absorb moisture (leading to mould growth), cork is natural, hypoallergenic, and resistant to mould.


Compared to polystyrene, cork is more durable and easier to recycle, making it a greener choice for your home.


And when it comes to polyurethane foam, cork offers a safer and simpler option. Polyurethane can release toxic fumes in case of fire, whereas cork remains safe, non-toxic, and user-friendly, even in extreme conditions.

Looking for an eco-friendly way to keep your home warm in winter and cool in summer? Expanded cork panels are an excellent solution. Not only do they provide outstanding insulation, but they also reduce outside noise, helping you create a more peaceful and comfortable living space.


Cork panels also promote a healthier indoor environment by allowing your walls to "breathe." With improved air circulation and minimal maintenance required, they are a practical and long-lasting solution for your home.


Did you know that expanded cork is a completely natural material? Harvested sustainably in Portugal, the bark is removed from cork oak trees every few years. This process doesn’t harm the trees—in fact, it helps them regenerate and grow new bark.
