Expanded insulation cork boards

Do traditional insulation materials fail during winter, leaving your home vulnerable to cold and noise? It’s time to switch to something more efficient: expanded cork panels. Engineered for enhanced performance, these panels keep your home warm during freezing days and significantly reduce unwanted outdoor noise. How are they different from standard cork? The key lies in their superior insulating properties, both thermal and acoustic. Adding an expanded cork panel to your walls is like upgrading from standard cork, and it far outperforms polystyrene and mineral wool.

HOW ARE EXPANDED CORK PANELS MADE?

Expanded cork panels start with the bark of cork oak trees, which is ground into granules. These granules are placed into molds and exposed to extremely high heat, causing the cork to expand. Think of it like popping popcorn, but with cork! During the process, the cork turns a rich, dark brown and expands, enhancing its thermal and sound insulation properties. Importantly, no artificial chemicals are added, making it a completely natural and eco-friendly material.

DO EXPANDED CORK PANELS PROVIDE GOOD INSULATION?

Absolutely! Expanded cork panels work as an excellent thermal barrier by slowing down heat transfer through walls. Their unique structure, filled with millions of tiny, closed air cells, keeps the heat indoors during winter, helping you cut down on energy bills.

CAN EXPANDED CORK PANELS HELP REDUCE NOISE?

Yes, they can! Thanks to their porous nature, cork absorbs sound exceptionally well. Whether you're dealing with loud neighbors or outside noise, cork panels can make your home a quieter, more peaceful place.

HOW DO YOU INSTALL EXPANDED CORK PANELS ON WALLS?

Installation is simple! Use a high-quality cork adhesive, like Wakol D-3540. For ceiling applications, you may want to secure the panels with additional fasteners, such as wall plugs, to ensure they stay firmly in place.

WHERE CAN EXPANDED CORK PANELS BE USED?

Expanded cork panels are versatile and ideal for insulating walls, ceilings, and roofs. They perform well in areas where standard cork just isn’t enough.

HOW DO EXPANDED CORK PANELS COMPARE TO OTHER INSULATION MATERIALS?

Expanded cork panels stand out as a sustainable alternative to other insulation materials. Mineral wool can irritate the skin and respiratory system and absorbs moisture, which can lead to mold growth and reduced efficiency. Cork eliminates these issues as it is natural, hypoallergenic, and mold-resistant.


Compared to polystyrene, cork is more durable and significantly easier to recycle, making it a more environmentally friendly choice.


As for polyurethane foam, it can emit harmful fumes in the event of a fire and requires a more complicated installation process. Cork is safe, easy to install, and doesn’t release toxins, even under extreme conditions.

Want to keep your home cozy in winter and cool in summer? Expanded cork panels are a fantastic solution. They provide excellent insulation, helping you save on heating and cooling costs, and reduce outside noise for a more tranquil living space.


Another advantage of cork is its ability to let walls "breathe," creating a healthier indoor environment with better air circulation. Plus, cork is low-maintenance and will last for years without the need for constant repairs.


Did you know that expanded cork panels are a completely natural product? The cork is harvested in Portugal from cork oak trees every few years in a sustainable way that doesn’t harm the trees. In fact, this process helps the trees regenerate and produce new bark.
