Expanded insulation cork boards

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.

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.

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.

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.

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.

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.
