Expanded insulation cork boards

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.

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.

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.

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.

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.

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.
