Expanded insulation cork sheets are natural, balanced and unbeatable cork products that, with this special type of agglomerated cork, do not contain polyurethane or any other fillers or additives. Due to the high temperature processing treatment it expands (similarly to popcorn) and suberin that is releases during is a natural adhesive that binds the expanding grains. This way we produce a wonderful, natural and sustainable material that offers a perfect vibroisolation, thermal insulation and acoustic isolation.

A noisy neighbour?

Expanded cork wall panels can be a great mean for insulation and thermal isolation. Fixed on the wall or ceiling is an acoustic insulation and eliminates all the sounds coming from the other side. If the wall is thin and the noise is of great inconvenience, it is worth to consider a light construction of 30-40mm cork insulation panel, air gap or mineral wool and closing plasterboard or OSB panel. In the majority of cases the placement of the 10mm wall cork insulation panel will be sufficient for reducing the noise.

Looking for a little privacy?

If the issue at hand is more serious than just a loud TV then a expanded decorative cork insulation panel is an answer to the problem. A panel 20 to 25mm thick will be enough to achieve privacy in one’s own home. It is worth not finishing the cork panel after the fixture as its irregular structure will disperse sounds more effectively and eliminate any echoes, increasing our comfort. As the technical cork may not be appealing to everyone, we offer a wide range of decorative cork.

Freezing outside and the walls are ice-cold?

40 million cells full of air in every cubic centimetre gives thermal conductivity of 0.037 W/mK. What does this mean? It means no more high gas bills and much more warmth in the apartment. Just 10-15mm expanded cork insulation panel is enough to make even the coldest walls warm to the touch. But the 20-25mm cork insulation sheets will provide enough insulation and will keep the warm air inside to turn it into a comfortable and cosy living space.

How to fix 50x100cm cork insulation panels and what tools to use?

Expanded cork wall tiles are a fine material that can be fixed in a variety of ways. The cheapest and the easiest method to fix it is by gluing with cork glue. We recommend Wakol D-3540 that can be found in our ‘Cork Glues’ section. Our advice is to use around 100 grams of glue per 1 tile, which means that 0.8kg of glue is enough for 8 tiles, and a bucket of 2.5kg – 25 sheets. Of course using cork glue is not obligatory. The most widely used fixing glues and strong wood binders. It is best to choose a product with good initial tack, as it will make the job easier and faster, especially for the less experienced.

In case of fixing the cork insulation panels to the ceiling we do not recommend using the glue alone. In such a case it is advised to strengthen the panels by joining the fixture with pins.

Paint, lacquer or wallpaper – which finishing?

Expanded cork insulation panels can be left alone without any finish. They can also be finished in any way possible. Cork wall panels can be painted over with any paint, lacquer or wood stain to enhance or cover up the cork’s structure. If the cork board rolls will be exposed to dirt and will be washed frequently, it is worth finishing it with a protective product. The cheapest and least labour intensive way to finish it is... leaving the cork wall unfinished! The original structure of the black cork will bring a new and natural dimension to the interior and furthermore such a cork wall can be a perfect cork pin board for the whole family!
