Cork granules per bag 100L

Product information

In Belgium, collected natural cork stoppers from wine bottles are processed into insulation granules. This way, the cork stoppers do not end up in the landfill but are given a second life as high-quality insulation material.

Cork granules retain their unique properties over time and can be used repeatedly, resulting in a particularly circular product.

Cork is naturally resistant to moisture. In very humid environments, such as cavity walls in facades, expanded cork granules are preferred.

These granules can be applied between beams as acoustic and thermal insulation. They also ensure a seamless fit when filling cavities with pipes. Even refilling partition walls from above poses no problem; the granules effortlessly fall into place.

Cork performs excellently acoustically due to its ability to absorb sound waves (e.g., to reduce reverberation) and achieve acoustic decoupling (e.g., to reduce impact noise between floors).

When cork granules are used in a grid or between wooden beams in floors or ceilings, they provide excellent acoustic and thermal insulation. Their high density and damping structure contribute to effective sound absorption.

Cork granules are also suitable as a filling material for technical cavities and ducts. Thanks to their small size, they slide down smoothly and fill the space without difficulty.

Staenis practical advice

Cork granules are a non-load-bearing insulating fill; the grid and boards support the floor. Use the green fibre-reinforced Staenis dry-floor grid and fix its feet with PU foam. The 8 additional feet per m² with mortar reinforcement apply to the former black-and-yellow grid, not the green version.
