Belgolan is an insulating material (thermal/acoustic) with a very high level of performance in terms of durability and health. The added value of the panels lies in their physical, chemical and mechanical properties, which are far greater than what is required for insulation purposes. Belgolan regulates humidity, prevents heat loss in winter, improves sound insulation, creates a healthy interior and makes the running of your home more efficient.
Sheep’s wool panels are used to insulate exterior walls, interior partitions, floors, roof rakes and lofts. Needle-felt products are not recommended for use in walls because of their poor vertical hold. Sheep’s wool is used within framework (preferably wooden framework). The insulation is cut to the width between the frames, plus two centimetres to ensure a spring effect.
Sheep's wool can absorb up to 33% of its weight in moisture without losing its insulating properties. This is why the vapour barrier is often unnecessary. Furthermore, contrary to popular belief, sheep’s wool does not attract rodents. It has the ability to shrink, preventing rodents from settling there.
We are accredited as a ‘bio-sourced product’ for Belgolan, a unique label for construction materials that combine environmental and economic advantages for both companies and individuals, with a 25% surcharge for insulation work as a key component.
Our semi-rigid panels are 1 m (l) x 1.2 m (L) and come in a range of thicknesses (40, 60, 80, 100, 120 mm). The panels are packaged in batches of five in a recycled plastic bag. This means you have 6㎡ in each pack. Store dry.
Belgolan panels are manufactured in Belgium from locally sourced materials and using techniques that have been perfected over centuries. They are a reflection of the Belgian landscape, character and dedication to high-quality design and production.

Wool fabric/Sheep’s wool
Sheep’s wool has very good sound-absorption properties, for a wide range of situations that require high-level performance. Equip acoustic ceilings with special Belgolan acoustic padding so that you can conduct important meetings in peace and quiet and without losing focus. Woolconcept products are increasingly popular among contemporary architects, building engineers and construction foremen for schools, office buildings, conference rooms and private homes as sound insulation inside installation gaps and suspended ceilings – and for good reason too.
The secret lies in keratin, the building block of the proteins that make up sheep’s wool. The molecules in the side branches of the amino acid are able to assimilate and neutralise harmful substances, such as formaldehyde. This results in a chemical reaction in which the pollutants are bound to these molecules or transformed.
Measure the surface that needs to be insulated, plus a surplus of two centimetres to ensure a spring effect between the structure. Cut the panel and place it between the structure. This can be made of wood, metal or any other rigid material. Based on our experience with installations, Belgolan allows for an increase of 17% in speed compared to other flexible insulation. FYI: sheep’s wool fibres only break after being bent more than 20,000 times.
