Expanded cork 25mm

Expanded cork panels are manufactured by the Portuguese company Amorim. They represent a natural, sustainable, and in many ways superior alternative to polystyrene or mineral wool. These panels are used in the following applications:

• Thermal and acoustic insulation of horizontal and vertical partitions, both inside and outside buildings
• Thermal and acoustic insulation of terraces, flat and pitched roofs
• Filling of expansion joints and gaps

• Thermal insulation of cold rooms and refrigeration chambers

• Thermal insulation of pipelines
• Vibration insulation for the foundations of machinery and equipment
• Base material for bonding with other materials such as aluminum, metal, plywood, etc.
• Material for decorating terrariums and vivariums (animal enclosures)

General product features:

• 100% natural and eco-friendly material
• Virtually unlimited lifespan
• Technical parameters remain stable over time
• Excellent dimensional stability over many years
• Does not emit toxic gases in case of fire
• Resistant to many chemicals, insects, and rodents
• 100% recyclable
