The Natural solution for your interior design project.
The versatility of the burel fabric and its high strength are extremely valued features due to its multiplicity of applications. It resists traction, rupture, pressure, and light exposure, supports intensive use, without changing color and shape, making it ideal for wall coverings, panels, ceilings, dividers, partitions, and creative solutions. That touch of comfort that was missing in any decoration and interior design.
Burel Factory executes custom-made acoustic solutions, giving them a unique identity, highlighted by a wide range of Burel Stitches, Textures and Colors. All made with pure sustainable local wool from the Serra da Estrela mountain range.
Acoustic Performance
100% wool, which reduces sound reverberation and limits its propagation. Very effective sound absorption performance: 100% at 3150khz. Ideal for commercial spaces, offices, hotels and work areas. A natural barrier against the sound.
Thermal Performance
Sheep wool is so dense that it insulates from heat and cold. With a thermal conductivity of only 0.0450 in burel fabric 800g, and a thermal resistance of 0.27m2ºC/W. Ideal for indoor temperature, maintaining a comfortable and pleasant atmosphere.
Permeability Performance
The wool fiber structure is waterproof, with a water resistance of 98.5%, which means that, even absorbing moisture, it dries very quickly. At the same time, it repels dirt, requiring only periodic vacuuming without washing.
Since testing is still underway, we recommend the same precautions as with other fabrics. Burel has the same performance, and natural colors (brown, pearl and sarrubeco) don’t undergo any change in color.

This fully recyclable and biodegradable agroproduct (wool) could be used as a fertilizer
Burel is easily maintained. The fibre structure repels dirt and allows for fast cleaning and drying after accidental spilling. Carpets can be kept clean and just as new, solely with regular vacuum cleaning.
It is possible to machine wash burel fabrics using the wool program at a recommended temperature of 40º C.
Steam ironing is recommended using the wool setting – steam iron.
Different patterns and applications have different results.
All tests are made in concrete floor without any space between the fabric and the concrete.
The results of tests made in walls, including panel structures, are expected to be vastly superior.
All tests with different applications in different patterns are currently being carried out.
