Brownie Slab Advantages

  • Fire resistant (class A1) building material 

  • Improves air quality - Formaldehyde free and unlikely to cause allergic reactions. Low VOCs (ASTM D 5116)

  • Optimal fibre diameter/network - 4-5 microns producing more air chambers to improve performance whilst creating better tensile strength to provide superior durability and flexibility 

  • Less dusty and less itchy - East to work with, engineered for comfortable installation

  • Non Corrosive - Will not cause accelerated corrosion of steel, stainless steel, copper or aluminium (ASTM C665-12)

  • Excellent Thermal qualities - Keeping rooms warm in winter and cool in summer 

  • Mould resistant - does not encourage growth of mould, fungus, bacteria or rodents (ASTM C1338-08)

  • Low water absorption - Absorbs less that 5% by weight (ASTM C1104) 

  • No smell - Does not emit any odor (ASTM C1304)


Eco-Wool Products
