Rigid, vacuum-formed boards combining the insulation of ceramic fiber with hard texture and high compressive strength.
TOPWOOL ceramic fiber boards adopt the corresponding blown fiber as raw material and are produced by vacuum-forming technology. They are pure white in colour with low shot content, manufactured on a fully automated production line with a continuous process.
TOPWOOL ceramic fiber boards not only retain the insulation function of the fiber, but also feature a hard texture, excellent toughness and strength, and outstanding fire-resistance and heat-preservation performance.
