Silica/Fiberglass Composite Felts & Blankets


Lewco can combine our Silica and Fiberglass insulation felts into needled composites that for many insulation applications can give customers the pricing advantage of Fiberglass with the high temperature properties of Silica fiber. Lewco can combine these two different felts introvarious thickness combinations to meet customer requirements. These insulation felt and blanket composites are strong enough to give long life in tough, difficult applications. Applications include: Stress Relief blankets, Removable/Reusable Insulation for high noise level, high maintenance, high vibration and high temperature equipment or engine exhaust systems.
