Benefits Of Using EXNP Insulation Boards
- Low Density, Light weight, easy to carry and install
- Long Fiber, Rigid Needle Punch Tecnology makes EXNP boards Tough and Durable with high mechanical strength and high performing product.
- Our EXNP boards have low CTE and thermal conductivity. The lower the CTE the less expansion and contraction of the board when heated. This in turn increases the life of the furnace and its parts further increasing the efficiency of the furnace.
- Withstand upto 2500 Degrees Celsius
