Siding insulation made of Neopor® GPS provides maximum performance benefits by completely filling the gap between the siding and your home. With the addition of GPS-based contoured insulation, your new siding will be more durable, more beautiful and will reduce your utility bills for years to come.

Adding Neopor GPS insulation behind vinyl siding can significantly improve the impact resistance of the panel, because the foam acts as a shock absorber to dampen the blow, limit the amount of flex, and support the return to shape. In addition, Neopor GPS adds strength to the product, reducing the possibility of the siding getting damaged by wind, debris and pests. The result is an extended life for the siding.
