PIR Foam Board used for Solar Heater Rigid Insulation.

Greenfoam (GFI) Pre-insulated Duct Panel, also known as Rigid PIR Foam Board, have been used for Solar Heater Rigid Insulation successfully. The Solar Heater manufacturer previously used glass wool as thermal insulation, they took our PIR Foam Board by instead since the year of 2013.

This PIR Foam Board consists of 50kg/m3 PIR foam insulation faced on both sides with 80 micron or 200 micron thick aluminum sheet. Compared with glass wool, PIR Foam provide higher thermal efficiency. The thermal conductivity lamda value of glass wool is higher than 0.04W/m.K, while PIR foam is less than 0.025 W/m.K. Also the rigid PIR foam can provide higer compressive strength, and it’s water proof.

We can produce PIR Foam Board in different thickness, from 10mm to 40mm. The max width is 1220mm, and the length can be cut according to customers’ requirement.
