Multi foil Insulation material provide good thermal barrier property,but only with 40mm thickness.Compared with the traditional insulation material, like glass wool, foam, rock wool, Qiyao multi-foil insulation material can give you a very high thermal barrier rate to 7.17㎡*k/w.
The material can seal your roof from the wind and dust as a envelop（especially applied for wood & metal roofing or ceiling system）, keep the inside air flow smoothly, providing you a good ventilation living surrounding.
