Why choose our glass wool insulation?

Because of our glass wool insulation effectiveness, safety, and value. It will not lose its insulating power (R-value). Our main raw material is recycled glass, so it is naturally noncombustible. We use a plant-based binder with no added formaldehyde, harsh acrylics, or unnecessarily fire retardants.



Glasswool Application

Glass wool board is designed to meet the needs of the large-scale laying of the coil, to maintain the characteristics of thermal insulation, but also has very excellent shock absorption, sound absorption characteristics, especially in the low frequency and a variety of vibration noise Have a good sound absorption effect, improve the working environment. This product can be customized according to the needs of any arbitrary, mainly for the construction of indoor, muffler systems, transport, refrigeration equipment, household appliances shock absorption, sound absorption, noise reduction, the effect is very satisfactory.
