Heat Insulation Effect
The product has the good heat insulation that has been checked through GB/T10294-1988 standard, in the average temperature 70±5â, heat conduction coefficientâ¤0ï¼043Wï¼mK. The data listed below is the comparison of various building materials with the same heat insulation effect of glasswool felt in the standard of unit weight 10kgï¼m3, thickness100 mm.



Glasswool Felt 100mm
Wood 280mm
Plywood 350mm
Flat Glass 1790mm
Concrete 3680mm
Plasterboard 450mm

As the conclution, glasswool has the great heat insulation effect of 3 times of wood and 37 times of concrete.

Sound Absorbing Effect (Face glasswool felt)
Sound Absorbing Coefficient

Unit Weight(kg/m3) Thickness(mm) Face Type Octave Band Central Frequency(Hz)
125 250 500 1000 2000 4000 NRC
16 50 Enhonced Aluminum Foil 0.23 0.80 1.25 0.86 0.42 0.26 0.85

NRC-Denoise Coefficient

If use the face of thin or glasscloth and other ventilate faced material, there are no changes of sound absorption. However, if coating on the surface of the glasswool or face, the sound absorption will be reduced in depend.
