25mm Glass Wool Blanket Sound Insulation Guide

25mm thick glass blanket sound insulation material? A 25mm thick glass wool blanket is a basic material that performs well in both insulation and sound insulation. Its core function can be summarized as: effectively blocking heat conduction and sound propagation through a large number of tiny static air layers inside, thereby achieving the effects of "warm in winter and cool in summer" and "quiet noise reduction". 25mm thick glass wool felt is a multifunctional material that integrates insulation, heat insulation, sound absorption, and fire prevention. However, its sound insulation (isolating external noise) and sound absorption (absorbing indoor echoes) effects are significantly different.
                                                                                          

Introduction to common functional effects of 25mm thick glass wool blanket

1. Low thermal conductivity

This is the core indicator for measuring insulation effect, and the lower the value, the better. The thermal conductivity of high-quality 25mm glass wool blankets is usually between 0.032 and 0.042 W/(m · K). This means that it can effectively prevent heat transfer, whether it is winter insulation or summer insulation, the effect is significant.

2. Wide applicable temperature range

The applicable temperature of glass wool blanket is usually between -120 ℃ and 400 ℃, which can meet the conventional insulation needs of most industrial and construction fields. For higher temperature scenarios, high-temperature products that have undergone special treatment can be chosen.

3. Stable performance

Its chemical properties are stable, not easily affected by moisture, and can maintain good insulation performance for a long time.

4. Sound absorption and noise reduction

This is one of the core advantages of glass wool felt, but it is necessary to distinguish between "sound absorption" and "sound insulation".

5. Fire safety

Glass wool belongs to Class A non combustible materials, which do not burn or produce toxic gases when exposed to open flames. It can self extinguish after leaving the fire and is an important guarantee for building fire safety.

6. Thermal insulation

The fibers inside the glass wool felt are fluffy and interlaced, forming a large number of tiny static air layers that can effectively block the conduction of heat.
