what are the benefits of glass wool?

2025-09-22

Glass wool is a very common and widely used insulation material. it has the following major advantages:


1. Outstandingthermal insulation and heat preservation perfomance (core advantage)
This is the most prominent advantage of glass wool. lt is composed of countless tiny glass fibersthat are interwoven together, and the spaces between the fibers form a large number ofstationary air layers. These air layers can effectively prevent air flow, thereby significantlyreducing heat conduction.
Winter: lt can prevent the loss of indoor heat, keep the room warm, and save heating costs.Summer: lt can block the entry of external heat into the room, keep the room cool, and save airconditioning cooling costs.

 

2.Sound Absorption

 It has good acoustic properties, absorbing sound waves and reducing noise transmission between rooms or from outside.

 

3.Fire Resistance

Glass wool is non-combustible with Class A1 fire resistance, meaning it doesn’t catch fire, which enhances building safety.

 

4.Moisture Resistant:

It doesn’t absorb water easily, preventing mold growth and maintaining its insulating properties even in damp conditions.

 

5.Lightweight:

Being light makes it easy to handle and install, even in hard-to-reach areas.

 

5.Durable

It doesn’t settle or degrade over time, ensuring long-lasting performance.

 

 

In summary, glass wool has established its core benefits as an ideal building material with its outstanding thermal insulation and heat preservation performance, highly efficient and long-lasting sound absorption and noise reduction capabilities, stable and reliable A1-level fire resistance and non-combustibility, as well as excellent moisture resistance, corrosion resistance and chemical stability. It not only makes significant contributions to energy conservation and consumption reduction in buildings and enhances living comfort, but also provides great convenience for modern architectural design and construction with its light weight and ease of installation. Choosing glass wool means choosing a guarantee of tranquility, safety and long-term energy conservation.
