Is glass wool insulation any good?

2025-09-02

Glass wool insulation is an affordable and commonly used building insulation material around the world.

 

 

Here are its key advantages:

 

Excellent Capability of Insulation: It can reduce the transfer of heat between indoor and outdoor spaces, helping to maintain indoor temperature. Based on this, glass wool helps to reduce energy costs for heating and cooling, and reduce environmental pollution caused by energy use.

 

Sound Absorption: Correct use and selection of glass wool can optimize the noise pollution in your environment. This helps improve the acoustic comfort of your home, office or commercial space.

 

Fire Resistance: Most glass wool products are non-flammable (fire rating A1), which improves the safety of buildings in the event of fire by burning without smoke and limiting the speed of fire spread. This increases the survival rate of people in dangerous situations.

 

Cost-effective: While being more affordable than some other insulation materials, it also provides very good insulation performance in common building use scenarios.

 

Environmental Protection: Glass wool can help to improve building energy efficiency and reduce carbon emissions. Its raw material contains 20%-40% recycled glass. This reduces the amount of industrial solid waste sent to landfill and saves energy required for glass melting. At the same time, glass wool also can be recycled.
