The combustion performance of the material is crucial, which is not only related to the safety and durability of the building, but also closely related to the safety of people's lives and property. Glass wool felt as a commonly used building thermal insulation material, its combustion performance is non-combustible or non-combustible?

According to the "Classification of Combustion Performance of Building Materials and Products", Class A non-combustible materials refer to materials that are not burned in the combustion test or the combustion time is less than or equal to 10s, and there is no large amount of open smoke. The B1 grade refractory material means that under the specified test conditions, the sample is difficult to burn, and can immediately extinguish itself after leaving the fire source or the combustion time is less than or equal to 30S.

Glass wool felt is mainly composed of glass fibers, which are specially treated to form a soft and felt-like material with a certain thickness. Glass fiber is an inorganic material with a high melting point and fire resistance. Therefore, from the material point of view, glass wool felt has better flame retardant performance.

In fact, glass wool felt can reach Class A non-combustible material. The burning point of glass wool felt is usually higher, generally around 500 ° C, and the melting point is higher, reaching about 800 ° C. This means that under normal circumstances, glass wool felt is not easy to burn. At the same time, when the external fire source leaves the glass wool felt, the fire source is usually extinguished quickly, which further proves its good flame retardant performance.

In addition to combustion properties, glass wool felt has other advantages. For example, it has good thermal insulation performance, which can effectively reduce the transfer and loss of energy; At the same time, the glass wool felt also has a certain sound absorption performance, which can improve the quality of the indoor environment. These advantages make glass wool felt favored in the market.

Glass wool felt is a non-combustible material with high temperature resistance, which can improve the fire safety of the building. In addition to the fire performance, the thermal insulation and sound absorption of glass wool also create a more comfortable living environment for people.
