Exterior wall insulation rock wool board, non combustible, fire-resistant, thermal insulation, sound absorption and noise reduction

Release Time: 2025-11-25

The insulation and fire prevention of building exterior walls are closely related to the living experience. Choosing the right high-quality material can not only keep the house warm in winter and cool in summer, but also strengthen the safety defense line. Today, we would like to recommend the exterior wall insulation rock wool board from Rosewool Insulation Refractory Co.,Ltd - which combines A-level fire prevention, efficient insulation, sound absorption and noise reduction, and has become a reliable choice for many construction projects.

The most reassuring thing is its solid A-level fire resistance performance. As the "outer garment" of a building, fire safety is crucial for the exterior walls. The exterior wall rock wool board of Rosewool Insulation Refractory Co.,Ltd is made of high-quality raw materials such as natural basalt, which are melted and processed at high temperatures. Its combustion performance meets the A-level non combustible standard. Even in the event of an unexpected fire, it can effectively block the spread of flames, delay the spread of fire, buy valuable time for personnel evacuation and property protection, and put "fireproof armor" on buildings.

The insulation effect is as expected. During the winter and summer seasons, building energy consumption often remains high. However, this rock wool board, with its unique fiber structure, can form an effective insulation barrier, locking in indoor heat during winter and preventing outdoor high temperatures from seeping in during summer, ensuring a comfortable and stable indoor temperature. Not only can it enhance the living and usage experience, but it can also help buildings reduce energy consumption for air conditioning and heating, contributing to environmental protection and energy conservation. Long term use can also save a lot of expenses.

In terms of sound absorption and noise reduction, it has also demonstrated outstanding capabilities. The traffic noise and crowds in the city often affect indoor tranquility. The porous structure of rock wool board can effectively absorb sound waves, reduce noise propagation, and create a quiet and comfortable indoor environment. Whether it's residential buildings, office buildings, schools, hospitals, or other noise sensitive places, they can all use it to isolate external interference and restore a peaceful space.
