Mineral wool blown-in insulation stands out for its exceptional qualities, making it a top-notch choice. Here are the details of its benefits and effectiveness:
● Good Thermal Insulation
Mineral wool possesses an open fibre structure that traps significant air. This property makes it an excellent insulator that is useful for heat regulation. Its low thermal conductivity, with a lambda value ranging from 0.03 W/mK to 0.04 W/mK.
The lambda value ensures that it remains thermally efficient throughout the lifetime of your building. Additionally, mineral wool insulation remains stable. It means that it won’t expand or shrink, reducing the risk of thermal bridges.
● Fire Safety
Insulation of mineral wool is fully fire-resistant and does not conduct heat, making it ideal for various applications. It is commonly applied in fire-retardant products/ for example, protective clothing, fireproof doors, partition walls, and ceilings.
Specifically, insulation of mineral wool is categorized under Euro Class A, boasting the best score among insulation materials for high-temperature applications.
● Impressive Soundproofing
In addition to thermal performance and fire resistance, the insulation of mineral wool also excels in soundproofing. Its unique structure and composition make it effective in pushing noise pollution.
Special acoustic tiles designed for walls, floors, and ceilings can absorb the waves of sound, making them valuable in both industrial and residential settings. For instance, rock wool blankets are frequently used on walls, floors, and ceilings to enhance sound absorption.
