SUNTHERM® rock wool strip stands out as a Class A non-combustible material, holding a prominent position as a recommended choice in the JGJ 289-2012 Technical Specification for Fireproof Separation Zone of External Wall Insulation of Buildings. This recognition underscores its reliability and compliance with strict industry standards, making it a trusted option for enhancing building safety. When it comes to balancing energy efficiency, fire prevention, and overall safety, SUNTHERM® rock wool strip emerges as the optimal fireproof insulation material for building fireproof isolation zones. Its versatility shines through as it can be effectively combined with insulation materials (such as EPS, XPS boards, etc.) with combustion performance lower than Class A, thereby significantly improving the overall fireproof performance of the buildings. Specifically designed for use in external insulation systems utilizing non-class A insulation materials, it is installed in the horizontal direction, creating a robust barrier that effectively prevents the spread of fire and enhances the fireproof function of the building's external walls.
One of the key product characteristics is its exceptional heat insulation. The rock wool strip boasts good fiber flexibility, which allows for efficient coverage and sealing of gaps, minimizing heat transfer. Additionally, its low slag ball content contributes to an excellent thermal insulation effect, ensuring that the building maintains a stable internal temperature, reducing the reliance on heating and cooling systems.
In terms of fireproofing, SUNTHERM® rock wool strip is crafted using high-quality raw materials and undergoes a high-temperature manufacturing process. This rigorous production method ensures that the product exhibits superior fire performance. Unlike some other insulation materials, it will not produce combustion drips when exposed to fire, which could otherwise spread the flames. Moreover, it does not generate toxic fumes, a crucial feature that protects the lives of occupants and firefighters in the event of a fire.
Hydrophobic properties are another standout feature. The product has a high water-repellent rate, meaning it resists the absorption of water. Its low quality moisture absorption rate and short-term water absorption further enhance its durability, as excessive moisture can compromise the insulation performance and structural integrity of the material. Additionally, its excellent moisture drainage performance ensures that any accumulated moisture is quickly removed, preventing mold growth and material degradation.
The rock wool strip also offers good strength, thanks to the use of a three-dimensional production process. This advanced manufacturing technique ensures that the product has impressive pressure resistance and tensile strength, allowing it to withstand the various stresses and loads encountered during installation and throughout the building's lifespan.
Marquis resistance is a vital attribute for long-term performance. With a high acidity coefficient, SUNTHERM® rock wool strip can resist the effects of various cyclic climates, including temperature fluctuations, humidity changes, and exposure to harsh weather conditions. This resistance ensures that the insulation system maintains its stable performance over time, guaranteeing a service life that matches that of the building itself.
Sound absorption and noise reduction are additional benefits. The rock wool contains a large number of long and thin fibers that form a porous linkage structure, resulting in high porosity. This unique structure enables the product to effectively absorb and dampen sound waves, reducing the transmission of external noise into the building and creating a quieter and more comfortable indoor environment.
Finally, the product contributes to energy saving and emission reduction. As a high-quality fireproof insulation material, it greatly improves the energy utilization rate of the entire building. By minimizing heat loss in winter and heat gain in summer, it reduces the energy consumption associated with heating and cooling, thereby meeting the strict requirements of building energy saving and contributing to a more sustainable built environment. Furthermore, its ease of application is a practical advantage – the products can be cut arbitrarily to fit various installation requirements, making the construction process convenient and efficient, saving both time and labor costs.
