Rockwool Insulation 50mm products are one of the most widely used standard specifications in the fields of building insulation and industrial protection.This thickness achieves a good balance between insulation performance, structural strength, and material cost, making it a standard configuration in building insulation, industrial insulation, and pipeline protection.As a professional with over 10 years of industry experience, I will guide you to learn more about rockwool insulation 50mm products.
1.Product Forms of 50mm Rockwool Insulation
1.1 50mm Rockwool Slab/Board
This is our most popular product type, accounting for 60% of our 50mm rockwool sales. It is made by high-temperature melting of natural basalt, adding professional binders, and pressing and shaping. The product has high compression resistance (≥15kPa), fixed shape, and can be easily cut with a utility knife, which is convenient for on-site construction. It is not easy to collapse or deform when filled in wall cavities, ensuring long-term insulation and soundproofing effect.
We provide four standard density grades, each matched with targeted application scenarios for optimal cost-effectiveness, detailed as follows:
Standard Density and Applications of 50mm Rockwool Slab
- 60kg/m³: Lightweight and cost-effective, the basic grade for thermal insulation; Applications: Suitable for basic thermal insulation scenarios, such as attic filling, non-load-bearing wall insulation, and simple roof thermal insulation, ideal for projects with low budget and only basic heat preservation needs.
-
80kg/m³: Our hot-selling grade, with balanced thermal insulation and sound absorption performance;
Applications: The most versatile option, perfect for residential interior partition walls, commercial office ceilings, roof insulation, and residential energy-saving renovation, balancing performance and cost.
- 100kg/m³: Enhanced grade, with improved sound absorption and compression resistance;
Applications: Ideal for scenarios with high acoustic requirements, including KTV rooms, recording studios, office partitions, and load-bearing wall insulation, effectively absorbing noise and withstanding certain pressure.
- 120kg/m³: High-density heavy-duty grade, for high-performance and industrial scenarios;
Applications: Designed for industrial and heavy-duty use, suitable for industrial fire barriers, factory fire partitions, prefabricated sandwich panel cores, and high-temperature adaptive scenarios, with strong compression resistance and fireproof performance.
1.2 50mm Rockwool Blanket/Roll
The flexible 50mm rockwool blanket is produced by a continuous winding process, with soft texture and good ductility, which can be freely bent to fit curved surfaces such as pipes, steel structures, and irregular cavities. The standard roll width is 600mm or 1200mm, and the length can be customized according to the project volume (10m-50m/roll), which is suitable for large-area laying and improves construction efficiency.
Production advantage: We use high-quality glass fiber mesh reinforcement inside the blanket, which enhances the tensile strength of the product, avoids tearing during construction, and extends the service life of the product.
To meet diverse project requirements, we provide four standard density grades: 60kg/m³, 80kg/m³, 100kg/m³, and 120kg/m³, each tailored for specific application scenarios.
- 60kg/m³: Lightweight and cost-effective, focusing on basic thermal insulation; Applications: Ideal for large-area roof/attic insulation, non-load-bearing wall filling, and general thermal insulation projects; perfect for budget-conscious projects prioritizing basic heat preservation.
- 80kg/m³: Our best-selling density, balancing flexibility, thermal, and acoustic performance; Applications: The most versatile choice, widely used in steel structure roof/wall insulation, HVAC duct wrapping, and residential energy-saving renovations; offers optimal cost-performance for general construction needs
- 100kg/m³: Enhanced density with improved sound absorption and structural stability; Applications: Specially designed for sound-sensitive spaces such as KTVs, recording studios, and office partitions; effectively absorbs medium and high-frequency noise while maintaining good flexibility
- 120kg/m³: High-density heavy-duty grade, suitable for high-load and industrial scenarios; Applications:For heavy-duty industrial applications, including factory fire barriers, high-temperature pipeline insulation, and prefabricated building components; delivers exceptional compression resistance and fire safety.
2.Standard Sizes & Customization
We provide standard sizes to meet the needs of most projects, and also support full customization according to your order quantity and construction requirements:
-
Slab/Board: Standard size 1200mm×600mm (can be customized to 1000mm×600mm, 1200mm×800mm, etc.)
-
Blanket/Roll: Standard width 600mm/1200mm, standard length 10m/20m/30m (customizable length up to 50m)
-
Foil-Faced & Wire Mesh Types: Same as standard sizes, can be customized according to the width and length of the project
