Rock Wool Slab

About Rock Wool Slab

A 50mm Rock Wool Slab refers to a type of insulation material made from rock fibers compressed into dense slabs. Rock wool, also known as mineral wool, is a versatile and effective insulation material used in various construction and industrial applications. Here are some key features and considerations related to a 50mm Rock Wool Slab:

1. Material Composition

- Rock wool is primarily composed of natural rock materials such as basalt or diabase, which are melted at high temperatures and then spun into fibers. These fibers are bonded together using a binder and compressed into dense slabs or batts.

2. Thickness

- The term "50mm" indicates the thickness of the Rock Wool Slab, which is 50 millimeters or approximately 2 inches. This thickness is suitable for applications where moderate insulation is required, such as walls, ceilings, floors, and roofs.

3. Thermal Insulation

- Rock wool has excellent thermal insulation properties, helping to regulate indoor temperatures by reducing heat transfer through walls, ceilings, and other building components. A 50mm Rock Wool Slab provides moderate thermal insulation, which can help improve energy efficiency and comfort in buildings.

4. Fire Resistance

- Rock wool is non-combustible and has a high melting point, making it highly resistant to fire. It can act as a fire barrier, helping to prevent the spread of flames and protect the structural integrity of buildings.

5. Acoustic Insulation

- In addition to thermal insulation, Rock Wool Slabs also provide effective acoustic insulation by absorbing sound waves and reducing noise transmission between rooms. This can help create quieter and more comfortable indoor environments.

6. Moisture Resistance

- Rock wool is resistant to moisture and does not absorb water, making it suitable for use in humid or damp environments. It will not promote mold or mildew growth and maintains its insulating properties even when exposed to moisture.

7. Density and Rigidity

- Rock Wool Slabs are available in different densities, ranging from low to high density, to meet specific insulation requirements. A 50mm Rock Wool Slab typically has a moderate density, providing both thermal insulation and structural support.

8. Installation

- Rock Wool Slabs are easy to install and can be cut to size using a utility knife or saw. They can be friction-fitted between studs, joists, or rafters, or installed with mechanical fasteners or adhesive. Proper installation techniques ensure maximum insulation performance.

9. Environmental Considerations

- Rock wool is a sustainable and eco-friendly insulation material, as it is made from natural and abundant rock resources. It is also recyclable and can be reused or repurposed at the end of its service life.

10. Code Compliance

- Rock Wool Slabs typically meet or exceed building code requirements for thermal and fire performance. When selecting and installing Rock Wool insulation, it's essential to comply with local building codes and regulations.

Overall, a 50mm Rock Wool Slab offers effective thermal and acoustic insulation, fire resistance, and durability, making it a versatile choice for a wide range of construction and industrial applications. When specifying or installing Rock Wool insulation, consider factors such as thickness, density, installation method, and environmental impact to ensure optimal performance and compliance with project requirements.

Superior Fire Resistance and Safety

Rock Wool Slabs stand out for their non-combustible nature (Class A1, ASTM E84), offering peace of mind in fire-prone environments. They are asbestos-free, odorless, and manufactured from natural volcanic rock, ensuring both safety and sustainability for any project.


Unmatched Acoustic and Thermal Performance

These insulation slabs deliver high levels of sound absorption (NRC up to 1.0) and low thermal conductivity (0.035-0.045 W/mK), making them ideal for reducing noise and heat transfer. Their performance remains consistent, even in damp or humid settings, due to their excellent moisture resistance.


Easy Installation, Long-lasting Results

Highly compressible Rock Wool Slabs can be dry-fitted and cut to size for seamless installation within stud or cavity frameworks. Supplied in protective polythene packaging, they resist corrosion, maintain integrity for over 30 years, and come in various customizable thicknesses and densities.
