Insulated Sandwich Panels

Rockwool Sandwich Panel

Rockwool sandwich panels are referred to as a type of thermal insulation made from rocks and minerals. It is also called mineral wool. Rockwool sandwich panels are used to enhance the acoustic performance of the system in which the material is installed in both new and existing buildings.

This fibrous material is formed by spinning or drawing molten minerals or any rock material. These panels have a metal sheet covering on either side with Rockwool filling in between. The panels are highly preferred for their thermal conductivity, low combustibility, high mechanical resistance, sound absorption, and fire prevention.

Rockwool panels are installed in walls, floors, ceilings, attics, and crawl spaces. It offers protection from cold, heat, the risk of fire, and ambient noise.

The Advantages of our Rockwool Panels are-

1. Absorb sound waves – 

We improved the internal sound field quality by absorbing echo and reverberation within the room, contributing to good room acoustics.

2. Insulate unwanted noise-

The Rockwool reduces sound transmission, blocking the passage of sound from the outside to the inside of the building, and from one room to another.

3. Control vibration-

We manufacture the Rockwool resilience that leads to the isolation and damping of vibration.

4. Durable and flexible-

Rockwool insulation should last the lifetime of your building if installed in a properly designed system according to spec. Rockwool products will not decay since they are inorganic, so they will retain their properties assuming no physical damage occurs.

5. Sustainability and energy efficiency-

Rockwool panels are made from stone wool which is a highly sustainable source that can be infinitely recyclable. Whenever we build or renovate or demolish any building, it can be easy to remove and reuse the Rockwool panels into new products like Fire rated doors.

6. Fire resistance for occupant safety-

With a temperature of more than 1000 degrees C, our  Rockwool sandwich panel doesn’t contribute to the development and spread of fire or release any toxic gases.

7. Excellent sound absorbent for acoustic comfort-

It has a non-directional structure which helps Rockwool panels insulation is denser than traditional insulation products. That helps to absorb acoustic energy and waves to reduce the intensity and propagation of noise.

8. Water resistance-

Rockwool panels have the good property of wall repellent. This is due to the inherent drying potential of the product which is also resistant to rot, mold, and mildew growth that contribute to a safer indoor environment.

9. Dimensional stability-

Rockwool panel retains the characteristics over time which simply means, it reduces the maintenance over the life of the building. Even with temperature change or humidity for long periods, changes in Rockwool panels work the same.
