ROCKWOOL insulation slabs can be installed inside walls, outside walls, under floors, above ceilings and in roof spaces – helping to protect buildings against excessive noise, heat loss and the spread of fire.

You’ll find an array of effective ROCKWOOL slabs in our range. 

Each offers different sizes, thicknesses and densities, providing an effective solution for any residential or commercial property – from flats and offices to hospitals, shopping centres and schools.

Insulation Slab Products

Where and how can our products be used?

We offer a wide range of robust, adaptable products suitable for an array of applications. 

They’re ideal for many different functions when installed in a building. Our range includes cavity wall insulation slabs, loft insulation slabs and flooring solutions to name but a few, with external façade and roof applications also a key part of our offering. 

Due to the rigid, semi-rigid and flexible nature of our stone wool insulation slabs they can easily be installed in a variety of applications. They can be slotted into spaces like cavity and partition walls with ease, whether these have a brick, concrete, timber frame or other base structure. This also ensures they are easy to lay in-between floors as sound insulation slabs too. 

Stone wool is water repellent while simultaneously allowing water vapour to pass through. This makes our slabs a great addition to ceilings and basements, where moisture and damp could otherwise pose problems.

 

Cavity wall

Slotted into cavity wall spaces to block cold air passing through.

Roof Insulation

Properly installed, slabs can improve thermal regulation and reduce the impact of external noise. 

Acoustic insulation 

Nuisance noise is reduced from floors and walls in connecting flats and homes.

Loft insulation

Slabs can reduce heat loss in attics and lofts – a prime source of this.

Fire protection

Insulation slabs work to reduce the spread of flames and are non-combustible.

External wall

Excess draughts are blocked but homes still ventilated through external walls.

Floors

Sounds are blocked and heat loss decreased through floor spaces.

Why do we need insulation slabs?

When it comes to regulating temperatures, protecting against fire and blocking out sound, insulation slabs developed by ROCKWOOL solutions can be an important addition to any building.

 

They work as a multi-purpose solution that can help:

  • Drive down energy bills – by keeping more heat in during the chilly months, occupants won’t have to turn on the heating as much, keeping those bills down.
  • Reduce nuisance noise – flats and terraced housing are at greater risk of noise travelling between walls and floors. Slabs are effective at reducing this.
  • Keep buildings cool and warm – insulation slabs can repel warmth during the summer and contain heat in the winter, keeping temperatures level all-year-round.
