Where Can I Apply Rockwool Insulation Slabs?
Due to the rigid, semi-rigid and flexible nature of stone wool insulation, Rockwool slabs offer outstanding thermal and acoustic protection in internal walls and floors.
They can also be slotted into spaces like 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. Overall, Rockwool can be considered for roof, floor and wall insulation.
Stone wool insulation is also water repellent while simultaneously allowing water vapour to pass through. This makes Rockwool slabs a great addition to ceilings and basements, where moisture and damp could otherwise pose problems.
The slabs can be used for the following construction types:
- Interior timber or steel partition walls
- Interior timber frame floors
- Interior timber frame ceilings
- Pitched roofs
- Acoustic ceilings and partition panels
- I-joist interior partitions
- Party walls
Rockwool Insulation Slabs Key Features
- Semi-rigid - Rockwool slabs are semi-rigid meaning you do not have to worry about bowing or sagging over time.
- Reduces sound transmission - Rockwool slabs are designed to reduce sound transmission. Rock is a naturally poor conductor of sound, making Rockwool the perfect choice for people who want to insulate their homes against unwanted noise.
- Fire-Protection - Rockwool slabs are manufactured using anti-flammable, thermal insulation material. They are made in part from basalt, a volcanic rock that is highly fire-resistant. The slabs rank Euroclass A1 non-combustible.
- Thermal Efficiency: Our RWA45 products boast a lambda value of 0.035 W/mK.
- Moisture Resistance: Rockwool insulation is both moisture resistant and vapour permeable.

Designed to impede sound transmission between rooms, Rockwool resin-bonded slabs are purposed to quell unwanted sounds and prevent voice leaks in your home, helping you to live in sweet, manufactured silence.
Rockwool Fire Performance
Not only do these premium-quality semi-rigid slabs excel in their soundproofing abilities but they are also rated A1 (non-combustible) on the Euroclass scale, meaning they are first-rate performers when it comes to reducing fire spread.

Frequently Asked Rockwool Insulation Slab Questions
What Density Is Rockwool Sound Insulation Slab?
The density of Rockwool is measured in kilograms per cubic metre (kg/m3).
Each product type has a different density. We stock RWA45 that are available in a range of thicknesses and have a density of 45 kg/m3. Our RWA45 products are popular middle-of-the-range options that fit lots of insulation needs.
How Should I Store & Handle Rockwool Insulation?
Rockwool insulation slabs have a soft, fibrous texture, similar to a loaf of bread. Because of this, a serrated blade is all you need to slice through it.
When it comes to storage, we advise that you store the slabs inside.
Is Rockwool Insulation Fireproof?
Rockwool insulation’s fire performance rating is excellent. The slabs can withstand temperatures up to a whopping 1,000 celcius.
Rockwool insulation slabs are classed as A1, the highest possible level on the Euroclass system, which means that they are fire retardant in accordance of BS EN 13162.
Is Rockwool Waterproof?
Rockwool insulation is moisture resistant and vapour permeable.
Engineered to repel water, water will drain away rather than soak into the insulation, while gaseous water vapour will simply pass through it.
Therefore, if Rockwool gets wet, you can dry the material out and it will maintain its original performance characteristics.
