Overview - RW Slab Range
The RW product range consists of premium resin-bonded slabs in a host of thicknesses and densities. On the market, specialist sizes and thicknesses of RW are available, as well as black or white tissue and aluminium foil facings.
RW slabs showcase all the hallmarks of Rockwool's expertise:
- 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 insulation 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 and resist high temperatures.
- Thermal Efficiency: RW products boast a lambda value of 0.035 W/mK.
Frequently Asked Rockwool RW3 Slab Questions
How Does Rockwool RW3 Insulation Reduce Sound Pollution?
Rock is a naturally poor conductor of sound, making RW3 the perfect choice for people who want to insulate their homes against unwanted noise.
Rockwool respectfully thrashes competitor brands with its prevention of noise transmission from room to room, making it ideal for installation in internal and separating walls.
Rockwool RW slabs work in two distinct ways to dampen sound, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.
Is Rockwool Waterproof?
Although not entirely waterproof, Rockwool insulation is moisture-resistant and vapour permeable.
Rockwool does not wick water, meaning 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.
Can You Touch Rockwool With Bare Hands?
Whilst it won't exactly kill you, the dust from Rockwool can irritate the skin and eyes if the correct PPE is not adorned during handling.
We always advise wearing the appropriate safety gear when working with Rockwool: gloves, goggles and a mask should be worn at all times.
If you are to touch the material with bare hands (not recommended), wash your hands thoroughly with cold water after contact.
How Long Will Rockwool Last Before It Has To Be Replaced?
Should you correctly install the insulation (according to manufacturer guidance), Rockwool slabs should last the lifetime of your structure. Since Rockwool products are inorganic they will not decay and left to it, they should sustain performatively - given that the slabs endure no damage.
