Thermal Conductivity:
RWA45 by Rockwool is a mineral wool insulation. It has a low thermal conductivity of 0.035 W/mK, which means that these insulation slabs do not let heat pass through their fabric easily. It also means that the heat remains trapped in its fabric, which converts to lower energy bills.
Acoustic Insulation
By adding mass to any application, you help improve its soundproofing abilities. Similarly, when you insulate walls or roofs with high-density mineral wool, like Rockwool RWA45, you soundproof it.
Mineral wool absorbs sound waves. They absorb both impact and airborne noise. In short, RWA45 is the way to go if you want some privacy from your noisy neighbours or if you want a little break from your kids shouting or singing at the top of their voices!
Fire Insulation:
Rockwool RWA45 is A1 Fire rated by Euroclass. It is non-combustible in nature, that is, it does not contribute to fire in any way. RWA45 gives you extra peace of mind when it concerns the safety of your loved ones.
Water-Resistant Batt insulation
Insulation Slabs by Rockwool are water-resistant in nature. They are also breathable, which means they allow moisture to pass through them easily. This does not mean they retain water. By letting water vapours pass through their fabric, RWA45 reduces the risk of mould formation.
Easy to Install:

How do you cut RWA45 slabs?
RWA45 is easy to cut. You can use a sharp utility knife to cut the batt insulation to the required size.

Yes, RWA45 gives excellent sound insulation. With a density of around 45kg/m3, RWA45 absorbs sound waves very effectively.
Can RWA45 treat condensation on internal walls?
Due to their breathability, water resistance and thermal qualities, RWA45 aids in lowering the likelihood of dampness in applications. But RWA45 will be affected by moisture if you have any pre-existing moisture-related conditions and their thermal performance will decrease.
