90mm RW3

Rockwool RW3 90mm – an insulation material made from rock mineral wool. Rock mineral wool, known as stone wool, is made from raw materials including stone and glass. These materials are heated until they melt and then spun to form a wool-like fibre. Furthermore, the manufacturing process of Rockwool RW3 is sustainable and uses organic materials.

Thermal – RW3 has a thermal conductivity of just 0.034W/mK. The thermal conductivity means less heat will pass through the insulation slabs, keeping internal temperatures level. The thermal properties of the RW3 90mm will also prevent heat / energy escaping the building and save money on energy bills. Less energy escaping will also create a more energy-efficient property.
Acoustic – 90mm RW3 Rockwool Slab insulation has acoustic qualities that work by absorbing sound waves. The absorption of sounds waves prevents sound travelling throughout the building. RW3 dampens vibrations creating a more comfortable environment overall.
Fire – Rockwool is non-combustible and give no contribution to the spread of fire. The RW3 slab will not ignite due to flame exposure. RW3 has a melting point of over 1000 ºc. The 90mm rockwool gives more time for people to leave the building and prevent damage to the building structure, RW3 90mm is the most used thickness when it comes to insulation materials, and it is easy to handle and install. Moreso, the RW3 90mm is a great option should you need to double up on insulation to achieve an unusual thickness.

Key Features Of 90mm Rockwool RW3

  • Lightweight and easy to cut, handle, and install
  • Best possible fire performance
  • Great thermal quality – thermal conductivity 0.034W/mK
  • More temperature controlled internal climate
  • Less noise from neighbouring rooms and properties
  • Long lasting lifespan
  • Durable and reliable
  • Water repellent
  • Low density – 60kg/m3
  • Free from harmful gases (CFC and HCFC)
  • They do not add to the formation of any gases with Ozone Depletion Potential (ODP) or Global Warming Potential (GWP)

90mm RW3 Rockwool Slab Insulation is 1200mm x 600mm with a density of 45kg/m3. Rockwool RW3 has a low density of 60kg/m3, the lower the density the better thermal quality. The RW3 slabs also has made to order slabs available. These slabs come with either ALU foil facings, white tissue facings, or black tissue facings.

90mm Rockwool RW3 Application

The 90mm RW3 shape and size means little cutting required. The 90mm thickness – a standard size slab for installation in most applications. RW3 90mm slabs are rock mineral wool formed into a rectangular shape design. The slabs are manufactured are also for easy installation within the buildings thermal envelope including walls, floors, roofs, and ceilings.
The 90mm is all-round performer and manufactured for a range of general building projects and specialist applications. The multi-purpose slabs – designed for commercial, residential, and industrial buildings. RW3 90mm can be fitted alongside other insulation materials. The material can be doubled to achieve an unusual thickness. In addition, RW3 can also help to meet building requirements and regulations.

See all RW3 applications methods listed below:

  • Ceilings – Suspended ceiling
  • Walls – Steel frame systems
  • Walls – Timber frame systems
  • Roofs – Pitched roofs between rafters
  • Roofs – Flat roofs
  • Ground floors
  • Separating floors
  • Intermediate floors

The slabs are extremely durable and last lasting. The 90mm RW3 will last for as long as the building does, and product performance will not reduce over time. The RW3 90mm is a well-used product within the construction industry. Unlike rigid PIR Insulation boards, RW3 slabs are flexible because of their wool material. The flexible slabs are easy to manipulate into most cavity spaces. RW3 also comes in tightly compressed packaging which is easy to manoeuvre around and store on a construction site.

How To Install RW3 90mm Slabs

Install Rockwool RW slabs in a range of methods from the floor to the roof. Customise the slabs to meet your projects needs if required. Ensure you have confirmed that your chosen insulation material is suitable for your projects needs and meets building regulations.
This is a guide only. Consult a building professional or architect before installing insulation into a property. This will avoid problems that cost time and money.
The most common method of RW3 applications includes metal frame walls and timber frame walls. These methods are well used because the slabs sizes are designed to fit within timber or steel frame applications.
When installing insulation slabs into a frame wall the entire frame should be filled with no gaps. Use the cut offs of the insulation material to fill smaller gaps.
Firstly, Cut and measure the slabs to size, if necessary, to fit into the walls metal or timber frame spacings. Ensure your chosen thickness of the slab, matches the depth of the frame.
Push the slab back into the frame. Tightly but the slabs together if joint to avoid thermal bridging and improve thermal performance. The slabs should sit flush with the frame with no projections.
Fit plasterboards into one side of the frame before installing the RW3 slabs if the frame is a new wall and not against an existing wall. Then push the slabs back against the board to make installing quicker and easier.
When the entire frames filled – measure, cut, and apply plasterboard to the frame with the required fixings. Then apply finishing materials such as beading, scrim tape, plaster, and paint to complete the wall.
