Rockwool RW3 75mm Acoustic Insulation Slab

ROCKWOOL RW3 is a slab of extremely reliable acoustic insulation material which enhance the acoustic, fire-proof, and thermal performance of the building/ structure. RW3 is a versatile robust insulation solution that can be used for a range of general building projects as well as specialist specifications such as commercial, leisure, industrial and more. The RW range of insulation is made of high-quality resin bonded slabs which are available in a range of densities and thicknesses that are designed to be used in a wide range of applications including walls, floors, roofs and more. The RW range can be customised with mineral black tissue (60gsm), mineral white tissue (100gsm), and aluminium foil facings, made to order.

The RW3 is 600mm by 1200mm, available in thicknesses from 25mm and 100mm. With a thermal conductivity of 0.034W/mK and a density of 60kg/m3.

The advantages of Rockwool RW3 include:

• Excellent thermal, acoustic and fire insulation
• Water repellent and non-hygroscopic
• Resists high temperatures
• Easy to handle and install
• Cost effective
• No maintenance
• Durable/ Long lasting

The durability of this product gives you high quality insulation that is long lasting and will continue being effective for as long as the building/ structure is intact. These slabs are extremely lightweight and can be cut to any size required using a sharp knife which can make transportation and application of the product simple and easy.

Acoustic Performance: Rockwool products work in two ways to reduce noise which include either absorbing the sounds at surface or by impeding the transmission of sound through an element of the structure. The way Rockwool RW slabs are made, make them ideal for use as a sound absorber, with characteristically high coefficients over a wide frequency range. When thicker rockwool is used and paired with a sheet of plasterboard the noise control can be improved further. These noises include conversation, video equipment, mechanical rooms and ventilation systems.

Fire Reducing: RW3 has fire reducing qualities and will not burn or smoke which provides extra protection and reduces damage and fire spreading within houses and buildings.

Water Repellent: Rockwool RW3 also has water repellent qualities that can prevent moisture building up which can be the cause of damp, condensation and rot that can damage the property’s structure and affect the insulations performance.

Thermal Performance: Rockwool is a mineral wool which provides insulation to the building/ structure by reducing the air flow throughout the building/ structure. Its high thermal efficiency can help reduce energy bills for heating and cooling in residential and commercial buildings. This is due to the outstanding thermal resistance of the wool used in RW3.

What is the difference between the products in the RW range?

The RW range consists of RW3, RW4, RW5, RW6, and RWA45. The difference between these products is the sizes and thickness available and the densities of the products. The most versatile and popular slab is the RWA45. The product should be chosen based on the application method being used and the relevant building regulations.

Rockwool RW3 can be installed in a range of methods. These methods include:

• Walls – metal partitions
• Roofs
• Floors
• Partition panels
• Boiler rooms

Safety:

• Non-combustible A1 Euroclass Reaction to Fire classification

How are Rockwool RW slabs installed?

• Rockwool RW slabs can be installed in a range of methods from the floor to the roof and can be customised 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 and a building professional or architect should be consulted before insulation is installed into a property to avoid problems that cost time and money.
• The most common method of installing RW slabs is within metal or timber frame walls.
• The slabs sizes are designed to fit within timer or steel frame applications.
• When installing insulation slabs into a frame wall the entire frame should be filled with no gaps.
• Cut offs of the insulation materials can be used to fill smaller gaps.

The slabs should be measured and cut 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.

The slab should push back into the frame and if joint, they should be tightly butted together when installed to avoid thermal bridging and improve thermal performance. The slabs should sit flush with the frame with no projections.

If the frame is a new wall and not against an existing wall, ensure one side of the frame is fitted with plasterboards before installing the RW3 slabs so they can be pushed back against the board to make installing quicker and easier.

When the entire frame is filled, plasterboard is then measured, cut, and applied to the frame with the required fixings. The finishing materials such as beading, scrim tape, plaster, and paint and can then be applied to complete the wall.
