Rockwool RWA45 (ProRox SL920)

Rockwool RWA45

Rockwool RWA45 insulation is made of high-quality resin bonded slabs, which are available in a range of densities and thicknesses that are designed for excellent acoustic, thermal, and fire performance. RWA45 slabs can be used in a variety of building applications including acoustic and thermal insulation of partition walls, ceilings, floors, roofs, and general building applications which also include offshore platforms and ships.

The advantages of Rockwool RWA45 include:

• Excellent thermal, acoustic and fire insulation
• Water repellent
• Resists high temperatures
• Easy to handle and install
• Cost effective
• No maintenance
• Durable/ Long lasting
• Black or white tissues and aluminium foil facings available

The durability of Rockwool RWA45 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 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 the 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: RWA45 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 RWA45 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 performance of the insulation.

Thermal Performance: Rockwool is mineral wool that provides insulation to the building/ structure by reducing the airflow 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 RWA45.

Installation Guide For Rockwool RWA45

Before you begin:

Suggested tools when fitting RWA45 are a Serrated Insulation Saw and Tape Measure.

A face mask, goggles, and protective overalls are also recommended when installign insulation.

Preparing the area:

Clean and prepare the area for installation. Do a safety check and identify any potential hazards such as trip hazards and electrical safety. Check the construction has a reliable structure and free from damage such as splitting or cracking and check for any signs of leaks before application begins.

A kneel board is recommended for floor insulation. Scaffolding is recommended rather than a step ladder when installing into high spaces so that both hands can be used to it the insulation safely.

Measure & Cut:

Using a tape measure, measure the internal frame, rafter or joist you are fitting the slabs into. Note that frame centre measurements (i.e. 400mm or 600mm) may not always be consistent sizes, particularly in older buildings/ structures so make sure separate measures are done accurately to ensure the best fit of insulation.

When cutting the insulation to size using an insulation saw, or knife with a serrated blade. Be careful that you do not overcut the insulation as will no longer be usable in that particular frame. Allow an extra 10mm on both dimensions (width and length) of the insulation.

Applying Rockwool RWA45:

To install, simply push the slab into one side of the structure and let the insulation go so it tightly butts into the other side and holds in place. Make sure there are no visible gaps, as this will negatively affect the performance of the insulation and its purposes.
