50mm Foil Faced Two Sides Rockwool RW4 is used to prevent the spread of flames, heat, smoke and fire through concealed spaces in buildings, a rigid class A1 non-combustible resin bonded insulation slab.

Rockwool RW4 Foil Faced 2 Sides Slab 50mm x 600mm x 1200mm fire performance integrity is 240 minutes, and 60 minutes for the insulation core with a certified thermal conductivity of 0.034W/mK.

RW4 Foil Faced on Both Sides Insulation Slab is manufactured in 80kg density per m3, specially designed for use in soffits, floors, roofs at rafter level, partitions, ceilings, timber and steel frame walls.

Stone Wool Insulation Slab RW4 is classified as Class ‘0’ to Building Regulations and can be used in ceilings, floors and walls to help sectionalize rooms, reducing fire spread and damage.

RW4 Slabs work in two distinct ways to reduce noise, either by impeding the transmission of sound through an element of the structure or by absorption of sound at the surface.

The structure of the fibres in RW4 slabs make them ideal for use as a sound absorber with water repellent qualities of the insulation preventing moisture build up, damp and rot.

Rockwool RW4 insulation slabs are made from natural, sustainable and recyclable resources and can be easily cut and shaped with a large bladed knife or saw.

These thermal and acoustic insulation slabs are free of CFCs and HCFCs and will not encourage the growth of fungi, mould or bacteria.

50mm Foil Faced on Both Sides Rockwool RW4 A1 Insulation Slab Installation Guidelines:

 · Required tools: serrated insulation saw and tape measure.

 · Clean and prepare the area for installation.

 · Carry out a pre-work safety check, identifying any potential hazards such as ease of access, work heights, trip hazards, and electrical safety.

 · Check the construction ensuring it is structurally sound and free from defects such as corrosion, splitting, cracking and look for signs of leaks and moisture which can cause rot and mould.

 · Ventilate the area if possible and clear space to hold the insulation, if installing into floors below, or in a loft, use a kneel board and protective knee pads.

 · When installing overhead wear protective eyewear.

 · If installing into spaces higher up, out of reach, it is recommended this is done from a suitable structure such as scaffolding, rather than a step ladder, so that both hands can be used to safely fit the insulation.

 · Assemble tools such as an insulation saw, tape measure and PPE (personal protective equipment) such as gloves, long sleeves, mask and eye protection when working overhead.

 · Refer to the EURIMA health and safety guidelines for guidance on suitable PPE.

 · Using a tape measure, measure the internal aperture of the frame, rafter or joist you are fitting the insulation into.

 · Note that frame centre measurements (i.e. 400mm or 600mm) include the thickness of the stud or joist, and that they may not always be consistent.

 · It is best to measure the internal aperture accurately to ensure the best possible fit, particularly when installing into older structures.

 · Use an insulation saw, or knife with a serrated blade, for cutting the insulation to size.

 · Do not over cut the insulation.

 · Allow an extra 10mm on both dimensions (width and length) of the insulation, over and above the aperture dimensions.

 · The density and dimensional stability of Rockwool stone wool allows a tight friction fit.

 · It will not require pinning or fixings.

 · To install, simply push the slab in one side of the structure and let the insulation go so it tightly butts into the other side and holds in place.

 · Ensure there are no visible gaps, as this will negatively affect the installed performance.

 · To meet fire, acoustic and thermal regulations cavity barriers must be installed at the interface junction between the steel frame party wall with the external cavity wall.

 · If in doubt in any area, please call Rockwool prior to commencement of work.

 · The mechanical effect of fibres in contact with skin may cause temporary itching.

 · When working in an unventilated area, wear a disposable face mask.

 · Waste should be disposed of according to local regulations.

 · Rinse hands in cold water before washing.

 · Ventilate the working area if possible.

 · Wear goggles when working overhead.

 · Clean area using vacuum equipment.
