Product Description

ROCKWOOL stone wool does not burn and according to the official test classification is assumed to make no contribution to fire growth. Rockwool Roll insulation is semi-perforated – guiding the user to accurate cut widths of 400 mm, 600 mm or 1200 mm from one product.

Rockwool Roll is a medium density multi-use insulation mat. This versatile Insulation Roll is suitable for thermal insulation of roof spaces in domestic, commercial and industrial buildings. It is also useful for improving the acoustic performance of suspended ceilings. The Rockwool Insulation is a multi application insulation for domestic & commercial applications. It has a ‘K Value’ of 0.044 w/mk and is suitable for roof spaces in all types of building or to overlay ceiling tiles in suspended ceilings. This product is also fire resistant.

Rockwool Roll Insulation key features:

  • Multi-application product
  • Rockwool Roll is very light and easy to handle

Standards & Approvals
Rockwool Roll conforms to BS EN 13162:2001 ‘Specification for factory-made mineral wool products’.

Performance and properties

Fire Classification
Rockwool Roll achieves a reaction to fire classification of A1 as defined in BS EN 13501-1.

Acoustic
The incorporation of Rockwool Roll within suitably designed constructions can provide improved levels of sound reduction.

Compatibility
Rockwool will not react with any metal components in the loft, nor will it cause loss of plasticiser from PVC cables and pipes (see also the note on electrical cables opposite).

Watertanks
Insulation should not be placed directly under the cold water tank. Where access is required to water tanks etc, supports should be provided for a raised walkway.

Loft hatches
To preserve continuity of insulation, covers to loft hatches should be insulated with a minimum 100 mm thickness of Rockwool Roll. Double-sided adhesive tape may be used to hold the insulation in place.

Electrical cables
The IEE Wiring Regulations, 16th edition, British Standard BS 7671: 2001 and the Electricians’ Handbook (latest edition)
give guidance on the correction factors to be applied in down-rating cables according to situation, and each case should be separately calculated. Where possible, all cables should be lifted free of the insulation.

Handling and storage
Rockwool Roll is very light and easy to handle. It is supplied compressed in polyethylene wrappings which provide short term protection. For long term protection the roll must be stored indoors or under a waterproof covering.

Environment
Rockwool insulation relies on entrapped air for its thermal properties; air is not a VOC and it does not have Global Warming Potential (GWP) or Ozone Depleting Potential (ODP).

Thermal performance and U values

Thermal application
Thermal Performance
Rockwool Roll has a thermal conductivity (k value) of 0.044W/mK.

Installation
Part L: 2006 edition requires new pitched roofs with loft spaces to achieve U values between 0.16 and 0.11W/m2K.

To meet this thermal performance and minimize heat loss through the timbers, Rockwool Roll should be cross-layered
between and over the ceiling joists. The first layer (generally of 100 mm thickness) is rolled between the ceiling joists, which are normally spaced at 400 mm or 600 mm centres.

A second layer of Rockwool Roll (e.g. 170 mm thick) is then cross-layered to cover the first layer of insulation and the ceiling joists (see fig 1).

If upgrading loft insulation, check to see if existing insulation between joists is tightly butt jointed to sides of timber. If not, remove and replace as above. If the existing insulation is in good condition, cross-layer this with a minimum of 170 mm Rockwool Roll.

U values
100mm Rockwool Roll between joists (with the additional thickness of Rockwool Roll laid over joists shown in table
below).

Current HSE ‘CHIP’ Regulations and EU directive 97/69/EC confirm the safety of Rockwool mineral wool; Rockwool fibres are not classified as a possible human carcinogen. The maximum exposure limit for mineral wool is 5mg/m3, 8 hour time-weighted average.

Exceptional Goods:

Some building materials are extremely bulky and not practical to deliver outside Co. Sligo e.g. concrete blocks, tonne bags of sand or gravel or some lengths of timber. We have highlighted where this is the case in bold red writing. If you do order these products we will contact you to see if you want to pay an additional delivery charge or if you wish to cancel the order. Please do not take offence to this as some bulky goods may cost much more to deliver than the value of the goods. We are based in Sligo so can offer a local delivery service in this area using our own vehicles.

If there is a forklift or teleporter available onsite, we would appreciate if you could tell us in advance by filling out the special delivery notes when completing the order.
