[RSDF-50]

Knauf Earthwool Rock Fibre Duct Slab For the Thermal and Acoustic Insulation of Square or Rectangular ducts

Description
Knauf Insulation Duct Slab is manufactured from non-combustible, inorganic rock mineral wool to give a strong slab of 45kg/cubic m nominal density with high thermal efficiency. It is supplied with a factory applied Bright Class ‘O’ reinforced aluminium foil facing.

Application
Knauf Insulation Duct Slab is for the thermal insulation of square and rectangular ductwork and equipment up to a temperature up to 850C.

Standards
Knauf Insulation Duct Slab is made from non-combustible, inorganic rock wool, defined as mineral wool in BS 3533:1981. It complies withBS 3958: Part 5 and with the requirements of BS 5422 and BS 5970. It is manufactured to a Quality Assurance system which complies with BS EN ISO 9001:2000.

Durability
Knauf Insulation Duct Slab is odourless, rot proof, non-hygroscopic, does not sustain vermin and will not encourage the growth of fungi, mould or bacteria.

Acoustic Performance
Knauf Insulation Duct Slab can be used for noise control of ductwork. The lightweight, fire safe and robust nature combined with excellent sound absorption characteristics make it an ideal choice for sound attenuation applications.

Operating Temperatures
Knauf Insulation Duct Slab can be used up to continuous operating temperatures of 850C and down to cryogenic temperatures provided that a 100% vapour barrier is maintained to prevent ingress of moisture vapour. The surface temperature of the facing should not exceed 80C.

Environmental
Knauf Insulation Duct Slab is free from CFCs, HCFCs and any other material with ozone depletion potential in its manufacture and content and represents no known threat to the environment.

ECOSE Technology
Knauf Insulation mineral wool products with ECOSE Technology benefit from a revolutionary, bio-based, formaldehyde-free binder technology, based on rapidly renewable materials, instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.
The technology has been developed for Knauf Insulation’s glass and rock mineral wool products, enhancing their environmental credentials without affecting the thermal, acoustic or fire performance. Insulation products made with ECOSE Technology contain no dye or artificial colours – the colour is completely natural.

Environmental
Knauf Insulation Duct Slab’s manufacture has a low impact on the environment and is classified as Zero ODP and Zero GWP.

Handling and Storage
Knauf Insulation Duct Slab is easy to handle and install, being lightweight and easily cut to size.
Knauf Insulation Duct Slab is supplied in polythene packs in Supakube pallets, which are designed for short term protection only.
For longer term protection on site, the product should be stored either indoors, or under cover and off the ground.
Knauf Insulation Duct Slab should not be left permanently exposed to the elements.

Performance

Thermal Performance
Knauf Insulation Duct Slab has a thermal conductivity of 0.033 W/mK at 10C.

Acoustic Performance
In combination with a suitable cladding, it provides an excellent basis for noise breakout treatment from ductwork.

Fire Performance
Knauf Insulation Duct Slab is classified as noncombustible to BS 476: Part 4: 1970 (1984), Class 1 Surface Spread of Flame to BS 476: Part 7: 1997 and Class ‘O’ to the Building Regulations.

Benefits
Excellent thermal and acoustic properties
Non-combustible
Easy to cut, handle and install

The Knauf Insulation range of technical insulation products has been specifically engineered to provide high levels of thermal, acoustic and fire protection insulation for pipes, ducts, equipment and vessels forming part of industrial process plant, or heating and ventilation systems.
Within the range, mineral wool products manufactured with ECOSE Technology are creating a new generation of insulation. ECOSE Technology is a revolutionary, new, formaldehyde free binder technology, based on rapidly renewable materials instead of petro-based chemicals. It reduces embodied energy and delivers superior environmental sustainability.
