Duct Slab Plus

For the thermal and acoustic insulation of ductwork in heating, ventilating and air-conditioning systems

Description

Duct Slab Plus is a strong, rigid slab of noncombustible, glass mineral wool with a bright class ‘O’ reinforced aluminium foil facing on one side.

The facing provides a bright, washable surface and a high level of vapour resistance.

Application

Duct Slab Plus is used for the thermal and acoustic insulation of ductwork in heating, ventilating and air-conditioning systems. It is also used for the general insulation of square or rectangular ducts and equipment and is suitable for insulating cold water storage and feed and expansion tanks.

Duct Slab Plus is particularly suitable for the thermal and acoustic insulation of square or rectangular ducts and equipment operating up to 230°C. In combination with suitable cladding, it provides an excellent basis for noise breakout treatment from ductwork.

Environmental

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.

Duct Slab Plus is free from CFCs, HCFCs and any other material with ozone depletion potential in their manufacture and content and represent no known threat to the environment.

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

Handling and Storage

Duct Slab Plus is easy to handle and install, being lightweight and easily cut to size.

Duct Slab Plus is supplied in polythene packs which are designed for short term protection only. For longer term protection on site, the product should either be stored indoors, or under cover and off the ground. Installation instructions are on every pack.

Duct Slab Plus should not be left permanently exposed to the elements.
