Thermal Floor Slabs

For the thermal insulation of concrete ground floors

Description

Thermal Floor Slab is a rigid, compression resistant, rock mineral wool slab specifically manufactured for the thermal insulation of concrete ground floors.

Thermal Floor Slab Plus has a higher compression resistance than Thermal Floor Slab.

Application

Both slabs are for the thermal insulation of concrete ground floors. Both products can be placed:

above a concrete floor to support either flooring grade chipboard or a screed
on a dpc and sand blinding, below a concrete ground bearing slab

Standards

Thermal Floor Slab and Thermal Floor Slab Plus are made from non-combustible inorganic rock wool, defined as mineral wool in BS 3533: 1981 and are manufactured to a Quality Assurance system which complies with BS EN ISO 9001:2000.

Durability

Thermal Floor Slab and Thermal Floor Slab Plus are rot proof, do not sustain vermin and will not encourage the growth of fungi, mould or bacteria, and are odourless and non-hygroscopic.

Environmental

Thermal Floor Slab and Thermal Floor Slab Plus are 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.

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.

Thermal Floor Slab and Thermal Floor Slab Plus' manufacture has a low impact on the environment and is classified as Zero ODP and Zero GWP.

Moisture Resistance

Thermal Floor Slab and Thermal Floor Slab Plus are non-wicking when tested in accordance with BS 2972: 1989 Section 12. When exposed to 90% relative humidity at 20°C both Thermal Floor Slab and Thermal Floor Slab Plus absorb less than 0.004% of moisture.

Thermal Floor Slab and Thermal Floor Slab Plus are water resistant but require a DPM to protect against ground moisture. A separating layer is often required in screeded applications.

Handling and Storage

Thermal Floor Slab and Thermal Floor Slab Plus are easy to handle and install, being lightweight and easy to cut to size.

Thermal Floor Slab and Thermal Floor Slab Plus are supplied in weatherproof Supakube packaging, on non-returnable wooden pallets. This makes them very easy to unload and ideal for outside storage which frees up internal stock space.
