Knauf Warm Wall ewi systems enhance new buildings

An increasing number of designers are responding to the ability to maximise floor space, reduce CO2 emissions, provide exceptional thermal performance and aesthetic appeal by specifying Knauf’s Warm Wall external wall insulation systems.

The diversity of applications, from commercial, healthcare and education buildings to energy-efficient new home designs, is matched by the breadth of the company’s product offering, with different systems available to match key specification criteria.

Warm Wall Basis provides a cost-effective solution where economy is the main criterion; Warm Wall Energy is a similar system with additional features that eliminate the risk of cold bridging. Warm Wall Plus provides exceptional fire protection and Warm Wall Cavity Rail a system to meet NHBC criteria for framed structures.

Each is a multi-layered system comprising base-coats, a reinforcing mesh, primer and a render topcoat over an insulation core. Depending on the system chosen, the insulant can be expanded polystyrene, with either flush or tongued and grooved edges, or mineral fibre.

Each option is available in a variety of thicknesses to meet thermal performance requirements. Depending on the specification, Warm Wall systems can achieve U-values as low as 0.15 W/m²K.

Every element has been developed to complement its neighbours to create homogenous systems that are simple to install, effective in performance and low maintenance. The range of finishes includes acrylic, mineral, silicon or marble-based through-coloured renders which are available in a variety of grain sizes and over 500 colour variants from the company’s Colour Concept range.

Warm Wall systems can be applied to virtually any substrate and to timber or steel-framed structures. They are complete insulating façade systems and include a wide range of associated components including system fixings, starter tracks, boards for plinths and fire breaks, coated EPS profiles, joint sealant strips, render beads and trims.
