Insulation manufacturer Celotex has launched Celotex SW3000, a direct render for external solid walls for both new build and refurbishment projects.

Celotex SW3000 is an external wall insulation (EWI) material featuring polyioscyurnate (PIR) insulation with coated glass tissue facers.  It has been designed to act as a direct render solution, enabling the render system to be directly applied onto the insulation with no requirement for separate batten systems or render boards. 

With a thermal performance as low as 0.026 W/mK, Celotex SW3000 also has a better thermal efficiency than many other insulation products that are used on EWI systems. This results in SW3000 being up to 50% thinner than many mineral fibre products which in turn reduces installation time and cost.

Celotex SW3000 carries moisture resistance properties, unlike mineral fibre and phenolic which can suffer from moisture penetration, leading to thermal degradation.

Available in a variety of thicknesses and a board size of 1200mm x 600mm, Celotex SW3000 is typically installed by mechanically fixing the boards to the walls and then applying the render system onto the boards.

‘Completing our range of refurbishment solutions for internal and external thermal upgrades, Celotex SW3000 can achieve Building Regulation targets for external solid walls with thinner solutions than many other insulation materials,’  said Celotex product manager Paul Evans. ‘The introduction of SW3000 proves that Celotex really does know insulation inside and out.’
