Weber - Saint-Gobain

Llanwern High School - Newport, South Wales

Weber EWI has been used extensively in the construction of the new Llanwern High School, Newport, South Wales. Almost 2,500 m² of webertherm XM EWI has been installed by applicator M & P Contractors, Tonypandy, for award-winning main contractor Leadbitter, a subsidiary of Bouygues UK. The £30m project, designed by HLM, Cardiff, incorporates state-of-the-art facilities for the school's 1,450 pupils.

The BBA approved webertherm XM EWI system for Llanwern High School specified 110mm thick mineral fibre slab which was fixed to the substrate with adhesive and two supplementary fixings per board. The first 3mm application of weberend LAC, a polymer-modified, cement-based render, is applied followed by meshcloth reinforcement which is encapsulated in a further 3mm coat of weberend LAC to form a 6mm total coat. When dry the surface is primed with weber PR310, a pigmented primer. A decorative finish is achieved with weberplast TF150 for a fine textured, highly weather resistant surface.

Paul Davies of M & P Contractors was responsible for this extensive project. "We had up to eight staff on the EWI application during any one period and have considerable experience with the webertherm EWI systems. It has proven once again to be a very straight forward system to work with and the textured finish gives the buildings a striking, modern appearance which we are all very pleased with."

The lightweight webertherm XM EWI system, which is Energy Saving Trust recommended, provides excellent thermal insulation, with a very comfortable U-value of 0.28 W/m²K achieved in the construction of the new High School.

Peter Jenkins, head teacher at Llanwern High School said: "The bold colouring is a feature commented on by all our visitors and gives the building a smart, modern appearance. Having just completed our first full year the energy costs are well below even our most optimistic estimate and this clearly shows the quality of the design and the materials used in the construction."

The Llanwern High School has been designed to be at the heart of the community of Newport with facilities that are available to local business, sports clubs and community groups. For pupils the school provides a vibrant and stimulating learning environment. The excellent facilities of this brand new school includes a full photographic studio with processing laboratories; a fully equipped 'jam' pod; an incredible drama suite for skills development in everything from sound and lighting to stage craft, and a 3G football pitch which replaces the astro turf pitch.

Saint-Gobain Weber EWI systems are manufactured at facilities in Bedfordshire, Shropshire and County Antrim ensuring fast and efficient deliveries, guaranteed product consistency and reduced transportation miles. Together with market-leading environmental performance, reduced energy consumption and CO₂ emissions, these systems contribute towards the company's environmental policies. Saint-Gobain Weber's technical team offers a full U-value and condensation risk analysis service for new build and refurbishment projects.
