Knauf Insulation, the UK's leading manufacturer of insulation products, has joined forces with Allan Roofing and regeneration and renewal specialist Michael Auckett Architects, to kit out one of Barratt Homes' latest developments.
Barratt Homes West London division has created over 300 residential units above the Blenheim Centre's Asda superstore in Hounslow. Knauf Insulation has supplied its Polyfoam Slimline System, consisting of 6,000m² of 120mm Polyfoam Roofboard Extra and Polyfoam Slimline Membrane, for the thermal insulation of the Blenheim Centre's protected membrane flat roof. The Polyfoam Slimline System has also been used under paving slabs on balcony and terrace areas, creating valuable outdoor space for residents and increasing the apartments' salability.
Due to the need for a slim, high strength and cost-effective insulation product, Knauf Insulation's industry-leading protected membrane system was ideal. Tested and certified by the British Board of Agrement (BBA), the Polyfoam Slimline System provides superior thermal performance and enables weight reduction. This means that Knauf Insulation's tough, durable Polyfoam Slimline System facilitates thinner insulation and reduced ballast load with no loss of performance.
Knauf Insulation's Polyfoam Roofboard is 100% ozone friendly extruded polystyrene rigid board, producing a thermally efficient and lightweight roof. Highly resistant to water absorption, it can be used above the waterproofing layer and thus is suitable for exposure to rainwater. Polyfoam Roofboard is highly resistant to compression, capable of handling both short and long-term static loads.
Knauf Insulation's Polyfoam Slimline Membrane is a high performance, non-woven polyethylene geotextile membrane for use in conjunction with the Polyfoam Roofboard. It improves the performance of protected membrane flat roofs by reducing the amount of rainwater flowing between the insulation and the waterproofing membrane. The usual impact on thermal performance by rainwater cooling is therefore vastly reduced, so by using the same thickness of Polyfoam Roofboard superior U-values can be achieved.
While the Polyfoam Slimline Membrane is highly resistant to the passage of water, it is vapour permeable, so moisture does not become trapped below and between the insulation .layer. As more drainage occurs above the insulation rather than below it, the floatation impact is vastly reduced, meaning even less ballast is required.
Keith Lewis, construction executive at Allan Roofing, explains that Knauf Insulation's Polyfoam Slimline System was the obvious choice for the Blenheim Centre: "We enjoy a long-standing relationship with Knauf Insulation. Aside from their products being industry-leading, on budget and readily available at short lead times, the service they provide is second to none."
Knauf Insulation's Andrew Tichy concludes: "With increasing thermal performance requirements, Knauf Insulation is proud to be at the forefront of recommending, manufacturing and supplying compliant insulation products. What sets us apart is the effort we put into building relationships with architects and contractors, and it's great that we have completed another project for Allan Roofing as a result."
