REHAU has carried out indicative energy rating tests on its new REHAU-Heritage vertical slider and has achieved a ‘B’ and ‘C’ rating on two versions of the new window. This means the REHAU-Heritage will qualify for the coveted ‘Energy Saving Recommended’ mark.
The tests were carried out on two versions of the new window – one targeted at the public and new build sector with a standard bottom rail which achieved a B rating and one targeted at the retail and conservation market with a traditional mechanically jointed deep bottom rail which achieved a C.
The indicative testing is excellent news for REHAU customers fabricating in REHAU-Heritage because it means they will be able to have their windows formally assessed to the same standard and will be able to mark their windows with the ‘Energy Saving Recommended’ logo which is so familiar to consumers.
David Harmer, the Product Manager at REHAU responsible for the launch of REHAU-Heritage, says: “The REHAU-Heritage is almost invariably sold as a premium product to discerning homeowners and commercial specifiers. These are exactly the types of buyers for whom the energy ratings have the greatest significance so we know that these ratings have real potential to increase sales.”
The new REHAU-Heritage vertical slider has been rolled out to REHAU’s fabricator network during the first half of 2006 and made its first public appearance at the Chartered Institute of Housing exhibition in Harrogate in June.
Aesthetically, it features many of the elements from the original S719 Heritage but has additional benefits such as the deep bottom rail and low level silver gasketry for improved sight lines.
It also satisfies all the requirements of the commercial sector in terms of its extrusion in accordance with CEN A criteria, its ability to be fabricated to satisfy BS7412 and BS7950 and three chambered sash profiles which give increased thermal efficiency and weather performance.
