Corby Window Group and Ashton Windows are among the latest companies to achieve ‘A’ rated windows, both using Edgetech’s Super Spacer.

Corby has achieved a rating of 0(zero) with a double glazed window, with Ashton Windows following quickly with a triple glazed product achieving 4kWh/m2/yr.

Ashton’s ‘Thermatech Triple A Window’ is one of four ratings it has achieved. ‘We can now offer customers A, B or two options for C rated windows,’ says Brian Britch, Director of Ashton Windows. ‘Super Spacer is simply the best spacer technology on the market. Warm Edge has been the way forward for Ashton.

‘This is a great product for schools and airports – it’s not only energy efficient, it has good sound proofing qualities too. It’s a more saleable product that backs up our philosophy to offer the best products available.’

Corby achieved its A rating with sealed units from AG Glass. ‘Unusually, the units are krypton gas filled, and double glazed. They’re more cost-effective too,’ explains Corby’s Technical Services Manager Ross Walker. ‘We only started using Super Spacer units a few weeks ago but we’re already seeing the benefits. An A rated window has given us a lot of attention – and we intend to capitalise on it.’
