Double glazed sealed units produced in-house keep all our costs down
Since 2004 Building Regulations have had to be extended to include period properties. Even back as far as the early nineties Sashpro (not a Ltd company then) was coming up with ways to improve the weather performance of period windows. Sash windows have gone further with major changes in order to provide for the demanding environmental challenges that must be met.
As one of the first ‘modern’ firms to address the preservation of sash windows in general, Sashpro has helped to develop a number of innovations that make it possible for the period sash window
to remain in existence and be accountable ecologically. We developed a weather proofing system that not only addressed the traditional synonymous combination of the words draughty and sash window, now thankfully rendered apart but we did it completely invisibly. In other words it’s one of those clever devices you’ll never see, so sash windows remain unaffected aesthetically. All good so far but not good enough for building regs.
Double glazing and traditional sash windows were never terms that sat happily together on the purists tongue however looking at the combination from the perspective that it was inevitable and thanks to a great Scottish inventor (whose needs might perhaps be considered greater up north!) Sashpro took a leap of faith and started to use the innovative Slim Sealed Unit. A low emissivity glass and the dense inert gas krypton, used instead of argon, along with ‘warm edge technology’ all allowed for the manufacture of super slim double glazing for sash windows, traditional timber casement windows and of course timber doors. We no produce our own sealed units which keeps costs considerably lower than most of our competitors. Great savings you can pass onto your customers to win the contract. We’ll provide help all along the way from product information, detailed specifications of works to final data sheets for your Building Control needs.
