System 10 casements are extremely energy efficient. They are proven to help keep the warmth inside your home whilst keeping the cold out and any heat loss to a minimum - all this will help reduce your heating costs significantly. The cost saving made from reduced fuel bills outweigh the investment cost over the life expectancy of the window.
All System 10 windows supplied1 by us have a minimum energy rating of B, with the ability to upgrade them to A+6 and beyond by changing the specification of the energy efficient double glazed units, and are available in white, Cherrywood, Rosewood and Anthracite Grey.

Now the Technical bit
System 10 is a 3 chamber, category A profile, this means that the external walls of the profile are between 2.8mm - 3mm (in this case 3mm), compared to category B which is 2.5mm - 2.8mm and category C which is 2.2mm - 2.5mm and is extruded by the Veka UK Group in Burnley. The 3mm thick external walls makes the framework more sturdy than its category B and C counterparts. All our frames are reinforced with galvanised steel in accordance to the Veka technical manual.
For our window hinges we use the DGS Elite range of friction stays. DGS have been making friction stays in Melbourne, Derbyshire for over 30 years, in house testing is routinely carried out by DGS on all their ranges up to 20,000 cycles (equivalent to 100 years use) and performance is further endorsed by the British standards institute (BSI) and the police preferred Secured by Design scheme.
Our locking system is also provided by DGS, the Elite Twin Cam is a high security espagnolette locking system comprising of up-to 8 (4 opposable pairs) adjustable security cams. When operating the handle the cam pairs move in tandem towards each other pinching into the locking keep attached to the framework. This pinching method holds the opening sash tight in place eliminating the ability to 'jemmy' the sash open
