‘A’ Rated Windows From Sunrise Windows
Sunrise Windows will always use A rated windows when fitting new windows into your home or property.
Sunrise Windows has always insisted on using the finest materials available, for example:
- For the all-important spacer bars we now use a new thermal bar, which removes the chance of internal conductivity which can lead to condensation.
- For all our windows we use exceptional low emissivity glass such as Pilkington KS.
Although there are different specifications for different systems – the guidance below is typical for an “A” rated PVCu window:
Call us on 01752 339373 or our freephone number 08085 30 40 25
For an A rating, a window has to be manufactured slightly differently, we have to make sure that a special thermally efficient re-inforcement is inserted in the main chamber in the outer frame only, this is to enhance the thermal efficiency of the frame.
The Standard Glass Configuration for an “A” rated window is:
- Inner pane = High performance low emissivity glass such as PLANITHERM or Pilkington KS
- Cavity = Argon gas filled cavity
- Spacer bar = New Thermal spacer bar
- Outer pane = Low iron glass or standard glass
Also, the spacer bar (the bit around the edge which separates the glass) is no longer made using a silver aluminium bar – we now use a thermal bar or a “super-spacer” to stop thermal bridging at this point.
The most energy-efficient window glass available in the UK
Sunrise Windows use a high quality low emissivity glass, which is part of a new generation of energy saving window glass material, that uses advanced coatings to retain more internal warmth whilst capturing free energy from natural daylight. That means lower energy bills compared to standard windows.
Using the latest technology, low emissivity glass has a unique combination of metallic layers, which reﬂect heat back into the room, to keep heat within the building.
At the same time it maximises the amount of natural light coming in.
As more heat is retained, it means less is required to warm up the home to the desired ambient temperature, in turn lowering energy consumption.
I recommended ross to my son in law as they wear in need of new windows ross came out and priced up all the windows and so did others but ross came in at a very good price and a time scale to suit , ross got the job and a good job was carried out by his team and i am happy to say you can do mine . Thanks dave
Having used Ross recently to have some new windows and doors installed recently at a Buy to Let property of mine, I have to say it was rather refreshing experience. Ross turned up when he said he would, quoted for the works when he said he would at a competitive price and carried out the job when he said he would to a very high standard. His guys left the House in a very tidy state and the quality of the Job was so good, I would have no hesitation in recommending Ross to others and will certainly be doing so. Great Job, thanks Ross.
I’d like to thank Ross and his Staff at Sunrise Windows, after some severe weather conditions recently I spoke to Ross regarding a leak that my bay window had developed after moving in to the house 4 months ago. Ross promptly came out to my property and reviewed the problem, Ross explained what the issue was and the steps involved to resolve it. This put my mind at easy and arranged a suitable time to come back and repair the window seal. The whole process was painless and I will be using Ross and his team’s services again in the future to replace all the windows when the weather improves.
