This client in Hoylake, Wirral, specifically wanted wanted
triple glazing to replace his old
double glazed windows and improve the thermal efficiency of his property. He had done his research into U values and wanted an honest, manufacturer who could achieve a low U value at an affordable price.
What is a U value?
A U value is a measurement of heat loss & the rate at which it is lost. Therefore, the lower the U value, the better & more thermally efficient the glazing will be. Typically a single glazed window would have a U value of 5.8; an old double glazed window (pre 2006) would be 2.8 – 3.0; current double glazing containing argon gas are around 1.2; and the newest triple glazing is 0.9-1.0.
Homeglaze Thermally Efficient Windows
We use Planitherm energy-efficient glass in all our new windows & could advise the client the U value would be 0.9 for his choice of uPVC triple glazed windows. He was also impressed that not only do we advise our clients, but we also install the windows ourselves – making sure the whole job is done to our very high standards.
Client Testimonial
We wanted to replace our old double glazed windows with a new thermally efficient triple glazed system. In a lot of instances, it's about way more than just choosing a more efficient piece of glass with an existing double glazed uPVC and expecting the window to miraculously improve how efficient it is. So many installers use the same plastic for triple as they do double, and then maintain there's only a marginal improvement in thermal efficiency that doesn't justify going to triple glazing. Sadly guys that's not true; that decision is more about them making a decent profit than delivering you a thermally efficient window. Find a better uPVC manufacturer, make sure you work with the right glass supplier and use the 'available to all' efficiency calculator to work out what U values you can achieve. Use as much glass and as few openings as possible and find an installer like Homeglaze who will work with you toward the goal you want to achieve. The moment I met Dave and realised that he would be installing the windows and not just selling me how great they were as a company, I knew they would be a company I could work with. I should add they weren't alone, there are some good companies out there and an awful lot of very poor ones, but there are very few who can both install a great system and at a reasonable cost. We went uPVC instead of timber because today there's very little single use plastic in a window system that lasts for 10-15 years. Despite some late changes and some finish details I changed at the last minute, Dave was superb, friendly and installed something that was both thermally efficient and aesthetically pleasing. I wouldn't hesitate to recommend them to anyone... The Deceuninck system with Planitherm Total+ gave us a 0.9 U value. We could've paid more than twice as much to get 0.8 or gone with double glazing at 1.1 or 1.2, but in the end, we made a good compromise decision on cost versus thermal efficiency giving us a future proofed window system at a cost we can live with...
