A window is a window, right? You can open and shut it (if it’s fitted well, of course) you can keep the heat in and the weather out with it and – surprise – you can also look through it. If it’s doing those three jobs, then it’s doing a decent job. Isn’t it?
That might be the theory, but the reality is very different. Especially now that we require our windows to do a whole lot more than just look pretty. Windows have become the first line of defence against ever-increasing energy bills, and a poorly designed or energy-inefficient window will lose you money over the long term.
How can you tell if a window is good quality?
There is also durability. When uPVC windows first appeared on the market some 40 years ago there was an understandable backlash against these new pretenders. The window frames were often flimsy, fitted poorly and could barely stand up to the weather. No wonder double glazing firms got a bad rap in the 1980s.
But that was then. Today, uPVC casement and sash windows are way better all round, proving far more durable and with improved energy efficiency. In many cases they have become the go-to choice for UK homeowners, replacing even traditional timber.
uPVC windows are not created equal
Even so, some uPVC windows are better than others and while they may be pricier, you can guarantee that you won’t have to have them replaced within a decade. For example, let’s look at the popular Kömmerling range. Over the years the German firm has earned a well-deserved reputation for the build and energy-efficiency of its uPVC windows, edging into the position of being one of the world’s uPVC market leaders.
The question is: why? Well, for a start Kömmerling ’s five chambered profile system is more energy-efficient than the three-chambered designs from many of its competitors. This prevents thermal bridging, meaning that the thermal insulation of the finished window is exceptionally good. The glazing is also of utmost importance for low U-values, and contributes to a substantial saving on your heating bills. Modern uPVC windows are also incredibly low maintenance and easy top keep performing and looking their best for many years.
Environmentally-friendly and highly secure uPVC
It’s the case that uPVC can be recycled, and for several years now, all Kömmerling window and door profiles have been solely produced with calcium-zinc instead of lead. Not only is this kinder to the environment, it also makes uPVC profiles even more resistant to the most aggressive weather conditions.
Last, but certainly not least, Kömmerling windows offer a very high level of burglary protection – certainly not the case with other uPVC products on the market. The Kömmerling system offers windows and doors that are fitted with special glazing, burglar resistant frames and fittings, and additional locks or grilles. Customers can also choose from a range of individually-tailored security standards.
Choosing the right uPVC frames can be a complicated business, but at the Nottingham Window Company we’re here to help and have a range of quality uPVC windows from premium brands such as Kömmerling and Residence.
