Why It Pays UK Property Owners Dividends to Opt For Technologically Advanced Replacement Windows
We all know it makes sense to replace inefficient, outdated or inefficient existing windows, given the ever rising costs of electricity and gas, with the most affordable thermally efficient replacement windows in the UK marketplace.
However, the upfront costs can be a reason to keep putting off improving your property’s aesthetics, living environment and keep putting up with thermally inefficient out dated windows and doors. Given home buyers now expect a property to be fully double glazed (or a large reduction on the asking price), one should be pragmatic and if you don’t have the cash flow to replace all the windows and doors in one go, then do them in stages, starting with the ones in your living rooms and/or bedrooms first, so you get the maximum benefit from stage one of your home improvement investment.
Technological advances in the United Kingdom double glazing industry over the last 10 years or so have caused the first and second generations of replacement double glazing (which at the time was a significant improvement on single glazing) to be superseded by high performance “thermally broken” energy saving efficient windows, enabling far better energy ratings to be achieved.
For any double glazing manufacturers to achieve a decent window energy rating (i.e. C, B, A, A+ or A++) they need a frame that is thermally broken (i.e. where the outer pane and inner pane are separated, so that the cold on the outside cannot interfere with the warmth on the inside) and a high specification sealed unit with a warm edge spacer bar separating the inner and outer glass panes which is filled with an inert gas like Argon, which not only insulates, it helps with sound reduction too.
Recent technological advances now enable certain UPVC or PVCu products to obtain even greater energy ratings than “A”. Some companies use triple glazing to achieve better than an “A” rating, whereas others have opted to improve their double glazed frames, making them more robust as well as more thermally efficient in the process.
Triple glazing sealed units costs more than double glazed sealed units, simply because there are two warm edge spacer bars, rather than one, and three panes of glass rather than two. This means triple glazed units cost more to replace if they break down or crack than double glazed units, a factor worth noting if choosing between these two options.
Independent double glazing manufacturers and installers Hazlemere Window Company Ltd have been replacing windows in the UK for over 30 years. They have recently switched all their PVCu casement windows with side hung and top hung opening vents to A+ as standard. The outer window sash on the bespoke PVCu windows they supply and install now has six chambers increasing the thermal break between the inside and outside, as well as the robustness of the product. They also now offer a PVCu triple glazed window with a slimmer outer frame that has an A++ energy rating.
As it is now possible to have professionally fitted bespoke A+ energy rated double glazed windows installed for far less than A+ or A++ triple glazing, it makes better financial sense to invest in double glazed A+ windows. If the most thermally efficient windows on the planet are not well fitted, they won’t perform, so it is important to select an experienced installer you can trust to do a professional job on your property.
The dividends therefore, in terms of lower heating bills start immediately after having well fitted thermally broken energy saving windows installed. It therefore pays UK homeowners to have them all done, even if this work needs to be done phases for cash flow reasons.
