Why buy uPVC Windows

The benefit of ordering DIY UPVC modern windows is that you can do it from the comfort of your home with a cup of tea and a biscuit, either on the phone speaking to one of our knowledgeable staff, or online using our informative website. Rather than sitting through a two-hour presentation from a shady- looking character, representing a large national windows and doors company even before measuring up and giving you the price.

Buying DIY windows allows you to build to your own specifications, through multiple options ranging from size to colour, right down to the locking system. With the online instant quote generator, you can see how much your window is going to cost you as you go through the options. This allows you to work to your own budget, and unlike a lot of our competitors, our prices are transparent.
5-chamber profile
Our UPVC windows use a 5-chamber 70mm UPVC profile. This has been proven to boost thermal efficiency by up to 16% compared to a 3-chamber equivalent, which can be found on the market. What does 5-chamber mean? 5-chambers refers to the number of different segments which make up the window profile. These segments act as an air trap, locking in small pockets of warm air, increasing the thermal efficiency of the profile and leading to lower energy bills.
Internally beaded
All of our UPVC windows are internally beaded. Having internal beading is perfect for anyone installing their new windows, as you can fit the 28mm sealed unit from inside your house. The alternative involves you having to balance the very heavy unit while you carefully ascend a ladder and then negotiate the beading into place before hammering it in place and securing it, all at height. Not only is this a far more dangerous, and complicated, option but you will be outside exposed to the elements.

Another benefit to having internally beaded windows is the added security. This may seem like a simple feature but there are still some companies which sell externally beaded windows. Having the beading on the inside restricts the possibility of easily removing them from the outside, taking the sealed unit from the window frame and allowing burglars access to your property and your valuables.
Our UPVC windows feature a multi-point locking system consisting of Espagnolette mushroom headed locks, which slide in different directions before sitting securely in metal keeps, making it harder for burglars to force your window open.

We also add anti-jemmy blocks to the inside of the UPVC window frame, placed in the opposite direction to that of the Espagnolette slide preventing burglars from trying to lever the locks out of place, gaining access to your property.

Our handles are push to open, which are safer in the event of a fire as the handles allow for quick opening, compared to windows featuring push to lock handles which take longer to unlock. Our push-to-open handles also feature key locking, locking the Espagnolette locks in place, allowing you to completely stop the window from opening and, adding to the overall security of the window.
28mm double glazing
Our 28mm sealed units consist of two 4mm panes of glass with a 20mm air gap incorporating a warm edge spacer bar, which is far more thermally efficient than the aluminium bars typically found in competitor’s windows. This is because aluminium is an efficient conductor of hot and cold temperatures which can contribute to a sealed unit breakdown. The 28mm sealed unit also has soundproofing benefits, perfect for anyone living on a main road or busy street.

In order to comply with part ‘L’ of building regulations, the glass we use in our sealed units features Planibel A (LOW-E) glass. This glass has a thin metal coating, designed to reflect the heat back in to the room whilst still allowing the sun’s heat to pass through.

The glazing we supply complies to BS EN1279-2. This means our sealed units have been independently tested for moisture absorption which can lead to sealed unit breakdowns such as steam or condensation build up inside the sealed unit.
100% virgin material
Our UPVC windows use 100% virgin plastic meaning your windows will be made from brand new plastic rather than old windows which have been melted down. The benefit of using virgin extruded plastic is that the profile will not discolour over long periods of time, making sure your white windows stay bright for many years to come.
