How Our Windows Are Made

Have you ever wondered how the windows in your home were constructed? Many of the objects around us, we take for granted or don’t even really notice on a daily basis. Sometimes it’s fun (and educational) to look at something and find out how it came to be in your home. What is it made from, how was it put together and when were these processes first invented are all great questions we should be asking of everything around us. Especially if you have small children who ask a lot of questions!

A UPVC window doesn’t just appear in a window shape but is actually sections which are cut to size and joined together to make whatever window shape is required. The pieces are fused together by pushing the melted PVC through a precision die. Once cool, the portions are cut to length. The windows are then constructed using these measured pieces and are fixed into place by welding or the use of T-joint connectors. The plastic can be reinforced by adding aluminium or steel inside which gives the window frame extra strength. For Double Glazing in Gloucester, visit

UPVC is made from a substance called polyvinyl chloride polymer but it’s not effective for use in windows unless it has other things added to it. Stabilisers and additives are used to make the plastic fit for purpose and they act as heat and UV stabilisers. Depending on the final destination of the window, different stabilisers can be used. A window for a house will need different qualities than a window for a lorry, for example.

UPVC is one of the most resilient materials, offering a robust barrier to provide excellent safety and comes with top class insulating properties. It also offers good sound insulation so if you live near a busy road or love to play the trumpet on a Sunday morning then you should seriously consider having double glazed UPVC windows and doors installed.

Once you have the windows installed in your home, UPVC has a great low maintenance feature. However, you’ll want to keep the investment looking as good as possible for a long time and also to protect its durability. UPVC windows are very long-lasting and the only issues are likely to come from surface damage as with any material or common functional repairs such as new handles. Cosmetic damage could include things like scratches and dents for which kits can be purchased containing wax and touch-up pens to match any style of PVC.

Hardware damage can be as simple as repairing broken or damaged handles, hinges or locks. Replacement parts are easy to get hold of. The most common issue is the gearbox wearing down on a locking mechanism but this is an easy fix and that’s one of the great things about having UPVC windows. Hinges are also easily replaced as the design and manufacture of these windows is all about ease of use, simple to clean and straightforward to maintain in the long-term.
