If you can feel a draft but your windows and vents are closed and your window pane and window frame are intact, you should check the rubber seals. These are located on the windows that open and they work by compressing and closing the gap while the window is shut, and springing back out once it’s open. Over the years that springiness can go and the rubber seal may just have flattened to the point where it’s no longer functioning correctly, and letting a draft in.
Worn door and window seals can lead to higher heating bills as hot air escapes and cold enter’s, you’ll be spending more to keep your house warm. So if you’re looking to save money and soft the annoying draft out, follow the below steps.
Tip: All window rubber seals are not the same. You’ll need to match the specific profile of the old seal to know which new rubber seal to buy. There are many different profiles for various types of frames and styles.
uPVC stands for Unplasticised Poly Vinyl Chloride. It is also known as vinyl windows. It’s a rigid material that is an extremely durable and long lasting form of PVC used within the building industry.
The main difference between PVC and uPVC is that uPVC does not contain phthalates or BPA. This means that it is a lot safer for transporting water and it also makes it fire-resistant.
uPVC is used for windows as it’s an ideal material for the frames. The rigid plastic has superior insulative qualities when compared to metal or wood.
Aluminium is stronger than uPVC which makes them a popular choice for windows that need a slimmer appearance and large glass pane. That means that aluminium windows can have a slimmer appearance, and a larger glass surface area due to the strength of the frames. However, uPVC performs better with it’s insulative properties.
