All windows (like all other products) have a lifespan, and old and outdated windows should be replaced. The obvious reason is the aesthetical one as old windows may not be aesthetically pleasing, but the functional part is even more important. As windows age, the material wears under external effects, and problems such as micro cracks in the glass or frame, worn down rubber seals etc start to form. These cracks and tears in the window insulation lead to the waste of energy, as hot air leaks from the inside, resulting in a fortune spent on energy bills. 

Some issues can be repaired or even prevented in the first place by the correct  windows maintenance.However when it’s finally time to replace the window, this is where we come in. With DK you have a wide choice of top quality windows which can come in a variety of shapes, sizes and materials. Weather you choose timber, aluminium, aluclad or uPVC, all these window types have their own qualities in regards to the functionality and aesthetics. 

In this Blog post we will be examining the benefits of choosing uPVC windows.

Why choose uPVC windows?

First of all let’s start with what these are and what are the differences compared to other materials. uPVC stands for Unplasticised Poly Vinyl Chloride and is a most commonly used window material out there today. This material has long been used in the building industry and it’s still used today mostly because of its rigidity and durability.

This material has been used for creating other construction items because of its durability, and a good example are sewage pipes. UPVC (which is also commonly known as vinyl) is a UV resistant, rot and corrosion resistant material, which makes it perfect for external uses. This is why this material is ideal for windows (and doors), and why it’s so commonly used today.


If you’re looking to save on the energy bill, look no further. UPVC is non conductive, which makes it a great insulator. When you take this frame and combine it with a good double or even triple glazed glass pane you get a great thermal insulator that will keep the temperature inside the house consistent resulting in less need for heating.

Acoustic insulation is another quality of uPVC windows, especially combined with double or triple glazing.


Security-wise, our windows come with multi-locking systems which makes your window safe and secured. In reality, it takes a lot of effort to break into a house with good windows.  With uPVC, you can be worry-free knowing your home is protected and secure.

Resistant and eco-friendly

uPVC as a material also has a good fire resistance rating. Living on an Island, means you’re close to the sea, and makes salt erosion a serious issue. Sea salt is carried by wind and this can really damage your window over time.

It’s also good to know that uPVC is a recyclable material that can be recycled up to 10 times. Once the window has reached the end of its lifespan it can be recycled and used for other products.

Mouldable and low maintenance

One of the best traits uPVC has as a material is its ability to be moulded into different shapes. This is also why it is really thankful for windows. UPVC windows can also be moulded to mimic other materials such as wood or aluminium, so you can have the traditional look of timber windows with a material that is much easier to maintain.

Speaking of maintenance, with uPVC there is next to none. You can just clean them easily with any window cleaner and water every once in a while and that’s it. 

As you can see uPVC has a lot of advantages, and it’s sure to be a long-lasting window at a good cost-benefit ratio. If you decide on uPVC windows contact us and we’ll find a perfect fit for your needs!
