As part of the Government’s building regulations, all double glazing replacement windows must comply with window energy ratings (WERs) set by the British Fenestration Rating Council (BFRC). The label uses a rainbow system with a rating from A+ to G dependant on the energy efficiency levels of the double glazing. A+ is the most efficient and G is the least efficient.

Our PVCu/uPVC windows have earned the rating of A+ which indicates the thermal performance of the product. First Home Improvements is a BFRC-authorised installer and is audited to demonstrate the accuracy of energy efficiencies. The superior design and insulation makes all the difference to the performance of our PVCu/uPVC windows.

Energy efficiency

The advancement in energy efficient technology is definitely one of the 21st century’s technological advancements. With the need to reduce energy consumption the building materials industry is constantly looking for more eco-friendly materials who in turn improve housing quality, comfort and safety. It is in this sense in which construction companies started using PVC or polyvinyl chloride – an extremely versatile polymer. This material is so useful that is an essential component in several products we use daily like kitchen appliances, white goods, cars, in fact almost every home will have some element of uPVC in them.

We offer a wide range of uPVC windows, all supplied and fitted, including casement, vertical sash, tilt & turn, bow & bay windows. Contact us or Request a Quote to find our more about our full range.

What is uPVC or PVCu?

The flexibility of PVC is what led to the creation of uPVC or unplasticised polyvinyl chloride also known as rigid PVC, this is a special blend and unique combination created to use in the production of windows and doors. What makes uPVC special is that unlike other window materials, it does not have any BPA or phthalates which combined with its stability makes it safer than any other in the market. Nowadays the use of uPVC is becoming increasingly popular, being the material of choice of new constructions across the world, so much so that it accounts for more than half of the windows produced in UK and European Union, with it being introduced to other countries across the world.

uPVC is most popular in the windows market, but it is also used to make frames and sills, cladding, fascia and plumbing materials like pipes and guttering. Its first appearance as a construction material came with the creation of the uPVC windows in the UK, in the mid 1970’s. At first they were wanted for the lightness of the material, but as they started to use them many other benefits became apparent; like the fact that they are great thermal insulators, reduce noise and are extremely aesthetically pleasing.

Replacement windows and their benefits

The first benefit is that uPVC windows require a lot less maintenance than regular replacement windows with wood or metal frames, besides being easily cleaned with water and detergent and being less prone to grease marks, this window type doesn’t need any sealing or painting, which means after it has been installed you never have to give it another thought. Another advantage is that due to the nature of the material, uPVC windows are extremely tough and resistant, as mentioned before uPVC have been used in water and sewer pipes for several decades, this means that it is a strong and durable material that can handle extreme amounts of pressure and weight, which makes this window practically unbreakable. Good uPVC windows are ultraviolet ray resistant, which means that it won’t fade under a hard bright sun. It is also corrosion resistant which means it will never erode or rot maintaining its flawless appearance despite harsh weather and years of use.

Heat and insulation advantages

The next benefit of uPVC windows is that they bring thermal comfort to your home or business. uPVC is a very low conductor which means that it does not transmit energy well from one point to the other; this combined with a tight seal makes uPVC windows the best choice for energy efficient homes and buildings. Since PVC does not conduct heat it does not transmit the warmth inside to the outside, it also does not transmit outside heat inside. In Winter, metal or wood replacement windows accounts for the loss of 15 time more heat than houses that use uPVC windows, and in the Summer they account for the gain of 25% of the heat. Furthermore, double glazing uPVC windows improve thermal comfort and resistance by over 90%, this is due to the air pocket that is created between the first and second glass panes, this provides a barrier that helps insulate the space so regulating the interior temperature and keeping the weather outside at bay.

Multi-directional openings

uPVC windows can be manufactured so that they can be opened in any direction, this helps with cross ventilation, it also helps in the creation of natural wind currents that help cool down the home in a completely energy efficient manner. The fact that they can tilt and turn also makes them adaptable to different types of windows and makes them space efficient. Furthermore, their light designed and opening mechanism allows for any type of curtains to block in outside light.

Noise insulation

Another benefit of replacement windows using uPVC is that they are effective noise insulators. Outside noise is always an unwanted disturbance, generally for order to create effective noise barriers, there is the need for great mass, density and low resonance capacity in order to either muffle or reflect the noise. In order to stop noise from travelling in, the noise source needs to be interrupted by a material with excellent acoustic performance, the right amount of density which allows it to withstand traffic exposure and weather erosion. Even though it sounds like a simple feat finding the right noise insulating materials can be extremely complicated when meeting the requirements of a window, see through, light, small width and aesthetically pleasing material.

Since uPVC windows are created by welded profiles they have a multiple chamber structure which decreases its noise and heat conducting abilities by up to 70%. These factors combined with the flexibility and endurance of the material are capable of creating a durable and light window with the surprising capacity of acoustic insulation, as a result of its noise reflective capacities. The use of double glazing (two panes of glass) effectively reduces noise up to 35 dB, which improves your sleeping habit, enhances concentration and increases the value of your property.
