  • Are aluminium doors better than upvc?
    Both aluminium doors and uPVC doors come with their own advantages and disadvantages. Aluminium is an incredibly strong material that allows you to have larger glass panels in your door as it is capable of carrying more weight. It also offers a more modern and sleek look. By contrast, although uPVC is still strong, its key selling point is that it's incredibly sustainable - it has a much lower energy demand compared to other materials, and thus impacts the environment less. uPVC is also popular for its effective insulation properties. Whichever material you choose, True Window & Glass offer fantastic deals on both types of door.
  • How does double glazing improve energy efficiency?
    One of the biggest benefits of our energy-efficient double glazing service is that it significantly reduces any heat loss from your home. Thanks to double glazing’s insulation properties, you can maintain a comfortable temperature in your home without having to keep the heating on constantly, which in turn will bring down the cost of your energy bills. Lower energy consumption also means less emissions, making double glazed doors and windows a more eco-friendly alternative for your property.
  • How to adjust aluminium bi fold doors?
    Your aluminium bi fold doors will need to be occasionally adjusted as part of a maintenance routine. Even when your doors are installed flawlessly by a professional, over time they can still fall out of alignment. This can happen as a result of bad weather or natural shifts in your home’s structure, but as a result your doors will cease to function properly, for example, they won’t completely shut or will slide on their hinges without catching or stalling. You will need to make adjustments to prevent this from happening, including: ● Assessing the leading door ● Adjusting to the left or right ● Adjusting the height If you are struggling to adjust your aluminium bi fold doors yourself, our experts will be more than happy to help.
  • When do upvc windows need repairing?
    Although uPVC windows have a pretty long lifespan, it will sometimes be the case that they’ll need to be repaired. Some common issues include: ● Condensation / misted glass ● Cracked or broken glass ● Water leaking through the window ● Damaged window frame ● Difficulty opening, closing or locking window Whilst all of these issues won’t require you to have a full window replacement, it’s nonetheless important that you seek the assistance of a window specialist to have it fixed in a timely manner. This way you will avoid a minor repair job turning into something much larger. If you need fast uPVC window repairs, we are available for 24/7 callouts.
  • Does double glazing need replacing?
    On average, double glazing windows should last 20 years at minimum. If your double glazing is old, not functioning properly or has suffered from forced entry, it could be time for a replacement.

  • How good are modern aluminium windows?
    Chic and understated, it's no surprise that modern aluminium windows are a popular choice for new properties.

  • What are aluminium sash windows?
    The term ‘sash window’ refers to any window that doesn’t open on a hinge; there is no outward swing. Instead, sash windows are opened by sliding vertically or horizontally. Most sliding sash windows are made up of two sashes, both of which fit into a frame with one in front of the other. Both sashes are fitted into vertical grooves, and are counterbalanced by weights connected with a sash cord hidden in the frame. Sash windows are not only easy to open, but will also remain in the position you set them in thanks to the perfectly balanced weights. Opting for aluminium sash windows only means that you will receive the added benefit of an exceptionally hard-wearing and sleek frame material.

  • How long do composite windows last?
    Composite windows are typically more durable than uPVC windows thanks to their hybrid properties, and in some cases can last as long as 40 years - marginally surpassing uPVC’s average lifespan of 25-35 years. This is down to the fact that composite windows combine the attractive look and robust insulation of a timber window with aluminium cladding for easier maintenance and durability. If you are in the market for a high-performance, visually appealing and long-lasting frame, composite windows could be what you’re looking for.
