Aluminium windows in Bristol, Bath, Wiltshire and Gloucestershire

Aluminium is an increasingly popular choice for UK windows. A popular choice for large scale commercial applications, it is now becoming equally popular in the new build residential sector. Durable and requiring only occasional cleaning, aluminium frames are extremely robust, making them the perfect choice for a range of properties.

Aluminium is extremely lightweight but also extremely strong, meaning aluminium window frames can support large areas of glass with minimal frame width. This helps to create expansive exterior views and increase natural light intake. Aluminium window frames can be powder coated in almost any colour imaginable. This versatility and integral strength has helped aluminium windows become a popular choice in the UK window market.

    uPVC windows are cost-effective, energy-efficient, and require less maintenance. However, they may not be as long-lasting as aluminium windows. On the other hand, aluminium windows are durable, weather-resistant, and offer superior strength. However, they are more expensive and may not be as energy-efficient as uPVC windows. Ultimately, the choice between these two types of windows will depend on your personal preferences and requirements.

    Which is cheaper uPVC or aluminium windows?

    Installing aluminium windows is always more expensive than uPVC (on a like for like basis) because of higher material and manufacturing costs. But, in the long term, aluminium can prove very cost-effective because it’s a more robust material than uPVC.

    We are delighted with the windows, and have already been complimented by our neighbours on the upgrade.

    Tyler and Paul were very professional and showed good initiative for the inevitable adjustments that needed to be made. They were particularly considerate of our house, it’s character and our pets! Please pass on our thanks and comments as appropriate.


    We are delighted with the windows. As you know we were concerned that they would look different and more “clunky” but really you can’t tell the difference except that the new ones are not falling apart!!! The guys who did the fitting were also good. They were working in freezing fog, really cold but they carried on regardless, they were extremely tidy and cleared up after themselves.

    Excellent customer service, range of products and attention to detail. I honestly can’t rate them highly enough. They stepped in and came to the rescue after Salisbury glass cost us 8 months of time and 100k in increased material costs.

    These guys have been great to us. Helped us out at short notice after we were badly let down by another supplier. We asked for several minor details that were not standard (e.g. different locking mechanisms), and they were flexible and open to ideas. We ended up also commissioning our front door from them; it is super sturdy and beautiful. Always courteous, professional, and good payment terms.

    I was looking for a company that could deliver a bespoke pair of roof lights in the Alitherm system. Techniglaze offered the best price and worked with us to ensure the sizes were exactly right and conducted the sales process very professionally. The product is first class and we are exceptionally pleased with the service and product. I can highly recommend Techniglaze.
