    Why are bifold doors going out of fashion?

    At Direct Trade Windows, we can assure you that bifold doors are not out of fashion. However, you might perceive them this way if you already have them in your home. This perception could arise due to their relatively older design, which might show signs of aging, such as uPVC cracking and twisting, or the potential rusting of internal door hardware due to water exposure.

    Are aluminium bifold doors more expensive than uPVC?

    At Direct Trade Windows, we believe both options have their merits. While aluminium bifold doors may have a higher initial cost and potentially require additional investment to match the thermal efficiency of uPVC, they offer superior aesthetics, durability, and are perfect for those seeking a premium choice with a slightly higher budget.

    How good are aluminium bifold doors?

    Aluminium bifold doors boast exceptional strength and, when powder coated, can maintain their integrity for decades. Requiring minimal maintenance – primarily occasional cleaning – they outshine timber and uPVC counterparts in terms of resistance to warping caused by weather conditions. The inherent robustness of aluminium allows for slimmer frames, providing a broader and more expansive view through the doors.

    What are the benefits of steel-look bifold doors?

    Steel-look bifold doors provide exceptional outdoor connectivity and effective ventilation. They seamlessly blend the indoors with the outdoors, offering a sleek and modern aesthetic while maintaining slim sightlines.

    What variations are available for steel-look bifold doors?

    Direct Trade Windows offers energy-efficient steel-look bifold doors from Cortizo with options of two, three, four, and six sashes. These doors provide excellent U-values due to an integrated polyamide thermal break.

    We had been severely let down by a previous supplier, but when we turned to Direct Trade Windows for help, we hit the jackpot. Helping us to transform a residential development in Hersham, they supplied us with high-quality, ultra-slim Cortizo sliding doors, complete with the bespoke sliding options that we needed. Our requirements were very specific and not readily available on the market, but Direct Trade Windows really went the extra mile to help us out, coming through with quality products and excellent service. We will definitely be using their services again.

    Nothing but praise for this outfit. It was a pleasure to work with them. It was a nerve-wracking undertaking for us, the biggest single expense to fit three large window/french door combos in our extension, yet the team made it a relatively relaxing experience with their professionalism and good humour. Thank you all so much for everything you and the whole team have done to get from the initial sale (well done Hash!) to the fun visit we made to the workshop, to the design and its multiple iterations (thank you Taz!) and finally to the installation. Thoroughly recommended.

    Eloise Price - 2022

    Direct Trade recently replaced a large, faulty sky light. They said they’d take 3 hours, they took two. They did a fantastic job, there was absolutely NO dust or mess, at all. I was amazed… thought I’d be clearing up dust for days! I also didn’t need to get the recess re-plastered or painted – bonus!

    I highly recommend Direct Trade. They are a professional and friendly service delivering a high quality product.

    Vicky Steele - 2022

    I met with Taz at the warehouse to see some examples of the glazing and from the beginning he was extremely professional, personable and helpful. We ordered crittal style windows and doors, a Juliet door, 3 other windows and roof lights and every one of them was excellent quality, secure and well made. I highly recommend Taz and his team at Direct Trade Windows!
