About Us

Market-Leading Aluminium Patio Doors

Stay Warm, 24-7

Stop heat from escaping by asking Direct Trade Windows to install brand new sliding doors at your home in Reading. A polyamide strip or bridge will be included with your double glazing, preventing the possibility of cold transfer and stopping your property from getting too cold. You’ll be able to enjoy reduced overall U-values and the size of your energy bills will decrease in direct tandem. From an environmental perspective, your sliding doors will also reduce the size of your carbon footprint.

Fine-Tune Your Design

Which configuration would you like for your new aluminium sliding doors? We can discuss a range of options with you when you call us. 1-6 panels can be included, and your double glazing can be manufactured in many different sizes. If you like the look of Visoglide Plus doors, you can ask the Direct Trade Windows team to fit them as lift and slide or in an inside sliding format. Whatever your choice is, complete your patio doors with a colour – and accessories of – your choice.

No Swing Arc Needed

Sliding doors are similar to bi-fold doors, in that they operate along a vertical track and open almost as wide as a home’s threshold. The key difference is that a sliding patio door does not require a swing arc to open, which means your double glazing won’t overlap into your room space. This mean that you’ll be able to place furniture and other household items close to the periphery of your living area – but without worrying about them being knocked or damaged when opening your doors.

Fantastic Security

Keep your home in Reading safer from intruders. Our slimline sliding doors don’t just look impressive, they excel at stopping would-be burglars from gaining access in almost all cases. Because your double glazing will be made from aluminium, it’ll be that much stronger. The inclusion of a multi-point locking mechanism will further improve your home security, because the locks are built into the frames. Find out more by calling or emailing the Direct Trade Windows team for advice today.

    Check Out Our Google Reviews

    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.

    Park Lane Developments

    2022

    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!
