Sliding Sash Windows Slough & Watford

A style that has been loved for generations. Sliding sash aluminium windows are a perfect blend of classic design and modern performance. Whether near to us in Slough or further afield, our windows meet and surpass contemporary standards while staying loyal to their traditional look.

It’s not just our high end products and outstanding quality of service that sets us apart. We cater to both supply only and supply & fit customers to meet a property’s needs. We can easily make any vision a reality with in-house manufacturing facilities, committed service engineers and installation teams.

Sliding sash windows are commonly used in heritage and conservation areas from Slough to Watford and beyond. Where Georgian and Victorian architecture is present, they can be a great addition. Whether they blend in or boldly stand out, their timeless design complements any style of property.

Whatever the property’s style, sliding sash windows offer a flush opening with no projection into or out of the building. This design helps to complement the signature period look that these windows offer—the perfect addition to highlight the beauty of any property.

    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.

    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!
