Discover the specifications of our Aluminium Medium Duty Sliding Window and the customisation options available!

Thermally Broken – A thermally broken frame features an insulated barrier between the interior and exterior materials, significantly reducing heat transfer. This enhances energy efficiency and helps maintain a consistent indoor temperature.

Double Glazing – Double glazing uses two panes of glass separated by a spacer to improve insulation, reduce noise, and enhance energy efficiency.

Multiple Configurations – Both panes slide by default, but you can also choose to have one sliding or opt for our Bi-Parting option.

Security & Locking – An extra layer of security has been added with the built-in lock handle, providing a hassle-free process for security.

Fully Customisable – All windows can be coloured any RAL colour or have additional handles, locks, and even integrated blinds within the glass. They can also come with additional panels on any side of the window — please specify for more info.

ADDITIONAL PANELS

Found Next Doors Ltd through Google & they had excellent reviews so gave them a try, & they were excellent from start to finish. After sending them a few photo`s & short video of the door problem, Alice in the office gave me a quote with a minimum & maximum price including labour & travel, so we knew exactly how much the cost would be if the door needed any replacement parts. After a deposit was transferred, Next Doors Ltd emailed with a slot at 24 hours later for the works, & the engineer texted me in the morning with an ETA on site. The door had the necessary work done & the whole job was completed in 90 minutes. This is the second time we have used Next Doors Ltd, & now we have a properly functioning front door to our restaurant. We would definitely use Next Doors again, & also recommend them to anyone else, absolutely first class. Fino Restaurant Bognor Regis PO22 6AA.
