Large Sliding Doors

Internorm High-Performance Lift and Slide Doors

Internorm lift and slide sliding doors are like no other composite door system. Thermally, they have market-leading passive house U values, as low as 0.64, whilst also offering unparalleled over-sized architectural solutions.

With multiple configuration options, including moveable corners, frameless glass corners and structural bonded glass mullion details – this system has no limits! Find out more about our Studio XL range

Internorm’s high-performance doors range fits seamlessly into your property’s architecture with its varied styles and use of premium materials.

All-year-round performance

In warmer weather, you’ll be able to open up a room with ease thanks to the simple lift and slide mechanism and soft-close feature developed by Internorm.

The combination of materials allows you to have the best of both worlds; aluminium clad on the outside for security and warm timber or uPVC on the inside.

One of the features of our Internorm architectural glazing is SOLAR+. This coats the glass with a wafer-thin metal coating and is filled with an array of gasses to ensure no gaps remain between each pane of glass. When combined with Internorm’s gapless frames, this will leave you with a uniquely open living area that’s warm and safe all year round.

High efficiency and security

The benefit of large glass areas is that they bring more light into your home. Triple glazing ensures excellent thermal insulation – even on cloudy days. Should any breakages occur, our toughened glass panes protect from injuries – giving all-around peace of mind.

    Smart Home

    Our Internorm sliding doors can also be made Smart Home ready. As you are thinking about your new build, consider how you can integrate Smart Home technology into your windows, doors and light solutions.

    Our smart technology includes solar shading linked to your heating system, biometric doors, integrated blinds and automated lights.

    Solar shading is an external blinds system that lowers and rises depending on both the internal and external temperature. Its main purpose is to maintain a constant temperature in the house at all times. If it becomes too sunny outside, the blinds will lower. If it is too cold in the house, they will lift. They can also be controlled manually, which is good for security.
