Räum aluminium patio doors help to maximise space and optimise light

Räum aluminium patio doors are available as either a horizontal triple track sliding door or with an innovative lift and slide opening system. The horizontal sliding systems activates when the lock is engaged and slides effortlessly open. The lift and slide variation is activated once the handle is turned 180 degrees, enabling the whole sliding sash to be raised and slide smoothly along the track. Both systems are durable and energy efficient and suitable for a wide range of residential and commercial applications.

    Frequently asked questions

    What’s the difference between sliding doors and patio doors?

    A sliding glass door and a French patio door differ in their frame width. Sliding doors have narrower frames, allowing for more natural light, while French patio doors have wider frames which are a more traditional style that many homeowners prefer.

    Both types of doors have their own unique benefits and can be a great addition to any home depending on personal preference and specific needs.

    Is it better to have sliding or French doors?

    Sliding doors offer better security, ease of use and space-saving opportunities. Additionally, sliding glass doors are energy efficient due to their insulated frames and glass packs. French doors, on the other hand, allow for more ventilation, but they can have issues with space, mechanics and energy efficiency.
