Patio doors connect the interior of your home with the garden or balcony. Large glass surfaces are usually installed to allow as much light as possible into the living area and a clear view of nature. Patio doors visually expand the living space and their large glass surfaces create a bright, friendly atmosphere.

As one of the best door and window manufacturers in the country, Grandsea offers you a wide range of configuration options. Not only can you choose between different sizes and materials, but you can also specify different opening types and colors. When buying a patio door, the appearance cannot be ignored - our doors are truly decorative. Match the colors to your personal taste and furniture. White, brown and grey are just three examples of the colors in our product range.

Although patio doors usually have very large glass surfaces, today they are no longer a problem in terms of energy consumption. Grandsea can use modern double or triple glazing during the manufacturing process, which prevents heat from escaping to the outside.

tilt and turn patio doors

Tilt and turn patio doors are designed to slide open. Therefore, these patio doors require almost no additional space to open. That is why they are only available as bi-element or in combination with several components. Parallel sliding doors and tilting doors offer a tilting function in addition to the sliding function. The tilting function allows you to have ventilation even on rainy days.

Folding sliding doors can also be used as patio doors. Folding sliding doors consist of different glass elements and are connected to each other via joints. The function is similar to that of an accordion. When opened, these wing elements slide into each other, without columns or side panels getting in the way. Due to their design, folding sliding doors are particularly suitable for wide patio fronts.

Which is the best material for patio doors?

Similar to windows, there are different materials to choose from when buying patio doors. They all have their own advantages and disadvantages: this summary will help you decide which material to choose.

uPVC
uPVC is suitable for doors and windows because it is very weather-resistant. Rain and cold do not damage the material. In addition, uPVC has very good thermal insulation, which is particularly advantageous when buying patio doors. The service life is long, and this material requires almost no care and remains stable even after many years. You can also buy other types of uPVC windows from us to match your patio door design.

Aluminum

Aluminum impresses with its outstanding sturdiness. This material is absolutely weather-resistant and durable, which is particularly suitable when buying patio doors. It requires almost no care and is considered very stable. In addition, the noise protection of aluminum is also high. Usually, the chic look is convincing and is especially effective on large patio doors.

Aluminum clad wood

When buying patio doors and windows, we also offer the choice of combined materials. These windows are aluminum windows covered by a wooden frame. This increases weather resistance, lifespan and security. At the same time, your care workload is reduced.

Additional features on patio doors for increased comfort and security

Insects bother us, especially on warm summer nights. Fly screens on patio doors reliably keep out the little pests. Whether it's a fixed tension frame, a movable swivel element or a movable roller blind: Investing in insect protection on patio doors can significantly improve your quality of life.

Direct sunlight in the summer can cause overheating in your living space. Sunscreens mounted on the outside of the patio door provide relief and also prevent prying eyes. Manual or motor drive is up to your personal preference.

Anti-theft devices on patio doors deter potential thieves. If they still try to break into your living space, security accessories with mushroom locks offer better protection than conventional accessories. Laminated safety glass (VSG) is also part of the anti-theft protection. The glass panes are securely connected to each other by a viscoelastic film. If the glass breaks, the components continue to form a stable unit, making it more difficult for thieves to access.

Lockable handles prevent unauthorized opening of the patio door if the frame is drilled from the outside. Each of the above measures ensures increased protection against theft. Combined, they are an almost insurmountable obstacle for thieves.
