Question 1

What does a patio door cost?

Accepted Answer

Patio doors are available in four different opening variants: as a Smart-Slide door, a tilt-and-slide door, a lift-and-slide door and a bifold sliding door. The price, therefore, depends primarily on which system you choose as well as on the preferred material. For example, a Smart-Slide door of uPVC is available from €1,357 , and a lift-slide door of the same material from €2,761. If, however, you decide on a lift-slide model made of wood, you can expect prices starting at €3,451.

Question 2

How can a patio door be secured?

Accepted Answer

It is worth investing in good security technology for patio doors, as they are still, along with windows at ground level, one of the most popular entry points for burglars. In our configurator, we offer numerous options to increase break-in protection. The right glazing (e.g., toughened or laminated safety glass or impact-resistant glazing) makes it more difficult to break the window. Multi-point security fittings (optionally up to resistance class RC 2 N) prevent the door from being levered open. If you would like to use the door as a back door at the same time, we also recommend a door gear with a profile cylinder.

Question 3

How big should a patio door be?

Accepted Answer

The ideal size of a patio door depends on many factors. A sliding door is usually used for large wall openings, while a classic French door is often more suitable for smaller openings. In addition to the type of door, the number of sashes also influences the dimensions. A guideline for a sash is 80 to 100 cm wide and approx. 200 cm high. However, you can always determine the size of your door individually on windows24.com. The minimum and maximum dimensions are displayed directly in the configurator, and should these not be sufficient, simply contact our customer service.

Question 4

What is the difference between a lift-and-slide door and a tilt-and-slide door?

Accepted Answer

The most obvious difference between the two doors is their opening type, which is already reflected in the respective name. On lift-and-slide doors, the sash is lifted slightly while opening and then conveniently slides to the side on rollers. This means that even very large and heavy sashes are possible. In addition, a lift-and-slide door can also be installed barrier-free, which is unfortunately not feasible with tilt-and-slide doors. These have the advantage that they offer a convenient tilt function for easy ventilation. To open the door fully, the movable sash slides along parallelly to the fixed element.

Question 5

When is a bi-folding door suitable?

Accepted Answer

Bi-folding doors are ideal for very wide glass surfaces. Thanks to their special construction, the door front can be opened completely if necessary. The greatest advantage of a bifold door, however, is that it can be opened in an extremely space-saving manner even with large opening widths. The individual sashes are simply folded together.

Question 6

Which glazing is recommended for patio doors?

Accepted Answer

The type of glazing you choose for your patio door depends largely on your personal requirements and wishes. To improve thermal insulation, for example, you can choose from a range of double and triple insulating glazing with a Ug value of up to 0.6 W/m²K. If you live near a main road or are exposed to other noise, we also recommend soundproof glazing up to class 5. And to improve break-in protection, we also offer laminated safety glass and break-through-resistant glazing.
