Among them we can choose various technical solutions and different types of mechanisms that allow you to open the sashes in different ways.

Types of balcony windows

There are many technical parameters, which can differ balcony windows. One of the most important issues when choosing is how to open them.

Sliding balcony windows

This is the most popular model of balcony windows currently used in houses and apartments. In it the balcony doors are slid on a rail along the entire sash. This solution allows you to save space and minimize the height of the threshold – which can be an advantage especially for children and the elderly. Moreover, such balcony doors will not close abruptly as a result of a draught

Double patio windows

Such a window, as the name suggests, consists of two sashes that open outward or inward. Usually, there is no mullion between them, and thus a huge advantage is the large space they open. Compared to standard patio doors, bi-fold doors allow you to create a more comfortable transition from your room to your balcony.

Three-sash balcony windows

This model consists of three sashes that open inward or outward. The three-sash window provides an even larger glazed surface than the two-sash window. The mullions placed between the sashes are usually movable, so they do not obstruct the passage to the outside.

Fold&Slide windows

In this model the window may have any number of sashes that can be folded like an accordion. In this way we have the possibility of creating an open space between the interior of the apartment and the balcony even along the length of the whole wall – this is both a practical and aesthetic advantage.

The wide choice makes it possible to match the appropriate model to our interior – depending on its size and purpose.
