In modern living, the patio door serves multiple functions. It defines the end of the living space yet opens it to the outdoors. Often the largest surface of a façade, it allows plenty of natural light in, creating bright rooms and a comfortable indoor environment.
Large glass areas add a spacious, elegant feel and offer unobstructed views of the outdoors. They extend living spaces onto the garden, balcony, or terrace, and allow solar heat gain, helping to reduce energy and heating costs.
However, large glass surfaces also pose a security risk, as patio and balcony doors are common entry points for intruders. That’s why choosing the right glazing – for both windows and patio doors – is especially important.
At windows24.com, you’ll find your patio door available in four different versions: as a parallel tilt-and-slide door, a Smart Slide door, a lift-and-slide door or a bifold door. Each of these types comes with its own set of features and can be configured in many ways. For the frame, for example, you can choose between uPVC, wood, uPVC-aluminium, or wood-aluminium combinations, and define the exact dimensions, design, and colour of your door to suit your preferences.
High-quality sliding doors also place specific demands on glazing. That is why it is crucial to explore the different types of glass thoroughly and find the solution that best fits your needs.
Thermal insulation plays a key role when choosing the right glazing for windows, balcony doors, and patio doors. Large glass fronts in particular are prone to heat loss, which not only impacts the environment but can also lead to significant long-term costs.
When installing a sliding door as a partition to a conservatory, thermal protection becomes even more important, as these spaces are often heavily heated.
So-called multi-pane insulating glass is available as double or triple glazing and offers excellent thermal insulation, with Ug-values ranging from 0.6 to 1.1 W/(m²K9.
When it comes to safety glass, we distinguish between single-pane glass and laminated safety glass. Single-pane glass is primarily used for household safety. If it breaks, it shatters into many small, blunt-edged pieces, significantly reducing the risk of injury. This effect is achieved through a special heat treatment of the glass.
Laminated safety glass, on the other hand, consists of two or more panes bonded together with a tear-resistant film. This type of glass offers effective protection against break-ins, which can be further enhanced with suitable frame materials and special fittings.
Fall-protection glazing is a special case, as it can be made from single-pane glass, laminated safety glass, or a combination of both. The specific requirements are defined by the Technical Rules for Fall-Protective Glazing (TRAV).
Not everyone is lucky enough to live in a quiet neighbourhood, and when the balcony or terrace faces the street, noise can quickly become a serious issue. For this reason, investing in a patio door with soundproof glazing is worthwhile, and this still allows natural light to enter the home. Lift-and-slide doors already offer good sound insulation thanks to their sturdier frame design, and depending on the noise level, this can be further improved with soundproof glass in classes 2 to 5.
Sound insulation class 2 glazing is now standard for windows and protects against noise up to 34 dB.
Sound insulation class 5 offers protection up to 49 dB, which may be necessary near airports, for example.
Soundproof glass from class 3 upwards also provides excellent thermal insulation – offering two benefits at a great price.
When it comes to privacy, the balcony and patio door glazing often needs to meet specific requirements depending on your living situation. If you want to avoid curtains or blinds to preserve natural light, you might still feel exposed. In this case, installing ornamental or patterned glass is a great alternative.
Ornamental glass is suitable for all types of balcony or patio doors – whether parallel tilt-and-slide doors, lift-and-slide doors, or folding sliding doors. Its decorative surface is achieved through a special rolling process.
With this type of glazing, the door not only reflects your personal style but also offers reliable protection from unwanted glances while still allowing plenty of natural light to enter.
Most types of glass can be easily used with all sliding doors – except for parallel tilt-and-slide doors. The movable sashes on these doors can only be built up to a certain size, as they would otherwise be too heavy for the tilt-and-turn function. When deciding on the type of glazing, it’s important to remember that the glass also contributes to the overall weight of the door – especially in the case of a patio door with triple glazing.
