Designing large windows – tips and solutions for sun protection

Large window fronts in the facade and skylights in the attic are almost part of the standard equipment of modern houses. Nobody wants to live in dark rooms these days and that is understandable for many reasons. Daylight has a direct impact on people’s physical and mental health. It not only brightens the mood, but also increases well-being and performance. The larger the window, the more open, brighter and more homely the room appears. Today we tell you what other advantages large windows bring and what you should still consider when designing them.

Large windows bring many advantages

Modern houses such as zero-energy and passive houses are not only convincing visually, but also in terms of energy efficiency. An excellent thermal insulation of the house walls and windows underlines this trend and guarantees an optimal use of energy. In the long run, this brings considerable savings and is kind to the environment. When planning modern passive houses Cardinal points the window arrangement so that the interiors can make optimal use of the sun’s rays and the incidence of light. In the north, large windows are hardly worthwhile, but in the south you can use the free solar energy as an additional heat source. Technically, the installation of a window front is also possible retrospectively in every house. If you want to replace an existing wall with large insulating windows, you have to apply for a building permit.

In the case of large windows, the use of triple insulating glazing or thermal insulation glazing is definitely recommended. Your advantages: low heat loss and great savings potential. These thermal insulation windows are made with triple glazing and also contain inert gas fillings in the spaces between them. When buying a window, the U-value (heat transfer coefficient) must be taken into account. The U-value indicates how much heat is released from the inside of the room through the window to the outside. The smaller the U, the better the insulating effect of the glazing. In contrast to old windows, new energy-saving windows have a significantly better U-value between 0.6 – 1.5 W / (m²K). When choosing new window glazing, you should definitely find out about the g-value. The g-value ranges from 0 to 1.0 and shows the permeability of the glazing for solar energy. The ideal window therefore has a high g-value and as low a value as possible.

Old and leaky windows in old buildings give off a lot of heating energy to the environment and increase heating costs, so one should consider possible imitation of insulation dimensions. Several alternatives for replacing old, single-glazed windows are available here. The compression tape, for example, is well suited for sealing the window frames, as it expands from 2 to 10 mm after it is attached and at least eliminates the effects of air locks. The comfort mainly depends on the window temperature. In order to save energy and to feel more comfortable near the window, the window panes should be well insulated. Cold protection films can be attached to the window from the inside and reflect the heat back into the room, whereby effective protection against the cold can be achieved.

Shading for large windows

A large window front should let light and warmth into the room, but also offer the possibility of darkening and privacy protection. What is desired in winter can quickly become too much in summer. If you are not completely sure about the selection, you can get advice from your specialist dealer. However, below we give you a few ideas for large windows.

It is not only possible to equip small windows with roller blinds. Even very large window fronts up to 4.5 m wide and 4 m high can be covered with a maxi blind. They are an attractive alternative to the classic curtain and can also become a decorative eye-catcher with photo printing. A practical solution would also be blinds that are made to measure and can therefore be perfectly adapted to any classic or modern window front. Structural requirements such as sloping ceilings and bay windows are also no problem.

Vertical blinds, also known as vertical blinds, are usually the first choice when furnishing offices, but they are now also finding their way into private rooms. Many kitchens and living rooms in modern houses, for example, offer plenty of daylight through large window fronts and direct access to the terrace or balcony. Thanks to their flexibility, lamellar curtains can be opened quickly to allow access to the outside. The incidence of light and the view to the outside can also be flexibly regulated.

Sliding curtains are a great design option, especially with wide window fronts. Panel curtains perfectly combine functional privacy and sun protection and creative room design. Sliding curtains are hung on trolleys in multiple curtain rails and offer glare protection exactly where it is needed. Up to five tracks can be guided one behind the other in the rail system. This results in great variants and combination options: transparent and opaque materials, single-colored and patterned lengths of fabric as well as entire window pictures with individual motifs. There are no limits for your creativity!
