Windows in older properties are often small and hardly allow any light in. Their insulation was poor, too much cold came into the house. That is different today.
Nowadays, even large windows can compete with an insulated facade. The positive result: “More healthy daylight, a more beautiful view of nature, rooms that are easy to use and the possibility of free solar heat gains”, explains Ulrich Tschorn, Managing Director of the Verband Fenster + Fassade (VFF).
Nothing is as exciting as nature itself – whether it is the unobstructed view over meadows and fields in rural areas or your own garden, often located in the densely built-up urban area, which pampers the eyes with its play of colours and the many animals that make a stop there in the course of a year. This natural cinema is only made possible by large window areas that are technically feasible today.
Heat less, enjoy more
Double or even better triple-glazed windows and balcony doors with thermal insulation glass today achieve very good insulation values throughout. Ice flowers are passé and cold feet near the window are a thing of the past. This increases living comfort and at the same time the heating system has to work much less, which reduces the traditionally annoying ancillary costs and frees up money for the finer things in life. This effect is supported by the free solar energy gains, which can be used perfectly, especially thanks to the low sun during the cold season.
Think about sun protection
However, in order to prevent it getting too warm in summer, suitable sun protection must be considered. Windows with solar control glazing or switchable glazing are also well suited. At the same time, the unhindered inflow of daylight has a health and concentration-promoting effect on the people in the house. Artificial light can be absent for longer – the house inhabitants feel more comfortable and homework or work at home or in the office is noticeably easier.
This also applies to the attic, which is no longer used by many homeowners as a storage room or drying room, but as a cosy retreat with plenty of daylight. “So you can see: the often little-noticed window can let in much more than just light and air. This is why large window areas should be taken into account when planning a new building or modernising an existing building,” concludes Tschorn.
