The existing building regulations and standards only seem to “think thermally”, forgetting about people and their need for a healthy life. At the beginning of the investment cycle and during its term, we are not able to check how important a properly designed and executed ventilation will be in the “thermally renovated” building.

A too one-sided approach to heat saving can therefore lead to a contradiction between quality of life and quality of health.  This problem should be noted by architects, installers and window manufacturers alike. By far the lowest costs are incurred when the vents are installed by the window manufacturers. Many of them already use vents in their products, and some are thinking about introducing rebate vents as a standard into their products. It is only a matter of time.

Certainly, their introduction into common construction practice will end the nightmare of “crying windows” and mould on the walls of apartments where modern window joinery is used. At the same time, housing cooperatives will save problems with grumbling users who, unaware of real problem source, will always direct their grievances to the owner or administrator of the building. We take into account the individual customer needs, therefore our air vents can be fitted to existing windows without damaging their structures and with window warranty intact.

There is still a race in progress which of the window joinery manufacturers will achieve a better air exchange rate.  Of course, all of this has to do with the economy. The more airtight our building is, the less money we spend on heating it by reducing heat loss. Therefore, everyone strives to make a thermos of their home.

For many years, the designers used to assume that fresh air enters the flats through the gaps between the window sash and the frame, between the frame and the wall, between the window pane and the wooden frame. The problems began when high-quality windows with sophisticated fittings and glass panes appeared on the market, which until recently had been unimaginable in terms of insulation.

It is a paradox that better materials are used to create buildings that are less human-friendly.  Research conducted in the West on the Sick Building Syndrome has confirmed that the main cause of illnesses among people living in such buildings is poor air quality.  If not properly ventilated, it is chemically and biologically contaminated to a catastrophic extent.

A significant reduction in the construction time of a house from 5-7 years in the 70s to 2-3 years at the end of the 90s resulted in the new building often not managing to get rid of the substances and chemical compounds contained in the materials used in its construction, as well as water present in the foundations, walls and ceilings.

Contrary to appearances, the situation deteriorates when we start a gas kitchen. During combustion, gas extracts oxygen from the air and releases carbon dioxide and water vapour into the environment, which are the natural products of its combustion.

This results in damp walls, misty windows, wet towels in the bathroom, wallpaper falling off, mould, stuffy air, malodour and unpleasant smells that permeate our clothes, as well as bad mood and general irritation caused by excess carbon dioxide and lack of oxygen in the surrounding air. We are often troubled by allergic hypersensitivity, which is also a result of the lack of proper ventilation in our homes.

In modern countries, which earlier than Poland realised the need to save energy and replace used windows with state-of-the-art, more airtight ones, the issues of healthy living and health protection are strongly emphasized.  Window air vents are commonly used there, the so-called compact window ventilators. They are located in the upper part of the window (in the frame), as a result of which fresh air enters the room, forcing the action of gravity ventilation and removing stale and damp air from the room.

1. optimum room air exchange
2. no draught under adverse weather conditions
3. compliance with all applicable laws, standards and regulations
4. excluded service errors by residents
5. excellent sound insulation
6. good thermal insulation
7. no need to use additional mounting parts in the window
8. very easy, non-intrusive installation, even in an already installed window
9. clear surface, no requirement to increase the cross-section of the frame member
10. total security during ventilation, both against the entry of insects, pollutants or precipitation and against burglary attempts
