The construction world has long been considered the norm in the premises of metal-plastic windows with double-glazed windows. Use such glazing is much more convenient than ordinary wooden windows. Metal-plastic designs are easily and quick enough, there is no need to paint them, and they serve for quite a long time.
The undoubted advantage of PVC glazing is its tightness. And the same feature is a certain problem. Keeping the room temperature, metal-plastic windows are also not allowed moisture and do not give the inflow of fresh air. Future from this problem will help the microwing function.
How can microbrowing can be arranged
The solution to the issue of access to the room has 3 classical solutions:
- Installation of special accessories;
- Device of the opening of the sash (comb);
- Installation of the supply air valve.
All solutions of micro-tension adjustment in plastic windows have their advantages and cons, while they all decide the main task - air ventilation in the room without drafts.
Having considered all the details, you can decide on the solution suitable for a specific situation.
Window fittings
Metal parts will provide window opening in different planes
When assembling the window in the groove on the profile, metal parts are installed, which provide different positions of opening and clamping the sash in the closed position. This system may include microwing mechanism. Ideally put it immediately at the time of assembly at the factory.
But if the window was mounted for a long time, it is quite possible to establish a mechanism in place. To do this, it is worth contacting the specialists. Any firm engaged in the repair of metal plastic structures provides this service.
The mechanism fixes the gap between the sash and the frame, sufficient for air intake (no more than 3 mm). It is usually opened by turning the handle for 45 degrees. Mechanisms of multistage fixation are found (rotation of the handle by 15, 45 and 60 degrees).
This is the optimal solution, but it will not be implemented independently.
