UPVC windows can be equipped with one of the three air vents currently available. In terms of price, uPVC window glazed-in air vents are the most affordable. Vertical air vents are somewhat more expensive. The most pricy are autonomous air vents for uPVC windows.
UPVC window and door air vent benefits
Air ventilation is necessary in all residential and office buildings in order to feel comfortable and avoid condensation. When you open the windows, stale and damp air is replaced by fresh and dry air from the outside. Therefore, ventilation not only brings in fresh air, but also helps to adjust the room temperatures. However, there are many drawbacks related to air ventilation by opening the windows: creation of draughts, the sudden drop in temperature (especially in cold months), the lack of security. Some uPVC windows include a night vent facility or micro-ventilation, which lets in very small amounts of air by opening the uPVC window slightly. However, night vents provide only limited ventilation and are vulnerable to burglars. Air vents offer a great alternative to traditional ways of air ventilation. Air vents operate without opening any windows, and so increase security. You can leave the air vent open even during the night or when you are away without any risk. Modern uPVC window air vents prevent draughts and provide constant and effective ventilation. In many cases, uPVC window air vents come with rain grilles and insect screens; some reduce noise from the outside and control the room temperature. The most up-to-date uPVC window air vents are autonomous; they have sensors that measure humidity or air pressure and adjust the air flow accordingly. Autonomous uPVC window air vents operate automatically; they open and close when necessary. Air vents for uPVC windows bring many benefits, so consider them for your new uPVC windows.
Window and door air vent types
Air vents come in several types which differ in their construction and the amount of air flow provided. Some of the most popular types include vertical air vents, glazed-in air vents, autonomous air vents and trickle vents.
Vertical air vents for uPVC windows have been popular in the region since the Soviet times and are often referred to as “soviet” air vents. They are mounted vertically along the left or the right side of the uPVC window. Glazed-in air vents are also known as horizontal uPVC window air vents. They are placed on the upper part of the uPVC window glazing, close to the window frame. They are not as wide as vertical air vents and thus the reduction of uPVC window glass is minimal. Autonomous or self-regulating air vents for uPVC windows operate without any manual control. They are mounted into the upper frame of uPVC windows horizontally. Self-regulating air vents have sensors which react to pressure or humidity changes and adjust the airflow accordingly. When there is a need for ventilation, shutters inside the uPVC window air vent are automatically activated and fresh air is let inside. As soon as the air becomes clean, most of the shutters are closed. If necessary, the air vent may be closed manually. Trickle vents are mounted into the upper frame of uPVC windows. They usually have only two positions: open and closed. Some modern uPVC window trickle vents offer an additional possibility to direct the air flow upwards or downwards, according to your needs. uPVC window trickle vents are usually fixed high above the floor and so they create no sensible draught.
Window and door air vent comparison
In order to choose the best air vent for your new uPVC windows, you need to consider your preferences and the type of uPVC window you have selected. Autonomous air vents are more suitable for uPVC windows made of wide uPVC profile, while glazed-in air vents are more suited for uPVC windows made of narrow profile. What concerns the efficiency of ventilation, vertical air vents are the best. Compared to the other two types, vertical air vents for uPVC windows let in the largest amount of air in a given period of time. However, vertical air vents obstruct the view through the uPVC window more than others. Both vertical and horizontal uPVC window air vents require manual operation. In contrast, self-regulating air vents automatically adjust the airflow. The three types of uPVC window air vents differ in terms of tightness when closed: vertical air vents may be closed completely, while glazed-in and autonomous uPVC window air vents allow a small amount of air even when they are fully closed. This is necessary because otherwise humidity might start to condensate on the uPVC window air vent, causing it to freeze in wintertime. All types of air vents discussed above protect your home from rain, burglars and insects. Glazed-in and self-regulating air vents for uPVC windows often provide improved sound insulation.
