To get some fresh outdoor air into your home is important for your health


Fresh outdoor air contains 400 ppmv (parts per million volume) of CO2 (carbon dioxide). Humans and animals exhale the same gas at the same time in amount that depends on their physical activity. In rooms that are not sufficiently ventilated, this gas accumulates and causes what we can call the stuffy air. Staying in such rooms can lead to many health problems - from fatigue and drowsiness to irreversible damage of your health. 

 Content of the CO2 for feeling of the fresh air is up to 700 ppmv. Values above 1000 ppmv are less suitable for permanent residence and sleeping (eg in the apartment), above 1500 ppmv is unsuitable. At 5,000 ppmv (PEL - Permissible Exposure Limit), the stay must be limited for the shortest time as possible.  At 25,000 ppmv (NPK - maximum admissible concentration) there is a risk of death by suffocation.  The correct ventilation intensity in the room or house can be calculated according to the number of people in the room and their physical activities. For example, if there are 3 people in the room, the first one weights 110 lbs and sleeping. The second one weights 176 lbs and hoovering, the last one is132 lbs heavy and riding on the stationary bike, This situation causes that the value of CO2 increases on  2978 ppmv per hour, more than three times exceed the value for feeling fresh air. 

This is why we recommend  tilt & turn windows because  uPVC tilt and turn windows give you complete ventilation control, ideal for homeowners who are looking to control the airflow without compromising security. They are great in the summer allowing plenty of free-flowing air to enter your home keeping your home cool in the hotter months, Can tilt a full 90 degrees for maximum ventilation, or inwards for fresh air.

UPVC WINDOWS ALWAYS ADAPT TO YOUR NEEDS – PART 2

The number of chambers is not only important value to follow The outer wall of the uPVC profiles is usually 2.8-3 mm thick, with the inner cavity of the profile divided by partitions into several chambers. Usually, more chambers mean better thermal insulation properties. What is more significant than the number of chambers is the coefficient of heat transfer  through the frame - the  lower the coefficient, the lower the heat losses across the profile. On the other hand, fewer chambers mean more space for steel reinforcement, which can then be more massive. The greater the window size, the higher the requirement is for the static load-bearing capacity that the metal reinforcement provides. These design elements determine the maximum size of the windows that can be produced from the profile type. The uPVC windows are excellently proven both in the construction of new family houses and in the reconstruction of older houses because of their variable capabilities.  The connection
