Everyone is talking about air tightness but only a few people know the meaning and the facts about complete building sealing:
The sense of a complete building sealing solution is, to protect your home against draught, dampness and heat-loss.
Modern houses nowadays mostly want to gain from the benefits of under floor heating, heat pumps and heat recovery ventilation. It is a fact, that these systems do not work in an efficient way, whenever the house does not provide a good value for air tightness.
The air change rate at 50Pa differential pressure (ACH@50Pa) should not exceed a value of 1.5. This means nothing else than the complete air in the building gets changed 1.5 times per hour through leakages in the building envelope, whenever a wind with a speed of roughly 36km/h is constantly blowing .
To save energy and ensure a controlled ventilation, it is absolutely essential to plan and create and monitor a full working air tight layer for your house.
