One of the disadvantages of SIP panel houses is poor ventilation. It is evidenced by condensation on the windows, mold and dampness in the corners.
The task of ventilation in a SIP house
This is high-quality air exchange, without draft. A few years ago, home ventilation from SIP panels was equipped with natural draft, air conditioning, today this technology is considered obsolete and not effective.
Natural traction does not justify itself if the house is below 3 floors. According to physical laws, significant traction is required for good traction. But SIP houses are not built above two floors. The draft intensity in a natural ventilation system is influenced by the outdoor temperature, the lower it is, the better the system works. And another significant drawback - in winter, a lot of heat is blown out of the house with a current of air.
The exhaust forced ventilation of the house from SIP panels is devoid of the first two drawbacks, but it also intensively blows heat out of the house. In addition, exhaust fans are noisy and take a lot of electricity.
The value of ventilation in houses from SIP panels
Despite the fact that SIP panels are absolutely harmless to human health, ventilation in the SIP house is needed. The developer mounts the house along with the ventilation system. The guarantee for the construction is 5-10 years, it extends to all engineering units.
Often, houses are only equipped with exhaust fans in the kitchen, in the toilet and bathroom, which expel the air through the pipes to the outside.
But, according to some experts, such ventilation is not enough. Therefore, forced ventilation blow-in is proposed. The scheme of its operation is simple and effective: pulling exhaust air from the room, the system filters it, adds fresh air from the street and drives it back into the house. The house is constantly maintained at the same temperature. The price of the system along with installation is about 2 thousand US dollars. From time to time it is necessary to change filters. However, if you calculate how much the repair of the building frame will cost, the installation price does not seem so high.
Installation of ventilation in SIP houses
Installing high-quality ventilation in SIP houses will significantly extend the life of the building. Often condensate collects on the front doors, arranged on a metal frame. Condensation can be prevented by installing an additional wooden door or by attaching a small vestibule with an area of about two square meters to the house outside.
