Why ventilation is essential in creating an airtight home

 In Home Insulation

A SUPPLY of fresh air and the installation of a good ventilation system is essential if homeowners are to create an airtight property.

This might sound surprising but the concept of ‘airtightness’ is actually often not understood properly.

People mistakenly believe that an airtight house is like living in a plastic bag, will be hot and sticky or that they don’t need to worry about it, because they keep the windows open.

Now think about an old home with big sash windows and open fireplaces. These are the types of properties that literally leak air. Still, these are also the homes that are thought to be the healthiest because fresh air is allowed to move freely in and out of the home.

The downside is, of course, that people feel cold and uncomfortable in the winter.

The crucial difference between an old home and a modern, airtight home is that air circulation is carefully planned.

In an energy efficient home, high quality spray foam insulation is used to keep in warmth during the cold winter months, while a whole-house ventilation system ensures the air quality indoors remains clean, fresh and healthy.

Older homes may also suffer from a build-up of toxic chemicals called Volatile Organic Compounds (VOCs), radon gas and other health-damaging substances.

Often, if a home is uncontrollably leaking air from the windows or uninsulated lofts and walls, then you can bet that there is a build-up of invisible chemicals in other parts of the house which become trapped over time.

VOCs are present in everyday cleaning products and have been linked to long-term health issues. Similarly, radon gas is naturally occurring and in small amounts, it is harmless, but because of a lack of controlled air flow and ventilation, raised levels have been shown to create an increased risk of lung problems.

That’s why, at every insulation installation, Noreus can also test indoor air quality and supply ventilation systems to make sure there is also a steady supply of fresh air – meaning that an airtight home is not only warmer, but is a healthier, happier place to be.
