Attic spaces built before the year 1990 were not furnished with vents, meaning that the upstairs areas used to be very hot during the summer and extremely hot during winter time. Yet, they did not seem to have any trouble with mold and moisture. The reason why modern buildings are infested with mold is that they have too much insulation. To be more precise, people in general insulate house components such as doors, windows and ceilings, the result being not that which they had expected. Since modern isolation captures both the heat and the humidity, it provides the perfect environment for mold colonies. The mold in the loft festers and eventually causes damage to the building materials. However, there is a solution to this problem: spray foam. If you are worried the price is too high, then you can get spray foam insulation quotes.
Why does mold appear in your home?
You may very well ask yourself the following question: “Why is my home affected by mold?”. There is only one answer to this question: mold is the natural result of moisture. Even if you do not own a house built in the 1900s, there may still be some structural issues. For instance, there may be cracks in the wall that allow the air to come in. What happens when the warm air gets in contact with the cold air condenses and it will remain there. The big problem is that moisture travels through the air. Taking into consideration that almost 99% of the moisture is carried by the air, you should make sure to limit the amount of indoor mold that is growing into your home by preventing air leaks.
How does spray foam insulation work?
The fact is that in order to reproduce mold require tiny spores, reason why the fungus frequently grows on wood, paper and carpet walls. Therefore, the only practical solution to prevent mold growth is to seal your home efficiently. Not only will insulation stop mold development, but it will also be good for protecting you against rodents and dust. The best insulation solution for your problem is spray foam because it is strong, not to mention that it crawls into tiny spaces. If you have rooms where condensation is likely to form, then you should use this isolator because it will maintain the integrity of your home and mold cannot possibly thrive inside.
Can you use spray foam on fiberglass
Keeping moisture out of your home is important, but pay attention to the fact that foam insulation does not work well on fiberglass. Although this solution typically forms an airtight seal and thus keeps the moisture from forming, it does not have the same effect on fiberglass. Not only does it not stick to the fiberglass, but you will deal again with outside air. What you should be doing is removing the fiberglass and using only spray foam because it has a better R-value. This means that it will keep your home as warm as possible.
