One of the most common questions homeowners ask when they invest in crawlspace waterproofing is whether they should insulate areas with dirt or not. There seem to be differing views all over the internet regarding the need to insulate a dirt crawlspace and you may be wondering which way to go. Read on to find out more.
Why is insulation important?
You may have come across some online articles that advise you not to insulate this important space. However, this is simply comical. Why would you not want to insulate this area? In fact, the international building code requires residential homes to have insulated crawlspaces.
If you are going to pay someone money for waterproofing services, they should include insulation of the crawl space as part of their services. This will ensure that your home meets building code. It is the same as paying an electrician to do your wiring. Would not you expect them to do it up to code?
It is also important to remember that building code only provides minimum standards that you are required to meet. This means that insulating your home and other vital spaces is one of the minimum standards that your home should meet.
If you are thinking of insulating areas of your home as part of the waterproofing process, you should think about the long term benefits of your investment. It is important to plan the insulating based on whether your crawlspace is encapsulated or vented.
Vented crawlspaces are common in homes located in areas of low humidity. If this is the case in your home, you can install rock-wool or fiberglass for insulation. The rock-wool ought to have been mixed with spray foam. This will increase the air sealing properties of the rock-wool.
The insulation should not only provide a thermal barrier but also prevent air from the crawlspace from entering the living space above.
Encapsulation techniques recommended for areas with high humidity. Encapsulation seals off this space from the surrounding environment.
The problem with insulating the subfloor in these spaces is that mold or mildew can grow in the insulation. You should, however, insulate the walls of the crawlspace. This will result in a more energy-efficient home.
Consider sealing the subflooring to prevent air from the crawlspace from entering the living space above. Air sealing will help to make your home even more energy-efficient.
