Homes with crawl spaces foundations can have problems with moisture and energy loss due to the area beneath being open to the outdoor climate and environmental conditions. Therefore, options like encapsulation are great investments to reduce energy loss and prevent damage to homes. If you are planning on doing the crawl space encapsulation for your home, the following tips will help you prevent problems and improve energy savings:
1. Use Spray Foam to Stop Air Leaks from The Holes in Your Floor
Spray foam can be a useful insulation for different areas of your home, such as attics, sealing the penetrations in exterior walls or for your crawl space. In the crawl space, there may be ducts, pipes and other mechanical installations that go through the floor and open your home to air leaks. Seal these areas with a can of spray insulation to stop air leaks and energy loss that comes from your crawl space.
2. Insulating and Sealing Floor Joists from The Crawl Space Area
The exposed floor joists in a crawl space foundation can be a major cause of heat gain and cold winter drafts. Therefore, you want to make sure that the floor joists in your crawl space are well insulated and inspect the insulation regularly. In addition, you may want to seal the insulation with a membrane or textile material to protect it from damage and improve the energy efficiency of your home.
3. Insulating Block and Concrete Foundation Walls to Stop Energy Loss
The foundation walls of crawl spaces are usually not insulated, which allows for air to freely flow beneath your home. This can be the cause of drafts in the winter and heat gain in the summer. To improve the energy efficiency of your home, you will want to insulate block or concrete foundation walls that expose your home to the weather outside and energy loss.
4. Leveling the Foundation Floors and Sealing Them from Moisture and Weather
Usually, the floors beneath a crawl space foundation are just the natural dirt. It may be uneven and full of things like rocks and gravel. First, level the floors and remove any rocks or debris that is in the way. Once you have the floor of the foundation of a crawl space, you will be ready to seal it with a plastic or rubber membrane liner to keep moisture and the weather outdoors out of your crawl space.
These are some tips that will help reduce energy loss and problems when doing a DIY crawl space encapsulation.
