DIY Foam Insulation for Basements
Basement Insulation is one of the toughest things to accomplish correctly for a reasonable price. The best approach for insulating basements is having a professional install spray foam. However, it can be quite expensive and it’s a project best left to professionals which flies in the face of many of us DIY folks. So you may want to consider DIY foam insulation as a cost effective basement insulation solution.
Foam Board Insulation is DIY Friendly
Foam board insulation is a DIY friendly product that any home owner can easily work with with limited tools and experience. Best of all the product is relatively safe to work with and won’t cause side effects like fiberglass insulation or spray foam. XPS foam insulation can be cut with a utility knife, handsaw or table saw easily to fit any configuration.
The key to a successful installation is sealing all the joints and gaps. Typically we like to seal the joints with Tyvek tape. The larger gaps are typically sealed using spray foam from a can like Great Stuff. Sealing the joints helps stop air infiltration and provides for the most effective vapor barrier possible.
Benefits of Foam Insulation
Foam insulation is perfect for basements because it won’t promote mold growth, won’t decay, won’t absorb water (closed cell) and it has great insulation R values. Foam board insulation can also provide a very good vapor barrier to prevent the movement of moisture from damp basement walls.
DIY Means Saving Money
The biggest reason we like foam board insulation is the cost savings. DIY foam insulation can save significant money compared to professionally installed spray foam while maintaining some of the great benefits that foam offers. Installing the product yourself can save as much as 60% or more compared to spray installed.
DIY projects can be fun and cost effective. Working with foam board insulation is really easy and it’s a project that inexperience DIY’ers can tackle. Be sure to check with your local code officials on energy code requirements to be sure you’re installing a sufficient amount of insulation. Have fun and enjoy your warmer basement!
