Choosing The Right Basement Insulation

The Best Products And Quality in Building Supplies

Basements are often neglected spaces in the home because they are damp, cold and sometimes a health hazard due to poor insulation. To deal with the insulation problems in your basement once and for all, you need to take time and find the best product. Insulation board suppliers usually recommend rigid foam insulation for basements. Let’s learn more about this product and find out if it’s an ideal option for your home.

Blanket Insulation (Fiberglass)

Fiberglass is a commonly used insulation material in most homes because of its low cost. Rigid foam insulation is a better alternative, although it happens to cost a lot more than fiberglass. If you don’t have any major moisture concerns in your basement or your budget is extremely limited, fiberglass is an ideal option.

Why XPS (Rigid Foam Board Insulation)?

XPS insulation, also known as extruded polystyrene is available in different thicknesses. This insulation material provides you with a thermal capability of R-value 5 per inch of thickness. This is certainly more expensive than fiberglass insulation but offers a wide range of benefits. There are other forms of insulation to consider such as loose-fill. The major drawback with many of the other options is that they are not DIY friendly. XPS is easy to install without much technical knowledge. It doesn’t require any special equipment therefore it’s not costly to install.

Benefits Of Rigid Foam Insulation

Basements are usually highly susceptible to water. The insulation material installed on your basement must do a good job at preventing moisture penetration. The best part about the rigid foam insulation is that it is water resistant. Unlike other insulation materials like fiberglass that holds water overtime and creates mold, XPS helps to resolve moisture issues in the basement. Even though the drywall in your basement can still hold water, you should be able to see it and take action before it spreads.

The Installation Process

XPS can be applied on painted walls. Just make sure you perform the required treatments such as applying basement waterproofing paint before insulating the walls. Before the installation is done, you need to ensure that you have a clean and dry surface. Get rid of cobwebs on the walls and gather all the tools required for the job. You’ll need a foam board adhesive, a drywall saw and caulk gun to install the rigid foam insulation.

Application Tips For Rigid Foam

  • Use the adhesive liberally making sure you’ve covered the corners and along the edges.
  • As you wait for the adhesive to cure, use something to hold the boards firmly in place against the wall.
  • To ensure that all areas are covered, install full pieces and after the adhesive is cured you can use a drywall saw to cut the openings.
  • Make sure the seams are tight enough to prevent air from entering or escaping through the insulation.
  • Use tapes across the joints when you finish applying the insulation. If there are larger gaps remaining, you can use expandable foam to fill them up.
