How to Insulate Your Basement Walls

Making use of insulation solutions in your home helps you save a lot of money and it reduces unnecessary heat loss. Keep in mind a basement insulation project such as this may require a permit. For this reason, make sure you call the local permit office and ask whether you need one.

An insulated basement enhances the comfort of your home. It will also take you less time than before to cool or heat your basement if it is insulated. Apart from helping you save money and energy, insulation absorbs the sound waves.

Step 1 - Treat Moisture

Before actually installing the insulation onto the wall of your basement, use a damp towel to clean it, then let it dry thoroughly. Now install the polystyrene insulation into the wall. This primary cleaning prevents mold from growing on the basement wall.

Affix the polystyrene insulation with an adhesive, applying it beneath the insulation itself. Use an appropriate tape on the polystyrene seams to protect both the insulation and the basement wall from moisture.

Step 2 - Frame the Wall

Now it is time to start framing the wall. Utilize composite decking for the beam at the bottom. Ensure the decking is treated with a water repellent to protect against floods or water leaks from pipes.

Put the composite decking along your basement floor and use a nail gun to fasten it into place. Put a pressure-treated bottom plate on the side of the composite decking. It will stand on the bottom beam when you raise the wall frame.

Step 3 - Attach the Beams

Affix the 2x4-inch beams to the bottom plate with nails. Drive the nails into the bottom plate at a minimum depth of .5-inches. Ensure you have a beam on all ends of the bottom plate. The local construction codes determine the distance of the beams from one another, but this distance is approximately 12-inches in most cases. Use nails to fix a top plate on the row of beams at the open edge. Make sure you drive the nail at a minimum depth of .5-inches there as well.

Step 4 - Install the Wall Frame

Elevate the top plate and raise your wall frame onto the composite decking. Check the frame is straight with a builder’s level. Use nails and a hammer to fasten the frame securely into place.

You can add extra insulation between the beams. Make sure you are wearing appropriate clothing and safety equipment such as gloves, goggles, long sleeves, and a respirator. Install drywall and fasten it firmly to the beams with drywall screws.
