Insulation of the rooms of a house is a necessary element of the remodeling or the finishing process, especially in cold climates. Proper insulation can adequately trap heat within a room and make it warm and cozy. If your room is not sufficiently insulated, it will be damp, cold and uncomfortable to stay in.
The same applies to your basement if you have converted it into a room. In this blog, we will explore 3 steps to insulate the basement.
Understanding the problem
Before you proceed to insulate your basement, it is very important that you understand some common mistakes that homeowners make. In many homes, the owners directly put up wooden framed walls against the concrete. They also fill up the cavities of the framing with fiberglass insulation which is in direct contact with the concrete foundation walls. Unfortunately, this kind of setup is sure to lead to the growth of mold which in turn will pose health hazards to the inhabitants.
What many home-dwellers are unable to fathom is the significant level of moisture that concrete can retain. Most suffer from the misconception that concrete is dry by nature. We can easily bust this myth by viewing concrete under a microscope which would reveal pores and small voids. In fact, concrete possesses sponge-like properties that make it absorb water.
When insulating basement walls, we must be fully aware that concrete is moisture-laden and remodel accordingly.
Choosing the R-value
R-value is the means to measure the effectiveness of insulation in reducing cold or hot airflow. The higher the R-value per inch of thickness, the better the insulation. The R-value depends upon 2 factors. First, the climate and second, the degree to which you prefer your home to be insulated.
Homes that are situated in warm climates typically require a minimum R-value of 30. Houses in cold climates require a minimum R-value of 60.
Insulating the basement wall
To begin insulating the basement walls, use 3-4 inch polystyrene foam which will fit against the foundation walls and the rim joists. This kind of foam comes in different colors such as blue, yellow or pink. When insulating basement walls, one should always choose polystyrene foam over expanded foam. This is because the latter has a lower R-value and isn’t as durable as the former.
Draw with chalk-lines where you will make the cuts. Then, make the cuts as deep as possible using a utility knife. Snap the sheet in the same way that you would cut drywall. Wherever there are obstructions, cut around them and fill the spaces tightly with foam. Apply a line of adhesive on the masonry walls to hold the sheets back in place.
When insulating the basement, one has to take special care to ensure the finishing is done properly. Otherwise, a damp and cold room will both be uncomfortable to inhabitants and unappealing to the guests.
