Is it a good idea to spray foam basement walls?
The best way to insulate the interior side of a basement wall is with foam insulation that is adhered to or sprayed directly on the concrete. Any of the following insulation materials are acceptable for this purpose: closed-cell spray polyurethane foam or either XPS, EPS, or polyisocyanurate rigid foam.
Is spray foam insulation good for basement walls?
Closed cell spray foam is a great fit for your basement walls if you plan to leave the walls exposed. This is because closed cell can take a lickin' and keep on tickin'. Closed cell spray foam is a durable insulation material, so it doesn't have to be covered as open cell does.

Why does my basement smell?
The warm air comes in contact with the cold walls and condenses into water, similarly to a cold drink on a hot day . The walls don’t get warm enough or sufficient air movement to completely dry. This water formation provides the perfect breeding ground for mould. The smell that is typically associated with a basement is actually caused by that mould.
Why are fiberglass batts drying out so slow?
Once moisture has formed in the wall, the drying out process is extremely slow because of the vapour barrier. Once fiberglass batts have gotten wet they are permanently ruined. So what we need is an air impermeable system to isolate the warm interior air from the cold exterior walls. This means you need a foam product.
Do you need to fram before spray foaming?
Typically, the framing is done prior to the spray foam being installed. This will allow you to maximize the floor space of the finished product. With that being said, some rim joist cavities can be difficult to access after the walls are built. Some special attention has to be given to those areas. In some cases, it’s better to spray first to ensure we get that good quality seal from bottom to top.
Is spray foam insulation good for basements?
Air Sealing. We know why the other systems fail, so let’s take a look at why spray foam insulation really is the best option for any basement. First and foremost is the obvious: Air Sealing! We know that moisture problems are caused by a lack of air sealing, spray foam insulation is as the name implies, sprayed in place.
Can you use 2x3 lumber for basement framing?
Many times the framing can be done with 2 ×3 lumber because once its locked into the spray foam it will be very strong. This cuts on cost and also increases the amount of usable floor space slightly which can be handy in small basements.

Where is foam sprayed?
This is sprayed into wall cavities or other confined spaces. The rapid expansion leads to the foam evenly filling the space and providing an equal layer of insulating coverage throughout.
What is spray foam insulation?
SPRAY FOAM. INSULATION. GUIDE. Spray foam is a form of insulation that is sprayed into wall cavities or attic space. Unlike blown-in insulation, which is inserted into space in the same way, spray foam has the benefit of beginning as a liquid. As it dries, it hardens and expands, meaning you can fill a space without leaving any gaps.
Why is slow expanding foam used?
This means that it flows over obstructions before it expands or cures, thus helping it to fit around irregular shapes and more evenly fill an awkward shape. For this reason, slow-expanding foam is usually used in existing buildings that may contain wires and pipes in the wall cavities.
What is closed cell foam?
DENSITY: Closed-cell foams are more high-density as the individual cells are closed. The foam contains a gas that helps the foam expand - thus filling the space around it. Closed-cell foams tend to be denser and therefore more rigid when they set.
How many different types of foam are there?
There are five main different types of foam, each of which has slightly different properties. Which one is best for you will be based on:

Can you use open cell foam in a basement?
Most homeowners are unaware that open cell spray foam insulation won’t absorb and retain water, so if the basement leaks, it will show the homeowner where the leak is so it can be fixed before causing further damage. Because of this and open cell foam’s superior sound dampening abilities, more and more homeowners choose open cell spray foam to insulate their basement.

What is spray foam insulation?
Spray foam insulation is used inside of a home for these very purposes, in an effort to add insulation within the home to trap and contain temperature and thermal insulation, while also minimizing air infiltrations in the indoor space. Although spray foam has an important function inside of your home, it can also present adverse conditions in this indoor space upon its application in the confined environment.
Does polyurethane foam offgas?
There is no doubt that after you have applied the polyurethane spray foam insulation within your indoor environment, the off-gassing of the chemical structure of this building material will shortly follow. And when the off-gassing occurs it will lead to volatile indoor air quality, strong chemical odors, and a potentially dangerous environment for occupants to inhabit during the curing time. As we discussed previously, off-gassing is the process in which materials that are composed of chemicals turn to a gaseous compound (usually from a liquid or solid) due to the ambient conditions present in an indoor environment, allowing it to steadily release off into the air.
