Do basements need sump pumps? why doesn't my basement have a sump pump.
Impervious insulation is always an excellent idea for basement walls, but it’s absolutely essential where the floor joists of the level above meets outside walls along the edges of a basement ceiling.
Basement Insulation. A properly insulated basement can save you money on heating and provide a dry, comfortable living space. In most cases, a basement with insulation installed on its exterior walls should be considered a conditioned space.
Insulation Materials Are The Key. The key to successfully insulating basement walls is selecting insulating materials that stop moisture movement and prevent mold growth. Basements are the perfect location for foam type insulation products.
Insulating basement walls properly is extremely important if you want to enjoy your finished basement investment. Every year thousands of basements are finished with poor insulation details that lead to mold, mildew and moisture problems that render the newly finished space un-usable.
Insulating the basement ceiling will keep most of the heat upstairs in the living space. As a result, the basement will be colder in the winter making it important to also insulate any water pipes or heating/cooling ducts in the basement.
It provides the best coverage and R-value and and functions as a moisture barrier in and of itself. … But if you use fiberglass insulation batts, then a moisture barrier will prevent water and moisture from entering your walls and creating mold and mildew.
Soundproofing the basement ceiling is the best way to reduce noise transfer from the basement to the rooms above and noise from above into the basement. Sound can be airborne or impact noise. An unfinished ceiling with exposed joists does little to reduce sound transfer.

Walls. Basement walls should be insulated with non-water sensitive insulation that prevents interior air from contacting cold basement surfaces—the concrete structural elements and the rim joist framing. … The best insulations to use are foam based and should allow the foundation wall assembly to dry inwards.
When to Use Spray Foam Use spray foam insulation on basement walls when the walls studs have already been installed. Spray foam is best when you need continuous insulation with no gaps to permit air infiltration. It is an excellent solution for irregular walls and for walls with many cracks, seams, and joints.
There are several types of basement wall insulation, including sprayed foam, bubble foil, foam board and fiberglass. Sprayed foam insulation is a viable choice for a homeowner who is looking for a do-it-yourself option for a finished basement. The foam is applied in exactly the manner as it sounds — with spray cans.

In short, you should indeed heat your basement in cool and cold climate areas. … When this cold air rises, it is drawn across the floor of the main level, causing cold feet and other comfort problems. To battle this, you could wear really warm socks–but you could also heat your basement.
Insulate a Basement Ceiling: national average cost The national average materials cost to insulate a basement ceiling is $0.95 per square foot, with a range between $0.57 to $1.33. The total price for labor and materials per square foot is $1.92, coming in between $1.18 to $2.65.
The Basics of Basement Walls Attach wood furring strips, Z-shape channels, or 2×4 studs to flat, dry masonry walls, then add insulation and cover the strips or studs with drywall. Such treatments give basement walls a smooth, even surface that accepts finish materials such as paint, wallpaper, or paneling.
Should I use visqueen or plastic sheeting on the framed basement walls? No you should not, as plastic will prevent moisture from moving through the wall and will lead to mold and damage.
Remember, fiberglass does NOT resist moisture, so it’s generally a no-no when insulating basements. You can reduce the risk of moisture issues if you first cover the concrete with a continuous layer of rigid foam or closed-cell spray foam. … Closed-cell spray foam is the best way to insulate concrete basement walls.
You’ll need 1.5 inches for roughly R-10. Rigid foam board is the ideal basement insulation for the interior. It can be glued directly to the concrete to provide a vapor barrier and significant insulation value. Most contactors recommend using at least 1.5 inches in all climates.
The most common way to cover concrete walls in a basement is drywall, a.k.a. sheetrock. Drywall comes in panels panels made from calcium sulfate dihydrate or “gypsum.” Panels come in different thicknesses and sizes, the most common being 4′ x 8′ x 1/2″ thick.
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.

Placing a Basement Vapor Barrier Over Exposed Bottoms of Overhead Floor Joists Forming the Basement Ceiling. One option for a floor air/vapor barrier is a polyethylene [plastic] sheet placed over the floor joists and sealed to the wall vapor barrier.
You should heat your unfinished basement. If you have cold floors, then insulating the basement ceiling will help the most. Once insulated, heating an unfinished basement will help warm your whole home. … Heating a drafty uninsulated basement is the same as burning money for warmth!
In attic floors, above the insulation, you are asking for trouble. Pipes in an unheated basement are usually safe from freezing because basement temperatures rarely go below 40, even in the coldest of winters, and sometimes when the heat goes off.
Spending time in your basement during the winter months can be downright chilly. Most homes, even those with finished basements, are significantly cooler than other areas. This can make using your basement during the colder months overly expensive to keep warm.
Concrete block makes a cost-effective and structurally sound wall, but it has little thermal resistance. Depending on the density of the blocks, an 8-inch thick block wall without any other type of insulation has a thermal resistance value between R-1.9 and R-2.5.
Any heat inside the home will pass right through the concrete with very little resistance. The concrete acts as a sort of bridge for your heat to get outside. We eliminate the bridge and keep heat in by adding insulation. In order to regulate the temperature of a living space, concrete needs to be insulated.
Use furring strips attached to basement walls: basement panels can be used in a basement finish not using studs and drywall. As such, all you need for support are some furring strips attached to basement concrete side walls.
The thickness of foam insulation in basement walls will range between two to seven inches, depending on where you live and whether you use open or closed-cell spray foam insulation.
