Wall insulation is a great way to reduce heat loss and save money on your energy bills. It also helps to reduce condensation and moisture, which can lead to mould and bacteria growth. While you may not think about it, the use of insulation can help reduce noise. It can also be useful for sealing tiny cracks in your house.

The best way to insulate your exterior wall is to install rigid polystyrene foam. This foam is designed to adhere directly to concrete walls. It looks like cotton candy and is very effective at keeping air and moisture out. It can be used on its own or with drywall, and can be applied on the inside or outside of a wall.

For a DIY project, try installing Nu-Wool, which is a premium cellulose product that lasts a long time. There are other types of cellulose insulation, such as open cell spray foam. These products can be expensive, so it is best to hire a professional.

For a larger project, you might want to consider installing Insulating Concrete Forms (ICFs). These two-panel foam panels act as an insulating medium and building form. Compared to other options, they are a bit more expensive, but they are very durable.

To install this, you will need to make a small hole in your wall. This can be done with a screwdriver or other sharp object. Once you have made the hole, seal it up with a Styrofoam plug. The hole should be the same size as a dime.

The next step is to seal the vapour barrier. You can do this by putting a sheet of polyethylene in the hole or using a high-density spray foam. This is important because it is the vapour barrier that keeps the moisture from escaping from the wall. In addition to the air barrier, you should also consider insulating the area around the plumbing pipes. This is because air pressure increases as the wall fills up with insulation.

The other important thing to do is to seal the edges. This will prevent leaks and gaps from happening. In addition, it can be important to insulate your electrical wiring. This will ensure that your home stays warm and comfortable.

If your home is at risk for flooding, it may be a good idea to insulate your exterior walls. This will reduce the effects of driving rain on your walls. In addition, if you live in a flood prone area, it is a good idea to insulate your pipes as well. This will keep your home healthy and prevent mould and bacteria from growing.

There are many types of insulation products, from man-made to natural. Which one you choose depends on the design of your home and its climate. You can find the best products for your needs by contacting a specialist in your local area. For example, Owens Corning R-21 Kraft Faced offers the R-value of R-21 per square foot, and it comes in pre-cut lengths.
