Will Keep you Warm and Dry

Many homes are built with unfinished basements. Unless you have specified to your new homebuilder that you would like it finished, and pay the added costs to do so, yours will be unfinished as well. Finishing your basement is a do-it-yourself project that a lot of homeowners take on themselves. The first thing you should take care of when starting your basement renovation is insulating the walls. There are many types of insulation from which to choose.
  •  Fibreglass insulation is sold in rolls or batts. It is one of the older forms of insulation. This cloth is generally more affordable, and easier to install as a do-it-yourself project. Fibreglass is made up of billions of strands of glass woven together. This allows for a greater surface coverage area at lighter weight. It is non-combustible and non-absorbent. The drawback of this insulation is that you should be very well protected when working with or around it. The tiny pieces of glass that make up the fabric can become airborne when is it moved around making it possible for them to be inhaled. These strands are also so fine that they get in to your skin and can cause irritation, itching and rash.
  •  Blown-in insulation is made of either fibreglass or cellulose. It comes packaged in large blocks that are broken down in the insulation blower. A large tube that is attached to the blower is directed to where you want the insulation to go. The benefit of this insulation is that it can be used over existing insulation in your attic to increase the R-value. Its small particles allow for it to settle in to gaps and crevices giving it the ability to cover a large area. One con associated with blown-in insulation would be the clean up as the small pieces can fly around and settle in other areas.
  • Foam board comes in sheets much like drywall. It is available in several thicknesses and R-value ratings as well. Common uses for foam board insulation are basement walls and on top of concrete basement floors between other types of flooring. Foam boards can be fitted between wall joists in your basement and will offer an excellent airtight barrier. This material can be used on the exterior of your home as well. It is a superior weather barrier due to its impermeable nature. Foam board insulation is made up of tiny air bubbles contained within a medium such as polystyrene.
  • Spray foam is probably the most effective and certainly one of the most popular. Spray foam is an expanding foam insulation that is sprayed onto the surfaces of your home that you intended to have insulated. High-powered machines that utilize compressed air propel the liquid foam through a nozzle to completely cover the area specified. It instantly expands and dries into a hard air and watertight seal. Its application can be used on the interior or exterior of your building making it a very versatile choice. The installation of this product is generally completed rather quickly, and certainly much quicker than other insulation options.
All that you have to do now is decide whether the insulation of your basement is something that you can take care of on your own or if it is a job better left to the professionals?
