How Not To Overspend When You Buy Wall Foam
Tuesday, May 25th, 2010Spray wall insulation also known by the phrase spray foam insulation is done primarily through the use of two different spray foams. That is closed-cell foam (isocyannurate) and open-cell foam (polyurethane). A closed-cell foam often possesses more R-Value (term used in describing a substance’s thermal resistance) than the open-cell foam. It is waterproof unlike open-cell so the wall foam created from it prevents mold formation that can make you sick or ill.
So how will the insulation work in protecting your home from temperature loss or gain? First, the foam used is applied with the help of a spray gun to fill cracks or spaces in the walls of your home. Once these are filled, air flow out is reduced and loss of cold air or heat is minimized to as much as 10% and even lesser. That is spray wall insulation or even the other insulation types seek to retain temperature in your property.
The foam used in this process is a liquid made from two substances, namely: polymer like isocyanurate and a foaming agent, which makes it swell to nearly a 100 times its previous volume when this is added. As it expands it fills every space or gap that it encounters creating wall foam that compensates for these exit points.
The benefits of this type of insulation are quite much in addition to the health benefit mentioned earlier. First, it makes your home more comfortable since room temperature is regularly maintained; secondly, it adds a permanent structure to your home that will not sag.
One other benefit is that it gives strength to the structure of your home building. Another benefit is it reduces energy cost as you will be paying less as you consume less energy.
Speaking about cost, this type of insulation is not as cheap as other types of insulation. Installed charge for sprayed wall foam installation begins from say $1.25 to about $2.25 per square foot. Cost depends on thickness of wall and foam type.
Although spray wall with foam insulation is considered to be quite easy, this type of insulation requires knowledge and skill for anyone to carry this out, so if you are a DIY (Do It Yourself) enthusiast without the necessary skill and knowledge you should do this by yourself.
Most sprayed wall foam from this type of insulation are environmentally friendly and do not have HCFCs that are dangerous to the earth’s ozone layer. This, however, does not mean you should not carry out a check on substances which constitute elements that make up the insulation materials that will be used in your home.
