When it comes to insulating a home, homeowners are most familiar with batt insulation, which comes in large rolled sheets. Yet more and more people are turning to what is known as blow-in insulation, which boasts effective results and a much easier installation process. If you would like to increase your knowledge of home insulation techniques, read on. This article will provide a handy introduction to the world of blow-in insulation.
Blow-in insulation consists of relatively small loose particles. As its name makes clear, these are installed by blowing them into place using a special blowing machine. This saves the tedious effort of measuring and cutting larger pieces of insulation down to size. Instead, the insulation can effectively be blown into place within minutes.
Blow-in insulation may be composed of one of two different materials: fiberglass and cellulose. Both of these materials will deliver relatively similar insulation power, leading many to simply go with whichever happens to be less expensive. Yet it is important to note that cellulose presents a couple of additional benefits.
The most important of these benefits is that cellulose insulation is much more fire resistant than fiberglass. In fact, it has been determined that the fire resistance of cellulose may be up to 57% greater than that of fiberglass. Additionally, cellulose is generally considered the more environmentally friendly option, thanks to the fact that it is largely composed of recycled materials and has a less energy intensive production method.
How Much To Buy
The biggest question many people have about blow-in insulation pertains to how much they will need to buy to fulfill their insulation needs. There is no hard and fast answer to this question. The answer is related in a large degree to the particular climate in which you live. In other words, the colder the region, the more insulation will be required. The best way to gauge how much insulation you will need is to calculate the square footage of the area to be covered, then consult an insulation table to determine how deep the insulation will need to be to give you the R-value appropriate for your region.
The Blow-In Process
As noted above, blow-in insulation is installed using a special blowing machine. This machine generally consists of a motor, an insulation hopper, and a long flexible hose. Generally, the installation process is accomplished by two people, with one filling the hopper with insulation while the other wields the end of the hose, directing where the insulation will fall.
