Fiberglass insulation has long been the go-to choice for homes, but homeowners who want the most effective, efficient insulation possible are often encouraged to consider an alternative like spray foam. While these alternatives are effective, they're also harder to come by and more expensive than fiberglass. If you're on a budget and need to insulate your home now, fiberglass is still a very suitable choice – but you'll want to follow these tips to make it as effective as possible.
Use the right amount.
Far too many homeowners head to the home improvement store, buy a roll of insulation, and put it into place with little thought of how thick the roll is compared to how thick it needs to be. Under-insulating your home will lead to higher energy bills, and over-insulating it is just a waste of cash. Before you shop for fiberglass insulation, use an online calculator to determine just how much you need based on the climate in your area.
The calculator will give you an R value, which refers to the insulation's ability to trap heat. Match the R value that the calculator specifies to the R value of the insulation that you buy. You may need to use two layers in areas where you need a high R value. For example, if the calculator says you need R44, you can buy two R22 rolls and plan on using two layers of insulation.
Don't leave gaps when unrolling the insulation.
If you leave a gap of an inch or two between strips when unrolling the insulation, heat can escape through this gap. So, be very careful when unrolling the insulation that you place the strips directly next to one another. Use your (gloved) hands to pull one strip horizontally towards the other. If you have to use two layers, unroll the second layer perpendicular to the one below it. This will help seal any gaps, too.
Be careful when choosing backing.
For the first layer of insulation, you want the type with metallic baking. This helps reflect some of the heat and also prevents the accumulation of moisture within your insulation. For the second layer (if you have one) you want the type without backing. If you choose the type with backing for the second layer, heat will get trapped within one layer of insulation instead of being dispersed throughout the insulation.
As long as you follow the tips above, you can insulate your home quite effectively with traditional fiberglass insulation.
