Blown Insulation Vs. Fiberglass Batts

Posted on

When you insulate your home, you need to consider the different types of materials on the market and choose a product that will keep your costs low not just initially, but for years to come. Fiberglass batts are common for insulating a home, but you might also have the choice of blown insulation. Carefully weigh the advantages of each before you make a choice. 

Blown Insulation

Blown insulation can be made from recycled newspapers, rock wool, or strands of fiberglass. Bags of the material are fed into a blower which breaks up clumps and sprays the material into the space to be covered. One advantage of blown in insulation is that it is easier to fill awkward-shaped spaces in your attic or walls, since the material is blown in and then settles down into the space to be filled. Blown insulation will cost between $1.60 and $2.50 per square foot to install. One problem with blown insulation is that it can settle over time and lose its ability to insulate your home. Cellulose-based insulation is the most prone to settling, so if you go with cellulose insulation, you will need to increase the amount of insulation you use by 20% to counteract the effects of settling. Increased material can drive up your costs, and it may not even be an option depending on how much space you have to work with, so you should consider this before you decide to use it in your home. 

Fiberglass Batts

An insulation batt is a slab of material made from fiberglass wool mixed with a resin to aid it in holding it together. These batts come precut in lengths and widths to match the height of the walls and the space between studs in the average home. Because fiberglass batts come precut, you have to do some cutting to fit them into tight spaces in your home, and because of the necessity to measure and cut carefully, you may end up with uninsulated gaps. On the other hand, fiberglass batts cost between $.60 and a $1.20 to install; thus, they are the cheaper option to install.

Final Analysis

If you have a lot of gables, bay windows, dormers, and other intricate structures in your home, blown insulation should offer the best coverage and help to keep heating and cooling costs down in the future. On the other hand, if you live in a home that does not have a lot of intricate architecture, then using batt insulation is probably the most inexpensive choice.
