Fiberglass insulation batts are a common option for insulating your home, especially your walls. When the walls of your home were being built, batts were most likely installed between the rafters before being covered by sheetrock. Fiberglass is usually chosen, mainly for its economic reasons. It’s cheap and easy to put in.
But is fiberglass the best option for your wall insulation? Probably not. Fiberglass, though easy to installed, is also very easy not to get perfect. It is difficult to get the batts to line up perfectly and not leave any gaps. Areas around light switches and outlets also cause gaps in the insulation. If the insulation isn’t covering the wall completely, it isn’t doing much insulating.
Even if the fiberglass batts are perfectly installed, there can be some problems. Fiberglass is highly affected by any moisture and will have a diminished R-value if it gets the tiniest bit wet. Fiberglass insulation doesn’t have the highest R-value in the first place, and moisture will render the batts almost completely ineffective.
Upgrading wall insulation
If your home does have fiberglass batts in the walls and you are looking to make your wall insulation more effective, there are still options. *Our technicians, experts* can come in and drill holes, usually from the outside of your home, into the wall. They then pump either foam or cellulose insulation into the hole. The insulation fills around the fiberglass and will fill in any gaps. after the wall is fully insulated, the *technicians* will seal the hole as inconspicuously as possible. The additional insulation in your walls, whether foam or cellulose, will help keep your house more comfortable and your energy bill down.
