"The guys did a great job for an affordable price . During covid with a supply issue still managed to get the job done right ! My attic was at 160 degrees during the summer I have dropped it down to 85 to 90 . Do not worry about your old insulation being removed your attic will become a conditioned space left over insulation will result in moisture that you don't want in your attic .Great job guys best of luck to you ."

Insulation questions, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

While carpet over carpet may provide some additional insulation and soundproofing benefits, it's not as effective as other methods. Layering carpets can add a modest buffer against noise and temperature fluctuations, but it's limited compared to installing thicker carpet padding or using specialized soundproofing materials. For optimal floor insulation and soundproofing, consider alternative solutions tailored to your specific needs and budget, such as adding additional padding or soundproofing underlayments beneath the carpet.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

The life span of fiberglass insulation can be as long as 80 to 100 years, but because of changing building codes, it’s best to get your insulation checked every 10 to 15 years. Signs of degrading fiberglass insulation include bits of batts on the floor or batts detached from frames. Having optimal, healthy insulation in your home will improve its energy efficiency, lowering your monthly bills.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
