"Owners did the estimate, were on site for the insulation install...what more can be said about customer service! They were 5+. Now I must tell you about the job...it was difficult adding insulation to the underside of floor boards in our crawl space. Other insulators said it couldn't be done. Kelly took her flashlight, measuring tape and looked really hard and said "We can do this!" What a "can do attitude" and they accomplished it. I will definitely use them again and so should 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.

The most affordable way to insulate behind unfinished walls is to install fiberglass batts or rolls. These total around $0.75 per linear foot, with the width matching the gaps between standard studs perfectly. However, it’s important to consider the R-value of your insulation and the climate in your area, as fiberglass insulation isn’t the best in terms of preventing heat transfer. Plus, the most affordable option may cost more on electricity bills over time. The most affordable way to insulate behind finished walls is to leave them up and use blown-in insulation to avoid drywall replacement.

Excluding carpet, strand-woven bamboo provides excellent underfoot heat. Laminate flooring is also good for insulation and preventing cold feet in the winter. Bamboo tends to work better in climates that have more consistent temperatures, while laminate does a better job at insulating floors in homes that experience more extreme temperature changes, such as the deciduous climates of the northeastern U.S.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

To keep cold out, look for treatments that sit close to the window frame and are made from thick, insulating materials. Thermal curtains, cellular shades, window quilts, and insulated shutters can all help retain heat. Layering window treatments, like pairing lined curtains with cellular shades, can provide even better insulation by further reducing drafts and heat transfer.
