Drywall Insulation questions, answered by experts

The average U.S. homeowner pays $1,850 to insulate their home. However, the cost of insulation depends on the type, the size of your home, and who does the installation work. 

The cost of foam board insulation depends on whether it's made from expanded polystyrene (EPS) or extruded polystyrene (XPS). EPS has the lower price point, usually costing between $0.25 and $0.50 per board foot, while XPS costs between $0.40 and $0.50 per board foot.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

While there are many different kinds of insulation, spray foam, blown-in, foam board, and batt and roll are the four types you’re most likely to see. That doesn’t mean they’re alike, though. Each one varies drastically in terms of cost, materials used, and how they’re installed—not to mention, how well they limit heat transfer.

Insulating windows with plastic works, but it can be time-consuming, and the end results can—and often do—end up lacking in aesthetics. Window film and caulking your windows to make sure there are no drafts are two options that increase the energy efficiency of your home in a low-cost way. Plastic can be a good strategy while you consider alternatives.

Installing insulation helps reduce energy usage, improve home comfort, and lower utility bills by maintaining stable indoor temperatures year-round.
