Insulation Frequently Asked Questions (FAQs)

Insulation is typically installed in walls, attics, ceilings, and floors to reduce heat flow. It helps keep warm air inside during winter and cool air inside during summer, keeping your home comfortable and reducing heating and cooling costs. 

Insulation works by trapping air in small pockets to slow heat transfer. This helps keep your home warm in winter and cool in summer. The effectiveness of insulation is measured by its R-value, which indicates how well it resists heat flow.

Insulation can be made from materials like fiberglass, cellulose, spray foam, or foam board. Each type offers different benefits based on cost, performance, and installation. At Larson & Keeney Home Services, we are a certified Dr. Energy Saver installer and we use premium Dr. Energy Saver cellulose insulation that is both thermally efficient and fire-retardant.

Cellulose insulation is made from recycled paper and treated to be fire-resistant. It’s a great option for eco-friendly homeowners. This type of insulation is effective at filling gaps and preventing air leaks.

The amount of insulation you need depends on your climate and the area you are insulating. For example, in attics, the recommended R-value is between 38 and 60, while walls need an R-value of 13 to 21. A professional inspection is recommended to determine the right amount of insulation for your home.

In most homes, it’s recommended to have 12 to 18 inches of insulation in the attic. This ensures that your home stays at a comfortable temperature and is energy efficient. At Larson & Keeney, we can inspect your attic and recommend the best insulation solution for your needs.

For attic spaces, blown-in cellulose or fiberglass batt insulation is a great choice. These materials work well to fill the spaces between rafters and prevent heat loss. Spray foam insulation is also an option for superior air sealing, which can provide even better insulation.

Fiberglass batt insulation is commonly used for walls because it is cost-effective and easy to install. However, spray foam is another good option if you need superior air sealing and more energy efficiency.

Fiberglass batt insulation and spray foam are both great for ceilings. These materials prevent heat from escaping, keeping your home energy-efficient and comfortable.

In Milwaukee, where winters can be cold, insulation with a high R-value is important. Fiberglass batt, cellulose, and spray foam are great options. Our team ensures the right product and installation to keep your home energy-efficient during harsh weather.

For cold winters in Milwaukee, blown-in cellulose and spray foam insulation are recommended. Both provide excellent air sealing and thermal resistance, keeping your home warm and energy-efficient.

The cost of insulation depends on the material and the area being insulated. Generally, blown-in cellulose or fiberglass batt are more affordable options, while spray foam insulation may be more costly but offers better energy savings over time.

Yes, spray foam insulation is safe when applied correctly. It is made from non-toxic chemicals and expands to fill gaps, offering excellent air sealing and thermal resistance.

Fiberglass insulation is generally safe but can irritate the skin and lungs if handled improperly. Our professionals wear protective gear and use proper tools to ensure safe installation. Once installed, fiberglass insulation poses no significant health risks.

Most insulation materials are fire-resistant, including fiberglass and cellulose. Spray foam insulation is also fire-resistant, but should be installed carefully to avoid any potential hazards.

No, fiberglass insulation is non-flammable. It’s made from glass fibers and does not catch fire. It is a safe option for homes when installed correctly.

Yes, fiberglass insulation is made from fine glass fibers. It is one of the most common types of insulation due to its effectiveness and affordability.

Fiberglass insulation can last for over 30 years, while cellulose insulation typically lasts about 20 years. Spray foam insulation can last up to 80 years with proper care and maintenance.
