Attic Insulation

Insulation is measured in R-values and the higher the R-value, the more resistant it is to heat flow (and therefore the more efficient it is.) In order to know how much insulation you need to add, you should first determine the R-value of the insulation currently in your attic.

To determine the type of insulation in your attic, you need to identify whether it's cellulose, loose-fill fiberglass, or fiberglass batt, which are the most common types. The next step involves measuring the depth of your insulation in several places to get an average. 

You then multiply this number by the R-value per inch for the specific type of insulation you have. For reference, cellulose is about R3.5, loose-fill fiberglass is R2.5, and fiberglass batt is R3.5. This calculation will give you your attic insulation’s current R-value. For instance, if there's an average of 4 inches of cellulose insulation throughout your attic, your current R-value is approximately R14.

However, this process can be complicated and time-consuming. That's why at RPM Home Services, we offer to handle this task for you. Our team of experts will professionally assess your attic insulation, ensuring accurate measurements and evaluations. We are dedicated to providing top-quality service that saves you time and guarantees optimal efficiency for your home.

The frequency of replacing attic insulation largely depends on its quality, type, and the climate in your area. However, a good rule of thumb is to check your insulation every 15 to 20 years. If it's not maintaining the desired indoor temperature or if you notice higher than usual energy bills, it might be time for replacement. Additionally, signs like drafts in the house, uneven temperatures between rooms, or a ceiling that's cold in winter or hot in summer may also indicate that your insulation needs an upgrade. If your insulation has been damaged by pests, water, or mold, immediate replacement is necessary regardless of its age. Furthermore, if you're planning to renovate or remodel your home, it might be a good idea to consider replacing your insulation for improved energy efficiency. It's always best to get a professional assessment from a company like RPM Home Services to determine the right time for replacement. We have the expertise to evaluate your current insulation and advise you on the best course of action. Remember, the goal is to keep your home comfortable and energy-efficient all year round.

We use a variety of high-quality insulation materials tailored to your specific needs and home requirements. One of our most commonly used materials is loose fiberglass, known for its excellent thermal resistance and ability to fill irregular spaces. This material is blown into your attic, providing comprehensive coverage and improved energy efficiency. We also offer loose cellulose insulation, an environmentally friendly option made from recycled materials. It provides great thermal performance and is particularly effective at reducing noise transmission. Regardless of the material chosen, you can trust that RPM @ Home Team will only use the highest quality products to ensure the best results.
