The importance of insulation

Insulation is a very important factor in keeping your home comfortable and energy efficient, especially in Oklahoma’s climate. Proper insulation helps to keep the warm air inside during colder months and the cool air inside during hotter months. This helps to reduce energy costs because less energy will be used to maintain the home’s desired temperature. Proper insulation can also help keep your family safe and healthy.

Additionally, insulation helps to reduce outside noise, creating a quieter and more peaceful atmosphere in the home. In short, adding or upgrading your home’s insulation will give you a much more comfortable and energy efficient home and reduce noise levels.

With proper insulation and regular maintenance, your home or business will run better and more efficiently for years to come.

types of insulation

There are a variety of different types of insulation that can be used, depending on the specific needs of the home and where you need or want to install insulation to your home. Below are three of the most common types of home insulation materials.

The most common type of insulation is fiberglass, which is available in both batts and rolls. This type of insulation is made of small glass fibers and is often the most cost-effective option, and is a great choice for attics, walls, and flooring.

Another popular type of insulation is cellulose, which is made from recycled paper products. It is usually blown into walls to provide extra protection against drafts and heat loss. It is also resistant to mold, fire, and pests.

Spray foam insulation is a newer form of insulation that is becoming increasingly popular. It is sprayed onto walls and ceilings and expands to fill in any gaps or cracks. This provides an air-tight seal and excellent insulation.

There is also foam board insulation, which is made from foam and is usually cut to fit walls and ceilings. It’s a great choice for areas that need extra protection from drafts and moisture such as basements and crawl spaces.

No matter which type of insulation you choose, it’s important to make sure that it is installed properly and meets the needs of your home. With the right insulation, your home will stay comfortable and energy efficient all year round.

R-Value zones for oklahoma

Insulation reduces heat flow, and the capability of your home’s insulation to reduce that heat flow is known as its R-value.

The ‘R’ in R-Value stands for Resistance to heat flow. Typically, you will see the R-Value clearly labeled on the bags of the insulation packaging, and on the insulation material itself.

A larger R-value number reduces more heat flow. The United States is divided into 8 recommended R-value zones determined by the Department Of Energy (DOE).

Oklahoma is primarily in R-Value Zone 3, with the north-western tip of Oklahoma being in R-Value Zone 4.

Frequently Asked Questions

There are several factors that can cause insulation to go bad and stop working as it should. Extreme temperatures, moisture deterioration, insulation that is timeworn, electrical stressors such as overvoltage, and even pollutants in the air over time can cause insulation to go bad.

Our team has years of experience in the HVAC industry and can inspect and identify any areas of your home or business insulation system that need replacing or repair. Contact us for a free estimate for services today.

A few signs that your current insulation may need replacing are:

  • Musty or unpleasant odors that will not go away even after cleaning and sanitizing your home.
  • A rise in your family's allergy symptoms.
  • Constant heating and cooling issues including unexpected energy bill increases.
  • An onset of pest issues such as flies, termites, silverfish, or even roaches.


If you notice any of the signs listed above, or have other concerns about your insulation, give us call or schedule an inspection and free estimate.

The short answer to this question is yes, you can put new insulation over old insulation. However, there are a number of factors that determine whether or not this can be done in any given situation, such as:

  • Wet insulation: if the existing insulation is wet or damp, then it should be removed. Wet or damp insulation can lead to mold, mildew, pests, and other issues.
  • The type of existing insulation versus the type of new insulation: for example. "faced" insulation (insulation that has the kraft paper attached to it) should never be placed on existing insulation.
  • Asbestos: if your home contains any type of vermiculite insulation, it should first be tested for asbestos before laying new insulation over it. If asbestos is found, the existing insulation should be carefully removed.

At Mainard and Sanders Heating & Air, we have the expertise to evaluate your current insulation and determine what will be best for your home or business. A technician will explain the findings and give you options for moving forward, including a free estimate.

When most people think of weatherproofing or insulation, attics and the outside walls are the first spaces that come to mind.

In actuality, there are several spaces of the home where insulation should be installed. Some of those spaces are:

  • Basement walls.
  • Any interior wall or floor that additional sound barriers are needed.
  • Vaulted or sloped ceilings.
  • Floors that are over any area of the home that are not heated like garages.
