Denver Fiberglass Insulation

Insulation Company Installing Fiberglass Insulation in Denver, Fort Collins & the Colorado Front Range

Fiberglass insulation is one of the most common materials used to seal and insulate homes. Originally introduced in the 1930s, it is still used today as an affordable and effective insulation option for new homes and retrofitting projects.

Although you can pick up rolls of fiberglass insulation at your local hardware store, many homeowners find it difficult to upgrade home insulation on their own. REenergizeCO can help you realize the full benefits of upgraded insulation without the hassle of doing it yourself.

Please call REenergizeCO in Denver at (303) 227-1000 or in Fort Collins at (970) 323-3191 today. Our insulation experts handle jobs throughout the Front Range of Colorado.

What Is Fiberglass Insulation?

Fiberglass insulation is composed of many fine, densely packed fibers of spun glass. There are two primary forms of fiberglass used to insulate homes:

Rolls and Batts

You’ve likely seen rolls or batts of fiberglass insulation before. Batt insulation is rolled up like a rug and packaged as a single sheet. The insulation is then cut to size and fitted inside walls, ceilings, and floors and along doors and windows.

Generally, fiberglass batts are installed during construction. However, rolls can also be added to an existing home (although this will require opening up the wall).

Blown-In Insulation

Loose-fill or blown-in insulation consists of small pieces of fiberglass or other materials. It is installed using a hose that is connected to a machine that blows the particles of insulation into the treated space.

Blown-in fiberglass insulation expands as it is sprayed. As the material settles, it forms an effective thermal barrier. Loose-fill fiberglass is an effective complement to existing insulation, particularly in attics.

How Does Fiberglass Insulation Work?

All insulation materials are assigned an R-value. The R-value is a measurement of the material’s resistance to thermal energy.

Read More: How Is Insulation Rated?

When installed strategically inside the house, materials with a high R-value (like fiberglass) help prevent hot and cold air from infiltrating your home and seal air leaks. As such, proper insulation is essential for maximizing the energy efficiency and comfort of your home.

The R-values you see on packages of insulation are calculated by dividing the material’s resistance to heat flow by the thickness of the material. Fiberglass rolls and batts are thicker than blown-in insulation, so they have a higher R-value per inch. However, loose-fill insulation can augment existing materials for a higher overall R-value.

Where Can I Use Fiberglass Insulation?

Fiberglass insulation can be used in multiple places inside your home. During new construction, it is often installed along the beams of the ceiling, between the studs inside of the walls, and along the floor joists.

In addition to insulating new houses, fiberglass can also be used to improve existing home insulation. Retrofitting can be done in a number of different areas of the home, including:

Generally, it is unnecessary to remove existing insulation before adding new fiberglass batts or loose-fill. New insulation can be added with minimal disruption to existing walls and other spaces.

What R-Value Do I Need?

The R-value needed to properly insulate a space depends on the local climate. According to the International Energy Conservation Code, the Colorado Front Range is a Cool Dry climate.

Recommended R-values vary depending on which parts of the home are being insulated. In Colorado, the R-values you need for home insulation include:

  • R-49 in attics
  • R-19 in crawl spaces
  • R-13 on exterior walls
  • R-11 in basements

Fiberglass batts and rolls can provide the necessary insulation in new and existing homes. Alternatively, retrofitting with blown-in fiberglass insulation can make up for underperforming insulation by adding to the existing material in your home and pushing up the overall R-value.

Benefits of Fiberglass Insulation

Insulation is crucial for the energy efficiency of a home. When your home is properly insulated, you save money on energy bills and enjoy greater comfort throughout the house.

Fiberglass insulation can help you reach these goals. Other benefits include:

1. Low Cost

Affordability is one of the principal benefits of insulating with fiberglass batting or loose-fill materials. It is less expensive than the other materials that are commonly used to insulate homes. This includes options such as cellulose and mineral wool.

2. Longevity

Fiberglass insulation also lasts a long time. Under perfect conditions, fiberglass stays viable for the life of your home.

That said, it is important to be aware of issues that can damage insulation and reduce its effectiveness. Problems that can affect longevity include:

  • Displacement
  • Moisture – water damage can degrade fiberglass particles and lead to the growth of mold and mildew
  • Animal activity
  • Excess insulation, resulting in premature failure

Issues like these will require removing insulation before new material can be added. However, in our experience, insulation removal is typically not necessary when it comes to retrofitting projects.

3. Quality Installation

The two different types of fiberglass insulation provide multiple options for properly insulating spaces inside the home. Fiberglass rolls can be precisely cut to fit inside walls and snugly cover joists in the floor and ceiling. With proper measurement and some simple addition by a professional insulation contractor, blown-in fiberglass can enhance the R-value of a conditioned space.

4. Fire Resistance

Fiberglass is naturally nonflammable. As such, you can insulate your home without being concerned that the material will catch fire. (That said, it is important to keep the paper or foil backing on fiberglass rolls away from ducts and electrical wires.)

5. Noise Reduction

Although it doesn’t provide soundproofing per se, fiberglass insulation can cut down on the outside noise that enters your home. This is especially true of fiberglass batting.
