"The GIC team was very prompt and knowledgeable. They were very neat and cleaned up well after themselves. We had our attic insulated and foam sprayed on rim joist and basement crawlspace. We noticed the house to be much quieter immediately. So glad we had this done in January before the -22 degree temperatures hit. Can't wait to see the effect on summer air conditioning bills."

"I highly recommend Insulation Pros of KC for your insulation needs. Kyle the Sales Manager: made it easy to understand what I needed. Josie the Office Manager: took the time to answer my questions when I called, and was the one responsible for my decision to go with Insulation Pros. The installation crew: Devon, Tyler and Leo were a great team to work with, very personable and just all around nice guys who did a great job with the installation. Tanner - the Production Manager, who came by to see that everything was going like it should. From the first meeting with Kyle, to the time the crew drove away, it was easy and pleasant to work with this company and they did a great job. Attached are pictures to show the 22" of insulation in my attic! :)"

"We had 1 inch of insulation in our attic. Hired the fellas at Green Star Energy to blow in insulation throughout the whole attic. I felt a difference immediately once the project had been completed. Our ac is getting a much needed break."

"My experience with Victory Insulation went extremely well. They installed blown fiberglass insulation in my attic. The installation crew was very helpful and easy to work with. Since the install, my family has already noticed our hvac running a lot less within the last few months. I highly recommend working with Victory."

Before we started you could see the ceiling joists. We made sure this insulation was up to EnergyStar recommendations, R49 (about 18" of blown fiberglass insulation).

Insulation questions, answered by experts

It is usually possible to install insulation yourself, but it’s often better to hire an insulation professional. An experienced insulation pro can determine which type of insulation is best for your space and the R-value get the most value and comfort in your home. Certain types of insulation can cause skin, eye, and lung irritation, and a professional will have the equipment necessary to keep themselves safe and limit the effect on your indoor air quality after the installation. Certain types of insulation—like blown-in and loose-fill insulation—demand a professional for proper functionality and safe installation.

Glass fibers are often used in HEPA filters because of their high efficiency, durability, and thermal stability. Some HEPA filters are made with synthetic fibers, but they may not be as effective. While there is some fiberglass shedding, as long as the HEPA filter is intact and not cut open, the amount of fiberglass released by a HEPA filter is well below the breathable particulate matter.

A DIY blown-in insulation project in a typical attic should take you no more than a week to complete. Experienced homeowners can blow an entire attic in one or two days.

Yes, eco-friendly blown-in insulation options include materials made from recycled cellulose or wool. These offer excellent thermal performance and sustainability, reducing energy consumption and environmental impact while enhancing home efficiency.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.
