"The owner of the company did my estimate, and was wonderful in explaining things, and at no point did I feel I was being up sold or steered in any direction. The two installers were pleasant, quiet, worked clean and quickly. They left the house as clean as it had been when they arrived, and I am already appreciating a change in the air temperature in my upstairs. I would completely recommend Superior Insulation."

Insulation questions, answered by experts

Without a doubt, insulating a garage door is a surefire way to make your home more energy efficient. Not only does insulating your garage door reduce your electric bills, but it also helps protect your valuables inside your garage, all while making for a quieter interior space. 

In regions that drop below 0 degrees Fahrenheit, your car's battery is at risk of malfunctioning in a garage that drops dangerously low. So, homeowners who reside in extremely cold climates can especially benefit from insulating their garages.

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Not necessarily. A higher R-value simply means that the insulation has a higher heat resistance and performs better in terms of how much heat passes through the material. This can be better for some homes, or it can be too high of an R-value for other homes. Again, your climate zone determines whether the insulation is better for your home.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

The cost to install or upgrade insulation generally ranges from $1.50 to $4.00 per square foot. The final price depends on factors such as the type of insulation chosen, the total area to be covered (home size), and local labor costs.
