"I had 1700 sf of attic space insulated and air sealed in a two attic, tri-level house. Ryan was absolutely awesome. He was very knowledgeable and answered everyone of my questions...I had a lot. They showed up early to every appointment. Once the job was completed, they did an awesome job cleaning up and vacuuming with their HEPA vacuum. I would highly, highly recommend these guys. They also filled out the Xcel rebates for me and subtracted from my bill. AND, they did a blower door test to validate the air leakiness of my house. They were able to reduce my leakiness by 52%!!! The next day, I could feel the difference already!"

"Guardian Insulation was great to work with. Everything was explained in depth and choices broken down with plenty of info. We already feel a difference and notice that our furnace isn't running as often, even though we are in a cold spell. They cleaned up too. Would highly recommend!"

Jason Montgomery was most timely making his bid and then completing the work as promised on time. The crew did a very complete -tidy and clean- job and I appreciated his consultation and overall knowledge of the requirements for the project.. I certainly do Recommend Montgomery Insulation !

Insulation questions, answered by experts

Insulating a detached garage won't reduce your home's heating or cooling bills—and insulating an attached garage will only have a small effect on your home's energy efficiency. However, insulating an attached garage can reduce the transfer of heating and cooling to and from the outdoors, which can reduce the amount of energy your home needs to stay comfortable. Also, having an insulated garage is just more pleasant. Balance the cost of insulating your garage with how you'll use the space to determine if the project is worth it.

Insulating windows without plastic is usually the better method. Outside of simply replacing your windows, you could buy cellular shades, which trap air between the window and the home, add a window film that blocks UV rays and traps heat, or cover your windows with a low-emissivity coating called “low-E.”

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.

Traditional clapboard siding, particularly with panels made from wood, is not a significant insulator on its own. However, you can keep your home cooler in summer and warmer with "insulated clapboard siding," which is a type of vinyl clapboard siding with a built-in foam insulation. Consult a local siding contractor to determine whether insulated siding is right for your home.

For standard 2x4 walls, the ideal insulation has an R-value between R-13 and R-15. This level of insulation, typically around 3.5 inches thick, fits well within the wall cavity. Common options include fiberglass batts and spray foam. The best choice for your home can depend on your climate; use R-value maps, like those from Energy Star, to determine the recommended level for your region. For colder climates, you might also consider adding exterior insulation for greater efficiency. Always check with your local building codes to ensure you meet any required standards.
