"The team at NxT Level Insulation did an exceptional job with our attic insulation. Dillon was incredibly helpful in explaining the process and the crew he led was efficient and professional. We're noticing the difference already - the temperature is more consistent throughout the house, and our HVAC is running much better."

"I wanted insulation blown in above the ceiling of my condo to lessen the noise from my neighbors above. Darren was very responsive and professional and knew exactly what I was looking for. The crew arrived on time, was very nice, and covered the house in plastic sheeting to protect everything from the incredible amount of dust created by drilling dozens of holes in the ceiling to shoot the insulation. Their subcontractor Robert arrived the next day to repair the holes and repaint the ceilings. He also was able to install can lights in my living room (separate job and quote from the job Attic Construction was doing). During installation of the lights, we discovered that some of the cavities that should have been filled by new insulation were not, due to a problem with the old insulation. One call to Darren and the insulation guys showed up early the next morning to take care of it. Robert the drywall guy and his helper Carlos did an amazing job repairing all the holes, you can't even tell that my ceiling looked like swiss cheese at one point. The reduction in sound coming from upstairs is noticeable due to the new insulation and I love my new lights. Be aware though that a job like this is incredibly messy and dusty but Attic Construction OC made it as easy as possible."

Insulation questions, answered by experts

Periodic checks for moisture or pest issues ensure consistent performance.

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.

Radiant barriers and insulation serve different purposes, so one is not inherently better than the other. Radiant barriers reflect radiant heat, helping keep spaces cool, especially in hot climates, while insulation slows heat transfer through conduction. For optimal energy efficiency, it’s best to use both together. 

Radiant barriers can enhance the performance of insulation by preventing heat gain in the summer and heat loss in the winter. The choice between them depends on specific climate conditions and the building’s design requirements.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

On it own, aluminum siding has a relatively low insulation value (also called R-value); aluminum siding has an R-value of 0.61. However, you can purchase insulated aluminum siding to increase the R-value to between 2 and 5. You can also install additional insulation within your walls to help maintain temperatures within your home. On average, insulation costs $1,825 to install throughout the typical home.
