"Fair price an on-time service. But I should have checked the job..... there were a few spots in the attic that did not get any insulation. (not the garage..... that does not need insulation..... but a few spots over heated space were not covered). But their price was better than other estimates. I also requested the chemical that detracts rats and mice..... I do not know if it was included...... I hope so."

"Deli Brothers Insulation came to my home and did an absolutely marvelous job from start to finish. From the moment they arrived, their professionalism was clear—they were punctual, polite, and ready to get to work. Not only did they complete the insulation quickly and efficiently, but they also kept the work area spotless, which I really appreciated. Their team was extremely knowledgeable, answering all of my questions and explaining the process so I felt informed every step of the way. It’s rare to find a company that delivers both top-quality workmanship and outstanding customer service, but Deli Brothers Insulation truly exceeded my expectations. I would highly recommend them to anyone looking for reliable, clean, and expert insulation services."

Insulation questions, answered by experts

Insulating ductwork improves your HVAC system's energy efficiency by protecting the air from external conditions and preventing energy loss as it travels through the ducts. This means your system doesn't have to work as hard to heat or cool your home, leading to lower energy bills and a reduced carbon footprint. Additionally, insulated ducts help maintain a more consistent and stable indoor temperature, enhancing comfort. Proper insulation also improves indoor air quality by reducing the entry of allergens and pollutants and helps prevent problems like condensation and mold formation within the ductwork.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.

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.

Yes, many services include adding insulation for energy efficiency. Confirm with your contractor.

The best way to reduce heat upstairs is to release it by opening a window. Hot air rises, and if you can create some airflow by opening a window upstairs and also one on a lower level, the hot air should be pushed out of the home. Remember that fans pointing out the window do a much better job of circulating air than fans pointing into the home.
