"The job was well done and very efficient. Did the large attics and basement ceiling in one day. Left the house picked up and clean. Very easy to work with. I would suggest that people are made aware of how messy and dirty the spray insulation is when done. We use the attic and had to put down plastic sheeting on top to keep it from flying around. I would recommend Dan and Shelton Insulation and Gutters without reservation."

"Anthony and his team did an incredible job insulating our full gut remodel in Fairfield. He took the time to put together a foam package that made the most of our budget. The crew was polite, neat and efficient. They took great care to cover finished surfaces before spraying and did a thorough clean up so we could jump right into sheet-rocking. Highly recommended for quality of work, constant communication and value!"

Insulation questions, answered by experts

Depending on the size, insulation condition, and removal method, it can take anywhere from four hours up to twenty hours. Therefore, be prepared to split the projects into phases, or leave it to a professional. Insulation is an intermediate project with various risk factors and can be challenging to someone unfamiliar with the process.

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.

The primary downside of radiant barriers is their limited effectiveness in cold climates. They are designed to reflect radiant heat, making them less beneficial in cooler conditions where heat retention is more important. 

Radiant barriers require proper installation to maximize effectiveness. Incorrect placement can lead to minimal benefits. They also do not provide insulation, meaning they should be used in conjunction with traditional insulation for optimal energy efficiency. 

There are many ways to keep your house cool without central air. In fact, ductless mini-split AC systems are a solid alternative to central AC for situations when you can’t install ducts in your home. If you’re looking for a more budget-friendly cooling solution, consider using window AC units or portable air conditioners.
