"Unique product making a dent in insulation market. Milex is shaped like packing peanuts so will not settle and compress like blown in insulation. Price was below some competitors we priced. Plus Texas owned company. Definitely happy with how much warmer our home feels."

"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."

"The representative was very knowledgable about the scope of work. I called him for the replacement of the attic insulation due for rats. I had pest control guy tell me my attic insulation had to be replaced. The rep, Guy, told me that wasn't what I needed. He told me that replacement the attic insulation would not solve my rats. He gave me names of good pest controls. Guy said to contact them before spending thousands of dollars for rats in my attic. Thank you Guy."

"Did a great job. Kept me updated on anything they would find while removing the old insulation and replacing with new. Showed up on time and the crew was polite and hard workers. Recommended them to my neighbor and they will have their Attic cleaned and replace their insulation also. Highly recommended."

Insulation questions, answered by experts

Insulation can be made of cellulose, fiberglass, polyurethane, polystyrene, or mineral wool. Radiant barriers are often made of aluminum or other similarly reflective materials, but they will need to be paired with something else because they don’t provide heating benefits. Cellulose is among the most eco-friendly options and may be recycled when it’s past its shelf-life, whereas polyurethane and polystyrene both emit harmful compounds and will need to be handled with care during installation.

Adding insulation to ceilings is an excellent way to increase the energy efficiency of your home. If your home's layout is such that you need insulation in the ceilings rather than in the roof, it's likely that at least some insulation already exists in the space. However, each additional inch of insulation you can add boosts the R-value by between 2.2 and 4.2.

The primary reason that insulation saves you money over time is that it reduces your energy bills by making your home more energy efficient. A crucial part of an insulation system is a properly installed vapor barrier. Local building codes dictate whether your insulation requires a vapor barrier based on the type installed. While some high-quality wool insulation may not technically need a vapor barrier, most municipalities still require one to meet code.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

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.
