Interior remodeling, refinished basements, ceilings, floors and drywall. Careful attention to detail leads to a great quality of work. A team you can trust to be there when they say they will, offering fair prices with astonishing quality.

"I reached out to Supreme Interiors and received a call within an hour and a in home consultation within 48 hours. While explaining what I was looking for, Justin offered suggestions on how to make it better. He provided a fair price and scheduled me quickly. On the day of my installation, Justin was on time and started working right away. I loved the final product but I realized that I explained something incorrectly to him so I asked to change the design after the work was complete. He was so gracious and understanding which was very kind considering the circumstances. I HIGHLY recommend Supreme Interiors. Justin and his team are very professional and provide great service. I’ve already hired him for another job."

Insulation questions, answered by experts

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

Rockwool insulation can last up to 100 years, but just how long this insulation lasts in your home depends on how well it's maintained. Poorly installed insulation may last only 30 years, so be sure to regularly inspect your home's insulation for water damage, settling, and pests to give your insulation the best chance of having a long lifespan.

Yes, energy-efficient homes are increasingly desirable in the market.

2x4 walls can hold R-13 or R-15 batts of insulation, which is usually about 3.5 inches thick. You should also check with your local building codes to see if there’s a required thickness you need to adhere to. 

You can also use R-value maps to determine the best thickness and ratings for where you live. For example, someone in Texas doesn’t need as thick of insulation as someone in Montana. Energy Star has a good one you can reference.
