"I contacted six companies for estimates to remove attic insulation, air seal and sanitize the attic, and blow in new insulation to R49 specs. Air-Tight's estimate was in the middle of the pack. Justin Wolfe, owner and CEO of Air-Tight LLC, gave me an estimate over the phone, answered every one of my follow up questions, and scheduled my work within the week. He stopped by at the beginning and end of the job. The crew did exactly what he said theyâ d do and were very mindful of my property. My neighbors commented on how nice they left the area. He even sealed an area under my steps and at the back of my home where Iâ d seen chipmunks enter and had an opportunity to sell more work when I asked him to check the attic above my garage but said I didnâ t need it and stayed with his original estimate. I recommend Air-Tight LLC without hesitation and am thankful I chose them."

"The crew at Bullseye did a great job adding additional insulation to my attic space. They got my home back up to the proper Rvalue, they also added some vents to help with air flow. Very professional and clean up was great. Can't wait to see the savings on my heating and cooling bills!"

"I am very happy with service we received. They explained the process involved very well. They worked with my schedule and performed tasks as stated. Left area involved clean. Heat is working much better in this cold snap. I would recommend this insulation company for anyone's need for insulation work to be done."

Insulation questions, answered by experts

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.

Yes, insulated vinyl siding increases the R-value of your home. Depending on the quality and brand of the insulated vinyl, you can get an R-value that is up to 5 times greater than traditional vinyl siding. This can be fantastic for homeowners who are trying to lower their utility costs.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills. 

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.
