"Our home was built in 2016, but not to our specifications. The builder did just the minimum R-34 insulation in the attic, causing the HVAC to run constantly most of the year and the home could not hold its temperature (set to 73 but rose as high as 80 degrees). I sent a request to TLS and (surprisingly) got a call back within minutes from the owner Seth who, despite being on the road in Texas acquiring new trucks, spent a solid 15-20 mins on the phone to understand my situation. His product type is above standard and his prices are extremely fair, so set an appointment. Two weeks later, his brother Tom arrive 10 minutes EARLY for the appointment and his crew quickly knocked out the job in less time that they estimated. Since then our home (now with R-50+ attic insulation) stays cooler, has less humidity and the HVAC isn't working as hard. Hats-off to Seth & Tom at TLS Insulation! I highly recommend this company!!"

"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."

"They came out to inspect my property. They told me I didn’t need their services and my house was insulated more than enough. They could’ve sold me the world, instead they were extremely honest and polite. Their prompt and professionalism is unsurpassed and I would recommend them with all my heart"

"I had an amazing experience with this spray foam insulation company. From the first phone call, they were upfront, honest, and very knowledgeable. The crew showed up exactly when they said they would and walked me through the whole process before starting. They insulated my attic and part of my garage, and the difference was noticeable the same day ? the rooms stay cooler, and the AC doesn?t run nearly as much"

Insulation questions, answered by experts

Monolithic slabs don’t require insulation, but many homeowners choose to have their contractors install insulation under the slab during construction. This can help improve home efficiency even more and keep indoor temperatures more stable. Slab foundations are more energy-efficient than uninsulated crawl spaces and basements, and insulated slab foundations are more energy-efficient than insulated crawl spaces and basements.

If you feel your energy bills are too high or your HVAC system is working harder than necessary to maintain the correct temperature in your home, you may have an under-insulated home. If you’re unsure, consider having your system’s efficiency assessed by a local independent energy auditor.

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.

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

In addition to adding insulation to your attic, you may want to add a radiant barrier. A radiant barrier works by using reflective material, such as foil, on the attic floor. As heat penetrates the roof and enters the attic, the radiant barrier reflects the heat upward and back through the roof. If you receive a lot of direct sunlight on the roof, using both a radiant barrier and insulation in your attic can provide significant benefits.
