"Since 7/2025 I knew we needed insulation blown into our less than 1300 SF 1973 built home. Got a quote for over $5000, left messages at many more and some didn’t even show up or return my call. On 12/16/2025 I called Angi list and was told someone would be calling me back soon(bet they want!) Well they did and I spoke Nick Martin of Martin Home Solutions and gave me a quote that I was able to pay (We are old!) and he and Jason Farmer came to our home last evening 12/17/2025!!! (Ready To Work!) We were so impressed by Nick’s honesty, open communication and work ethic. We were so very happy to know that we can survive this winter financially with adequate insulation in our attic. Call Angi List today if you are searching for someone for your attic needs, Martins Home Solutions will not disappoint."

"Was most impressed rep. Enjoyed our conversation. He was clear in describing processes; forthcoming on costs, educational on differences in products. Under other circumstances, ie, remaining in this house, would undertake insulation."

Insulation questions, answered by experts

In nearly all cases, you are required to install a vapor barrier in your crawl space. However, local regulations will change based on the local climate and the crawl space's susceptibility to moisture. Even if a vapor barrier is not legally required, it is often a good idea to keep your crawl space dry.

Structural insulated panels and rigid foam boards have the highest R-value of any insulation that contractors commonly use, with R-values reaching up to around 8.0. These types of insulation are best in extremely cold climates, but they’re generally preferred for new construction, as they can be challenging to retrofit. Blown-in and loose fill insulation provide the next best insulative value, provided the installation is done properly. It’s important to choose an insulation type that meets your needs based on climate, as maximizing R-value may not always be financially worthwhile if you live in a moderate climate.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.

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.

Insulating your home's exterior walls can realize up to a 20% reduction in your monthly energy bills. This means that regardless of how much the project costs, it can begin to pay you back immediately. Additionally, adding spray foam and other high-end materials can increase the selling value of the property.
