Blown-In Insulation: The Tried and True way of Insulating

Blown-in insulation (sometimes called blow-in insulation) comes in bags and is loosely filled blotches of fiberglass that insulate your home. It largely resembles the lumps of cotton found inside pillows. It’s called blown-in insulation because it is most commonly blown into an attic through a special insulation blower, which has a long, wide hose that shoots the insulation through your attic like snow.

Benefits of Blown-In Insulation 

Cheaper Initial Cost

Blown-in insulation is generally less expensive than radiant barriers, both in terms of material and installation costs. 

Noise reduction

Blown-in insulation can help reduce sound transmission from outside the home, while a radiant barrier does not provide any soundproofing benefits.

Flame Resistance

Blown-in insulation can provide better fire resistance, as blown-in insulation typically contains fire retardants not found in radiant barriers. 

Keeps Heat In

Blown-in insulation can be more effective than a radiant barrier during the colder months, as it can help retain heat in the attic and in turn the home when it’s cold out. Unfortunately, this benefit can sometimes be a problem in the warmer months.

How Insulation R-Value Works

R-value is determined by installing the number of bags per 1000 square feet to the desired height in inches when the insulation is settled and at the desired weight, determining the density. Green Energy of SA installs R-30 fiberglass blown insulation, which is 10.25 inches tall throughout your attic, with a weight of no less than .436 pounds per square foot.

The maximum that one bag can cover for R-30 insulation is no more than 65.4 square feet. Insulation is not sold by the inches, it’s sold by the amount of bags it takes to fill your attic up to the specified (R-30) R-value. Basically, the higher the R-value, the better the insulation. The R-30 insulation we use, for example, is better than R-19 insulation.

If a San Antonio insulation installer covers your attic with less than the minimum number of bags it needs, your attic will have a lower insulation R-value, which means you won’t get the same energy savings during the hot Texas summers. At Green Energy of San Antonio, we guarantee a quality job, with R-30 insulation properly installed in your attic.

We are very pleased with the radiant barrier we had Green Energy install in our attic. We have definitely noticed a difference in the closets that the attics are connected too. We had an issue with the upstairs AC unit after install and Green Energy responded immediately even though it was after 8pm. The issue was resolved quickly and efficiently. Personal and responsive, professional service. The value will continue to tally up as the years go by. Thank you to the Green Energy team!

We had a mid-grade radiant barrier installed and also had some insulation blown in over our garage, which has never had any the entire time that we have lived in this house. They did an excellent job and I can definitely notice a difference in how much less hot it gets in our garage now. It’s still pretty toasty but not hot enough to bake a cake out there anymore!! We are VERY satisfied with the work that we had done, and would definitely recommend Green Energy to anyone!!! 😁 👍

Mr. Ramos and his grandson came out to talk to us about a radiant barrier and were very professional and  courteous. Really appreciated them giving us options that were in our best interest and not theirs. Needless to say, we were very satisfied with the installation and the product. It’s been three months and we haBe already saved over $200!! I would definitely recommended homeowners to give Mr. Ramos a call if your looking into radiant barriers for your home.

Six years ago Green Energy installed my radiant barrier, blown-in insulation, and a couple solar powered attic exhaust fans. They did a terrific job and I am still super happy with the outcome. I combined all of this work with replacing my single pane windows with double pane. Immediately my monthly average electric bill dropped from about $425 to about $220 and has remained in that range ever since!

Last week I called them regarding a warranty question. The phone was answered immediately and I received nothing short of superior support. I cannot express exactly how happy I am with Green Energy, even six years after installation!

I had Green Energy of San Antonio come in and install Radiant Barrier, Soffit vents, and install a ridge vent on my house. They did an excellent job! My house was instantly cooler, and my HVAC system actually turned off. It usually runs non stop during the day because of the temperature outside. Thank you so much for everything!


Radiant Barrier: The Ultimate Attic Insulation Solution

Radiant barrier insulation, a cutting-edge technology in attic insulation, is transforming how we insulate our homes. Installed beneath the roof, it's designed to reflect radiant energy, significantly reducing heat penetration into the attic and the rest of the house. This modern approach contrasts with traditional blown-in attic insulation, which primarily slows down heat transfer rather than reflecting it. However, when these two methods are combined, they create the ultimate insulation solution. The radiant barrier's ability to reflect up to 97% of radiant heat complements the heat-slowing properties of blown-in insulation, providing a comprehensive and highly effective barrier against heat transfer. This synergy marks a significant advancement in attic insulation, much like the evolution from flip phones to smartphones revolutionized communication technology.

Benefits of Radiant Barrier

Thermal Reflectivity

Radiant barrier reflects up to 97% of the sun's radiant heat, while blown-in insulation only absorbs and slows heat down. 

Energy Efficiency

Radiant barrier can help reduce the amount of energy needed to cool your home, as it keeps the heat out during the summer months.

Increased Lifespan

Radiant barriers can last for up to 25 years, whereas blown-in insulation may need to be replaced after just a few years.

Reduced Maintenance

Radiant barrier does not require any maintenance, while blown-in insulation may need to be adjusted or replaced over time.
