But there's no denying that fiberglass insulation is extremely popular - in fact, the longstanding most popular insulation material on the market. Almost everyone who decides to insulate their attic, crawl space, room addition, or other part of their building at least considers using fiberglass. And most of the time, fiberglass becomes their final decision.

Read on below to learn why fiberglass insulation is so popular, what it's made of, where are the best locations to have it installed, and other important information on the topic.

Why Should You Install Fiberglass Insulation in Your Home or Business?

hvacmaintenance e1547224414355

Saving money on your power bill is a huge motivation for Los Angeles Area home and business owners to insulate their buildings with fiberglass, and the savings and benefits accrue all year long - not just during the hottest and coldest months.

But why is it that fiberglass is by far the most common insulation choice?

There are many reasons for fiberglass's dominance, but there's no denying that it's preeminent affordability is at the top of the list. Using fiberglass saves you money on upfront insulating costs. And for most situations, fiberglass is fully adequate to the task, having sufficiently high R-values and long durability.

Another reason fiberglass is dominating the market is that it's very easy to handle compared to some other types of insulation. It's relatively lightweight and comes in preformed batts you can roll out. Or, it can be blown into your attic, ceiling, or wall - and with well equipped trucks with powerful blower machines, loose fill fiberglass insulation can be installed relatively quickly.

Sometimes, a vapor barrier may be needed as well (as in a crawl space) to prevent moisture build-up on it. But in most instances, the paper backing on the fiberglass is a sufficient vapor barrier in itself. Plus, fiberglass is resistant to moisture, mold, and mildew.

Fiberglass is fire resistant, non-conductive of electricity, a noise-reducer, and will also help keep contaminants out of your indoor air.

However, fiberglass can be itchy if it contacts the skin, and it has to be installed with care to ensure maximum insulating power. These are good reasons to rely on a professional insulator to handle the insulation task.

What Is Fiberglass Made Of?

"Fiberglass" is a kind of plastic material that is reinforced by tiny "glass fibers" that give the material greater strength.

In many cases, the glass fibers are made out of recycled glass, so fiberglass can be good for our environment.

Normally, fiberglass insulation comes in either rolls of paper-backed batts or as loose fill insulation to be blown in.

The R-value of fiberglass is high, meaning that it offers greater "thermal resistance" than many other materials; and this of course is why fiberglass is such a great insulation choice. It is relatively dense and thick with a good deal of air pockets in it - however, other insulation types will often have a higher R-value than does fiberglass. But for the price, and if you need only "normal" levels of insulating power, fiberglass is the perfect material to use.

Fiberglass Compared to Other Insulations


How does fiberglass stack up against other insulation types? On price point, it's the lowest.

On R-value, it is higher than cotton (denim) insulation. Cotton and fiberglass are actually close on R-value, and people who choose cotton often do so because it is an all natural product, fully recycled, and wont' get you itchy when you touch it.

Fiberglass also has a similar R-value to many cellulose insulation products. Cellulose is made of recycled newspapers or another paper product and is treated with borate and other chemicals to make it fire, moisture, mildew, and pest resistant.

There are also other insulation types, like mineral wool or spray foam, which cost a lot more to install, though the R-value is high. And there is soundproof insulation, which is some of the thickest, most energy efficient material around (and it also costs much more than does fiberglass.)

Will Fiberglass Insulation Cause Cancer?

Anyone who has talked to others about fiberglass or who has Googled fiberglass online may well have the question, "Does fiberglass really cause cancer?" in their mind.

The fact is, there is not real proof that fiberglass is a cause of cancer. There really isn't any evidence for it causing cancer in humans either. There were some studies done on rats where fiberglass fibers were implanted in the rodents' lungs and it increased the risk of cancer, but the manner in which the fibers were implanted is suspect and makes these studies very controversial and inconclusive.

That said, frequently touching fiberglass on your bare skin or inhaling it is not healthy. You can get skin rashes, excessive itchiness, and have respiratory problems in extreme cases. That's why one needs to wear gloves, pants and a long-sleeved shirt, goggles, a face mask, and full protective gear when installing fiberglass insulation. And that's also one reason why many opt to have a professional company like Pure Eco handle the installation process for them.

One shouldn't have open-faced fiberglass (not paper backing or loose fill) in a room that will be in constant use; but no one does that anyway, so it's not really an issue. If you exercise proper safety precautions and use common sense, fiberglass insulation is perfectly safe to use.

The History of Fiberglass


Today, residential/commercial building insulation is the primary use of fiberglass material, though it is also used in automobiles, boats, tents, curtains, and more.

But the idea of fiberglass is not new. Even in ancient Egypt and Phoenicia, they were using a kind of fiberglass insulation (tiny glass fibers woven into a coarse material.)

It was in 1932 that today's fiberglass product was discovered. And rather than necessity, it seems to have been accident that was the mother of this particular invention. Researcher Dale Kleist accidentally split a stream of molten glass into numerous small fibers with a shot of pressurized air. By 1938, he had perfected the manufacturing method and started a company called "Fiberglas®."

At first, the product was used in seemingly everything but insulating building, and especially in certain automobile parts. It was only decades later that it became popular as a home insulation product, and it has remained so ever since.

Where Is It Best to Install Fiberglass Insulation?


You can use some form of fiberglass insulation pretty much anyway in your house that insulation is needed. However, the attic, crawl space, and walls and ceilings are the major areas to be sure you have covered.

But how much insulation to put in each location, how high of an R-value you need there, and whether batts or loose fill is best, all varies.

Anywhere that you have evenly, standardly spaced studs or rafters, batts insulation should fit snug between the wood and fill in the space sufficiently well. But for non-standard spacing, loose fill insulation is often a better choice.

On an attic floor, loose fill insulation is often used because it can be made to fill in spaces more compactly than can batts; but that's not to say batts can never be used on attic floors either.

In extremely tight spaces, you should consider opting for loose fill; because you never want to squish fiberglass batts insulation to make it fit into cracks and crevices. Of course, we can cut the batts fiberglass and carefully fit it into many small spaces, but in some instances, you almost have to go with loose fill material.

Next, when it comes to walls, you often don't need as high an R-value as with, say, an attic ceiling. The reason is that the siding, plywood, and drywall with also contribute to the overall R-value of the wall - so an 11 might rise to a 14, for example, when insulation and all other materials are taken together. Plus, heat rises and accumulates at the attic ceiling, trying to escape; but that's just not the case with walls. But a prevailing wind facing wall could do well to have a little extra R-value added into it.

Finally, your geographic location also affects how much insulation you need. In the L.A. Area, you don't need as much as in northern Wisconsin or Canada, of course, but you do need enough. And you do want to create a heat envelope that covers the entire house; plus, remember that keeping the cool in and heat out is as much a function of insulation as the opposite.

The Process of Installing Fiberglass Insulation


At Pure Eco, we always install your fiberglass or other insulation product in strict accord with manufacturer's instructions and so as to obtain and long retain the highest possible R-value for your home or business property.

We can give you an accurate quote over the phone, but an on-site inspection may be needed to get an even more precise quote.

After inspecting the are to be insulated, we may need to first clean it to prepare it for the insulation. And we will need to check for drafts and air leaks, large and small, and air seal the area before laying the insulation down. Unless air sealing is done first, you are losing a good deal of the energy efficiency that new fiberglass insulation can bring to you building.

If we find mold, mildew, rotted out rafters, or other problems, we may need to fix that first.

The insulation itself is, with batts, rolled out and cut precisely to size. Then, we gently and carefully insert it into the wall, ceiling, or floor space it will cover between the rafters or studs. We firmly attach both edges to the wood so it will not move. And then we overlap the flaps to create a seamless barrier across the insulated area.

In the case of loose fill fiberglass insulation, our insulation truck will arrive with its powerful onboard blower machine. We will run the hose to the area to be insulated by the shortest possible route. We blow in the insulation from one side of the attic floor or other area to the other, and we ensure that it is filled in completely, compactly, and evenly.

I already had my main attic done last year by a different company that did not do what they said they would and ended up damaging my ceiling. Decided to go with a different company this time around for a smaller attic of an addition that isn’t directly connected to the main attic.

The attic had no insulation at all (built in the 1930s). It needed debris vacuumed out, rodent proofing, and R-38 batt insulation.

After getting quotes from several folks, decided to go with Pure Eco. Quick turnaround, reasonably priced, good professional crew lead by Martin, and clear communication through my assigned contact Jasmine. Discussion and quote was based on photos I took. Contract and payment was handled all through e-doc services. And they made sure to give me an overview of the work done before leaving. The difference in temperature was a noticeable improvement that night.

Highly recommend.

Our home needed some serious insulation and duct work done. It was awful and quite old (the insulation shrunk to approximately 3″). We called three companies for a quote, and we only saw two. We decided to go with them, before seeing the third, because of the amazing deal they offered and because they would be able to do it immediately. Ben was our sales guy and he was more than helpful and extremely knowledgeable. He made sure to inform us that they are licensed, bonded, and have workers’ compensation insurance, which kept me at ease.

The following day was the installation. Ben told us that they would be there from 8AM – 7PM (latest). They arrived on time, and completed the job by 3PM!!! I was shocked and thoroughly pleased. William, the supervisor of our job, was extremely friendly, and his crew was very professional. They cleaned up their mess; it looked as clean as when they arrived.

I highly recommend them and think that anyone that uses them will do so as well. Hi

I am a firm believer in referrals from friends when it comes to anything for my home and this company was a good referral for sure. My husband and I love Pure Eco and would definitely recommend them to everyone.

They have very professional installers and managers. Everything went smoothly from the scheduling to the end of the job. They use new machines and trucks (I tend to judge a book by it’s cover, unfortunately).

We had them replace our duct system and they installed Radiant barrier. They came in and did their job and left with no mess behind. Definitely give them a try!

We recently bought a house in Canyon Country and the garage was completely exposed and got extremely hot this time of year. When it was 90 degrees outside, the garage was well over 100 degrees. I got quotes from about a half dozen companies but was the most impressed with Pure Eco, especially their representative Sara. She was very helpful and she worked with me on the quote and gave me a lot of of great suggestions as to the best way to get our garage as cool as possible while staying within our limited budget. She recommended insulating the ceiling and front gable and then putting in radiant barrier. Her team came out and did the job in one afternoon and cleaned up afterwards. And now our garage is a LOT cooler. I can definitely recommend Pure Eco.
