Foam Insulation vs. Fiberglass: The Great DebateBy admin
Wednesday, 11 September 2019
Installing home insulation is like waving a magic wand over a property. Insulation turns a cold house into one that is warmer, safer, more secure, and more energy efficient, in just a few short hours; the benefits of home insulation are truly extensive.
Insulation is high up on the list of home improvements that are a necessity, but sadly, this doesn’t mean that the market is simple to navigate.
Pitting traditional insulation methods against modern insulation products, is all part of the challenge that homeowners face when deciding which insulation is right for their family, and, ultimately, right for their home’s individual requirements.
While all insulation methods can be compared, often, it is the debate of foam insulation vs fiberglass, that causes the most controversy.
Two very different insulation methods have a singular purpose, which makes a decision over foam insulation vs fiberglass, very difficult. The first step is take a look at just what makes the products so different in the first place, as the following article reveals…
How Do The Two Insulation Materials Work?
From texture to colour, and even design, if you didn’t know that fiberglass and spray foam insulation were designed for a similar job, it would be easy to never connect the two.
But, as understanding insulation materials is the best knowledge you can have when deciding, it is essential to compare the differences of foam insulation vs fiberglass.
Fiberglass Insulation: Plus Points And Pitfalls
Fiberglass comes in two forms, batt insulation and loose fill insulation, both of which have very different designs. The batt form is rolled out, while the loose fill is blown into spaces; this must be done carefully to avoid the possible dangers of fiberglass insulation.
Normally both consist of a similar material composite, a combination of glass fibres and plastic, with the plastic present to reinforce the glass. In many cases, a good proportion of the materials are recycled, helping the product to be eco-friendly.
Foam Insulation: Plus Points And Pitfalls
Spray foam insulation is at the complete opposite end of the spectrum when it comes to home insulation, and has been featured in some spectacular modern builds. The material itself is a 100% water-blown product, and comes in two forms: open-cell and closed-cell.
Unlike fiberglass, these are a lot more similar in appearance but very different when it comes to properties. All forms of spray foam are sprayed onto a surface, or pumped into gaps, expanding to fit the needs of the area for optimum heat retention.
Spray foam is an excellent attic insulation, able to form strong air seals alone, but can also be used in cavity walls for great moisture resistance, under floors, in ceilings, and in crawl spaces. Fiberglass is a little more limited, with batts only really being able to be laid, and loose-fill having to be secured
Foam Insulation vs Fiberglass: Which Is Best?
Initially, there are a lot of differences between the products, but for a full look at the foam insulation vs fiberglass debate, the properties have to be considered as well.
The main properties reveal quite a bit about why homeowners choose one product over another. The comparison starts with the R-value of the products, this determines how efficient the insulation will be.
The two types of spray foam have two R-values; open-cell has a value of 3.6 per inch, and closed-cell has a value of between 5.5 and 6.5 per inch. In contrast, fiberglass comes in significantly lower; batts have an R-value of 3 per inch and loose-fill has a value of between 2.2 and 2.7 per inch.
The next consideration is the install method, with the properties of each giving limitations to where they can be used and how effective they will be.
Spray foam is an excellent attic insulation, able to form strong air seals alone, but can also be used in cavity walls for great moisture resistance, under floors, in ceilings, and in crawl spaces. Fiberglass is a little more limited, with batts only really being able to be laid, and loose-fill having to be secured.
However, it still makes a good and affordable insulation material, when installed by experts.
Is Spray Foam Replacing Fiberglass?
While for many fiberglass is one of the first insulation materials to spring to mind, in recent years, it seems that many homeowners are making the switch to spray foam insulation.
Customers Mr and Mrs Brittan, who replaced their fiberglass insulation with spray foam commented: “We had the icylene [Icynene] spray foam installed by Homelogic in mid-August. The staff and installation team have all been very courteous, helpful and efficient. The two installers removed all the old glass fibre insulation, did the installation in a couple of hours and cleaned up very well on completion.”
This shows that it is not just new customers that the debate over foam insulation vs fiberglass is important to, but those that have already invested in insulation in the past.
At Home Logic, we believe in the efficiency of spray foam insulation as a modern solution to heat loss for every home.
