Is spray foam insulation any good?
Spray foam insulation is a great product. Homes insulated with it can be some of the most efficient and comfortable homes built. Spray foam comes in two flavors, open cell and closed cell, and provides both parts of the building envelope – the insulation and the air barrier.
How much does it cost to insulate an attic in Ireland?

Is spray foam insulation cost effective?
Spray foam insulation is typically two to three times more expensive than cellulose or fiberglass insulation. Spray foam insulation does cost more than traditional options, but over time it pays you back in energy savings, and you can’t really put a price on the comfort of your family.
What are the disadvantages of spray foam insulation?
- The upfront cost is higher than conventional insulation.
- Payback period is 2-4 years.
- It is not generally a Do-it-Yourself project.
- The installation process is longer.
- The process could be messier.
What are the pros and cons of spray foam insulation?
The “ pros ” of installing spray foam insulation
- air leakage is virtually eliminated.
- an air-tight seal prevents heat loss.
- home energy efficiency is assured.
- seasonal energy bills are lowered.
- ideal for attics, roofs, walls, floors.
- higher R-Value than other installs.
- moisture accumulation is reduced.
Where should you not use spray foam insulation?
When NOT to Use Spray Foam Insulation
- For areas that are too close to electrical boxes:
- For areas too close to ceiling light boxes:
- Open-cell spray foam on your roof:
- For closed-cavity spaces:
- If you have a history of skin, respiratory, or asthma problems:
Can mice eat through spray foam insulation?
Spray foam insulation is in no way a repellant. Mice, bats, rats, and other pests can chew through wood to get into and out of your home. So, of course they can chew through the foam.
How many years does spray foam insulation last?
The International Association of Certified Home Inspectors states that spray foam insulation, wrap tape and housewrap insulation can last for more than 80 years. At the same time, cellulose, loose-fill, foamboard, loose fill and rock wool insulation can last up to 100 years.
Can mold grow on spray foam insulation?
Spray Foam Insulation to Prevent Mold Unlike other insulation materials, spray foam is water resistant, meaning it keeps that dangerous moisture where it belongs: outside. As an added bonus, spray foam forms an airtight seal.
Can you put too much insulation in attic?
It is possible to over- insulate your house so much that it can ‘t breathe. The whole point of home insulation is to tightly seal your home’s interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers. That’s when mold starts to grow.
How much does it cost to insulate a 1200 sq ft attic?
On average, most homeowners spend between $813 and $1492 or $1.50 to $3.00 per square foot to install attic insulation. Pricing depends on the size of your attic, the type of insulation material used, and labor rates. For example, blown-in insulation for an attic in a 1,200 square foot home costs about $1,850.
Which is better spray foam or insulation?
R-value is a simple “the higher, the better ” statistic. On paper, spray foam is the clear winner in this category, as closed cell foam can reach staggering R-value heights of up to 7.0. It also doesn’t sag or settle over time, a side effect that fiberglass insulation suffers from when it’s installed incorrectly.
Is it worth it to spray foam attic?
That’s because open-cell spray foam can transmit air and moisture. Closed-cell spray foam is a better choice for keeping subfloor moisture at optimal levels, while open-cell spray foam is a better choice for walls and attics, because it allows homes to “breathe,” Yates said.
Which is better closed or open cell foam insulation?
Closed cell foam has a higher R-value than open cell foam, usually about 6.0 per inch. This higher rating makes closed cell foam better at keeping heat in or out of a structure. Open cell foams have an R-value of around 3.5 per inch.
