What is the Safest Method for Insulating an Attic?
The attic is a home space you may avoid out of fear.
You have legitimate excuses.
You’ve watched too many scary movies. You’re allergic to dust. You don’t need to see another spider in your lifetime.
However, it’s time to let a different fear rule your life: FOMO, the fear of missing out, of course.
That’s because if you avoid improving your attic with insulation you’re missing out on some serious benefits.
So what’s the safest method for insulating an attic, and what benefits can be seen?
The answer: an unvented attic equipped with Icynene Classic Max spray foam.
The basic process involves spraying the underside of the roof with the open cell foam, which has a built in ignition barrier.
Insulating and air sealing an unvented attic with Icynene Classic Max spray foam has several benefits.
First, there’s the safety component. Fires in unvented attic assemblies with Icynene Classic Max smolder in less than a minute, according to the company.
“No other spray foam insulation product has been as extensively tested as Icynene Classic Max™. Unvented attics insulated with Icynene Classic Max™ spray foam have a distinct advantage over traditionally-insulated vented attics when exposed to fire. It is this advantage that will help protect homeowners from being devastated by a runaway attic fire,” Icynene VP Engineering, Paul Duffy said in a release.
Another advantage to insulating an attic is safe storage.
Some well-intentioned homeowners store belongings in a vented attic. However, this strategy invites disaster since a vented attic permits plenty of moisture.
If you give your attic some TLC, most notably in the form of spray foam insulation, you can cancel your storage unit locker and park both your cars in the garage. Yeah, that’s what a two-car garage is for.
“The attic will stay dry, avoiding problems with mold and wood rot, and thus can serve as living or storage space,” the U.S. Department of Energy writes.
Finally, insulating your attic with Icynene Classic Max spray foam is an effective air seal for energy savings.
“An unvented attic is conditioned space and won’t be subject to the extremes of temperature common to vented attics,” the International Association of Certified Home Inspectors reports. “Heat is thus less likely to escape into an unvented attic from HVAC equipment, and if it does, it will remain within the conditioned space.”
