What is it?
ComfortWall™ is NorthStar’s exclusive wall insulation system for new construction, both residential and commercial alike. If the inside of the walls is exposed, such as during an extensive remodel, ComfortWall can be used in existing construction projects as well. The system is designed to fill cavities completely, providing a custom fit with no gaps or voids, to maximize the building’s thermal properties (R-value).
That’s useful but, still…what is it?
ComfortWall is blown-in fiberglass insulation system that is only available to be installed by certified installers. It features higher R-values than most common insulation options (R-15 in 2×4 construction, R-24 in 2×6 construction) and includes an air sealing package, for the safest, most durable, high performing and cost-efficient solutions for your home envelope.
Wait, home envelope?
Yeah, it’s not our favorite term either, but the industry hasn’t come up with anything better. Anyway, your home envelope is the boundary between your (hopefully) nice, cozy conditioned living space and non-conditioned spaces, which can be the outside or certain areas in your home, like the garage or attic.
Got it. So how is it installed?
First, the penetrations (holes) in the thermal envelope are sealed with caulk or low expansion foam, depending on the size and accessibility of the hole. Often, the base plate is caulked as well, which can be a large source of air leakage, along with other air sealing options that are available. Then, our installers staple (or glue, in the case of steel studs), our ComfortWall netting over the cavities. After the netting is up, the cavities are filled to the appropriate density with fiberglass insulation. That’s it!
Next question – is it for walls only?
The ComfortWall system is designed for use where the insulation is surrounded on all 6 sides, so kneewalls, rim joists, cathedral ceilings and between floors are also good applications. Attics, on the other hand, are not.
Rim joists? Kneewalls?
Just let us come to your job site or bring your plans in and we can go over these things.
A few more questions first:
Does it settle?
No, not when properly installed.
As with all fiberglass insulation on the market today, there’s no formaldehyde nor or there any gasses that are released over time from chemicals in the material or any kind of curing process.
How fast can sheetrock go up?
The same afternoon. There’s no drying time needed.
What about sound?
What about it?
Does it help with sound control?
Yes, of course! Sound can be tricky to manage, especially as the source gets louder, but insulation and ComfortWall, by extension, will help between rooms or floors, by eliminating the air space and holes for the sound to travel through. There are other options and products that help as well and, if separating off your child’s drum room is that important, we’d be happy to help guide you to the best combination for your problem.
Thanks, but I was more concerned about the nearby freeway. Anyway, is it combustible?
Nope. Again, fiberglass comes recycled glass and sand, neither of which is known for its flammability. The air sealing materials have a fire resistance rating as well.
There’s nothing in the air sealing or the insulation that fosters mold growth. Mold is usually a symptom of other problems, anyway.
Good interview question! The only negative really is that it requires certified installers to put in, so it’s not for Do It Yourselfers. But luckily for you, we have certified installers that will get the job done quick!
What about a warranty?
The material has a one-year warranty from the manufacturer and the installation is warrantied for as long as you own the home.
I think that’s it – what’s next?
