- When you turn on your heating, you want it to stay inside your home. Powering up the heating causes the heat to rise directly up into your attic. It’s then up to your attic insulation to do its job and block the heat from escaping.
Poor attic insulation is problematic for your home and your bank account. So, it’s obvious that you need to invest your time and money into insulating your home, but what attic insulators are out there for you to choose from? Which attic insulation is best? And what are the potential risks of each of them?
This article will outline the 4 types of attic insulation you can pick from, plus dive into the pros and cons of each. By the time you’ve finished reading this article, you’ll be able to make an educated decision that best suits your property, budget, and priorities.

Would it be a good idea to have both insulation installed in the attic?
You could. But I would recommend 8.5” of Open Cell Spray Foam on the roof line instead.
you would not need to do both because you be changing the dew point of where the hot air and cold air would meet. you need one or the other. I would not recommend doing both.
Shiny reflective stuff towards the heat or facing away from it?
During the summer when it's 90 degrees outside my attic is 120 degrees. Would the radiant insulation reduce that temperature fluctuation and by how much?
Probably not.
@@ncvman yes it would. the heat would be trapped in between roof sheating and insulation. there should be a vent channel there to ridge vent to let heat escape.
One thing that I always wondered was if that radiant insulation would do premature damage/aging to my roofs wood and shingles.
based on the graphic, the cooling / heating of the joists and roof shouldn't be affected. this assumes the venting is at the soffit (overhang/ behind gutters) and ridge (peak)
A RADIANT BARRIER IS NOT INSULATION & HAS AN R-VALUE OF ZERO!!!!
it can do damage if there is no gap. the gap allows for hot air to escape, and in the winter it will allow for ventilation so that condensation does not build up.
Thanks, I needed to know how many inches of insulation I need. I would have like to see how the radiant barrier is installed.
keep in mind that number changes a bit, I think I was recommended 16 to 24inches.
for the radiant barrier, looks like its just stapled onto the rafters. just be sure the airflow from the soffit to the ridge vent isn't blocked
They should just make shingles the prevent heat from coming in your home.
you would think they would have done this by now. we still have so far to go with home technology huh
Not possible because the tar-backed shingle's main job is water-proofing.
What about housed with baffles? Where should the reflective sheet go, under the baffles sandwiched between them and the roof or stapled on to the frame of the house, covering the baffles?
Onto the framing. Radiant barriers need to have air on at least one side to work correctly. You would install the barrier on the framing so that there is a layer of air trapped between the barrier and the roof itself. The barrier has to be tightly sealed against the framing to prevent leakage. This causes the air in the small gap to get very hot and rise to a vent at the peak, as cooler air enters through the soffits to replace it. The rest of the attic is cool because the heat is reflected away from the air in the center.
@@mannys9130 gotcha, that makes sense, thanks for your reply
❤❤❤
You are a sparkys nightmare
Would that cook the living shit out of shingles and cause the sealant to fail prematurely?
I have done this. Doesn't do jack lol
When they do a home inspection, they report whether you have attic insulation or not could be a price point issue😅
I was wondering if it was just another thing to increase price I have a single layer of shingles with the old black sheeting underneath and I’m having a metal roof installed over that I think I’ll be ok

Insulation doesn’t prevent heat/cold from going into your living space it slows down the process of heat/cold transfer to your living space depending on the R-value (inches). Stick to plumbing buddy..
Thanks man. 👊
@@SonofDaVinci4 when
Unless you use spray foam. Spray Foam is air impermeable.
@@marcosvalles6995OP is still right though. thermal energy can travel through liquid or solid easier than it can through air. its just the state change from one to the next that makes it much more effective
