Q:how to minimize the itching from exposure to roof insulation?
I'm not sure if your questioning what to do before or after. A lot of experience contractors that work with insulation use generous amounts of baby powder on their skin before covering up prior to work. The baby powder fills up the pores keeping the insulation out. Insulation can travel through cotton clothing, but it is better than nothing. After the work is done wash off with cold water. The cold water closes the pores in your skin, while rinsing off the bulk of the insulation on your skin. Then use any temperature you like to complete the process.
Q:Without loft insulation ,the roof space is full of air.Why does this not keep the heat in?
Because air can circulate, (it's called convection) and transfer a lot of heat. In other words, air alone is a very poor insulator. .
Q:My roof is a spray on white foam/insulation. What is the correct name for this type of roof?
Most typically, it's a sprayed polyurethane foam system. Simple repairs can be made with a sealant, unless you need a section replaced.
Q:do we need insulation if we have a roof tile?
Oh yeah. You need insulation. Think of it this way. If you turned a stove top burner on medium-low and placed one of those roof tiles on it, it would be too hot to pick up. If you put down a small piece of insulation first, you'd be able to pick up the tile with no problem.
Q:Interior roof insulation.?
Why would you want to waste money heating the attic? There are several reasons to put the insulation directly above the living space. Increases the life of your roof, prevents ice damming, saves money, helps avoid moisture issues in the attic and roof sheathing. Is that enough?
Q:Can I insulate my aluminum patio roof?
I agree with RustyNail that the panels are thin and not meant to support that kind of weight. But, I think a wall anchor that spreads the weight inside the foam would work if that's the only place to attach. I'm imagining that there's no wall available since these usually are just supported at the ends. If so, then my first suggestion would be no curtains at all. My second would be to find a long wall anchor. With 6" of foam, I would think you could do a 4" long anchor and get pretty good support. Rusty may disagree.
Q:why do icesicles form on the edge of my roof in the winter when my insulation value in my attic is at the...?
"R" I think stands for "Resistance" factor against heat loss. It resists the heat transfer but doesn't stop it. There is no such thing as perfect insulation. Snow itself is a rather good insulator. So even though you are only losing very little heat, the snow on top of the snow directly on the roof helps trap that heat at the bottom. So the first layer will melt.
Q:How much insulation is required in a house roof in new York ?
323 square feet per cubic mile.
Q:Which is better for a 2-story house : radiant barrier roof or more attic insulation?
the best is more attic isolation so that the heat don't come directly to second floor.
Q:Best roofing insulation against radiant heat (sun)...pls help.?
Expanded polystyrene (EPS) comes in sheets and is very long lasting and safe to use - no fibers, no itchy skin, no breathing issues....this is also used to keep cold out as well as heat and is durable.
