Q:Roof insulation- how does it work? How is the heat circulation changed?
Well insulation makes a dead air space (air is stagnant). Since the air is not moving the transfer of hot and cold is slowed down considerably. But since you have to create cross ventilation to reduce rotting in wood and the build up of explosive gasses. Its a crap shoot that it even does any good. Radiation is heat so that's covered by the dead air space. Convection is usually not an issue with the cross venting. Also for conduction the insulation should slow it down considerably.
Q:Want to use fiberglass insulation in big closets under home roof?
If there is no existing insulation you need a vapor barrier 1st or you need "faced" fiberglass, the one with either plastic or brown paper on it. I put it as thick as you can afford.
Q:if you had snow and all the snow is off your roof and the house nex store has snow do we need insulation?
That is very observant of you. Yes this could indicate that you are losing more heat than normal through your roof. Though, you do want to be careful in the placement of any new insulation, you will want to avoid any vents that are there for ventilation of heat and moisture in the summer and any recessed lighting fixtures as to not cause an overheating problem with them. This is a good investment and it will pay you back in heating and cooling cost for years to come.
Q:We are putting a tin roof cap. Do we put some sort of insulation/stripping under the tin roof cap?
I'm assuming your talking about a ridge cap normally you would seal it in with tar or polyurethane caulk and put your shingles over it
Q:the roof of my mouth hurts bad.i worked all day with sawdust and insulation yesterday.is this the problem.?
The okorder.com, and see if I could find out anything there, if not I'd see my doctor. Insulation can get into your lungs and nasal passages and do a great deal of damage. That's why you should always wear a mask when woking with it. I would'nt worry too much about the sawdust.
Q:Is it worth to insulate the roof with styrofoam (thermocole)?
if u mean roof as just below the shingles this is not recommended as it will cause the shingles to become very hot and prematurely fail,,the best way to lower the heat in an attic is ventilation,,if u have an attic its best to insulate the floor of the attic and lots of ventilation
Q:Can you use Great Stuff foam as insulation under a metal roof?
I don't think Great Stuff foam insulation is meant to be applied in the manner in which you need. It is used to fill gaps and cracks, not be sprayed out in thin coats. whenever I've used it in the past, I found out it did not like to be spread out, or "worked".
Q:can i use a maximum 4" RIGID insulation to obtain an r-33 value on a commercial roof?
the R values, i am not sure. that white stuff is NOT Styrofoam. it is a cheap imitation. Real Styrofoam is made by DuPont, is usually a light blue, with a plastic seal coat on both sides. that thin plastic seal coat doubles the R value. what really does the insulation, is trapped air. air is actually a poor conductor of heat. the foam is actually little bubbles of air. dead air that is, air that cannot circulate and move. it works similarly to the way a down vest or coat works, it fluffs up and holds the air pockets out within a confining structure, thus retaining heat. the rigid stuff will last much longer, i can tell you that much. the white foam stuff deteriorates quickly. buy cheap, get cheap, is the general rule. you may wind up only having to do it again in a few years.
Q:Is mineral wool any good for under roof insulation?
Yes, be sure to leave an air space between the top of the insulation and the roof deck to allow for ventilation, and use a vapor barrier on the interior side of the insulation.
Q:Is it good to get cavity wall / roof insulation in the summer?
Insulation helps both in heating in the winter and with cooling in the summer!
