insulation

How are insulation and ventilation dealt with in a loft conversion?
Q. When a loft has not been converted, you are supposed to put insulation on the floor of the loft. There also has to be ventilation under the eaves to prevent condensation. But when a loft has been converted to an extra room, what should be done about insulation and ventilation? I suppose you would remove the insulation on the loft floor, because you no longer want to prevent heat entering the loft, so would you insulate the sloping roof itself? And you would not want a breeze flowing through the loft, so would you cut down on the ventilation?

A. The sloping timbers on a roof are called rafters, a lot of the time they are 100mm from edge to edge but when converting a loft building control say that we have to put 90mm foil backed insulation between the rafters while still maintaining a 40mm gap for airflow, additional timbers are fixed to the under side of the rafters to obtain the extra 30mm or so needed to fulfil their requirements. Having done that they say that we then need to fix 30mm foilbacked insulation covering the complete underside of the rafters before fixing the plasterboard to eliminate any coldness that would normally occur if the plasterboard was in direct contact with the rafter, this is refered to as a "Cold bridge" As for the insulation in the floor, there is… [cont.]

what type of insulation should I use to insulate under my kitchen floor?
Q. I live in Portland, OR, so it gets chilly in the winter. My kitchen was added to the house in 1993, and there's a crawlspace below it. During the winter, the kitchen is cold, and the floor is uncomfortable to bare feet, so the obvious solution is insulation. Should I use ordinary Kraft R-13? How does it attach, do I just shove it up between the joists and staple it into the bottom of the floor? Or does it attach to the joists?

A. Paul's right on the regular fiberglass. Remember that the paper side always is on the side of the living space, so in this case, the paper will be "up". So, it makes stapling a little trickier. You can also put it up with steel rod insulation supports. They come in boxes of 100 usually, and are cheap. They are slightly longer than the space between joists, and you just push them into place, and their sharp ends bite into the wood enough to hold up the insulation. Meausure your joist spacing to make sure you get the correct length rods -- you can't relay on standard.

About fiberglass or insulation, how do you remove from your clothes?
Q. I'm trying to pin point why my allergies are so bad, and my husband has been working at removing insulation from this old building, he comes home and it seems like that is when I really start getting bad conjestion. I've tryed washing all the things he touches or comes in contact with. how do i clean this up or find out if this is what is causing my allergies? we have fans on to keep it cool in house and I was fine early this morning but the second he walked into our office i started with the conjestion. anyone ever have this or know about this. I've even gone to the doctors several times and they just prescribe and prescribe, nothing is working. thank you.
