Is blow-in insulation good for use between an attic floor and a second floor ceiling? If so what precautions?

Q. should be taken? There is no heating in the attic, but two chimney pass thru the entire house and attic to the roof. Are they a danger of fire or smoke or smoldering of the insulation? And the manufacturer warns of light fixtures recessed in the ceilings of the room below. How can one know without tearing up the entire attic floor where those fixtures exactly are?

A. Cellulose insulation does not settle. Blown Fiberglass does. Cellulose is also extremely fire-retardant and the bugs don't like it.

The main concern regarding the light fixtures, in as far as cellulose insulation, is that they can overheat and fail to function.

Your best course of action would be to remove the flooring in the attic. If you choose to replace it, be sure to fur out the ceiling joists so that you don't compact the insulation (whichever you decide to go with) and lose R-value.

My house was built in Los Angeles in 1906. I wish to to convert the attic to a bedroom?
Q. the attic to a bedroom with a bathroom including a shower and tub.. What changes to the foundation.and ceiling will I be required to make to satisfy the building codes and mitigate problems if there is an earthquake.

A. You need to find out if the house is a qualified Historical structure or property. If it is, I would not recommend you doing the remodel if you are on a tight schedule. If you have the time or it's not considered Preservation worthy, then you can proceed. Since the house already have an attic, the only thing that you really have to concern yourself with are the floor structure, shouldn't be a problem since the house will be conventionally framed. Electrical, Mechanical and Plumbing will be huge, since you have to replace everything. Insulation and window exiting clearances needs to be considered as well.

How can I insulate my rented attic bedroom?
Q. I rent, and my bedroom is a large attic conversion. It's very energy inefficientâI can feel heat loss through the ceiling even on a cool summer night. How can I make it more energy efficient without making structural changes that will require my landlord's cooperation? I plan to put weatherstrip around the windows and I'm considering caulking the joists, but the only other thing I can think of is tacking blankets up on the walls and ceilingâa fire hazard, and not very elegant.

A. Hi, check out encapsulated insulation batts, it's insulation that is in a plastic type blanket. If you have knee walls and attic access, just staple it between the joists. When you move you might take it with you too! Another solution might be blue board, its a foam board that you could put up and tape seams making it tight, but it may have to be trimed just for that space and it's best to leave it. If your landlord pays any utitlity you might say you get the material I'll put it in. B
