Q. I need to put more insulation in my attic. It is finished for storage and has a wood floor. Where do I insulate? Do I just lay it on the floor for the winter and put my boxes on top? Do I need to do something special along the edges? What kind should I use and is there a tip for installing? Thanks!
A. If there is no insulation under the flooring (plywood or OSB usually used, you'll have to pry up the floor and place the insulation between the joists. Installing between the joists like I described is merely rolling it out and stuffing it in. Nothing special needed. Typical R-Value for an attic is R-38, but R-values of the insulation will depend on your area of the country. Check out this site for your areas specs:

How can I contend with the heat in an attic room during the summer?
Q. ...I am a renter, my room being upstairs. There are 3 knee doors to the attic space around the room. The attic is not insulated and has one slatted opening at one end of the space.
I am pondering on a cheap and easy fix for the unbearable heat that will ensue this summer. Should I maybe insulate just the knee doors? Someone recommended a dehumidifier, but moisture isn't the problem. And if I were to get a high-powered attic fan or two, it might be a little pricey on the electric bill...

A. If you leave the door to your attic room open and place just a regular fan in an attic window(facing out) you will replace the hot air in the attic with cooler air from below in no time at all.
How is the ventillation in the normal attic?
Q. If there is a gas leak in the attic or some air pollution in the attic, how does the attic vetillate it? In a normal house, the attic ventillation is good enough to circulate air quickly?
I don't have a gas leak. But if there is possibly a gas leak in the attic where gas furnaces are located, do I need to worry about it?
How strong is the attic ventillation? Sometimes, I feel the negative air pressue when I open the door that leads to the attic.

A. A gas leak in any enclosed space is dangerous. You should be able to tell pretty easily how ventilated the attic is. If the house is old, and has not been reroofed recently, it is likely not to have ridge vents, or soffit vents and may not have much ventilation.
Even with ventilation, you don't want a gas leak in the attic. "Pollution" on the other hand will likely be drawn outside instead of into the living quarters, as you indicated in your question (air is drawn out of living quarters into attic). The attic has a chimney effect, drawing air out of a house.
The specific answer to this question of how quickly it is ventilated has a lot to do with age and style of the house, and where it is located. It is also pretty common that people shove insulation over soffit vents, reducing the ventilation.
