How to prevent fiberglass insulation from slumping down if there is distance between the walls?
Q. I'm finishing my basement, and in a few places there is a gap between the walls that are being built and and the concrete basement wall. How to keep the fiberglass insulation from sliding down over time? If I staple it, what would I staple it to? If I need some electrical work done, is it done before or after I put in the insulation (the studs will be there, of course).

A. If you can reach it and the insulation you have has a kraft paper backing - they are designed with a 2" edge to staple to the studs. If you don't have studs to staple to or can't access them - then I have used packing tape to hold insulation in place - the 2" wide very stickly clear tape. I would recommend getting all the wiring in before you insulate - best of luck

How do I install fiberglass insulation around wiring in walls?
Q. I am installing fiberglass insulation in my kitchen walls. I have some wiring going through the studs. How do insulate with wires in the way? Do I go behind or in front of them or not at all? Help!
Asked by gidge980 - Tue Jul 21 11:18:52 2009 - - 4 Answers - 0 Comments
A. Engage the advice of a licensed electrician. (See the link for details). In short, insulation reduced heat transfer and cables get warm when they carry current. So insulation around a cable prevents air circulation and increases the heating effect. Repeated overheating damages the insulation and carries a risk of fire. Therefore, a cable inside thermal insulation is effectively de-rated and you need to limit the current to a safe level. This means picking the right amperage for the circuit breakers, and might mean replacing existing ones with lower value. Do not insulate around light switches, and especially in the roof, any halogen downlights. Check local regulations on this.

Fiberglass insulation...?
Q. What happens when you inhale it or get it in your eyes, nose, and mouth? For example someone isn't wearing a mask or goggles while removing and installing insulation. What are the harmful effects? What happens when the particals enter your body? Does your body reject them or absorb? Does it continue to irritate forever? Help.. I am concerned for myself and someone I know!! Thanks!

A. Fibreglass insulation is a major irritant and it says so on the packaging. It has been one of the major problems with lung damage in construction work and home renovations in the past. N95 masks are a little expensive but they are much cheaper than a lifetime of respiratory problems. The tiny particles get into the air, into the furnace system and into your lungs, nose, eyes, and skin. Once in the lung they get lodged there and can cause infections, inflammation etc. If you have been involved in a project and are having problems now you need to go and see a doctor. There is no way around it. If you are considering a project buy the mask. One is good for 10 to 12 hours, wear long sleeves and pants, and protect your eyes.

Should I keep fiberglass insulation on basement ceiling?
Q. Bought a house about a year ago, and the basement ceiling is stuffed with fiberglass insulation. It's warm in the basement, especially the room where the furnace is, but we hardly ever use it. I'm wondering if all that insulation is trapping the heat the furnace gives off while it runs, preventing it from rising upstairs? Would it be worth removing it myself or just let it all stay in the ceiling? If you recommend removal what's the best way to dispose of it? Thanks!

A. I recommend leaving it. The warmth you feel is coming from air leaks in the ducts and from the furnace itself. The insulation works as a sound deadener as well as an air infiltration barrier. I insulated my basement ceiling for the above reasons, and it worked out well for me. The air temp in the room above stays more uniform, and the furnace cycles on and off less often. At night, I keep the door to the furnace room open, so that little bit of extra warm air filters out.

Does fiberglass insulation lose its effectiveness from compression?
Q. I am thinking about insulating the hood of my car with fiberglass insulation sheets -- yes the same kind that most people use in their walls. To make it fit in the engine bay, I will need to compress it, and keep it in a compressed state. I have no worries about overheating, as I will have MANY gauges to check temps with. I am just concerned with the effectiveness of fiberglass insulation, in its compressed state. Any R-value changes would be really appreciated!

A. If you compress fibreglas insulation, it loses its effectiveness, because it depends upon the air trapped in the spaces among the fibers. I would estimate that if you compress it to half its thickness, it would lose half its insulating power, at least.

The only "danger" from fibreglas insulation is if you handle it without wearing protective clothing, especially gloves - the thin fibers of glass will irritate the skin.

Normally if you run big appliances later at night it will save you quite a bit of money and energy. I think the cheapest time to run big appliances is between 9pm and 6am.

However, it depends on the installer and the material both, and they sometimes don't blow enough in, or it can settle. On the other hand, bats are a factory-determined thickness, so you know what R value you're going to get.

A. There is normally some insulation in the "ceiling" of the crawl space. Heat moves from HOT to Cold, and the cool crawl space should be insulated from your kitchen. If your Kitchen floor is cold you may even want more. Or put carpet in you kitchen. (It is done.) Insulation is normally thickest (6 to 12 inches) above living space ceilings, next thickest (3 to 6 inches) in living space walls, and thinnest below floors (3 inches). Any home builder, home addition contractor, or serious handyman can add more insulation to your crawl space.

Q. When you do fiberglass in wooden studs you can use staples to hold it in place so it does not shift down over time. How is it done with steel studs? Staples don't work!

A homeowner wishes to insulate her attic with fiberglass insulation to conserve energy.?
Q. The insulation comes in 40-cm wide rolls that are cut to fit between the rafters in the attic. If the roof is 6 m from peak to eave and the attic space is 2 m high at the peak, how long does each of the pieces of insulation need to be? Round to the nearest tenth.

A. The insulation batts, or blown-in insulation are not applied between the sloped roof joists...they are applied to the attic side of the flat ceiling joists. Since the attic spaces are all ventillated and open to the ouside air temps it wouldn't do any good to insulate the underside of the sloped roof.

A. No. It's good for insulating the climate, but not the sound. To insulate sound, you need concrete or bricks.

A. any home center, 1 brand is as good as another. If it is the first layer of insulation, be sure to have a vapor barrier against the warm side. However, if you are adding to existing insulation, get the unfaced (no vapor barrier) stuff.
