Extra Attic Insulation. Can I add polystyrene panels over existing fibreglass batts?

I have access to 6in thick polystyrene panels which I would prefer to re-use rather than take to the garbage dump. Can I lay them over existing fibreglass batts to increase the insulation in the attic ? The house is 4 yrs old so is up to code and is located in Ontario, Canada where the winters are cold. I'm worried about causing a moisture problem.

Attic insulation-should I insulate floor to ceiling?

I am in Conn. and the person helping me has said the roof needs to breath. This is a 4th story on a 3 family house. It is A shaped. I plan on covering the insulation after to finish the space off for storage. I think this will keep the 3rd floor warmer. The floor is insulated, but I wanted to do the wall which makeup the pitch of the roof. I have never heard of the roof needing to breathe before. Is this true or can I go ahead and insulate everything?

Refrigerator Insulation?

Background: I was looking at Costco and they have their big semi-rugged totes on sale this time of year for like $6! The thing I'm pondering is sticking one in inside another and filling the space between with insulation.  But what to put in between? You're probably thinking what I'm thinking, Pinky:  Spray it full of Great Stuff foam. But then I'm looking at my fridge going... that thing is literally freezing inside and not even cool to the touch on the outside!  What kind of insulation do they use?  I'm guessing something trickier than Great Stuff, what with Energy Star ratings and all.  In short:  What is it and where can I get some!??

what is the best material to insulate your walls with? does styrofoam work well for keeping your house warm?

I have thick brick outside walls that will freeze in winter. I want to cover them with wood and some insulation material from the inside, hoping some of the heat from my oven will stay in the house. I can imagine styrofoam would work -which would be nice because it's cheap-, but i've never tried it. glasswool is too nasty, I'd rather not get into that. does anyone have experience with this?

DIY Home Insulation

So I know I need to better insulate my attic for the coming winter but, money is tight and the to-do list is growing so I began thinking of alternative or DIY materials to do the job. I know Cellulose insulation is shredded newsprint treated with chemicals to make it mold and creature resistant, and on a small scale maybe that process could be a fun experiment, but not for 1000 sq ft. My next thought (and current favorite) is to acquire styrofoam packing material (box inserts, packing peanuts, un-used food and drink containers) and mill them up to about the in to some uniform size. Then get some cheap plastic bag/ tube material and fill strips with a couple of inches of styrofoam. Then the blanket o’ foam could just be laid out over the existing insulation in the attic. Now, before I start this endeavor I thought I would check with the instuctable think tank to figure out: A) any better ideas 2) what R rating a 3 inch loose fill blanket of styrofoam and plastic would have III) Is this a terrible idea due to moisture being trapped under the plastic Also in a previous forum someone suggested re-routing their dryer vent to the attic and I was wondering if anyone had tried that and/or anyone’s thoughts on that. -Odo

Need help with DIY cooler insulation

Long time fan, first time poster. I'm looking to convert a cool-looking vintage toolbox into a heavy duty lunchbox. I'm currently prepping the metal for paint and looking into what I can use to insulate the box. I've thought of: * spray foam insulation: Good coverage and thermal protection, but not water-resistant enough (think condensation) * fiberglass insulation (pink stuff): Good, but unsure about how cold it will keep things * styrofoam: probably the one inch sheets used for basement walls below grade. Best solution so far. Before I do something that will likely mean stripping the box clean and starting over, I thought it best to see what others might have to say about this. Any and all help is greatly appreciated!

insulating radiator cover

I'm looking for suggesting for upping the r-value on top of my radiator. Every window in my apartment has a radiator underneath it. I'd like to have some plants by those windows ('cause y'know, they need light and all) but I'm concerned about heat from below drying & killing the plants. A couple of the radiators have covers, but they're metal, so no insulation there. Ceramic pots may provide some insulation, but I'd really like to lay down a layer of some kind of building insulation proper just to be safe. The question is, what kind? Batting won't work, and the foam insulation panels I've seen at the hardware store I know are a fire hazard... plus not too fond of plastic-type materials. My dad suggested something he called "thermal block" which I believe is aerated concrete panels, but which I can't find a source to purchase. I'd like to spend less than $20, preferably less than $10 on this. Please help!

How to insulate a cooler box

I have just bought a plastic cooler box. It is two boxes in one: an inside lining, an air cavity, the outside case and  of course a lid and handle.. I would like to improve the insulation. I have a 750ml can of expanding polyurethane foam which I thought of spraying into the cavity. It will dry in an hour. I can work out the exact volume  to be filled with  the foam by prefilling it with water and measuring the amount of water that pours out of the cavity , but I do not know the best way to apply the foam. Any ideas, please. For example should I wrap the inner box in anything before pushing it into the wet foam that I  spray against the inside of the outer case? Robin

These windows I have are too new, to replace. There are small recesses on the exterior of the wood window frames where I want to insert permanent glass/plexiglass cover for insulation. I need advice on what framing I can use, similar to a poster frame trim where I can install it around the glass, then slide it into the window recess. I’d like to use an aluminum trim that is fairly narrow that would look good. I find framing trim that has slots I can slide the glass into, but what I’m finding is too thick.

Could one insulate their attic and/or walls with those stupid plastic grocery bags...safely and effectively, that is?

I have switched to some awesome reusable bags I bought at Office Depot that have a little bag that clips onto your purse or belt-loop. But I joke to the grocery clerks (when they look at me funny when I hand them the bags and say no more plastic) that if I bring home 1 more plastic bag I'm going to drill a hole in my wall and start stuffing them in for insulation...my question is...Could I Do That? Safely first of all, but also effectively? This would be a HUGE find if it is...We could hit a planetary Royal Flush...Reducing our energy consumption by cheaply over-insulating our homes (an option that would make it possible for poor folk to take advantage too) AND getting those pesky bags off our streets, out of our oceans thereby reducing pollution and halting the devastating effects they have had on the sea life, AND reduce the space they take up in our landfills, PLUS with this as an alternative to having to turning them in, the current backlog of "recycled" bags piling up because this economic down slide reduces the amount of these goods that China is importing to turn into future landfill occupants. So can it be done?

Help reducing energy bills in rented house?

Hello! I have lived in the same house for the past two years, and in the winter our energy bills get ridiculous. It is an old house, the main part being built in 1902. We plan on doing the bubble-wrap window insulation on every window in the house and adding some weather stripping, wearing layers ourselves, and I plan on getting an electric blanket in my room to turn on just before I go to bed, and turn off once the bed is heated up. (My room is the only room on the 2nd floor and gets very cold. The previous tenant of this room used a space heater, but I think they are pretty inefficient.) Are there any other cheap ways to lower heating costs? They guy that owns our house is really stingy, and I highly doubt any requests for better insulation or a newer thermostat will be answered. Thanks in advance!

Using quickrete to sound proof walls?

After reading online I thought about an easy cheap alternative to lessen the noise in my garage studio room from escaping to the outside world.  After the new construction the smaller space seems to echo much more than before, thus the need for more soundproofing/deadening.  I though about building forms with plywood backing and filling them with readymix quickrete with wire mesh on top.  After fastening the frames onto the brakets I have that will be firmly fastened to the wall in staggered pattern drywall and carpet padding will be applied on top of the plywood side of the form that would be facing toward the middle of the room thus creating a second relatively thick layer of sound deadening with roughly 1 1/2 inched of dead air space trapped between the outer and inner layer walls.  Has anyone ever tried this?   Thoughts, comments, suggestions welcome.  To clarify:  From outside to inside I would have:  Siding - Standard Wrap and OSB - Stud- Moisture Barrier- Insulation - 5/8 Drywall - 1 1/2 inches of dead air space - Wire mesh side of concrete forms 1 in thick - concrete- plywood backing side of form - carpet padding - drywall - carpet   Thanks.  John

Retractable white roof for passive heating /cooling ?? Dual season roofing idea? Answered

Last summer my top floor apartment was over 115 degrees indoors with blinds closed !  In a recent email to my landlord to report a broken mailbox I suggested the possibility of painting the apartment buildings roof white .  In reward for reporting the mailbox he says I could paint the roof but only above my apartment  . Cool . He says that the insulation was not adequate when built . The apartment has also gotten down to 30' in winter so I can only guess how cold it would get in here without the current black roof.               QUESTION ;  Are there any ideas to help solve both seasonal issues ?   I can't re-insulate because I rent .  I was thinking of a retractable white cover for hot summer days that can be removed in autumn . Or maybe even a white paint that would insulate against cold ??   An original idea was something like Bubble foil but I doubt that would stand up to weather.  Any suggestion would be great .
