Spray foam insulation in existing construction--yea or nay?

As a way of remediating our ongoing ice dam/roof leak/no bathroom ceiling woes, we're looking at getting spray foam insulation in the roof. I know a lot of people love it, but my contractor (who is not my spray foam guy) hates it--and thinks its a good way to get your roof to rot. What's the straight dope? [more inside]

Insulating a double bricked house

Is it a bad idea to fill the air gap in between double brick walls? Our 100 year old house is in need of some insulation so we had a couple of companies give us a quote. One company recommended spraying Air Krete (a kind of foam insulation) in the gap between our double brick walls. The other company said this was a horrible idea and could damage our house! They said to rip out the plaster & lathe and install interior insulation. [more inside]

Financial Assistance for Adding New Siding With Insulation.

I posted a question last year about safely scraping peeling lead paint from my house and repainting. Pros estimate $25-30K (yikes!). One reply suggested that "It cheaper to just get rid of the old wood siding and just install some new one. If you do that, you might want to look into adding insulation; there could be programs that would provide some financial assistance." Does anyone have a suggestion as to how to find such a program? FWIW I'm in Westchester county in NY state.

Animals wear fur on the outside because they have to, why do humans?

Having an outer barrier to wind and a trapped air space inside is the best way to insulate. It's axiomatic for insulating buildings. Impermeable skin on the outside and fur on the inside seems more effecient than fur on the outside. It seems to me that you could wear a less effective insulator, turned inside out as it were, that would weigh less. Why don't people that use animal skins for insulation do this?

How can we better insulate our garage to keep the heat inside our house?

This surface is hot, hot, hot.

This thread on the blue inspired me to purchase a toaster oven, and I have it now, and it is amazing. But I have a relatively small apartment kitchen. I would like to be able to store stuff on top of it, and the top gets molten hot, especially when I'm doing pizza at 450F. What can I put on top of it, as cheaply as possible, to provide heat insulation and a solid surface? It's approximately 18" x 24". [more inside]

How would you frame / insulate these portholes.

I currently live on and am restoring an old dutch barge. I started with no idea what I'm doing and am slowly working my way up to lvl 1 boat restorer. The current job is insulating. I need to cover up all bare metal with insulation (I am using expanded phenolic foam board) but I also need to make sure I have sufficient wooden framing to attach walls to (it will be tongue and groove). The problem I am currently having is to the neatest way to insulate around some portholes and also insulate and neatly frame the triangular metal ribs. I'd like to leave the nice shiny brass visible but have everything else covered up neatly. [more inside]

Glass Block or Insulated Replacement Window

So I have been working on my house and making it energy efficient. It is now time to replace the basement windows in my split level. One double wide window needs to be replaced with one that opens to meet code, but the other three single wide windows do not. Would I be better installing glass blocks in those three, not vented, or installing either a picture, slider, or another type of insulated vinyl replacement window? If I should do a replacement window, which type should I use? [more inside]

How to cool this HOT house???

Just replaced a 50-year-old tar/gravel roof with white shingles. This is in Florida. But now the house is hothothot, heat keeps rising, air-conditioner runs constantly but can't keep up! It's just after noon and 84 degrees in here! The roof is low-hip, the attic is a crawl space insulated to about R-30, there's a turbine on the roof and three passive vents. Still hot! Depressing after writing such a big check. Capable roofer says previous thick layer of tar/gravel probably insulated a lot. But now what's my next step? 1. Would a white latex coating be more cost-effective than a solar-powered vent? 2. Any other suggestions? Whew, and thanks!

OK to insulate windows with regular plastic sheeting?

Will black plastic sheeting insulate my windows as well as the commercial shrink-wrap stuff? I've used window insulator kits like this and they work great. I was wondering if I could skimp. First, would any plastic do as well? I already use this stuff to block light while I sleep. If that's not as good, is there something special about shrinking the commercial kit plastic with a hair dryer, or is that just for looks? I'd rather not borrow one every year.

Should we go from suck to blow?

We just had an energy audit done for our 104 year old house and 3/4 of the heat loss was coming from the uninsulated walls. I was advised to get cellulose insulation. I've heard bad things about blowing insulation into old houses like mine, but the auditor said it would be densely packed and not be a problem. I've been reading up and haven't been able to find any definitive answers. Is it okay to have cellulose insulation blown in to my old house if it is densely packed?

high performance gloves while maintaining dexterity

What's the cutting edge in gloves that allow for high levels of dexterity in extreme conditions (e.g. north pole). A colleague and I have been thinking up creative ways to allow high levels of dexterity while keeping the insulation factor high. Say you're a worker that has to work outdoors in extreme conditions for periods of up to an hour, yet you need to be able to work with hand tools, press buttons, etc. Is there an industry standard for this sort of thing? Anyone have any info on state of the art (or near future) technology in this area?
