How are they for Insulation against heat and cold?

I would not say that. You can stick them on any flat surface but they are very thin. You could insulate and cover your insulation (without having to worry about covering the lines in between sheet rock as long as it's mostly flattened out,) then apply, but they are mostly just decorative.

While they are styrofoam, the thickness is such that the insulation properties would be negligible.

That's a good question -I never thought of them in that way. I placed mine in a room above the garage; a room that is always cold. I walked in there this morning and it was still cold but I also do not have window treatments up which would help. I don't think they really made a difference either way. Hope this helps you.

If you had a drafty attic and you put these on your ceiling, they would help. A better solution would be to install more insulation in your attic.

I have never used them to keep something warm. I only use them to carry my water bottle around. Sorry!

I disagree with the previous answer: they are not very warm... they are somewhat warm. They dexterity is there but the intense grip of the rubber would make diminutive tasks difficult. I will be adding thin cotton glove liners to mine this year to provide a boost to insulation. Since I ride a bike with them, I don't have to worry about the added loss in dexterity. Theses gloves are not effective below 30F degrees.

I use them for pre- and post-season driving in my convertible. I've had no trouble with cold seeping in - including highway speeds in low 40 temps. Unsure if using them in true frigid weather would keep you warm enough - but then again, layering is always best.

Haven't had any issues using these for heating or cooling and I have 3 of them on the main level of my house. You should be fine using these on your vents in the winter unless they get really hot. If your vents get hot enough to melt plastic, you have other problems. :)

I think these are supposed to last a long time and our use is for outdoors with very cold and hot temperatures.

This is designed to be wrapped in insulation. Foil or paper-backed fiberglass or foam that can withstand the heat would be ok.

They are designed to keep you from being cut while wearing...I know of no claim about being heat resistant.

Sorry, but I haven't taken them out since there were installed so i have no idea what the insulation situation is right now. To be honest i never thought of it.

It should not be an issue. I am not sure what the cold rating is. It gets down to -20f here and they work fine.

NO! They are way too thin for that. They will help, and will keep the wind off, but anything cooler than 65 and you will be cold. You CAN use them as a layer. It takes a little work, but under my 3/2 they work fine.

I understand your concern in regards to getting hot, but I believe you should be fine with these. I ran a half marathon in these and never got over-heated.

My boyfriend and I have both tried them to below zero (Fahrenheit) temperatures. They work great under snowpants and take the edge off under jeans.

No they are not insulated, and you can always put a old blanket and that will work fine.

I didn't try hot things but for cold, you need to have an ice pack in the bag. The insulation lining is there but does not work totally on its own.

I wouldn't think these would give much protection on hot pavement. We had a dog who's paws required protection in all extremes oh heat, cold and wet conditions. We found Allweather Muttluks essential for him, in summer and polar fleece the best for cold conditions as long as it wasn't wet out. Thee polar fleece breaths more than the waterproof ones and have more padding but may be too warm for extreme heat. Expensive but they are very well made and last much longer than any others so you end up spending the same if not less over time

We have only used these for keeping things cold and they work great. We soak them in water and then freeze them. Not sure about heat but i would try putting them in boiling water but don't boil them.
