Where to buy high R value rigid foam insulation?
Comments (9)Something a lot of people are unaware of, box stores are home improvement centers glorified hardware stores ,not a supply house or lumber yard. You won't find a 2 x 12 x 20' at these places.There are six of these stores, all the same distance from my home,you would be surprised at the product diversity from store to store.

Comments (33)No bb, that is not what I have. I guess I'm still learning. I just remember that when they sold me the hot water heater and boiler, they said it was a "direct vent" type. that's why I reiterated that. I thought a DV was just an appliance which was vented forcefully (horizontally outside of the wall or otherwise) instead of with a chimney type instrument. Thank you for the clarification. My two forced air heating units are in the attic and it's unfinished with a gable vent near them. A lot of (cold) air gets in through the vent when they turn on. Maybe that would do the trick. It does seem that it should somehow get air INTO the living space though. I definately understand what you mean about the negative pressure. I'll have to look closely at my units to see if they are indeed direct vent and if they're even installed properly. The hot water heater has a 3 inch PVC pipe going straight out the side of the house, that's it. The boiler (not hooked up yet) is the same way, near the HWH in the basement in a closet with louvered doors. The two units in the attic have that ven like I described. I need some kind of house audit... but the pros I hired to do the original work should have mentioned all this. I'm just learning this now after reading here for a while. thanks again for all the replies. I'm learning a bit from this. One more thing, I can't stop talking here... lol If I have both vents, in and out, at the same location, would'nt the "out" air just come back "in" with that setup? It would seem like a circle exchange of some kind and you'd suck the "old/bad" air back in....See MoreHelp--R-38 or R-49 insulation in DC metro area renovationl?
Comments (12)There is not a place in Illinois that the Department of Energy, International Codes Council, nor any other serious energy policy body suggests should have anything less than an R38 in ceilings and at minimum an R49 in others. That Illinois has yet to adopt national standards only speaks of Illinois' lack of seriousness as far as energy conservation as well as building code standards goes, and Illinois should be seen for the exception it is rather than as any rule or canon by which to measure the rest of the US. That said, what kudzu9 said is essentially true: more energy can be lost through a windows than through ceilings... but the caveat is that you must still comply with the energy code established by your jurisdication or energy compliance "paths" allowed. What this means is that you are legally obligated to do certain things depending upon your jurisdiction and the path selected. DC area may require as little as R30 for ceilings and as much as R49. The ultimate and final authoritative answer will only come from your local building code enforecement office....not the builder and from anyone in Illinois. Energy Codes are adopted statewide and modified locally just as are building codes. So check yours for complianace paths and alternatives. GardenWeb/ThatHomeSite "zones" are completely irrelevant to the discussion....See MoreDoes brick color effect r-value/insulation of a home?
Comments (2)The color of exterior walls would nave no effect on R value but it would have a slight effect on heat gain from the sun and the color of the roof would have a far greater effect on heat gain....See Morejarvinen
