We are putting a 2" wide rolled steel curved header in a 2x6 wall. Our thinking is that we need to position this header as close to the inside as possible with as much ISO foam to the outside as possible to prevent condensation on the steel. We've decided to use 2-1/2" of ISO which only gets us R16.25 if my math is correct. This allows us to put 3/4" of wood on the inside of the steel so we have something to fasten interior trim to. There is 1/2" Zipwall exterior sheathing. There is no exterior foam sheathing.

I was talking to a contractor in my area about my siding options and I asked him if when re-siding my house I could add an inch of foam board insulation under the siding. My walls can get pretty cold in the winter months, after all.

He told me that it would be a BAD move and that my house would rot from the inside out due to condensation and moisture building up.

The room is located under a covered porch that is enclosed on three sides. Do I need to leave any room for air movement? Should I have a vapor barrier toward the living area even though it is a ceiling?

I was thinking of using a vapor barrier installed backwards between the sheet rock and the insulation. Good Idea or bad idea?

My four story 1880's row house has no insulation between floors. I am unable to drop ceilings or build up floors and I don't need total sound-proofing, but I would like to reduce noise as much as possible by drilling holes in the ceilings and packing insulation between floors. (Thermal savings is just an added plus)
Every contractor recommends a different product -- Green Fiber Cellulose, Insul Safe, air krete, etc. How can I compare these apples and oranges? What should I specify in the bid to the contractor? How much less sound transmission (noise reduction) can I get?

We have a client in a Zone 5 climate. His house does not have any south-facing fenestrations to take advantage of passive solar energy.

He is proposing to remove a gable-end chimney and fireplace, which occupies a good portion of the south facing gable wall, and replace it with low U, high solar heat gain glass to superheat his house interior, hoping the thermal mass of the drywall interior will be enough to store the heat energy his family would need at night. His design includes superinsulated polyiso interior shutters to cover the windows at night.

I am building a modern home and planning to use weathered cosmetic beams to add a touch of rustic. I have found some old beams that I am going to use in the kitchen (very expensive) and I want to age the rough sawn to match the weathered beams.

I have read that the grey aging color can be achieved by using vinegar soaked with steel wool, with eco wood treatment, with India ink with Isopropyl rubbing alcohol, even show polish with wax and paint, along with numerous other methods.

We are building a new home and we want to use stamped concrete for ALL the flooring throughout the home. We also want to use concrete for ALL the interior walls so we can use stamping on the walls as well.

We will not be using any drywall in the entire home. If possible we would love to build our entire home without any vertical wood walls. I would appreciate any advice, thoughts, or questions you may have. You may contact me via our email @ hoody2@clear.net or you can call me 708-257-9801 and discuss any part of this process you may have experience or knowledge in.

I have purchased a house in Vermont and it needs new siding. This is the perfect opportunity to add more insulation!

The current wall construction from the inside to out is: 1/2" gypsum, 4 or maybe 6 mil poly, 2x4 with R-11 fiberglass batts 16" OC, 1/2" plywood sheathing, some sort of building wrap, and vertical wood siding.
