"Lots of interesting ideas. Typically in the North East we would have just skinned stone on a masonry wall. You could mortar the joints. Obviously you could seal it an close it. I would seal it with open cell spray foam, Keep the…"
"Maybe Zone Pressure Diagnostics could of been done to determine where the significant air leak spots are. If dry stacked, air leakage could be more significant in walls than in attic.
During the audit, I wonder if the walls felt very…"
"Air sealing a wall like this must be done with a vapor diffusive material or you will get spalled stone faces from sealing materials holding water. I recommend mixing hydrated lime with local clay soils, this is the way they have been sealed for…"
I have the same problem after the catastrophic result from Blower door test 30-35 ACH@50Pa of two stone built houses in mountain. I and my team developed air sealing technology for stone walls without mortar.
After the air sealing we…"
"I had a similar issue with an exposed historic brick wall in a condo I was testing. We couldn't find the leak with our eyes or thermal imaging becuase the leak was EVERYWHERE. We confirmed this when we taped a sheet of poly over the wall and…"
"It looks to me like the main leakage is from the intersection of stone and conventional framing, not necessarily directly through the wall.
In the second picture, is the stone i see that appears to be interior…"
"Thanks everyone for your input. The test was a two blower door test (that only got up to -43 Pa) - we had to add up both manometer readings and use the Can't Reach Fifty factor. The wall is a facade about 3" thick that is made to look like…"
"Are you saying that there's not a block or poured concrete wall in the middle of all that stone? That's almost inconceivable to me on modern construction, but I suppose it's possible... in which case you would have to grout the entire…"
Is it possible to cover the wall adequately enough to isolate that air leakage? Even if you covered the wall exterior and interior with plastic sheeting, or covered the exterior, and built a plastic wall on the interior, you might be able…"
"Hello. I have a large basalt stone floor to vaulted ceiling tall fireplace that also leaks. I have reduced my ACH to 8 from 12 and am now working on the fireplace. My plan is to caulk/foam (may be more economical) the whole dang thing…"
"While that is a lot of leakage, is it all coming from that wall surface alone? Wall leakage is a big issue, but what if you concentrated on all the other leaks could you bring the exchanges down enough to warrant not having to do this…"
"Dry stacked or is there mortar holding it together? If there are actual mortar joints you can see about getting a mason in there to fix all the B-holes - if it is dry stack then they will not like the fix (and no it does not involve mortar or…"

Real estate professionals who understand the basics of solar and know how to market the benefits of an installation will have a market edge. For most real estate agents and appraisers, assessing the value of solar is a new…
Energy Upgrade California offers rebates up to $6,500.00 in SDGE territory. Up to $4,500 in other territories. Unfortunately they don't/won't promote it. I can't get straight candid answers from the contractors supporting the program. Only…
