I'm looking at two manufacturers of uPVC windows. They use different frame profiles that are nearly identical, the colored foils are from the same supplier, the spacers and glass are slightly different but overall the specs are nearly identical. The price quotes are very close but structured differently so it's difficult to compare apples to apples. The biggest difference is their approach for higher alltitude installations. One uses a pressure release tube that is pinched at the final destination and only the units requireing it are tempered SG.

Hello:

I have emailed the GBA contact twice and I have called several times to no avail. I will not leave a call back number, so they must pick up the dang phone when it rings. We used to do that in all the offices I ever worked in, but not anymore I know. However, they could at least answer my email. All I am trying to do is order a subscription. I tried using the website and it does not work for me.

A major source of heat loss/gain are the side east and west facing plaster & lathe side walls.

I've measured the temperature of those walls; they stay hotter than outside temps well into the night, and there's 5-10 degree increase as you go up the wall from floor to ceiling. They're actually hotter than ceiling and kneewalls alot of the time. There's also some moisture coming through; the plaster is rotted through under the window apron and there are cracks in the corners.

Hello, I really appreciate this website.

I understand that powered attic ventilators have a lot of problems. But my contractor is suggesting adding one to support a whole-house fan, due to the limited attic ventilation. (I do have some passive ventilation but not quite enough, and the gables are maxed out because it's a flat roof.)

So as long as I always run both fans at the same time, and as long as the cfm of the whole house fan exceeds the cfm of the attic fan, is there still going to be a problem?

Thanks!

(Examples of what I am referring to can be seen at: http://vastern.co.uk/wp-content/uploads/2013/03/Splayed-cladding-detail.jpg AND http://www.bartonqualitytimber.co.uk/images/categories/chestnut%20claddi... )

I am not terribly conceded about the cedar: if it is stained all 6 sides with two coats and placed on black painted strapping, then it should handle the elements reasonably well. My main concern is what the substrate behind it should be.

I had R60 blown into my 1000sqft attic where there was previously only about R11. Baffles were installed in almost every roof rafter. Air sealing of attic floor was performed. This is a low pitch asphalt shingled hip roof over the whole house.

We had our basement encapsulated in the fall last year and made it through winter no issues. They used a thick mil high quality (apparently) vapor barrier and then sprayed /fogged with mold preventative. I don't think there is any more mold - smell is not musty really and I don't get a mold allergy reaction.

As a long time visitor and few years member, I have tried to absorb the lessons, opinions, science and conjecture presented here. However, I now find myself confronted with conflicting theory regarding unvented roof profiles.

For my own project, (high altitude, dry, -10 to 90 F) I have regarded the "top" layer of sheathing in an unvented assembly to be essentially in dead space - not exchanging air or moisture - the underside in contact or glued to impermeable insulation, the top side sealed off from all contact with the locally required ice and water shield over the entire roof.
