Gable and ridge vents literature


Should I install a ridge vent with gable vents and without any soffit or other eave venting? The attic space is currently vented with a gable vent on each end (no fans or other active). The house is a gambrel-style / barn-style / dutch colonial so there is also unvented roofing shingles around the 2nd floor. The two areas (steep shingles around 2nd floor and gradual above attic) are not connected, save any framing gaps between the two.

Extremely humid interior atmosphere

We are currently working on a project in the Chicagoland area at a water reclamation district. We are re-roofing a building that enclosed the water filtration pools with extremely high levels of humidity.

We are installing a new roof membrane over the concrete topping slab on the roof and running vertical on the multi-wythe brick walls that serve as both parapets as well as extend up to a higher level than the adjacent roof. The roof membrane will be attached to an exterior grade plywood that is attached to the brick.

USA New Wall & Swedish platform framing


I recently came across Greg La Vardera’s website

Although I have read much on energy efficient wall types here, I haven’t noticed any comments on the USA New Wall. I am interested in other peoples opinion on this construction and how it compares to other energy efficient wall types. (I am thinking about the Building Science Corp s list of walls and how they score relative to each other - )

Damp beam in the middle of the house

Hi, I've got an old house (probably in excess of 200 years) through the middle there is a beam sitting on a couple of courses of bricks. I've noticed that the bottom of the beam is wet and starting to crumble (although it could have been like this a very long time) The wooden floor was replaced with concrete about 35 years ago. I am assuming that the water is coming up through capillary action. I was wondering if there was a substance to stop the rot and seal the beam?
Many Thanks

Flashing finless (European) aluminum-clad windows

I have finless, wood-frame, aluminum-clad windows to flash, and have attached a detail of what I'm planning so far. I'm looking to address water that makes it behind the aluminum cladding and comes down along the outside of the wooden frame, at the bottom of the window. I want to move it outside of the wall assembly rather than leaving it to run down behind the clapboards.

How to install EPS around window area w/ recessed windows?

Anyone have a detail or written explanation on how to wrap EPS around a recessed or innie window buck area? The window will be sitting 5+ inches away from the exterior ICF wall. Stucco cannot be applied to the area without some EPS but how does one bring EPS into that recessed area and how do you attach it to the wood or concrete buck?

In zone 4 (Northern VA), what is the best way to keep pipes from freezing in a 2x4 gypsum sheathed wall with aluminum siding?

Picture attached but the vent pipe will be cut out and adjusted to run to the other stud cavity and a 2x6 will be added above the copper to brace a pedestal. There is 2 3/8 inches between copper and exterior gypsum and a little over 1 inch between the pvc and exterior wall. Rain does not hit this wall because it is the house side of a semi-enclosed porch so it has another wall roughly 4 feet in front of it and it has a living space above the porch so it is not open to rain from above.

Cellulose insulation & vapor barriers?

Several insulation contractors have recommended loose fill cellulose attic insulation for my 1970's era ranch in northeastern CT. The house is heated with oil via a hydronic baseboard system. Central AC was installed 12 years ago, with equip. located in the attic. There have been no problems with the AC to date. Here is my question:

Inground Gutter


I am finishing my basement and came across this article on inground gutters on Fine Homebuilding's site which Martin Holladay had contributed (and it is a new concept to me, but seems exactly what I need):

The description shows 6-mil plastic or better 1 foot below grade and attached to the basement wall with pressure treated furring and Tapcon screws. (See photo IngroundGutter.jpg)
