Holding back cellulose

I'm just about done air sealing our attic and getting ready to blow in cellulose. For a few sections I need to make a vertical "wall" of it. One part is where the stairs are. As discussed in another thread part is a flat ceiling, then a vertical slope down to the stair ceiling. I'm going to put fiberglass batts on the vertical sections, but want to blow in cellulose on the flat part. I'm thinking of stapling window screening to the top plate of the actual wall and then staple it to the ridge beam of the house.

What building monitoring OS and display technology would you recommend for an office building in Oakland?

We are a nonprofit office who recently installed a solar array on our building's flat roof with GRID Alternatives, and want to raise awareness for staff and visitors of the benefits even though they can't see the system working. By instilling a sense of pride in our system, we hope to encourage staff and visitors to track and be more aware of their behavior (plug load usage, water, etc) and how it ties in with the building's performance.

Alpen Windows

We are planning a new home in Southeastern, Pa. We are located in climate zone 4. I have requested quotes from Bieber, Zola and have found the price too expensive for the budget. I have also received a quote from Alpen Windows. The price is slightly more than half of those that I mentioned. I realize there are major differences and tradeoffs. Does anyone have experience with Alpen Wiindows?

Paradigm Windows

Who's used them and what do you think of them? None of the references I found here were from people actually using them, curious what the drawbacks are. Aside from vinyl isn't for everyone.

Recommended taping of plywood and foam layers

I am building a small casita (500 sq. ft.) in Northern California in a mild climate with hot summers. My wall framing is 2x4 w/ 3/8 continuous plywood shear (also insulated w/ R-13 fiberglass batt insul.), which I will cover with two layers of 1/1/2" Polyiso (Firestone) insulation (has fiberglass reinforced face). I will cover everything with Tyvek housewrap and fasten 1x4 battens creating a rainscreen, and attach lath and plaster as an exterior finish to the battens.

The builder wants to glue engineered wood flooring onto a new concrete floor, over a primer. Is this wise?

Any good entry doors out there yet?


We're almost done with our Minneapolis energy retrofit, but I still haven't come up with any good entry and side door options. The home is framed with 2x4" walls, and there is also limited side to side clearance to add a more substantial European frame.

Gable vents vs. wind-driven snow: Is there a brand of gable vent known for preventing fine wind-driven snow intrusion?

Another fine snow/strong wind event here in eastern Canada today. After pretty much every storm like this I tend to find piles of snow in clients' attics, right around the gable end vents on the windward side of the attic (naturally). In one particular case it seemed to be a pretty big factor in the amount of moisture in the attic, as there was serious frost covering most of the roof deck. These gable vents always seem to have the louvers and screens that are meant to prevent rain and snow intrusion, but they fail in this regard when faced with very fine snow being blown sideways.

Roxul Comfort Board vs. Thermafiber RainBarrier

Any differences I should be aware of before I choose? I am wanting to use mineral wool for exterior insulation on a wood frame, two-story dwelling. Very impressed with Roxul online information, technical specs etc. Can't find much about RainBarrier, other than the company info sheet, but it's 1/2 the price of the Roxul. Thermafiber says that the Rainbarrier HD is the product they have made to be comparable to Comfort Board, but cannot find any comparisons between the two.
