Condensation on windows with steel SIP home

We built a steel SIP house this summer near Hannibal, MO. We've been very happy with the results with one exception. The builders used steel L-angle to wrap the windows on the outside in order to better square the openings before installing the windows. They also installed the windows. This steel angle is not thermally broken at all. One part of the angle lays against the steel panel skin on the outside, and the other angle extends past the window into the living area about 2".
We do not have siding on the home. We have left the exterior steel exposed.

Advice needed: Recycled XPS rigid foam

I've located 4x8 sheets of 3" recycled foam board. This is DOW blue board, claiming to be 3" thick.

Should I nab this up for exterior insulation around the foundation? The price seems right and I love to recycle.

I am working on an indoor pool building

I am working on an indoor pool building. We installed an Armstrong W-H 1100 ceiling system. They did not want us to use the felt lining in this system.

Now the client wants the ceiling panels lined. I need to find a black material to line these panels with that I can use over an indoor pool.

Is there an under-sink recirc pump model that has an ECM motor and can be operated on demand?

I'm looking for a recirc pump model that has an ECM motor and can be installed in a house without a dedicated return line and can be operated on demand. The best option I've found so far is the Bell & Gossett ecocirc wireless (, but I don't really need/want the wireless part or the batteries. Hard wired is fine/preferable.

Do you have new windows? CEMAC needs your help

Did you recently replace the windows in your home? If so, you can help advance research that could reduce the cost of replacement windows.

The Clean Energy Manufacturing Analysis Center at the National Renewable Energy Laboratory is studying the costs of installing energy-efficient windows in homes—from the cost of the windows themselves to costs for installation and labor— and we’re collecting as much data as possible. We are searching for copies of actual invoices from energy-efficient window installations.

Tilt turn windows with good visible transmittance

Can anyone recommend manufacturers of quality, energy efficient, tilt turn windows with good visible transmittance. If I'm going to put a hole in my wall for a window, I don't want to fill it with a thick frame and dim glass. The NFRC website lists 64 manufacturers of tilt-turn windows, and I don't know where to start. I'm designing for zone 5. I am cost sensitive, but willing to pay for quality.

Do the "channels" in the Insofast product reduce the efficiency of this choice for exterior insulation?

I really like the idea of one product for insulation/ capillary break and insofast seems to remedy this. BUT as the other articles have indicated, those wiring channels and even the vertical channels are a concern. Has anyone done any research into this? A guy would hate to talk this product up to a client and then realize that we are going through a lot of work for a product that doesn't meet expectations.
