Rob is the president of Carmel…

When windows aren't the culprit of a leaky building, solve the mystery with an energy audit.

Liz Vogel replaced the windows and updated the heating system in her small multifamily building in the Logan Square neighborhood of Chicago. But she still noticed that parts of her home were not staying warm in winter. So she set out to solve the mystery of the missing heat. She saw icicles hanging from her roof, and that was a clue that pointed to where heat was escaping. The presence of these “ice dams” meant that Liz was paying to heat her roof and melt the snow instead of heating her…

Should this Duct Layout be Banned?

When is it ok to put your ducts into an attic, tight up against the Roof Deck?  With more conventional building techniques, I would have to argue: NEVER!  I do not care how the homeonwer pleads to keep their storage space, you cannot count on delivering cool air to the conditioned space with said branch duct.  Even if you did figure out a way to secure the duct to the peak without crushing the inside diameter, the CFM is not the problem.  The real issue becomes the dry bulb temperature of…
