The halls were packed with an enthusiastic crowd, and you could tell that the business of construction was back in a big way. The first place we hit was the Passive House Zone where a strong contingency of European companies are showcasing products that meet the super demanding needs of Passive House certification.
Doors and windows are large reasons why our homes consume much more energy than they need to. One of the latest and most interesting window companies to enter the US is Internorm. The company offers not only certified windows, but also doors and integrated solar powered window blinds. They have a slick triple pane glazing system where the glass comes right to the edge of the frame, much like a flat screen TV. Their doors are probably more efficient than your home’s wall.
Imagine a glass-based product that is not only highly insulative, but can support the weight of a building. Foamglas makes a R3.4 insulation board which can isolate the dreaded thermal bridge in places where no other product can be used. It’s a bit pricey and has been available for years, but using it where you need it makes for a real money saver—especially over the life of a building.
