Low-E Glazing and Energy Efficient Windows

While waiting for the mason to create the openings for the windows we have been looking at our glazing options.  We've been talking with Craven Glass Company on Trent Road about supplying our windows and we've decided on an aluminum storefront system with some operable windows.  Our building gets so much direct sunlight we've decided to go with a low-E coating on our thermally insulated glazing with an thermally broken aluminum casing.

You can get glazing with high or low solar gain low-E coating (how much heat comes through from the sun). Since we'll be more worried about heat from the sun making the building too hot in the summer, we're choosing a low solar gain low-E coating.

The windows will be thermally broken (which means there is a rubber gasket in the metal casing around the window so heat or cold isn't directly transmitted from the outside to the inside) and reduces the chance of condensation forming on the windows.


And, we're making some of the windows operable so when we have a mild day (hasn't been recently!) we can open the windows for some air. I hope we get some of that weather soon!
