Low-e glass on storm windows
We live in a 1920 farmhouse in climate zone 4 and we’re in the process of having our original double hung wood windows reworked – spring bronze and weather stripping added, new window weight ropes, etc. Next summer we plan to reside our house and in the process install new storm windows. Right now we have old triple tracks with broken parts and we’re looking up to upgrade to a product like Allied Windows.
My question is regarding Low E glass – the storm windows are available with Low E on the interior of the storms (second surface). I understand the benefits of Low E glass on new thermal windows, but will Low E glass be of much benefit on a storm window, particular in the winter when the space between the wood windows and storm windows is not completely sealed to the exterior? In the summer it would help reduce heat gain but then would we lose heat gain in the winter? Or would heat reflecting back in from the Low E make up for for the heat gain loss?
Also, on some of the existing storms we have condensation build-up on the interior of the storm glass. We’ve tried to seal up a couple of the interior wood windows but we’re still getting some condensation on the storms. Would Low E glass help because the glass would actually be warmer from reflecting the interior heat? Thanks for any input, we’re just trying to do this right first time.
