John's feeling a bit cold inside and he's not quite warming up to this salesperson's recommendations.
Replacing your Windows:
Below is a breakdown from the National Rating Fenestration Council explaining some of the common terms from the video. Every window you purchase should have the Energy Star Label sticker with the climate zone and energy performance rating.
We also included a video of Casey where he discusses air tightness and different types of styles, glazing and material. It's always important to consider the house as a system when replacing windows.
In the video skit there was no external shading on the south wall and it's a cold climate so generally a higher SHGC (Solar Heat Gain Coefficient) would be ideal. However, to avoid high cooling costs in the summer a .20 SHGC was recommended by the salesperson. Condensation on the interior of a window is not necessarily a sign of a broken window seal or bad window, you may have an issues with high humidity and/or lack of ventilation. That being said, better windows will be able to handle higher (and healthier) humidity levels in a home before having condensation issues.
