I have a Masonite Brand Mahogany door with big oval glass in the middle. The top right corner is slighlty warped. I have full sun hitting the door from noon on. In the summer the door is straight. But in the winter it warps the top right corner allowing a draft. Does anyone think a storm door to seal off the draft will help with the warping issue also?....here's a pic of the door. I think the previous owner got it from Homedepot..Thx in advance for the help..
