I purchased a Champion four season, over $35, 000 sunroom a copuple of years ago. I immediatley had bugs entering the screens. Bees and Wasp infiltrated my home. I have lived in the home over 15 years and the only time bees have entered is when I have the a screened window open on the sunroom.
There claim to enjoy the comforts of indoors with the pleasure of being outdoors is false. The only time I can use the room is with either the heat or air on because there is no breeze because I cannot open the windows.
Champion says that bugs coming into a room of a screened room is a natural ocurring event.
Beware of fourseason sunrooms by Champion, they are a ripoff.
