"Should we do a 3 season or a 4 season room?" It's the first thing almost everyone asks us about a sunroom, so we wrote up the full answer.
Here's the quick take: it's the same Royal room either way. Framed into your house, on a real foundation, with Pella or ProVia windows. The 4 season version just adds heating and ventilation so you can use it all year.
The new guide also covers small sunroom ideas, screened porch vs glass, ceiling and floor options, and what really drives the cost. If you've been daydreaming about a Carolina room off the kitchen, give it a read.
