Glass windows are not the best option to enclose your porch for the following reasons: Traditional windows are not built for spaces without climate control. They lack functionality to save the outdoor feel of a porch. And, they can be expensive and complex to install. Sunspace porch windows are made intentionally to hit the middle ground. Our customers are looking for something that is going to allow them to maintain that screened-in porch feel – like an outdoor room – and also give protection when they want to keep out the rain, snow, dust, and wind.
