One of the most important decisions to make when choosing a porch over a deck is whether you want the porch to be a 3 season room or an all season room. It is not just just a lifestyle decision, but also a financial one. For the most part, a 3 season porch means a screening system for your walls. Something that is not going to fight back to the winter wind. All season (4 season) means infrared heaters and / or windows. This Potomac, MD homeowner wanted to add all season livable space to their home, and expand their outdoor entertainment space. The result was a 22 X 16 porch with Eze Breeze Windows and Infratech Heaters, as well as an Azek deck for grilling.
