Use Your Porch Year-Round: How to Insulate a 3 Season Porch
Here in North Carolina, our winters are fairly mild most years, so we can use our outdoor living spaces longer. A 3-season porch is, as the name implies, best for use during three seasons (spring, summer, and fall). However, we have a few tips to help you use your porch during winter as well. Here’s how to insulate a 3-season porch so you can use it even as the temperature drops.
Permanent Insulation for 3-Season Porches
First and foremost, when you build your 3-season porch, you can (and should) use insulating techniques when building the walls, roof, and even floors. This permanent insulation will go a long way in keeping your porch warmer during the winter.
Not all insulation is created equally, however. There are a few types of insulation you can consider:
- Spray Foam – This product is durable and mold-resistant. It also does an excellent job at insulating, since it expands to fill in cracks and crevices. You can use it for walls, roofs, and floors, but it is best for use during the building process when the walls are open, rather than after the fact with an already-built porch.
- Blow-In – With blow-in insulation, you can add insulation easily either during the building process or after the fact. The product is a fire-resistant, treated cellulose material, which not only adds temperature insulation but also sound-proofing.
- Rolls/Batts – During the building process, you can also have rolls or batts of insulation installed. This is typically made from fiberglass, but can also be other materials such as mineral wool.
- Vapor Barrier – You wouldn’t use a vapor barrier on its own. This is a plastic barrier you install over other insulation to prevent moisture, which can cause rot and other problems. Basically, it makes your insulation more effective over time.
You can read about these and other types of insulation here. Which is right for your home? It depends on your specific porch. We can make recommendations based on your home and budget.
Temporary Insulating Methods for Porches
Although insulation for 3-season porches starts during the building process, the windows/screens mean that permanent insulation can only do so much. You can also use temporary insulation methods for porches during the winter. Here are a few options:
- Add a thick outdoor rug. This will help prevent heat loss through the floor, and you can remove the rug during the summertime if you prefer.
- Use insulating curtains and shutters over the screens. This will block your view of course, but it will give you a usable room during the winter.
- Purchase draft stoppers. When Structurally Speaking builds an enclosed porch, we make sure the doors and windows seal tightly. If you have an older enclosed porch, though, you may find that your porch is drafty especially during the winter. Some inexpensive draft stoppers can make a world of difference.
You can also use a few more permanent but inexpensive methods for insulation, such as weather stripping around older windows or replacing single-pane windows with double- or triple-pane windows. Structurally Speaking can help you with small porch renovation projects. Give us a call any time for a free consultation.
Even More Tips to Make Your 3-Season Porch Usable During the Winter
3-season porch insulation can help keep your porch warmer during the winter, but that’s just the start. Here are some other tips for turning your screened-in porch into a space you can use all year long:
- Add a space heater or electric fireplace. While enclosed porches typically do not have built-in heating or air conditioning like the rest of your home, small portable heaters can make a world of difference when temperatures plummet.
- Make sure your fan is rotating the right way. During the summer, you want to draw hot air up and out, but the opposite is true during the winter. Did you know that the direction of your ceiling fan matters? In the winter, set your fan to rotate clockwise to make sure warm air is redistributing around the room.
- Add cushions and blankets to outdoor furniture to create a cozy sitting area. We recommend keeping them inside your main home where they can be nice and warm. Carry them outside anytime you want to use your porch.
