To vent or not to vent? That is the question. Spray foam experts will generally recommend to keep your attic sealed as much as possible; however, there is a concern of moisture and hot air collecting in the attic during warm/hot months – especially in Texas.
Technically speaking, here is a reason why not venting your attic won’t make such a big deal:
Because the thermal boundary is now the underside of the roof, the attic should only get about 10 degrees warmer than the inside of your home. If you properly manage the amount of moisture that may enter your home through crawl spaces, vents, cracks and walls, you shouldn’t have a problem. To go a step further, installing a heat pump water heater can help mitigate moisture within the attic. This will also help reduce temperature and lower utility bills.
The beauty of open or closed-cell spray foam is that it gives you control over your home’s temperature, humidity, and air quality. It’s important to insulate your attic with proper material in order to maintain a regulated home.
