Most South Central Pennsylvania homeowners know and understand the importance of attic insulation. But fewer are aware of attic encapsulation, which is similar to attic insulation but can offer unique benefits for your York, Harrisburg, or Carlisle home.
Today we’re going to explain what attic encapsulation is and how you can use it to upgrade your home.
1. What Is Attic Encapsulation?
If you’ve heard of encapsulation services for your home before, it’s most likely crawlspace encapsulation, where insulation, air sealing, and plastic vapor barrier installation is used to turn your crawlspace into a semi-conditioned part of your home, helping you better regulate temperature and moisture.
Attic encapsulation, which would result in a sealed attic or an unvented attic, is similar. Regular attic insulation is installed on the floor of your attic, which creates a thermal barrier between your attic and the rest of your house. Attic encapsulation involves installing insulation on the attic rafters—the underside of your roof—instead of your attic floor. This turns your entire attic space into a semi-conditioned part of your home.
Attic Encapsulation: The Pros and Cons
Since attic encapsulation is different from attic insulation, there are a few things to keep in mind when deciding whether this is the right home upgrade for you.
Advantages of Attic Encapsulation
Fewer attic mold or moisture issues, since your entire attic is sealed from the outside
Reduced HVAC energy waste (any ductwork or HVAC units installed in your attic are now in a semi-conditioned space)
It’s easier to use your attic for storage or as a bonus room, as attic temperatures will be more consistent year-round
Disadvantages of Attic Encapsulation
Since the surface area of your attic rafts is likely more than the attic floor, attic encapsulation costs can be higher
Some shingle manufacturer warranties may be voided if the attic isn’t ventilated
