DIY – Sealing the Attic Hatch

DIY Sealing the Attic Hatch – Attic hatches are often not air sealed, allowing air to transfer between the conditioned space and the attic. In addition, they are usually constructed from thin wood or drywall, neither of which provides any appreciable resistance to energy loss. These issues results in drafts, heat loss in the winter and heat gain in the summer. Fortunately, you can easily air seal and insulate your attic hatch, saving you energy and money. Other Resources.
