Abstract: An access door for insertion into an opening in a construction surface is provided. The access door has a frame for engagement with edges of the opening in the construction surface. The frame has a channel formed therein for receiving a thermally insulative material to provide a thermal break between the frame and the construction surface. A door is operatively coupled to the frame and movable between an open position allowing access through the opening in the construction surface and a closed position preventing access through the opening in the construction surface.
