Insulate ceiling openings

A simple, inexpensive insulation box placed over attic stairs, ceiling access entries and whole-house fan installations will save energy consumption. Most of these areas are under insulated or not insulated at all. It is equivalent to leaving a window open all year.
Building an insulation box is a simple do-it-yourself type project that will pay for itself quickly. Make a box with 4-by-8 rigid insulation board, duct tape and batt insulation on the inside of the box. Tape all joints inside and out for strength. Place the finished box three inches over the edge of the opening it covers on all sides.
