How to Insulate Interior Doors Used For Attic Access

My builder installed interior solid wood panel doors for access to "walk-in" attic closets. The air in these attic closets is not conditioned.

At the time, my builder compromised with me and installed pretty decent weather stripping on these doors... so they're not drafty. But, on very cold days the doors feel cold to the touch.

My thought is to attach a solid piece of 2" high density styrofoam insulation to these doors.

Any other suggestions?

That sounds like your best bet, the only other solution would be to buy/build insulated doors for the openings.

Be advised that the edge along the knob side will probably have to be beveled for the door to open and close. It will be easier to do that before you glue it to the door.

Thanks for the reply guys...

I've been meaning to insulate these doors for several years and I am finally getting around to it. I was going to back the insulation board with strips of 1/4" plywood and screw through both into the doors.

The bed rooms with these attic doors stay cold in the winter and hot in the summer... if this doesn't work, I guess I will be looking at better quality doors.

depending on how the door is hinged, and how wide the jamb is, I've nailed a 1/2 x 3/4 "stop" onto the cold side of the jamb so that when the door is opened, a piece of foam can be pushed tightly against this stop. The tighter it fits the opening, the better. A couple pieces of rope serve as a handle, when placed through holes drilled in the foam. (knots on the back side through a wooden reinforcement if needed)

this usually results in a tighter seal than trying to attach the foam to the door.

Here are a couple of links on insulating and air sealing which will point out other important areas that contribute to the cold up there. In reality, it is colder up there than you think, because the heat rising should make it warmer.

Good reading in any case. The Vermont link is slow to open but worth the wait.
