Does anyone have any thoughts on how to make a pocket door act as an exterior door in the winter? Outbuilding is divided in half between a screened-in porch and a closed-in guest room. Pocket door serves as go-between. Would like to be able to keep the closed-in part warm in the winter.

This is an unusual application for a pocket door. Pockets do not normally have any weather stripping or insulation. Unless you build an insulated wall on one side, or fit 3/4 inch foam on the inner wall during construction, I can't think of any way to insulate this kind of door. You might be able to improve thermal performance with weather stripping around the opening and a flexible sweep along the bottom.

Considered a thermal pane slider, french door or conventional swing door to replace it? One of these options should fit in the same rough opening and would be more thermally suitable.

I have a suggestion to soundproof your pocket doors that would serve a two fold purpose. There is a very good insulating as well as soundproofing material that could be adhered to the inner or outer surface of the pocket doors. It is a material called Mass Loaded Vinyl (MLV) for short. It is a black vinyl material that would be adhered to the face of the doors on either side (it makes no difference) and it would act as a thermal barrier as well as a soundproofing barrier. It is only 1/8" thick so it should not inhibit the doors operation in any way. However, it is a very heavy material and would need to be adhered to the pocket doors with an industrial strength contact cement, (something like 3M-77 or 3M-80) I would suggest that you remove the pocket doors in order to adhere the vinyl to them.

Once the doors are back in their runners you can paint them with a vinyl or latex paint to match the decor of the room.

Kathleen, you can find this and many other soundproofing and insulating products at

I hope this helps you Kathleen.

Should I use a solid core or hollow-core door? It seems like a solid door would transmit sound more easily.

No, the solid core door will be better. Mass is what's needed to reduce transmission of sound. The heavier the door, the better. The next issue is gaps. That's what I'm looking to figure out. My pocket door runs across the strips of an engineered wood floor. I'm looking for something I can glue or nail to the bottom of the door to deal with that gap.

Not sure if this diy project was done - but a drop down door sweep is what we are using on a pocket door to an elevator in our home.
Check out this link:
We also used a solid core door but I wish I had insulated the inner part of the pocket with the foam too! We are also about to add more weatherstripping around the top side of the door that slides into the pocket as well.
Maybe something like this:
or something like this attached just behind the door frame but still pressing on the door itself even when it is 'closed' (completely out of the pocket - but part of the door is still 'inside the pocket)
Adding it on both sides and also considering slipping a hairlike strip inside the door frame further back to stay pressed against the door on either side as it slides in and out of the wall pocket.
Like this strip that is actually made for an exterior glass door - hoping it will work for us:

Hope this helps someone else looking to insulate a pocket door! And now I'm thinking more and more about that foam insulation. I just might be doing more than pulling the door out of the pocket in the next few weeks - with the cold weather upon us!

You need to build a bigger wall...
