What type of door from finished to unfinished area?

4080 Views 7 Replies 5 Participants Last post by  ScottS
I'm getting ready to install doors in the basement and I'm trying to figure out what kind of doors to get for between finished and unfinished areas. Do I use interior doors with no weather seal, or do I use exterior doors? For instance, I have a door from my main rec room into my water heater closet. The water heater closet is 3 walls of concrete and the front wall where the door would go has (looking out from inside) insulation -> studs -> drywall -> rec room.

Hopefully that all made sense

Is your water heater electric or gas? If gas, you may need to make sure there is enough air exchange.
haha just after I posted I began to think... "man I'm shouldn't have said water heater.. I'm going to get all sorts of questions now"
Let's pretend the hot water heater isn't in there

If the unfinished space is heated, you can use an interior door. If it is unheated, you would need either a solid wood interior door, a solid wood with a masonite cover door or an exterior door. All with weather seals.
Scott, if you mean heated as in a duct ran to it, that would be a no... the only heat to the rooms are from equipment in them or heat from other rooms entering from the door opening.

I too used interior doors into my three unfinished areas. Unless you have significant drafts coming through that area you should be fine.

By conditioned space, I mean with the same HVAC service, exterior insulation, etc. as the other spaces you are finishing.

For example, my mechanical room qualifies as conditioned so I could use a regular door, but my shop space isn't so I needed a more substantial door. This is needed for two reasons: fire stop and to stop movement of conditioned air into a "cold" space.

The cheapest solution is often a masonite covered solid door. These are made with this use in mind and have air seals, but aren't true exterior doors. I picked one up from a lumber yard in my area for $29 at their "scratch-n-dent" sale in the fall. It had scuffs on it, but other than one nick, was in perfect condition once painted.
