Door for sealed room

[Robin_of_Loxxy]

What is the easiest way to install a door for a room that you build in a room? The room is also going to be a sealed room. Is standard cheap prehung door the way to go and just build around it? What about sealing under the door, is there a common method?

If your building a sealed room within a room,why frame in a door at all?Frame the rest of the room just like normal,and when you deciede where your entrance will be, leave those studs a little wider apart.After all your wall framing and ceiling framing is done,and your ready to seal your room with poly or what ever your gonna use,go get a zipper door and theres your door.

I used a pre-hung exterior door from Home Depot. It has a foam seal that is both light and air tight.

METAL door with magnet laced weatherstripping on the frame. Caulk/seal where the door knob seats on the door then you just have to deal with the threshold. I would not use a conventional threshold but something that rises above the bottom of the door so the door can butt against and there is were I would use some conventional weatherstripping. You'll also find a few holes in the magnetic weatherstripping on the corners and a touch of caulk works well.

Something like that...

The zipper door sounds good if that will work for you. I prefer a solid door though.

Build a wall and leave an opening for the pre-hung door. The door will tell you what the opening should be. Install door. You may need some foam around the door if you didnt hang it good. Then use a sweep at the bottom. You can use the zippered door as well for a better seal.

This same idea is of a concern for me as well. I'll be framing a 10'x7'x7' room, and need to have a 2 door system to prevent light leakage, and other things.

I was thinking about buying a 24"x80" pre-hung door from the home depot. Install that, and seal as best as I can. Then on the other side of the door have a zipper door. I want to be able to have a "change" room where I put on a clean suite and walk into my actual grow space. See attached image for an example.



Robin, maybe this will give you an idea?

We have a winner!!!!

Spend a couple dollars more on an exterior door and your sealing problems are taken care of at the factory.

a roll of foam(tape) always works as well, if you didnt want to get the exterior door.

No it doesn't work as well, or even close to as well. Hang a few hundred doors and you'll see what I mean.

it's always worked fine for me(the trick is getting the door tight enough), but then again I havnt hung a few hundred doors and you are right from the factory you dont have to mess with getting the door right. go with what works!!

The first time one hangs a door the tendency is to try to get it tight - a "perfect fit" kinda thing. Once the door is painted and won't close because the fit ain't so perfect anymore - the paint has made the door bigger and the opening smaller - one realizes that space is not their enemy. The problem with roll foam is that it sucks in general. Nevertheless, when used, it requires some space and can't just be squished to nothing.

I dunno - I make some big cabs using regular doors that I custom cut to fit the opening. Even with the proper tools and skills it's a pita to mount the doors and get them lightproof. Popping a pre-fabbed unit into the opening would be sooo much easier. Just wham, bam, on to bigger and better things with no fucking around and no problems. And if a person is building a sealed room the extra $100 for a better door should be a minor budget item.

I'm all for DIY but you have to draw the line somewhere; otherwise you're going to find yourself standing at a forge pounding out your own hinges.

After sectioning off my rooms with poly & drywall i decided to go with a product i seen online. You can pretty much order the walls in custom lengths and cut them down to fit perfectly. They work off poles and clips and i use a reflective material to make the physical wall. I cut in zipper doors wherever i need one and its simple to remove and reinstall.I love my curtain wall.
Might be worth a look for some of you guys.

I was too cheap to get a pre-made door and frame, so I made my own. Probably not gonna do that again.

But the walk-in fridge/freezer style is the way to go.

I also bought an exterior insulated door for my sealed room. I had a tough time finding a left hand/open out door though. Most are right hand/open in. Open in doors take away from usable space so thats a no no

The trick I used to get the door hung perfectly was to allow more room then needed, take the board to be used as the king stud and a board cut to length for the jack stud then pop them together on the floor for both sides. With them nailed/screwed together i butted them up to the bottom of the door as tight as a frogs ass and temporarily screwed them there. Then I tapped the tops until the gap around the door was perfect and the door opened like it was on ball bearings. Temporarily screwed them in at the top. Cut the top plate of the door to length and put that in place then the cripple studs above that. Permanently screwed it all together and I had a perfect fit with no shims or any of that BS. The door fits so tight in the studs that you couldn't even move the frame if you tried. Fixed the door to the studs with scews and all was done. Less then an hour and 4 beers to finish the job

Here are some pics... still a work in progress....

Open out doors work great too if you have neg pressure in your room... helps hold the door shut for a tighter seal IMO.
