My church [tiny, with even tinier budget] is getting ready to wall off
an area for a nursery. If we put in a door (of course we'll have a
door), the state says the door has to have a glass panel so people can
see in.

One of the ladies suggested using Dutch doors so the top half could be
left completely open. Nobody knows where to order a set of dutch doors,
much less with a window in the top half, and I suspect they are quite
expensive.

How hard would it be to cut a hollow-core door in two just above the
knob and repair the cut edges by gluing in wooden blocks? And what
about cutting a 20" square hole in the top half and framing in a
Plexiglass panel? Would the hinges already be in the right place if I
start with a pre-hung door? (I know I'd need to add a second pair of
hinges.) The door probably needs to be hung on all 4 hinges *before*
cutting it in half...

Thanks,
Bob

I was going to do just this (install a Dutch door) for someone recently.

Don't use a hollow-core door: use a solid door. No patching or filling
necessary. Leave at least 1/8" clearance between doors.

Yes, hang it by all 4 hinges first, then cut (duh!).

You may want to consider adding a shelf to the bottom half; usual way is
to reduce the height of the bottom door by the thickness of the shelf.
Add supports on both sides as needed.

What he said. I've done this, too. Solid door, cut, with another hinge
for the orphaned side, and you're good to go.

Make the shelf big with overhang on each side and support underneath, if
you like.
That way, if can be used for a sign in/out sheets and whatever else your
church uses or needs for checking in/out the kids.

Do the state rules say how or what height the window must be? With a bottom
door in place to start, adults can see in as needed so a window shouldn't be
needed there.

You can go with a full door and cut it in half if you think it might be
easier, but essentially you're fitting two doors into an existing space. I'd
install the bottom door first just to get an effective working partition in
there as soon as possible and then fit the upper door with window as needed.

Would inward-swing pass fire code? Another thought is that a small
child could be behind the door, out of sight, when someone enters from
outside; bang! Another thought would be plexi, rather than glass, and
the shelf on the inside. Shelf on the inside would keep little fingers
from reaching up at the wrong moment. Have to plan for all possible
events with small ones )

I just noticed that this was cross posted to alt.home.repair,
so it might be a bit daunting to weekend warrior.

But for most woodworking guys, even a moderately skilled
hobbyist, this isn't a big deal at all.

I'd say the test might be, if you already have the tools to do it,
can envision the processes and procedures needed to do it,
you're probably qualified to do it.

Reminds me of a Cashier's window or an old military type pharmacy
window.

This Cashier was cautious and really didn't want anyone behind the
door, all business was over the solid door/shelf...but I'm here to do
an audit. "Can't come in"

A few weeks later I had the door removed from the Cashier's office and
the door stood in the hall next morning.

All because of a fire alarm sensor :-/

Nobody else said it, so I will- talk to your local code people and/or
your insurance carrier. The rulebook for schools and daycare would
probably apply. I don't think a residential door would pass muster, or
last long. I think you are looking at metal frame and fire-rated door,
and wired glass for the window. Leastways, that is what I have always
seen used in that application. And unless the room has another exit,
not sure a dutch door would be allowed- too confusing in the dark and smoke.

If your church is broke, check out Habitat ReStore, even if you have to
drive a couple towns over. The ones I have been in usually have a decent
selection of ripout commercial doors, and since Habitat is church-based,
they would likely cut you a break on the price.

I appreciate that. I'll check with the insurance company. This is a
little country church out in the middle of nowhere and I really doubt
the county/inspector cares. Still, we want to do things right.

A fire door doesn't make any sense because the wall is not going to be a
firewall. Originally it was just going to be a temporary partition, but
a wall is cheaper for this one. Other rooms are being walled off with
partitions...

If it's out in the middle of nowhere, all the more reason to pay
attention to fire codes, adequate exits, co and smoke detectors, etc.
The door should not, it seems, open inward for two reasons: hitting a
child who is sitting or standing behind the door, and for exit in case
of fire. Is it in a basement? Near furnace or water heater?

What about a plain, sturdy storm door with plexi instead of glass?

aem is right--check your local code.

If code requires a window in the door, then you'll likely have to have
one even if you make it a Dutch door. How else would you look in if
both halves of the door are closed?

'Round here, all glass within four feet of a door is required to be of
the safety variety--either tempered (breaks into crumbs), or laminated
(has a central layer of plastic like auto glass), or both.

Good advice there.

When I was going to install a Dutch door, my customer asked me to check
code on it before going ahead. So I talked to the local building
inspector (City of Oakland), who was very helpful. Basically, he asked
me what kind of door was there before (it was a hollow-core door), and
said that since the existing door wasn't fire-rated (and didn't need to
be), the Dutch door needn't be either.

So what I took away from this is that if one is installing a Dutch door
to replace an existing door, assuming that the existing door is
code-compliant, than the Dutch door should be built to the same spec as
the existing door. If the door is fire-rated, then the Dutch door needs
to be as well.

When growing up my dad's shop built on the back of the house
8' concrete... had just that. A large home made dutch door.

I support getting a solid fire door - they are heavy and will provide
support when cut. Might be a safety issue as well - save another headache.

The home made ones were built with 1/2" marine plywood. The ply was the
central section and large 6' wide boards framed it. They were 2x6's.
They were slotted to allow the ply within.

I think the idea of pre-hanging it in the first place is Great!!!

You may want to consider adding a shelf to the bottom half; usual way is
to reduce the height of the bottom door by the thickness of the shelf.
Add supports on both sides as needed.

If nothing else, make certain any dutch door for a nursery will support
kids hanging off of it and swinging wildly. It will happen, although
(presumably) against the rules, and the door needs to withstand the
weight and torque. This of course also calls for beefy hinges,
especially for the lower portion. I would not trust a hollow core door
for this.

Even if code doesn't require it, a glass (or plexiglass or whatever)
panel is a really good idea in this age of liability and lawsuits and
fears of child abuse, whether well-founded or not. Over the past few
years, they've installed glass panels in all the nursery, classroom, and
office doors in my church.

There is no such thing. It's just a semitransparent mirror--you can
see through it to whichever side has the brighter light. When used,
for example, in a police lineup, the bright light is on the lineup
side, the dim light on the witness side, so the lineup sees a mirror.

side then you can see the other way.

If parents need to see in and the kids need to NOT see out, maybe an
inexpensive monitor system could be installed. Modern electronics, cameras
and moinitors are plentiful and much cheaper than they used to be.

And if some problem kids are going to yell, perhaps some sound proofing.

To be more specific, the side you are able to see through tends to be poorly
lighted, the other side is very well lighted. If you reversed the
lighting, the mirror will almost work as well, they tend to be somewhat
directional.

I wasn't confused with his answer.
I was confused as to why he felt the need to wallow in pointless,
useless semantics.

There is no such thing. It's just a semitransparent mirror--you
can
see through it to whichever side has the brighter light. When
used,
for example, in a police lineup, the bright light is on the lineup
side, the dim light on the witness side, so the lineup sees a
mirror.
If you dim the lights on that side and turn them up on the witness
side then you can see the other way.

Hmmm, you say there is no such thing, then go on to describe how
that
very thing works.

I'm confused. :-)

The mirror is not directional, it is the lighting that makes it so.



Right, but google "one way mirror" and you get a thousand results with
the same thing you posted, including from companies that make them.

That's like telling someone there's no such thing as hamburger because
there's no ham in it. So what? We all no what we're talking about.

Read my reply to John.

Do you guys get woodies from bringing up pointless and useless
semantics? :-)

IIRC the burger got its name from the burg where it first showed up not from its constituents.

Hamburger = from Hamburg
Hot dog = from Frankfurt (both in Germany)

Since we've gone there....

Most churches have more than one light switch.
You don't need "all-light/no-light" for them to work.
Less-light/more-light works fine, as often does a direct light shining
on the "blind" side or simply unscrewing any bulb that is directly above
the door on the "seeing" side.
We're talking children here, not hardened criminals standing for a lineup.

I see. So with you it's "just the facts, ma'am", is that it? I guess
you're a regular Joe Friday.

Some of us actually offered useful advice to the OP and others of you....

Hmmm, which are useless again?

I don't have direct experience with police line-ups, but there
absolutely is vinyl or polyethylene sheeting that is more transparent
in one direction than in the other. It's almost white on one side,
and brown on the other, and people on the brown side can see through
it pretty well, but on the white side, the whiteness must make the
pupils close down and one really can't see anything on the other side.
Maybe if you put your eye right up to it, you could, but I don't know,
I haven't tried that.

I think I've seen other designs as well.

I don't see why a day care place couldn't use this. It doesn't have
any sharp edges.

The plastic can be used alone or it can be stuck to lexan or glass
sheeting. Even then it would be no more dangerous than a plain glass
window, maybe less.

If you can't find this at a fabric shop or plastic shop, email me and
I'll find out where we got it.
