Exit Window - Rhode Island ?

[Sal's Dad]

Hello, I am new to this forum, A DIYer with a background in construction; I am currently building a detached garage with an apartment above, in Rhode Island.

In the one-bedroom apartment, I have a particular casement window in mind, but it is unclear whether it meets code, depending on the hardware selected; it is certainly close to 5.7 SF, in any case it seems like a big opening to me.

But then I made the mistake of looking at the RI Building code, and found this:

R310.1.1 Delete R310.1.1 and substitute the following:

R310.1.1 Minimum opening area.

All emergency and rescue openings shall have a minimum net clear opening of 4.4 square feet. Where the net clear opening dimensions specified below can be met only with window sashes easily removable without the use of keys, tools or excessive force, the net clear opening area shall be 5.7 square feet.

Now I am usually pretty good at reading comprehension, but I am lost here! Presumably the intention is that a 4.4SF opening is OK, UNLESS you need tools, keys, or force, in which case the larger opening is needed. But that's not what it says. Or is it?

If I had a good relationship with the Codes Officer, it could be a fun conversation, but he has been an unhelpful curmudgeon so far, and I don't want to come across as a smart-a--.

Ever seen language like this?

Thanks

Sal's Dad

Not in RI but, I would interpret the above as meaning 4.4 s.f during the normal operation of opening the window.

Some casement window hardware reduces the opening width during normal use. Normally requiring specialized hardware. It appears this Code amendment allows for the use of standard hardware by reducing the net opening to 4.4 vs. 5.7

welcome from another unhelpful curmudgeon,

But anyway, are you close to another city that may be able to answer your question, since it is RI wide?

sounds like the minimum is 4.4,

but if you have have sashes than, ""with window sashes easily removable without the use of keys, tools or excessive force, the net clear opening area shall be 5.7 square feet.""""

Sorry I do not speak Rhode Island

 

[cda]

All emergency and rescue openings shall have a minimum net clear opening of 4.4 square feet.

Where the net clear opening dimensions specified below

""""can be met only with window sashes easily removable """

without the use of keys, tools or excessive force

"""the net clear opening area shall be 5.7 square feet.""""""

 

[cda]

Maybe if the window does not open as in slide up or down or to the side, and you have to remove the window out of its frame, it has to be 5.7?

 

[ICE]

Everywhere else, the requirement is 5.7. Where did you find the code section that you quote? It sounds like something Jeff would come up with.

R310.1 Delete R310.1 and substitute the following:

R310.1 Emergency escape and rescue required.

Basements with habitable space and every sleeping room shall have at least one openable emergency escape and rescue window or exterior door opening for emergency escape and rescue.

SBC-2-2013 12

Where basements contain one or more sleeping rooms, emergency egress and rescue openings shall be required in each sleeping room, but shall not be required in adjoining areas of the basement.

Where openings are provided as a means of escape and rescue they shall have a sill height of not more than 44 inches (1118 mm) above the floor.

Where a door opening having a threshold below the adjacent ground elevation serves as an emergency escape and rescue opening and is provided with a bulkhead enclosure, the bulkhead enclosure shall comply with Section R310.3 .

The net clear opening dimensions required by this section shall be obtained by the normal operation of the window or door opening from the inside.

Escape and rescue window openings with a finished sill height below the adjacent ground elevation shall be provided with a window well in accordance with Section R310.2.

Exception: Basements with habitable space not used for bedrooms shall not require an emergency escape under any one of the following two conditions:

1. Residential sprinkler systems conforming to NFPA 13D or RP 2904 latest edition shall be installed throughout all areas of the basement or cellar, or

2. Fuel-fired equipment shall be separated from the habitable room and means of egress with one (1) hour rated construction and 20 minute rated opening protectives.

R310.1.1 Delete R310.1.1 and substitute the following:

R310.1.1 Minimum opening area.

All emergency and rescue openings shall have a minimum net clear opening of 4.4 square feet. Where the net clear opening dimensions specified below can be met only with window sashes easily removable without the use of keys, tools or excessive force, the net clear opening area shall be 5.7 square feet.

R310.6 Add the following new section R310.6

R310.6 Basement or Cellar Windows:

Except as may be otherwise provided for habitable or occupiable rooms, at least two (2) operable windows 12” x 32” nominal size shall be installed reasonably remote from each other. Security devices shall not unreasonably impede the use of these windows for light, ventilation or firefighting purposes.

Delete R311.3

but not the RI IBC:::

Congratulations Sal's Dad, this is the first time that absolutely everybody is stumped.

 

[MASSDRIVER]

Is a rescue or emergency opening the same as egress? It almost sounds like they need it to be easily removable from the inside with a responder involved on the outside.

[Sal's Dad]

the first time that absolutely everybody is stumped.

The first indication I was in trouble, the manufacturer's catalog listed this window as exit-compliant in one table (with appropriate hardware) but in another table, indicates it will NOT do. So I included a question about compliance in the price quote request I sent out. At the Big Orange store (in an adjoining state), the window guy said it does not meet the minimum, "but we don't interpret local building codes". That struck me as a strange disclaimer, so I looked up the RIBC. LOL, see if I do THAT again!

For a number of reasons, I strongly prefer this particular window, and it seems to meet the "spirit" of the code... So do I put the window in, and if the inspector flags it (unlikely), argue my case? Or seek approval in advance, despite the Curmudgeon's prior reluctance to offer help/advice?

Mind posting the window and specs?

If you have a window that has the 4.4 opening and it opens normally either push up or the side you should be good to go.

If you actually have to take the window out if the frame you need 5.7

 

[MASSDRIVER]

This code appears to be specific for basements. So if you have a fixed window, something you don't want operable because of basement conditions, it has to be easily removable and larger.

No?

Brent.

 

[Sal's Dad]

Andersen CXW13

R.O approx 36x36

Opening (with straight-arm-hardware) 6.5

Width 30 1/8

Height 31 1/16

Looks plenty big to me, but the manufacturer and retailer seem unclear!

Brent.

The normal window requirement is different than the basement requirement

 

[MASSDRIVER]

The normal window requirement is different than the basement requirement

Yes, but the entire section he is pulling from is basement specific. It refferes to egress AND rescue windows. Plus windows 12 X 32, operable, separate from one another.

I don't think any of this applies to above ground construction. It's code for basements.

It seems to me that it easily meets the most restrictive of either of the requirements.............should be no problem.

As to the question of why the difference, I agree, if the window meets the 4.4 net through basic window functions, side slide, raise sash, it complies. If it requires anything further, removal of the window, etc..............then it must be 5.7 net.

Sorry my bad

You are correct

How does it open

Slide up

Slide to side

Or crank open

 

[fatboy]

Has to be a casement if the net clear opening is 6.5 s.f., based on the dimensions given.

 

[Sal's Dad]

Yes, it is a casement, available with special full-open hardware.

I am a bit confused as to whether the section I am looking at is basement-specific. Rhode Island has modified section 310.1 . If 310 is for basements only, where does the code address bedroom windows?

Thanks to all.

apparently RI did not amend that section, so it would be whatever the base code reads.

should be something like this::

remember the basement section has changed for RI

From the RI 2010 amendments to the 2009 IRC

R310.1 Delete R310.1 and substitute the following:R310.1 Emergency escape and rescue required.

Basements with habitable space and every sleeping room* shall have at least one openable emergency escape and rescue window or exterior door opening for emergency escape and rescue. [*emphasis added]

[*emphasis added]

Looks like RI could use a wordsmith. The 4.4 square feet requirement is ABOVE in the paragraph.

FWIW, the window listed meets the net clear opening, but does not meet the required sill height if installed with the head at 80" as would be typical.

Thanks reading that whole section wrong
