Is 7040 a non-standard window size?

[quickdraw]

Recently a client was told that they could get an 8040 wdw for cheaper than they can get a 7040. Is this true?

I know that 3040 and 5040 are very common wdw sizes. Should I stick to even numbers after that?

Check with the suppliers directly, forget hear-say.

I just spent 5 minutes wandering around the Anderson web site. That sure is one unhelpful website.

I also did a google search and got a lot of pages about Microsoft Windows.

It depends on the type of window and window company
but a 7 foot window , in my books is not more expensive then a 8 foot
in my book a 7040 is 152 dollars less than a 8040
however, when you get into custom size, it can be more, say that 7 foot window is really a 7 foot 7, your paying the price for an 8 foot ( a 7'6 is still cheaper then an 80)
and with spans, etc, your header for a 7 foot is the same as an 8 foot
so why not go 8 foot if you can, I love windows and lite.
so, I design/build homes and sell many building materilas, so my answer is based on that.
oops wait a second. are you comparing window prices with big box stores supplying windows, thats a different story
box stores only sell and push fast moving sizes, colors, profits
anything out of the ordinray for them is $$$$$$$$$

Rachel-

I'm assuming you're talking about sliding windows. Most manufacturers (at least the national ones, I can't speak for your local shops) make a sliding window up to about 6' 0" wide, so a 6040 in your case. I'm not familiar with a manufacturer (Andersen, Marvin, Pella, Kolbe, Eagle, Jeld-Wen etc.) that makes a 7040 window. It would have to be a custom so far as I know.

An 8040 is usually a triple slider, with a fixed picture in the center and two flankers that slide inward.

Hope this helps.

Thanks Josh,

I love big windows too. However they are often problematic here in California where we need lots of shear and must also keep the glazing under a certain amount for energy efficiency.

If you ever drive around recent California Developments you will note that all the windows are atleast 48" from every corner. You can get them closer to the corners it just takes engineering, extra money and sometimes requires steel!

Thank you Steve,

That was very helpful!

Rachel, Check with your local supplier- they should have a brochure or booklet with all the standard sizes of the brands they sell.

I have a couple sitting on the shelf over the computer and use them daily.

Depending on the brand and supplier, sometimes special order sizes are not that costly. Ask a knowledgeable sales rep to make a call for you.

OUT HERE IN PHOENIX NO ENGINEERING REQUIRED UNTIL A
WINDOW OR DOOR IS LESS THAN 2'8". YOU CAN USE A SIMPSON SHEAR WALL FOR LESS THAN 2'8" BUT IN THE LONG RUN ENGINEERING IS CHEAPER THAN USING THE SIMPSON SHEAR WALL. I PAY 250 - 350 FOR THE STAMP

[Niuoka]

True, some things can be regional. Here we use a lot of a window called Milgard. they make single sliders up to 8050, bigger then that, like listed above you have to shift to an xox

in oregon, we have adopted a lot of californias earthquake and energy standards, however we can get to the 2'8 corner without engineering

[quickdraw]

Yeah,
I can put in an ABWP at 2'8" but they are pricey. It is cheaper to get it engineered.
Cheaper still just to put in 48" of BWP.

So it depends on the structure, the client, and ofcourse, the budget.

7040 standard here, but as XOX. Meets egress, but barely.

[Niuoka]

very true on egress
which is a good point,
all of us need to pay attention to egress when designing
