Does anyone know if is worth it to purchase the optional low-E 366 option in Jeldwen Premium Vinyl?

I am still working on what the differences are.  Standard is described as low-E.  The option is low-E 366.

I have attempted to attach their rating info.

thx Jim.

You need a .30 u-value or lower to qualify for the fed. tax credit.

OK, standard is u=0.31 ; shgc = 0.27 these are Low-E 272, and are energy star......no longer eligable for the meager tax credit.

the option I am thinking of is low-E 366, which is u=0.31, shgc = 0.18

So, quesiton is, is the shgc worth more money. I am working on how much.

The thing about the tax credit is:

1) it is not for new construciton, as I read it;
2) if it was, it is capped at 1500 total, except Geo, whcih I am doing, and there are many other things than widnwos you can take off.

Seems to not be a consideration.

thx. PS: It is odd that dealers are touting the tax credit, when the energy star site says it is only for rennovations.

Jim,

The tax credit for replacing windows in your primary residence is 30% of the cost of the product up to $1,500. A lower SHGC can help ease your cooling bills in NC (I believe that is where your profile listed you). I would double check to see why you can't get a window that meets the =< 0.30 u-factor and =< 0.30 SHGC. A $1500 tax credit should easily offset the additional cost.

Best of luck to you on your project!
