I think Don Young's thermally-broken aluminum window is one of the very best choices for Texas. About 50% of my business is their product. It's incredibly strong and durable, offers narrower frames - maximizing glass space, and it's unaffected by the intense Texas heat.
On the downside, it's not as efficient as vinyl or fiberglass. The SHGC is going to be slightly higher (.23) and the U-Value is going to be higher (.42).
They are going to be more expensive than the quotes you've had so far. Last year they introduced a casement window, and it's nice, but a bit bulky. Don Young is also somewhat restrictive on size limitations. All in all, I'd recommend you consider them since you really like bronze.
Thanks. Yes, I am looking for Don Young now. If they are priced competitively, then I will go in for them . My windows are very big - 8ft tall - so , I am assuming the strong aluminum frame will be better.
Also, how strong is the bronze color on Don Young ? I mean , do they scratch easily with regular wear and tear. B'cos scratches on a Bronze color look real bad.
And you said it's not as efficient as Vinyl . So , how much difference are we talking about in real world terms regarding future energy bills or insulation costs. The U value and SGHC values being high - is this a deal breaker ?
