Inside Outside Guys | Clarkston Window and Door Special | October 11, 2026

Let me ask you something that I think is confusing to a lot of h- lot of people, anyone that is looking at windows that's never done it before, which is the benefits of the struct- stru- struct- structural integrity of fiberglass, and also the E values and the gas that goes inside.

Let's be honest, that's confusing for a lot of people.

Sure, sure.

So do us a favor, someone who's an expert at this, un-confuse it for us, please.

Sure.

Um, so first off, you know, uh, our products are a hybrid product.

Uh, they have fiberglass reinforcing in them, and also they are a welded vinyl product.

So you get kind of the strength of a fiberglass product, and you get the welded corner of a vinyl product.

In fact, our Ultra Star product line, um, and uh, that, that just was introduced about three years ago, you know, we actually just went through and had it retested.

We put, uh, new hardware on it, and we had to go through the whole testing process with this.

So we were shooting for a design pressure rating, what we call a DP rating in the industry, of a 50, which makes it a really strong window suitable for multi-story buildings, uh, high wind locations.

A DP 50 is kind of the target that you wanna get to, to really say you're a strong window.

Well, they tested this thing for a DP 50, it passed.

They tested it for a DP 55, it passed.

They went to 60, it passed.

65, it passed.

They got to 70, and it passed.

They were blown away at how much of an impact this fiberglass extruded reinforcing was-

But not blown away

... inside.

[laughs] Yeah, but not blown away.

Yeah, very good.

So were you actually, um, you know, maybe compressive strength or, or, or compression? I mean, how does that work?

So it literally is wind load testing.

So you can take our product, put it into a high-rise building, it's rated as a commercial product, and blow wind against it at high levels, and it passes.
