Yes, thanks. Let me try to hit both sides of that. So on the mix side, I'd say you're hitting it right. In terms of when we talk about mix shifts, where we're producing more laminate shingles versus strip shingles, our duration product, particularly as we can produce more of that and get that into the market that carries a different margin profile, and that's helping. And then our components business overall, we continue to add products. I talked in my prepared comments around house wrap product. We've got a full line of underlayment, starter, hip and ridge products, all of those continue to be pulled through at a higher rate, frankly, as we see contractors selling more systems in the home. So they want to package our complete offering when they go into the home. So it's all an Owens Corning roof.
But also we're seeing through our component strength the ability to sell products now under other kind of roofing materials. So we've developed products that go under metals and tiles and other kind of components. So those products generally carry very high margins as well. So as we're growing the Components business and getting more of that product true, that's also improving our mix overall. So those are the 2 pieces that you're hitting on.
On the lam capacity piece, this is something that's been an ongoing effort of the team over the last couple of years to really debottleneck and improve the line speeds and efficiencies within our existing footprint. So we are unique, in that we've got a great footprint, 13 manufacturing facilities across the U.S. So where we can go in, debottleneck or add a new laminator, like we're doing at our Medina, Ohio facility. That increases capacity inside an existing infrastructure and an existing workforce. And that means that when we turn these lines on, we get great productivity and great line speeds really quickly. And that's been helpful and then the steady cadence of the ability to produce that and ship more laminate products quarter-over-quarter.
And so part of this when we started was, we had a target to increase lam capacity by about 6 million squares. That's the equivalent of kind of a brand-new four way today across our network. So we put that volume closer to customers by spreading that out over our network, and we're on track to do that by the end of next year. So that's going to be a continued, I think, opportunity for us to improve our laminate mix, improve our duration mix and provide our contractors and distributors with great product going forward. And then from a financial standpoint, that gives us a better margin profile, and we'll continue to be, I think, a tailwind in our mix story as we go forward.
