Our Products

Here at Rob Weiand Aluminum,  we believe in  using only the best products available from the best manufacturers and suppliers, because your home is worth it and our reputation depends on it.  The companies we partner with stand behind their products with pride, and so do we.


With our proven expertise in the industry, you can clearly see our promise of quality and innovation in every window and door we make. Not to mention how we go about making them. To us, it’s about creating an environment that brings out the best in everyone, and accepts nothing less. It’s about doing things the way they should be done, not necessarily the way they’ve always been done. It’s about giving back to our communities and the things that matter most. And it’s about family — ours, as well as yours.

At Wincore®, our philosophy is simple. It’s not about being the biggest. It’s about being the best.

Stocking the brands and products contractors want and need at a competitive price.
