The Mosaic Story

Born from Frustration. Built with Purpose.

Mosaic Windows & Doors was founded by two friends with a shared frustration:

There simply weren’t high-quality, modern aluminum window and door options available in the Idaho market—especially not from people who actually understood the builder’s experience.
Nate Bittner, a seasoned entrepreneur and custom home builder, and Simon Punka, a successful window installation company owner, crossed paths through a community of like-minded business leaders. What started as a few conversations turned into a mission: to manufacture precision-crafted, builder-first aluminum windows and doors that perform as beautifully as they look.
With a heart to grow God’s Kingdom, care for people, and build something lasting, Mosaic was born. What started as an idea has now grown into a rapidly expanding brand with dealer relationships across multiple states, a line of premium aluminum and glass products, and a commitment to excellence that runs deep.

This isn’t just a business—it’s a calling.

A mosaic of relationships, integrity, precision, and purpose.
