## About

Based in the United States, Alpen High Performance Products, Inc. operates as a B2B and residential high-performance windows, doors and architectural glass manufacturer, providing custom energy-efficient glazing solutions.

Based in Colorado, United States and founded in 1981, Alpen High Performance Products, Inc., formerly known as Alpen Energy Group, provides high-efficiency windows, doors and commercial glass for the building materials sector. Founder Robert Clarke has been associated with the company since December 1981, while Brad Begin purchased the company in 2006 and later became board chairperson. As of August 2026, the company is led by CEO Andrew Zech, who replaced former CEO Brad Begin after Alpen announced the leadership change in December 2023. In July 2026, Alpen High Performance Products, Inc. raised USD 6 million in series B funding co-led by new investors Inherent and Arborview Capital.

The company works with homeowners, architects, builders, commercial project teams and window manufacturers to provide custom high-performance windows, doors, secondary glazing and insulated glass units. Its product portfolio includes Zenith, Tyrol, Aspekt+, WinSert, fiberglass and fiber-reinforced uPVC systems, plus thin triple and quad-pane glass technologies. These products are designed to improve thermal efficiency, reduce condensation, support Passive House construction and meet rigorous energy standards. Alpen also supports architects through specification-friendly resources, standardized project specs, design manuals, and technical product options for residential, commercial and existing-building applications.

The company’s revenue is generated by manufacturing and selling energy-efficient window, door, secondary glazing and architectural glass solutions to residential and commercial customers. Alpen appears to transact through project quotes, direct sales to homeowners, architects and builders, commercial building projects, and a nationwide dealer network. The company also supplies thin glass insulated glass units to other North American window and door manufacturers, creating a B2B revenue channel alongside its residential and commercial project-based sales.

The company will use the July 2026 funding to further scale manufacturing operations and meet market demand for its advanced building materials. The company also states the financing positions it to optimize manufacturing operations and expand capacity.
