Paul Kellner
OWNER I SALES DIRECTOR I PaulK@HeritageWindow.com
NEW CONSTRUCTION/LIGHT COMMERCIAL SALES
This all kicked off in 1980 with the construction of a passive solar home for my family. Since then, I have developed advanced expertise in energy-efficient building systems, specializing in fenestration solutions for extreme climate conditions. I specify and source window and door systems that meet or exceed stringent energy performance requirements across commercial, residential, and historic preservation projects.
My projects span the US and Canada, and I am thrilled to have our Montana-based sales office up and running in 2026. -
