I have been trying to swap out my garage doors for the last 2 years. Finally got around to doing it in October.
Just wanted to pass the idea along incase anyone wants to try something like this in their shop.
I purchased 3 Solid core office doors from someone on Craigslist.
I installed 3 window sashes i ordered from a local window factory.
Next step is to insulated the inside of the door with 1” rigid insulation.
Thanks For looking
