Anyone have experience with an Overhead Door (r) of this size? This is for a small hangar door in North Pole, Alaska. The R17 and air sealing is appealing and I've had great luck with their 16' doors for garages in this environment.
I've seen a few in use but mostly I see bifold doors or single piece hydra lift doors, which are way more expensive.
We do a lot of 40' doors. None of them are OHD but they are all engineered about the same. They work great, have faster opening speeds and they last well.
