I have repaired and upgraded a lot of hangar door in my career and I must say that Diamond doors are by far the best I had to work with. They are very safe to operate, sturdy, well documented… not only do they have a superior product, the staff was very fast to answer my questions as well.

We absolutely looove it. We also did the optional auto lock system that allows the door to open and close with the push of a button. It’s amazing… I can fly over, hit the button, and the door is open ready for me to taxi right in. It’s made the building way more usable and user friendly versus the four panel sliding doors I had before.

Our insulation package helps you lower your energy bill and maintain a consistent interior temperature year around. As an added bonus, it’s quick and easy to install. It’s a simpler and more effective choice compared to other insulation options.

Polycarbonate Custom Finish

Polycarbonate sheeting is a great option for allowing natural light into your hangar without sacrificing privacy. Our durable sheets are easy to install and allow you to customize the look of your hangar. We offer two types of sheeting depending on your insulation needs.

Hangar Door Windows

Like polycarbonate sheeting, windows are a good choice for natural light. Install your windows in the top half of your door for lighting, or in the bottom half to easily see what’s happening outside your hangar.
