What is Fenestration and Perforation?

This option is featured on our Model 523 Security Shutter – which also happens to be one our most compact commercial designs to date! These two designs allow for retailers to have visibility even while the door is closed without sacrificing security!

What's a Garage Door Overlay?

Overlays are a trim like the kind seen in our Carriage House Collection. If you’re looking to add more curb appeal to your home, overlays help to add style! Our Model 6600 overlays come in wood grain or smooth finishes and the overlays on Models 9405 and 9700 are wood grain embossed steel.

Our wind load-rated doors are reinforced to withstand high wind events including storms. This reinforcement prevents buckling and catastrophic door failure. Additionally, these doors are less prone to being damaged from debris and also protect the structural integrity of your home’s walls and roof!
