Straight answers

Buying impact-rated bifold doors

What makes an exterior bifold door custom?

The approved opening controls panel count, individual panel size, stack direction, threshold, glass, frame, finish, hardware and structural coordination. Every choice must resolve to a supported manufacturing configuration.

Why is pricing reviewed instead of shown as a stock amount?

Opening size, panel layout, glass, threshold, hardware, freight, unloading and installation can change the final amount. A reviewed quote keeps those facts attached to the exact system.
