We have a team of professionals who are well-versed in all aspects and types, including cover glass draining. We offer our customers exceptional service that will not disappoint them at any point during their experience here! There are 2 ways to drain:

Weep Holes:

Weeping is the process in which water hits and disperses easily from a hole at the base of the track.


Installing draining pipes:

Installing drain pipes called PEX Pipes is a great way to get rid of any water that may land on your window panes. You can use this same lower profile track system which was designed for weep holes. You could also attach them directly onto panels in order not be limited by where there's access points on-site. We make attachments between connectors and pipes which helps reduce any hitting glass so it will move down our system before going wherever you would like the pipes to lead. Installing drain pipes is a simple and efficient way to get rid of excess water from your landscape.
