glidwall? Anyone familiar with it?

[Scott Lyons]

Has anyone heard of this before? We are renovating a unit and a plaster wall or two has some water damage and the contractor said it needs glidwall and gave us an estimate of $2,600 to fix. Seems crazy high to me. Said without it the wall won't hold. We've used the contractor before and they did a good job and seemed like good people though price came in a lot higher than expected. Not much on google about it which makes me think there should be some other alternative.
