I was called by a potential client that has asked me to cleanup a shade install from a previous installer. Client has a large sliding glass door which is split into two (2) parts; one fixed and one that moves. On both sides of this door are two (2) glass windows.
The previous dealer installed three (3) blackout shades; one (1) on each of the side windows and one (1) large shade that covers both the fixed and movable panes. There is a 2"metal mullion between the windows.
Client would like total blackout when closed; since there are multiple shades, how would two (2) side channels mounted back-to-back along the mullion work? Has anyone done something like this before? If so, how did it work out? Other options?
