Solution matrix
| Space | Recommendation | Specification note |
|---|---|---|
| Conference rooms | Opaque roller, optional channels | Pair with solar for daytime |
| Classrooms | Room-darkening roller | Durable, cordless controls |
| Hotel guest rooms | Blackout roller + drapery | Overlap and edge coverage |
| Treatment rooms | Opaque, cleanable fabric | Privacy first |
| Media rooms | Blackout with side channels | Closest to full darkness |
Inside mounts leave a perimeter glow; channels reduce it.
Opaque shades closed against sun can build heat at the glass; consider ventilation and fabric backing.
Motorized groups help large rooms darken in one action.
