Timber is usually engineered or laminated to make sure it’s structurally resistant to warping or twisting and doorways are normally available with either a factory applied translucent blot or RAL color paint finish.
Timber folding doors typically offer slight sight lines since the individual door panels are normally hinged off each other without the use of additional mullions between each panel and therefore maximising visible glass locations.

Adapting bulky broad uPVC steel reinforced profiles that were initially designed for traditional hinged external doors meant glass sight lines were considerably reduced and the doorways used ugly face fixed hinges and exposed gearing that also sometimes posed a safety threat.
But some manufacturers have started to introduce the next generation of uPVC folding doors with slimmer profiles and hidden gearing that compare favourably with those of wood and aluminium. Heavy steel profile reinforcement is beginning to be replaced with lighter yet stronger recycled composite material that’s also more energy efficient.
