Glass Partitions vs Open Plan: Which Office Layout Works Better 2026
The debate between fully open offices and glass-partitioned spaces has evolved significantly. Based on current research and our experience with hundreds of Lithuanian office fit-outs, here is a clear-headed comparison.
Noise and Concentration
Open plan is one of the leading causes of productivity loss in modern offices. Research consistently shows that noise is the main complaint — conversations, phone calls, keyboard noise all accumulate. Glass partitions with double glazing (Rw 36-42 dB) eliminate most conversational noise. Even single-glazed partitions (Rw 28-32 dB) create a meaningful buffer.
Glass partitions with acoustic glass can achieve Rw 44-50 dB — enough to hold a phone call without being overheard. This makes enclosed-but-visible spaces the current best practice for knowledge workers.
Natural Light — Partitions Win Here Too
This is where glass partitions beat both open plan (with dividers) and solid walls: they transmit natural light while creating acoustic separation. Clear glass transmits 90-95% of light. Frosted glass transmits 50-70%. Either option dramatically outperforms traditional gypsum board walls for light distribution.
Cost Comparison
Open plan with desks and screens: EUR 50-200 per sqm. Glass partitions (aluminium frame): EUR 150-220 per sqm. Traditional gypsum walls: EUR 40-70 per sqm construction + EUR 80-120 per sqm finishing. The total cost of gypsum approaches glass partitions when you account for finishing, painting, and reconfiguration costs over 3-5 years.
Flexibility
Open plan: maximum flexibility in theory, but low acoustic privacy. Gypsum walls: no flexibility whatsoever. Glass partitions: demountable, reusable, reconfigurable at relatively low cost. For fast-growing companies, this is a significant advantage.
Employee Wellbeing
Research from 2019-2024 consistently shows that employees in fully open offices report higher stress, more sick days, and lower satisfaction scores than those with some acoustic separation. The ideal modern office layout is not fully open nor fully closed — it is a mix of collaborative open zones and enclosed spaces for focus work.
Verdict
For most Lithuanian companies in 2026: use glass partitions for private offices (HR, management, meeting rooms) combined with genuinely open collaboration zones. Avoid the outdated model of 100% open plan. Glass partitions give you light, acoustic privacy, and visual connection simultaneously.
