Sliding glass door: systems, price, install 2026
When to choose sliding over hinged. Minusco, Krona, Roca — system comparison and real prices.
A sliding glass door solves two problems: narrow approach where hinged won't open, or wide 2.5+ m openings. Systems differ: some are silent for years, others rattle within twelve months.
01Three main SPb systems
Minusco (Italy) — premium
Concealed rollers with SKF bearings, silent operation, 250 000-cycle life. 1.5 kg force opens a 60 kg door. Self-balanced, doesn't drift out of adjustment for years. From 78 000 ₽ for 90×210.
Krona Koblenz (Germany) — mid-tier
Quality with 200 000-cycle life. Slightly louder than Minusco, 25–30% cheaper. Standard for office and home use. From 56 000 ₽.
Roca / Hettich (Germany) — budget
Basic reliability. 100 000 cycles (10–12 years of typical use). From 38 000 ₽.
02When sliding makes sense
- Narrow corridor — hinged steals 60 cm of swing
- Wide 2+ m openings
- Kitchen-living transitions
- Full-wall closets
- Studio bedroom screens
| Config | Minusco | Krona | Roca |
|---|---|---|---|
| 1 door 90×210 | 78 000 ₽ | 56 000 ₽ | 38 000 ₽ |
| 2 doors synced | 134 000 ₽ | 96 000 ₽ | 62 000 ₽ |
| 1 door 120×260 | 132 000 ₽ | 98 000 ₽ | — |
| + soft-close | +12 000 ₽ | +8 400 ₽ | +6 200 ₽ |
Don't save on rollers. Roca at 38 000 ₽ runs 100 000 cycles then starts humming. Minusco at 78 000 ₽ stays silent for 250 000 cycles. Over 20 years the delta pays back in comfort.
