Modern PVC windows offer a variety of opening mechanisms — from classic to innovative. Let’s review the main types and share tips on choosing the best option for your space.
1.Turn windows
How it works: the sash swings around a vertical axis (inward or outward).
Pros: simple operation, full opening, easy cleaning.
Best for: living rooms, kitchens (if there’s enough space for the open sash).
Tip: keep 10–15 cm of clearance — avoid placing large furniture nearby.
2. Top‑Hung (Tilt) Windows
How it works: the sash tilts inward around a top horizontal axis.
Pros: safe ventilation (ideal for children’s rooms), reduced drafts.
Best for: bedrooms, children’s rooms, ground‑floor spaces.
Tip: combine with hinged sashes for full opening capability.
3. Tilt‑and‑Turn Windows
How it works: two modes — swing (handle horizontal) and tilt (handle vertical). Includes micro‑ventilation (handle at 45°).
Pros: versatility, adjustable airflow control.
Best for: any living spaces.
Tip: opt for hardware with anti‑mistake protection (e.g., Roto or Siegenia).
4. Sliding Windows
How it works: sashes slide along tracks parallel to the frame.
Pros: space‑saving, modern appearance.
Best for: balconies, loggias, small kitchens, terraces.
Tip: pair with at least one tilt‑and‑turn sash for intensive ventilation in living areas.
5. Fixed (Non‑Opening) Windows
How it works: a stationary design without moving parts.
Pros: maximum airtightness, lower cost.
Best for: hallways, utility rooms, panoramic glazing sections.
Tip: combine with opening sashes (per ГОСТ, at least one sash per room must be operable).
How to Choose?
For children’s rooms: top‑hung or tilt‑and‑turn with anti‑tamper mechanisms.
For kitchens: tilt‑and‑turn or hinged (for quick ventilation).
For balconies/loggias: sliding or hybrid systems.
For bedrooms: tilt‑and‑turn with micro‑ventilation mode.
Key Considerations:
Check hardware quality — it determines the mechanism’s lifespan.
Consider opening width: for large openings (over 1.5 m), sliding or dummy‑mullion systems work best.
Plan handle placement and opening direction during ordering.
