Guide to PVC Window Opening Types

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.
