Top Swing Fully Reversible Windows
Key features

Designed for performance and longevity

Every detail engineered to the Norwegian standard, where windows must perform in extreme climates for decades without failure.

  • Cleans from inside

    The sash reverses fully so the outer glass face can be cleaned from inside — no ladders or access equipment needed.

  • Nothing enters the room

    No part of the sash projects inward during operation. Curtains, blinds, and windowsill items are not disturbed.

  • Night lock as standard

    The sash can be held slightly open for ventilation while remaining secure against entry.

  • Child restrictor included

    Limits the opening arc so the sash cannot reverse fully when children are present.

  • No additional parts needed

    Supplied complete to full specification. No optional extras required to meet building regulations or cleaning standards.

  • Single or multiple sash

    Available as individual sashes or combined into a multiple-sash window for larger glazed elevations.

Made in Norway since 1957

How top swing fully reversible windows work

The sash opens outward, rotating on a horizontal axis. At a certain point in the opening the sash reverses fully, bringing the outer face inside the room so the glass can be cleaned without the need for ladders or access equipment. Once released, the sash can be returned to the closed position.

Crucially, no part of the sash projects into the room during operation. Curtains, blinds, and items on the windowsill are not disturbed — a practical advantage in bedrooms, kitchens, and any room where the sill is in use.

What's included as standard

Every Nordvest top swing fully reversible window is supplied complete:

  • Night lock position — the sash can be left slightly open for ventilation while remaining secure
  • Child restrictor — limits the opening arc to prevent the sash reversing fully when children are present
  • Blow back restrictor (optional) — prevents the sash from being forced open by wind pressure
  • Spilka Classic —  remarkable strength and effortless function
  • Full reversal mechanism — no additional fittings or tools required

This is the only window in the range where the full specification is met without optional extras. What you see is what you need.

Single and multiple sash

Top swing fully reversible windows can be supplied as a single sash or combined as multiple sash windows sharing a common frame. This makes them well suited to larger glazed elevations — new builds, extensions, and commercial projects — where a consistent appearance across multiple openings is required.

Available in a range of colours in both timber and aluminium-clad finish.

Why it's our most popular window

The top swing fully reversible has been the dominant window type in Scandinavia for decades. In Norway, where building standards are demanding and energy performance expectations are high, this is simply the standard window. Its popularity in the UK has grown steadily among self-builders, architects, and contractors who want a window that performs to a higher standard without the complexity of a tilt and turn mechanism.
