Your Questions Answered

Have a question? You're not alone. We've answered some of the most common questions about our turn in windows below, drawing from years of expertise helping homeowners and professionals achieve their vision.

What is a turn-in window?

A turn-in window is an inward-opening casement window hinged on a vertical edge that opens fully into the room. 

Unlike a tilt and turn window, it has a single turn mode only, without the tilt ventilation function. The inward-opening design allows easy internal cleaning, supports larger sash sizes than equivalent outward-opening hardware, and is well-suited to upper floors where external cleaning access is restricted.

What is the difference between a turn-in and a tilt and turn window?

A turn-in window offers inward-opening casement functionality only. 

A tilt and turn window adds a second handle position that tilts the top of the sash inward for background ventilation without fully opening the sash. 

If secure background ventilation is important - for instance, in occupied rooms overnight - the tilt and turn is the more versatile specification. If ventilation will be managed by other means, the turn-in is a simpler, cost-effective alternative.

Can turn-in windows accommodate larger sash sizes?

Yes. Inward-opening hardware supports greater sash weight than most outward-opening casement hardware, making turn-in windows suitable for larger openings.

This is a practical advantage in contemporary designs where large, clean-glazed windows are an architectural priority.

Are turn-in windows easy to clean?

Yes. The sash opens fully inward, giving complete access to both faces of the glass from inside the room.

This makes turn-in windows particularly well-suited to upper floors, where external cleaning access is impractical, and to apartment or multi-storey residential buildings.

Are turn-in windows energy efficient?

Yes. The inward-opening perimeter seal on turn-in windows, combined with multi-point hardware, delivers consistent thermal performance. 

In Passive House-specified profiles with 88mm laminated timber frames and triple glazing, whole-window Uw values around 0.70 W/m²K are achievable, meeting the Passive House Institute's 0.80 W/m²K threshold.

Are turn-in windows suitable for a Juliet balcony?

Yes. Select inward-opening windows, including turn-in configurations, can be adapted for use with a Juliet balcony (a glass balustrade fixed externally at sill level).

The window opens fully inward to the balustrade, providing the appearance and ventilation benefit of a balcony opening without a structural balcony projection.
