DP180 Lift-and-Slide
Best where a large, unobstructed opening is required. Understand that comfort depends on how long the aperture is open and local wind/stack effects during use.
The Power of Revolving Doors
Where Energy Efficiency Meets Architectural Elegance
Modern Irish developments demand entrances that handle high volumes, maintain comfort and present a distinguished first impression. Revolving doors meet all three requirements and when specified, manufactured and installed by a single partner, they deliver exceptional performance. At NS Motion we deliver full-service design, manufacture and installation of entrance systems, using leading components such as Doorson 300C automation and Yawal aluminium façade systems, to create elegant, functional entrances for corporate offices, hotels, public buildings and retail destinations across Ireland.
SPEAK TO THE EXPERTS
Why Revolving Doors Still Matter in 2025
How revolving entrances protect your interior
A revolving door creates an airlock that helps keep warm air inside and cold air outside. Compare how air flows with a sliding/swing entrance versus a revolving entrance.

Better lobby comfort
The airlock helps stop cold draughts near reception and reduces temperature swings.
Less load on HVAC systems
With reduced uncontrolled air movement, heating and cooling plant can run less to maintain set points.
Fewer complaints about draughts
Maintaining the pressure plane at the boundary reduces discomfort and cold spots.
Premium entrance aesthetic
Curved glazing and coordinated finishes create a signature lobby that aligns with the architecture.
How the entrance actually works: sliding vs. revolving
Two different behaviours: a DP180 lift-and-slide creates a temporary open aperture (air can cross the envelope while open). A revolving entrance forms sealed cabins that rotate, maintaining the pressure boundary with only local exchange at the drum.

- Lift to unseal, slide to open, drop to reseal.
- While open, air can cross the boundary in both directions.
- When closed, gaskets compress and cross-flow stops.
Revolving Airlock
Designed to minimise infiltration. The pressure boundary is maintained while people pass through sealed cabins, reducing draughts and HVAC load.
How a revolving entrance keeps people moving and the heat inside
Step into a rotating cabin, ride through the drum and exit to the lobby. The airlock effect limits cold air entry and helps keep warm air indoors.
