Intelligent Design

Deceuninck’s unique Monorail is a contemporary, high performance Sliding Door System. It’s perfect for very wide openings and ideal for homeowners looking to make the most of great views and their indoor/outdoor living space.

Monorail opens up space between the home and the garden, balcony or terrace. It glides rather than slides, silently, securely and effortlessly on high quality nylon rollers, and provides excellent weather and thermal performance. It demonstrates the kind of intelligent design and thinking that makes Deceuninck products market leaders.
