LMK GREENSTEP Metal Loft Ladder

The sectional design with a metal ladder provides stable access to an unused loft, offering a durable and safe solution for reaching the space above the ceiling. A maximum load capacity of up to 200 kg, steel steps with an anti-slip profile and a 3-section design help ensure secure and comfortable everyday use.

Thermal comfort and airtightness

The thermally insulated sandwich hatch, filled with polystyrene and finished with HDF boards on both sides, helps reduce heat transfer through the ceiling opening. A U-value of 1.0 W/m²K and Class 4 airtightness help limit uncontrolled airflow between the heated room and the cooler loft.

Aesthetics and easier installation

The white hatch blends discreetly into the ceiling, while the metal ladder in RAL 7022 gives the product a modern look. The loft ladder is supplied fully assembled, and the removable hatch makes installation and finishing work around the ceiling opening easier.

Metal ladder

The 3-section metal ladder provides stable access to the loft, while a maximum load capacity of up to 200 kg helps ensure safe and secure use. Finished in RAL 7022, the ladder has a modern look that works well in both residential and utility spaces.

Thermally insulated hatch

The sandwich-type hatch, finished with HDF boards on both sides and filled with polystyrene, helps reduce heat transfer through the ceiling opening. Its U-value of 1.0 W/m²K is particularly important when the loft ladder connects a heated hallway, landing or dressing room with a cooler loft.

Anti-slip steps

Steel steps with an anti-slip profile provide a more secure footing when climbing up and down. Each step is 34 cm wide and 8 cm deep, making it easier to place your foot securely, which is especially useful when carrying small items to the loft.

Adjustable stile ends

Adjustable stile ends allow the ladder length to be matched to the room height within the specified installation range. This helps ensure stable contact with the floor, including after the ladder has been trimmed according to the installation instructions. They also allow for minor length adjustments if the ladder has been cut slightly too short or if the finished floor height changes.
