Special sizes are possible on request!

With their stepless adjustment to the room height, they allow you to comfortably and easily utilize your attic space.

One special advantage of our attic stairs is that they can also be installed within the ceiling cladding.
This means that the stairs can be positioned when there is a suspended ceiling.

Isotec SMART is exclusively available without an upper cover.

Hatch cover measuring 29 cm is available, optionally in higher sizes as well!
Featuring an internal pivot mechanism and a telescopic handrail, it provides smooth, user-friendly, and secure operation of the attic access.
The top step is located within the casing, allowing for easy exit onto the attic floor.

The Isotec SMART buttom cover is equipped with a 10 cm thick insulation made of mineral wool. The thermal insulation ensures that no heat is lost through the stairs, preventing unwanted energy losses. This allows you to improve the energy efficiency of your home and save on heating costs.

Preassembled - no tedious assembly required on the construction site!
Please make sure to follow the enclosed installation accessories and assembly instructions carefully!
