Made in Austria: fire-retardant, highly insulating, airtight and stable steel loft ladder / attic ladder: Wippro ISOTEC

INNOVATIVE ATTIC LADDERS - SAFE AND COMFORTABLE

Wippro Isotec

With their stepless adjustment to the room height, they allow you to use your attic comfortably and easily.
A particular advantage of our attic stairs is that they can also be installed in the ceiling panelling.
This means that the staircase can also be installed with a suspended ceiling.
The optional availabletop cover, which can be opened automatically or manually, can be retrofitted at any time and can be opened either to the side or to the rear in the manual version. It serves both as additional insulation and as dust protection.
Hatch cover measuring 42 cm is available, optionally in higher sizes as well! Featuring a ball-bearing locking system and an internal pivot mechanism, along with 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 under 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, thus 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!
