Roof System - Kalzip® DuoPlus E | Kalzip

The Kalzip DuoPlus E System retains all the qualities and benefits of a standard Kalzip standing seam roofing system. This hybrid system combines high-density thermal insulation with compressible glass mineral fiber insulation.

Kalzip’s DuoPlus E and Duo E roof systems offer a cost-effective and technically sound solution to achieve roof U-values as low as 0.10 W/m²/K.

Thermal Separation

The design concept of the Kalzip DuoPlus E and Kalzip Duo E roof systems involves a thermal separation between the outer roofing and the inner support structure. Various configurations are possible for the support structure, on which a suitable vapor barrier is applied. A layer of durable mineral wool or PIR/PUR insulation panels, with thicknesses of 100 or 140 mm, serves as continuous thermal separation.

On this thermal insulation, the specially designed rotary clip board E is secured to the steel trapezoidal profile beneath a shell or wooden substructure using approved fasteners. The primary function of this rotary clip is to distribute the external load from the clip to the thermal insulation and the underlying substructure.
