Terrano with built-in insulation — a seamed steel roof for heated buildings and homes.
Terrano Izo is the insulated version of the Terrano panel, with a factory-fitted insulation core that reduces heat loss and condensation in heated spaces.
It suits homes, offices, and other heated buildings where you want the clean look of a seamed panel combined with better energy efficiency.
Advantages
- Factory-fitted insulation core reduces heat loss and condensation
- The same clean, seamed look as Terrano — now for heated spaces
- Suits homes, offices, and other heated buildings
- Seamed together on the roof — no visible screws
- Better energy efficiency without compromising on design
Why choose this panel
Innovative IZO system
In search of even more possibilities, we have combined the greatest advantages of the Terrano panel with innovative technology. As a result, we introduced the original IZO system from Blachotrapez — a unique system that minimises noise, stiffens the panel, and introduces thermal inertia.
The perfect product
The eye-catching visual effect is ensured by the latch lock technology, which provides an aesthetic connection of two panels. With the mini- and nano-wave technology, Terrano Izo also reflects the light, and the "waving" effect caused by stresses and slight unevenness of the ground is less visible. Terrano Izo also fits perfectly with KROP Gutter Systems, characterised by reliability and excellent functionality.
Easy assembly with the roofer in mind
The Terrano Izo panel is a "click" panel — a simplified version of standing-seam coverage. Properly mounted screws enable "longitudinal work". In addition, the panel's mounting part, the so-called valley flashing, stiffens the panel and has optimal mounting holes.
A modern production line
The production process uses the latest technologies based on the global leader's equipment. The process is fully automated and the production organisation is based on a standard that ensures greater efficiency. With individual identification of the order, the customer can be sure the entire process — from raw material to finished order — is fully controlled.

Colours
MAT-TK — 45-year warrantyFrom 223.13 DKK/m²
A classic polyester coating on hot-dip galvanised steel: the steel core is protected on both sides against corrosion, then finished with a primer and an organic polyester topcoat that gives the panel its colour, texture, and weather resistance. It is the most widely used coating system on the market — durable and cost-effective.
