TB-hortiroof sets a new standard

Our TB-Hortiroof is an advanced evolution of the widely used "Knikdek" in the horticulture sector. The package consists of custom-made sandwich panels with flat outer plates and diagonally sawn ends to perfectly fit our in-house developed and patented aluminum TB-Gutter system and ridge profile.

With this, the TB-Hortiroof becomes a fully integrated roof system that can be directly placed on the gutters of the Venlo substructure. The result is a sturdy, durable, waterproof, and condensation-free insulated sandwich roof for the Venlo structure.

During the development of the TB-Hortiroof, consideration was also given to the assembly, which is highly appreciated by field technicians.

For the specific characteristics of the aluminum TB-Gutter system, please refer to the corresponding chapter.

Weatherproof finish

A waterproof roof is obviously a requirement. The aluminum profiles developed by us and the proper connection of the sandwich panels in the system ensure a watertight finish.

Additionally, all gutter covers are equipped with an expansion profile to accommodate the expansion of the aluminum gutter cover profile.

All vertical seams of the sandwich panels and transitions of the aluminum profiles of the TB-Hortiroof are finished waterproof.

new construction or refurbishing

The TB-Hortiroof offers a light but solid roof and can be mounted on any Venlo substructure construction. This can be included as part of a new construction, but can also be mounted on an existing substructure. Together with the assembly of insulated façade panels, you can then relatively easily change part of your construction into an insulated Production area or Storage or Office spaces.

parts of THE HORTIROOF supplied

 As mentioned earlier, we offer the TB-Hortiroof as a complete package. In addition to custom-cut sandwich panels, this package includes all necessary aluminum profiles and the essential plastic core. The construction manual provides the technicians with detailed instructions for effortless assembly, including an overview of the required installation materials. All these components ensure an efficient and smooth installation of a waterproof and condensation-free roof


Basically you have the same options in coatings and colours as with the façade panels. However, we often recommend choosing a lighter color with a strong and colorfast Ultra-X-70-75μm or the HPS Ultra 200μm coating. As a result, the Knikdek reflects the solar radiation more effectively and your roof is well protected against the various weather influences.
