TB-hortiroof sets a new standard
Our TB-Hortiroof is an advanced development of the widely used "Knikdek" in the horticultural sector. The package consists of custom-made sandwich panels with a flat outer sheet and beveled edges, ensuring a perfect fit with our in-house developed and patented aluminum TB-Guttersystem and ridge profile.
This makes the TB-Hortiroof a fully integrated roofing system that can be directly installed onto the gutters of the Venlo substructure. The result is a robust, durable, waterproof, and condensation-free insulated sandwich roof for the Venlo structure.
During the development of the TB-Hortiroof, special attention was also given to the ease of installation, which is highly appreciated by field technicians.
For the specific features of the aluminum TB-Guttersystem, we refer to the corresponding chapter

waterproof and condensation-free
A waterproof deck is, of course, a necessity. All components of our TB-Hortiroof are designed with this in mind. A distinctive feature of our TB-Hortiroof system is the plastic core, which offers several advantages. For instance, the core functions as a thermal break, preventing thermal bridges and eliminating condensation. Additionally, the plastic core serves as a structural connection between the gutter tray and the gutter cover profile.
This smart combination ensures that the system, together with the EPDM expansion profile, effortlessly accommodates the expansion and contraction of the aluminum, without compromising the integrity or waterproofing of the gutter system.
The T-Bouwstrip offers a revolutionary solution for waterproof sealing of the joints between the sandwich panels of your pitched roof. This patented T-Bouwstrip replaces the time-consuming caulking of the seams, significantly increasing both efficiency and reliability in your project.
With this, all components of the TB-Hortiroof roof system guarantee a waterproof and condensation-free insulated deck for your Venlo greenhouse.

T-bouwstrip offers unique finish on every seam
Applying sealkit to the seams is a time-consuming task that also requires consistent precision during application. Improper application can after all lead to potential leaks.
Simple, efficient, and reliable!
- Easy to install: Thanks to its thoughtful design, the T-Bouwstrip can be quickly and effortlessly attached. No complex installations—just hassle-free application during panel assembly.
- Always a perfect fit: The T-Bouwstrip is always supplied in the exact length to match the chosen panel (cap size), ensuring a clean finish without any on-site adjustments.
- No room for error: The T-Bouwstrip can only be installed in one way, guaranteeing correct functionality and perfect installation every time.
- Completely waterproof: Our T-Bouwstrip fully covers the seams of the sandwich panels, providing optimal protection against moisture and leaks.
- Integral part of the TB-Hortiroof roofing system: The T-Bouwstrip is covered by the gutter cover at the gutter side and by the ridge profile at the top.
The T-Bouwstrip perfectly complements the already fully insulated TB-Hortiroof roofing system and is a new example of the quality and reliability that T-Bouwsystemen stands for.

COATINGS AND COLORS
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 TB-Hortiroof reflects the solar radiation more effectively and your roof is well protected against the various weather influences.
