TRI-ROOF: In-roof photovoltaic installation for maximum aesthetics and efficiency

The TRI-ROOF in-roof PV is the perfect installation solution for anyone who values aesthetically pleasing PV without visible support systems. With this innovative solution, parts of the roof or the entire roof covering can be replaced. This creates a visually appealing and at the same time secure integration of the PV into the roof structure.

The advantages of TRI-ROOF+

  • Replaces parts of the roof or the entire roof covering

  • Closed module surface for highest aesthetics

  • Special profiles for maximum water impermeability

  • No thermal separation necessary thanks to floating bearing

  • Optimal load distribution and stability

  • Suitable for all common framed solar modules

  • Simple replacement of the solar modules

  • Bears the official "hard roofing" certification

  • Certified for wind and snow loads, statically tested

Efficient Installation and Sophisticated Design
Thanks to smart planning software and the patented SafeClick mounting system, this in-roof PV is extremely safe and easy to install on the roof. The PV are simply inserted into the mounting channels and are held securely in place by their own weight. No additional fastening of the modules is required. A standout feature is the clever drainage system, which ensures reliable water drainage. The in-roof system also offers flexible application options thanks to the ability to mount the modules vertically or horizontally. This opens up a wide range of design possibilities for realizing custom roof designs.

Tested and certified
TRI-ROOF meets the requirements for "hard roofing" by passing fire safety tests—this confirms its technical excellence and suitability for long-term construction projects.

Sustainability and Quality “Made in Europe”
Our PV are manufactured in Central Europe to the highest quality standards. All components of TRI-ROOF mounting system are statically tested and optimized for wind and snow loads to ensure reliability even under extreme weather conditions. All profiles and accessories manufactured under the original TRI-ROOF label are covered by a 15-year manufacturer’s warranty from the date of delivery. This warranty covers both the sound condition and the technical efficiency of the products.

Photovoltaic mounting for in-roof

The in-roof mounting system TRI-ROOF+ enables the installation of in-roofPV systems using all modular types from various manufacturers. The needs of customers who attach great importance to an aesthetically mounted solar system are thus optimally met.

TRI-ROOF+ 7

1. attach substructure

The roof integration system TRI-ROOF+ is mounted directly on the roof battens. Rainwater is safely drained away via the innovative water drainage system.

2. mount SafeClicks

The SafeClick elements are screwed onto the IP in-roof profile at the specified distance. The insert profile is then clicked into the SafeClick.

3. click in the insertion profiles

The insertion profiles are thus connected to the roof in a floating manner. Damage to the roof and module caused by thermal expansion is thus avoided.

4. insert modules

The modules are inserted into the profiles in a time-saving manner; additional fastening of the modules is completely unnecessary.

FAQs about the TRI-ROOF+ mounting system

An underlay is always recommended, as condensation may form under the module and drip into the roof via installation boxes.

The underlay membrane must be installed in such a way that any water that occurs is drained away unhindered under the module field.

The TR-D spacers are horizontal module shift locks. For TRI-ROOF+ systems, these are screwed in on the left and right before the last module of a row and pushed down to the lower SafeClick. For horizontal assembly, the TR-D spacer must be inserted after every third module, for vertical assembly after every fourth module.

TRI-ROOF+ always requires a horizontal substructure, such as wooden battens, wooden purlins or steel purlins.

The TRI-ROOF+ special adhesive for ridge sheets is applied to the lower UP-I profile as an 8 mm thick line across the entire rail width. The rail piece to be joined is pressed into the adhesive and screwed from above with a flat connector, 2 sliding nuts M10 and 2 hexagon nuts M10 x 25 A2. If this is not possible because there is a SafeClick at the joint, the flat connector can also be connected laterally or at the bottom in the grooves using M10 x 20 A2 hammerhead screws and M10 A2 self-locking nuts. For system depths greater than 12m, the flush-mounted I-connection is pushed together to 5mm, the 8mm adhesive cord is applied and the flat connector is only attached to the lower flush-mounted I-rail in order to minimise the stresses caused by temperature changes. If there is a SafeClick on the UP-I profile for this type of connection, the flat connector is fastened to the underside of the upper UP-I profile.
