The future of flush-mounted installations

Foam instead of plaster

The UI foam box is now available!


Foam socket boxes are revolutionising flush-mounted installation. No more tedious mixing of plaster - simply insert, fix, foam, done!
That's why we at f-tronic have also developed such a box, which is securely fixed in the wall using PU foam instead of plaster. A new method that saves time and considerably simplifies the installation process.

Unlike other manufacturers, the f-tronic flush-mounted foam socket box allows the use of any PU foam, which makes the application particularly flexible, and the unique foam distribution system on the back offers a resource-saving solution: the foam is distributed efficiently and evenly, ensuring high stability and saving material.

More space, less effort

30% more installation space and faster installation, thanks to fixing with foam instead of plaster, compared to conventional flush-mounted boxes.

Efficient foam distribution

The innovative distribution system guides the foam precisely to where it is needed - for maximum hold and minimum waste of material.

Secure hold

Thanks to the integrated lamellae, the box remains firmly anchored in the masonry even without foam, regardless of the type of stone.

Stable connection

Flexible plug-in/sliding system for stable, side-neutral connection of multiple sockets.

Comfortable through-wiring

Fully insulated, airtight connection from box to box possible. For safe and efficient installation, ideal for pre-assembled combinations.

Airtight installation

Thanks to f5 membrane technology, the entire installation remains reliably airtight - perfect sealing around pipes and cables.

Perfect alignment

Triple screw domes enable precise and easy adjustment of the devices, for fast, safe and precise installation.

The UI foam box can be installed with any commercially available PU foam.
