One bottle of Thermo Foam is sufficient for approximately 100 boxes. For bricks, it’s sufficient for approximately 70 boxes, for Ytong, sand-lime brick and concrete, it’s sufficient for approximately 120 boxes.

The box only needs to be foamed 1/3 full, as the foam expands.

Our boxes aren’t just standard boxes; they can do a lot more! The Thermo Boxes are installed with Thermo Foam in just a few seconds. There’s no need for time-consuming plastering or mortaring as required with conventional products. The highlight: In combination with the Thermo Foam, the Thermo Boxes enable an airtight, thermal-bridge-free installation, including sound insulation.

In addition, the SCS Connection Technology allows multiple boxes to be lined up and to be securely connected. The connecting bar can then be easily removed for quick through-wiring or the installation of pre-wired devices. Furthermore, thanks to the Cable Pop, cables can be inserted completely without tools. All this makes the Primo Thermo Box system the fastest flush-mounting system in the world, saving you up to 70% of installation time for each individual Thermo Box.

On top, only one type of box is required for the entire flush-mounting installation. This saves storage costs and can also counteract the shortage of skilled workers, as there’s no risk of confusion during installation.

Yes, the Thermo Box can be used in the external thermal insulation composite system (ETICS). It can be used in the following masonry:

Additionally, the second opening can be easily opened, creating multiple combinations at the standardized spacing of 71 mm. Furthermore, the Primo Thermo Electronics Box can also be used as a soundproofing box.

We have just the right accessory for this: our Drilling Template. This drilling guide allows you to mill boxes with a standard hole spacing of 71 mm in line. It is attached with the quick-clamping function and aligned using integrated spirit levels. This allows you to create multiple combinations with just one measurement.

The major advantage of using the Drilling Template is that you only need to mark the hole once. There’s no need to adjust the box later. Our High Speed Driller is the perfect accessory for this. It enables faster and cleaner drilling. This reduces damage to the wall. Even in (filled) exterior walls, it prevents large-scale breakage of the drill hole and the resulting significant damage. The boxes can be installed more precisely, and material consumption is reduced.

No, but the Drilling Template is a practical tool that helps you save a lot of time while achieving a high-quality result. The Drilling Template ensures precise and clean drill holes. However, you can also install the Thermo Boxes without the Drilling Template.
