The trio
For flush mounting
The Thermo box series consists of three boxes: the flat Thermo box, the Thermo box and the Thermo electronics box. We paid special attention to a uniform standard for all boxes for standard-compliant and at the same time convenient flush mounting installation. To achieve maximum drilling accuracy, we also recommend the Primo Flush mounting drilling template. It is suitable for all masonry.

Primo benefits
at a glance
FOAM TECHNOLOGY
The specially developed Thermo foam fixes the box airtight and without thermal bridges in just 2 seconds in aerated concrete, brick or limestone block.
MEMBRANE TEETH
The membrane-coated ratchet teeth compensate for unevenness in the drill hole.
PLASTER STOP
The plaster stop prevents the box from being pushed too far into the drill hole – the clever electrician saves the use of a plaster compensation ring.
UNIVERSAL PLASTER COVER
The standardised plaster cover in red fits perfectly and protects the screw bosses and the interior of the box against the ingress of plaster. The box is quickly found thanks to the red pins of the signal cover.
MEMBRANE TECHNOLOGY
The membrane is opened flexibly using a commercially available cutter for conduits or cables.
SCS TECHNOLOGY
The boxes are firmly connected to one another via the SCS rail. In case of multiple connections, break out the web between the rails using the Primo Box cutter.
In just a few steps
Perfectly installed
Drill
Mark the first box and drill with Primo High-speed drill and 82 mm holesaw.
Expand
Insert the Drilling template into the first hole. Tighten the lever and align it using the integrated spirit level. Drill more holes by moving the template.
Mill a box, or for…
In the case of single boxes, drill the slot from above for the box recess. Retain a short web between the recess and the slit and only break out after foaming.
… multiple combination
In the case of multiple boxes, the slot is milled next to the boxes. Again, when connecting the slit and the borehole, retain a short web. Observe the installation zone!
Moisten
Moisten the hole so that the foam swells better.
Insert
Insert the box up to the plaster stop. In this way the box is mounted exactly flush.
Fix
The box is fixed by the membrane teeth and unevenness in the hole is compensated.
Foam
Use the Foam pistol to break out the predetermined breaking point in the rear of the box and inject the foam until the box is completely enclosed, airtight and thermal bridge-free.
Break out
After 20-30 minutes, the foam is cut-resistant. Then break out the remaining web. The box remains firmly fixed in the hole.
Wire up
Open the membrane with the cutter knife or pierce with the cables and insert them.
Protect
Attach the convex plaster cover to the 61 mm opening of the box to protect the screw bosses and the inside of the box, and to reduce the plaster application.
Push in, or…
Push the cover in with your finger or screwdriver. When it pops outwards, a clean contour is created without offsets in the plaster. Then remove the cover.
… drill out
Alternatively, expose the plaster cover with a 68 mm holesaw and remove it at the same time.
Connect
For multiple connections, remove the web between the SCS rails with the Box cutter.
Wire through
Once the web is cut through, wire up electronic components in the large installation space or directly insert pre-wired devices.

Frequently asked questions
FAQ
TO USE SUCH A SYSTEM I HAVE TO DRILL PERFECT HOLES – IS THAT POSSIBLE?
Well thought out! Because with some materials, clean drilling becomes a challenge even for the most experienced professional. The Primo Drilling template is just the job for this. Measure and mark the first hole, then insert the Drilling template, fasten it and align it exactly horizontally and vertically with the integrated spirit level. The holes are drilled at the standardised spacing in the perfect size. For multiple holes, simply move the Drilling template one hole further along, align it and drill further in a flash. ADDITIONAL TREAT: All our Thermo boxes have membrane teeth, so that inaccuracies of the hole are compensated and fixed firmly in the hole. With Primo it’s child’s play!
WHY IS THE PRICE OF THE THERMO BOX SO HIGH?
If you compare the Primo Thermo box with the standard flush mounting box from the DIY store, then that is correct. But who would compare a Matchbox car to a Porsche? Primo stands for high-value premium quality “Made in Germany”, which provides for efficiency and time savings and facilitates the daily work of electrical professionals. Thanks to the special foaming technology, the Primo Thermo boxes are installed airtight and thermal bridge-free in seconds. For example, as opposed to conventional plaster with water bucket, mixer and 25 kg plaster sack, only a 750 ml can of Thermo foam is required for fixing 70 to 100 Thermo boxes. Foaming itself requires 2 seconds of time per box compared to 2 – 3 minutes for plastering. With Primo, therefore, the following applies: invest in good quality, save energy, gain time and ensure energy efficiency!
IS THE BOX ALSO SUITABLE FOR OLD BUILDINGS?
Uneven walls, brittle plaster and the constant surprise of what is hidden behind the walls make the electrical installation in old buildings a real challenge. The Thermo box is a real jewel in our collection, but in this special situation we would recommend the Primo Multi box. Among other things, it is height-adjustable and can be individually adjusted for the renovation of old buildings.
