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:

• Poroton / Brick
• Ytong
• Sand-lime brick
• Solid wood
• Concrete
• Pumice
• EPS (Styrofoam)
• XPS (Styrodur)
• PU insulation boards
• Wood fiber insulation
• Wood chip cladding stone

The Thermo Box system is ideal for installation in older buildings. Thanks to its membrane locking teeth, the Thermo Box can be secured anywhere, even when significant material has already been removed. For flush installation on already plastered walls, simply break off the plaster stop and insert the box completely.

The Thermo Box is always the right choice because it holds in any material.

It can be used in the following masonry:

• Poroton / Brick
• Ytong
• Sand-lime brick
• Solid wood
• Concrete
• Pumice
• EPS (Styrofoam)
• XPS (Styrodur)
• PU insulation boards
• Wood fiber insulation
• Wood chip cladding stone

The integrated plaster stop of the Thermo Box ensures flush installation according to DIN standards. If necessary, all conventional leveling rings fit the Thermo Boxes.

Thanks to the membrane locking teeth, the Thermo Boxes stay firmly in the drilled hole as soon as they’re inserted – even without foam. This allows the boxes to be installed pre-wired/pre-piped. For multiple combinations, the SCS Connection Technology provides additional stability, the connecting bar can be quickly and easily removed if necessary.

This means you can first drill the hole with the High Speed Driller and then mill the slots directly before inserting the Thermo Box and foaming it. This eliminates the risk of damaging the boxes. Furthermore, this method saves you up to 70 percent of your working time.

Our Thermo Box system is VDE-certified and suitable for thermal bridge-free installation. Good to know: Gypsum is not permitted in exterior walls or damp rooms due to the risk of mold growth.

Our Thermo Foam is suitable for all applications. The Thermo Foam meets DGNB quality levels 1 and 2. The Thermo Foam ECO meets DGNB quality levels 3 and 4. This enables sustainable construction methods in accordance with KfW funding programs.

The Primo Thermo Electronics Box eliminates time-consuming plastering, it’s easily installed in seconds using Thermo Foam. The box offers ample space for network cables, KNX systems, and other fieldbuses for building automation. 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.

No, a hole must be drilled with a 74 mm drill bit for the Primo Q series cavity wall boxes.

With a diameter of 74 mm, the halogen-free and airtight Qnect cavity wall box (depth 62 mm or 49 mm) offers significantly more installation space than conventional electronical boxes. In the case of multiple combinations, the Q series boxes can also be firmly connected to one another at the standardized combination distance of 71 mm. The SCS connection technology with a large-area connection membrane, including Cable-Plopp technology enables easy through-wiring without connecting pieces. This noticeably saves your working time!

The cavity wall boxes of the Q-Series are all halogen-free and airtight, offering you numerous advantages and application possibilities in a single box. With a diameter of 74 mm, it offers significantly more installation space than conventional electronical boxes. In the case of multiple combinations, the boxes can also be firmly connected to one another at the standardized combination distance of 71 mm. The SCS connection technology with a large-area connection membrane, including Cable-Plopp technology enables easy through-wiring without connecting pieces. This noticeably saves you working time

Thanks to its mounting claw, the Qnect can be fixed to panels with a thickness of 0 to 37 mm — something that’s not possible with standard cavity wall boxes. In addition, the box features a total of 8 screw domes, allowing flexible alignment. When installing the UniQ from the rear, no screwing is required at all, resulting in significant time savings.

Yes, as the UniQ is larger than a conventional cavity wall box, it offers significantly more installation space. In the case of multiple combinations, the boxes can also be firmly connected to one another at the standardized combination distance of 71 mm. The SCS connection bridge can then simply be broken out. Like this also pre-wired devices can be installed in a time saving way.

The Qnect is suitable for a wall thickness of approx. 2 mm or more:

• OSB-board
• Wood board
• Plasterboard
• Metal

The UniQ is suitable for double planked walls made of:

• OSB-board
• Wood board
• Plasterboard

In general no, but that’s why we developed the Qnect sound insulation box. Thanks to sound-absorbing materials and sound-optimized membranes, it provides a protection rate of 60 dB.

Yes, the cavity wall boxes of the Q series offer secure cable fixing thanks to cable retention up to 2 kg /20N.

It is advisable to drill the hole for the UniQ from the front side. On the one hand, this allows you to mark and drill out the boxes exactly according to the installation plan. Secondly, drilling from the front is cleaner, as there is a risk of fraying the plasterboard, for example, when drilling from the back.

DIN 18229 (General regulations for construction work) requires, that damage and impairment to other trades must be avoided during the execution of work.

We recommend discussing and agreeing the handling with the cable holder during the construction meeting. Subsequently, all trades (electricians, drywall builders, building owner) have advantages, e.g. no search work, no filling work, no torn out insulation.

What is the most expensive thing on the construction site? Working time! The cable holder eliminates unnecessary search drillings for the electrician and rework for the drywall builder and plasterer. There is also no need for a second measurement.

DIN 18229 (General regulations for construction work) requires, that damage and impairment to other trades must be avoided during the execution of work.

We recommend discussing and agreeing the handling of the multi box during the construction meeting. Subsequently, all trades (electricians, drywall builders, builder) have advantages, for example, no search work, no filling work, no torn out insulation.

What is the most expensive thing on the construction site? Working time! The multi box eliminates unnecessary search drillings for the electrician and rework for the drywall builder and plasterer. There is also no need for a second measurement.

Its great advantage is that you only have to mark them once. There is no need to align the box afterwards. Our Bohr-Fixx is the perfect component part for this. The right-hand rotation of the screwdriver or drill cuts an opening in hollow walls, e.g. made of wood, plasterboard or mineral fiber, while the left-hand rotation ejects the drill core fully automatically and without effort.

A 74 mm drill hole must be drilled in the rafter insulation for the Uni-Flexx.

If the Uni-Flexx and the XL 150 installation housing are installed under the foil, ideal thermal management is ensured. If holes are drilled through the foil afterwards, they must be professionally sealed.

Any standard available 4-drill bit from 38 mm to 127 mm fits on the Bohr-Fixx.

No problem, we have the M2 or M3 for that.

Yes, the M1 is slightly more expensive than competitor products. However, what is the most expensive thing on the construction site? Working time! Thanks to the modern membrane technology, the boxes are absolutely concrete-tight and cables and conduits can be inserted without tools. The integrated conduit grip ensures reliable strain relief – there is no need for tedious reworking or subsequent conduit cutting, which saves a lot of working time.

With the M1, you have the huge advantage that you only need one box for the entire concrete installation. The M1 can be used as an appliance junction box, wing concrete box, ceiling junction box, large conduit box or electronics box. Not only does this reduce your storage costs, but there is also no risk of the fitter picking up the wrong product.

Yes, thanks to the conduit grip of the membrane boxes, everything is securely strain-relieved and absolutely concrete-tight.

Yes, the wings fit all Primo concrete products: Membrane boxes, installation housings, universal junction boxes, grommets, sleeves and wall & ceiling transitions.

Yes, the membrane sealing lip prevents concrete laitance from running in between the formwork and the M1/M2/M3.

We did this deliberately because it is always dirty on the construction site. If there is dirt in the thread and you turn the ceiling hook in, it can happen that you twist off the thread.

Yes, that has been tested. In addition, we already have many satisfied customers who install our concrete boxes.

For this, we have the special M1 CEE in our range. This is a further development of our M1, which has already been installed millions of times and is designed to meet the special requirements of power installations.

Every conventional manufacturer of a CEE socket fits into the M1 CEE. It is therefore suitable for use with 16 A CEE device inserts.

The M1 CEE sealing ring with protection class IP 44 prevents moisture from ingressing the box, thereby meeting the required DIN 60309.

The XL-series is slightly more expensive than competitor products. However, what is the most expensive thing on the construction site? Working time! Thanks to the modern membrane technology, the installation housings are absolutely concrete-tight and cables and conduits can be inserted without tools. The integrated conduit grip ensures reliable strain relief – there is no need for tedious reworking or subsequent conduit cutting, which saves a lot of working time.

The installation housings of the XL series are perfect for mounting any built-in devices , for example luminaires, speakers or other built-in components.

It can be universally attached to all XL series installation housings.

The smart design of the installation housing enables optimal thermal management – even when using the transformer tunnel.

The universal junction box can be used very flexible. Thanks to the modern membrane technology, the boxes are absolutely concrete-tight and cables and conduits can be inserted without tools. The integrated conduit grip ensures safe strain relief – there is no need for tedious reworking or subsequent conduit cutting, which saves a lot of working time.

The 3-part structure with lid, box and front part allows, among other things, the placement of the front part before the reinforcement is being installed, which clearly differentiates the Primo universal junction box from the usual 2-part competitor products. The M40 entry is also unique on the market. The different front parts in 60 mm and 70 mm as well as an optional divider for two separate circuits within one box offer additional flexibility. Another advantage of the three-part universal junction box is that you can first nail on the base plate, then attach the box after the first layer of reinforcement, and finally screw on the lid – this way, the lid cannot get lost.

The universal junction box is available in two versions. You can choose between a front part with a diameter of 60 mm and a front part with a diameter of 70 mm.

Yes, for this purpose the use of optional divider is suitable. It can be inserted into the universal junction box in no time, allowing a clean and safe separation of the two circuits.

The C-series grommets are available in sizes M20, M25, M32 and M40. The C-series sleeves are available in sizes M20, M25 and M32.

The claw sleeves hold up to 380 N.

Thanks to the conduit grip technoglogy, the transitions and connectors guarantee absolutely safe strain relief – regardless of which conduit manufacturer is used. Additional fixation with adhesive tape or other expedients, as it was previously the case, is no longer necessary.

This is the support anchor. It supports the sleeve and gives it additional stability so that it does not break off.

Yes, because of the well-thought-out plug-in system of the C-series, all sizes can be combined safe and stable.

Yes, as our starting product is a claw sleeve, it is no problem to continue.

The Schalfix does not have to be disposed of as hazardous waste, but can be conveniently thrown away with regular plastic household waste.

Simply screw the adapter ring onto the ventilation sleeve without pre-drilling and the ventilation outlet can be fitted.

A 74 mm drill hole is sufficient to make the installation opening for the Uni-Flexx. This can be done by any fitter. The Primo high-speed drill in combination with our concrete core bit is ideal for this.

Alternatively, you can also drill the hole using a standard Ø 75 mm or Ø 82 mm drill bit. The resulting joint between the Uni-Flexx and the drilled hole is either covered by the device used (ceiling spotlight, loudspeaker, etc.) or can be closed during the planned filling process.

The formwork protector Quickstar is a clever helper in concrete construction to make transitions safe and stable in no time. It is particularly suitable for confined spaces and retains its shape even after concreting thanks to the stabilizing flap.

Our nailing aid for concrete construction products makes nailing the boxes easier. The 40 cm long nailer nails lids and boxes to the formwork without injuring your fingers – even if the second reinforcement has already been installed. The distance between the locating pins is 60 mm, so that any standard box lid can be picked up, positioned precisely and nailed in place.

For different wall thicknesses, we have the M1 (installation depth: 85 mm), the M2 (installation depth: 68 mm) and the M3 (installation depth: 48 mm) in our range. A matching push-on frame extends the box by 2.5 cm for even more clamping space.

For narrow luminaire bases, there is also a lid with a 35 mm luminaire outlet for every box in the M series.

With the M1, you have the huge advantage that you only need one box for the entire concrete installation. The M1 can be used as an appliance junction box, wing concrete box, ceiling junction box, large conduit box or electronics box. Not only does this reduce your storage costs, but there is also no risk of the fitter picking up the wrong product.

Yes, the M1, M2, and M3 can all be combined and connected from the rear to install boxes on opposite sides of the wall.

Yes, thanks to the SCS connection technology, the M-series boxes can be easily and sturdy lined up at a standardized distance of 71 mm.

For more clamping space in the box or for exact positioning of the conduit entry, the push-on frame is mounted directly onto the M1. The frame was also designed with SCS connection technology to ensure a consistently stable connection for multiple boxes.

Thanks to the conduit grip of the membrane boxes, they are absolutely concrete-tight and ensure reliable strain relief.

Yes, it works perfectly. We recommend our concrete pipe as the perfect combination for the Primo concrete construction program.
