Primo P400 ETICS Device Box for External Thermal Insulation Composite Systems

Electricians installing sockets, switches, or junction boxes on facades with external thermal insulation composite systems (ETICS) need a reliable, thermal-bridge-free mounting solution. The Primo P400 device box is built for exactly that: it sits flush within the insulation layer, accommodating insulation thicknesses from 100 to 400 mm. Its flame-retardant plastic body and EPS insulation core ensure a secure, airtight installation for standard flush-mounted inserts with a 60 mm diameter.

Key specifications

• Compatible with insulation thickness: 100 - 400 mm
• Outer diameter (flange): 150 mm
• Installation depth (device box): 70 mm
• Material: flame-retardant plastic, EPS insulation core
• Load capacity: up to 40 N (approx. 4 kg)
• Operating temperature: -25°C to +60°C
• Colour: Grey/White

Why choose it

This box prevents thermal bridges and ensures airtightness, maintaining the insulation's performance. Its multiple pre-punched cable entries simplify wiring, and the robust construction supports standard devices securely.

Ideal use cases

• Installing outdoor lights, cameras, or sockets on insulated facades
• Retrofitting electrical points in ETICS without compromising insulation
• New builds with external thermal insulation composite systems

Good to know

The Primo P400 is designed for flush mounting in the insulation layer and works with common flush-mounted inserts. Its grey/white colour blends with typical facade finishes.
