Caixa de derivação encastrada KOPOS KEZ-300_KB para sistemas de isolamento térmico pelo exterior (ETICS) - laranja, 300 mm de espessura de isolamento

The KOPOS KEZ-300_KB is a professional flush-mounted junction box designed specifically for use in External Thermal Insulation Composite Systems (ETICS/EIFS). Manufactured from halogen-free polypropylene, this box provides a secure and durable enclosure for electrical installations within thick insulation layers. With a maximum insulation thickness of 300 mm and adjustable depth, it offers flexibility for various construction requirements.

Advantages

This junction box ensures reliable performance in demanding environments. Its halogen-free material composition enhances safety by reducing toxic smoke emission in case of fire. The box is UV-stable, making it suitable for long-term outdoor exposure. Pre-drilled cable entries (4x Ø20mm, 2x Ø25mm) simplify installation, while the IP30 rating (before sealing) provides basic protection against dust and moisture.

Suitable for

• Flush-mounted electrical installations in ETICS/EIFS facades
• New construction and renovation projects with thick insulation layers
• Applications requiring halogen-free and UV-stable components
• Installations where adjustable depth is needed to match insulation thickness
