EN 1264-X:2021 | Sistemi radianti annegati
ID 12503 | 04.01.2021 / Preview allegate
La norme EN 1264-X:2021 sono attualmente in revisione e saranno pubblicate nella nuova versione dopo la votazione finale da parte degli stati membri.
La norme EN 1264-X:2021 sono in revisione all'interno interno del WG9, gruppo di lavoro del CEN/TC 130, che a livello nazionale è seguito dalla commissione UNI/CTI 254 del Comitato Termotecnico Italiano.

Principali modifiche
- Nuove tipologie (anche senza isolante): inserite nella parte 1 della norma
- Nuove definizioni (parte 1)
- Materiali e conducibilità (parte 2)
- Isolante bugnato (parte 3)
- Temperatura massima sistemi radianti a soffitto (parte 3)
- Modifiche ai contenuti sull’installazione della parte 4
- Nuove tipologie (anche senza isolante): inserite nella parte 1 della norma
- Nuove definizioni (parte 1)
- Materiali e conducibilità (parte 2)
- Isolante bugnato (parte 3)
- Temperatura massima sistemi radianti a soffitto (parte 3)
- Modifiche ai contenuti sull’installazione della parte 4
Lo scopo della norma è, pertanto, cambiato:
- La EN 1264 fornisce le linee guida per i sistemi di riscaldamento e raffrescamento annegati - installati in edifici, residenziali e non (ad esempio uffici, edifici pubblici, commerciali e industriali) e si focalizza sul tema del comfort termico.
- La EN 1264 fornisce le linee guida per i sistemi di riscaldamento e raffreddamento idronici annegati all’interno degli ambienti da riscaldare o da raffrescare. Specifica inoltre l'uso di altri fluidi termovettori al posto dell'acqua.
- La EN 1264 specifica le caratteristiche standardizzate dei prodotti - calcolando e testando la potenza termica in riscaldamento per le certificazioni. Per la progettazione, la costruzione e il funzionamento di questi sistemi, vedere EN 1264-3 e EN 1264-4 per i tipi A, B, C, D, H, I e J.
- I sistemi descritti nella EN 1264 sono montati, direttamente o con supporti di fissaggio, in aderenza alla base strutturale delle superfici dell’edificio. La norma EN 1264 non si applica ai sistemi a controsoffitto che presentano un’intercapedine che consente la circolazione dell’aria tra il sistema stesso e la struttura dell’edificio. La resa termica di questi sistemi può essere determinata secondo EN 14037 e EN 14240.
