Fino a non molti anni fa si costruiva cercando di risparmiare in assoluto per tutta quella scelta sei materiali che non fossero finiture, ed in particolare non si isolavano gli edifici dall’esterno in modo adeguato, ottenendo costruzioni con pessime prestazioni.
Il costo di costruzione più basso per le imprese, andava a totale discapito per il portafoglio degli users degli edifici che ancor oggi con l’aumento fisiologico del costo del petrolio si trovano a fare i conti con dei costi di riscaldamento e raffrescamento degli edifici davvero troppo alti.
La sfida dei bravi progettisti oggi è quella di evitare la dispersione di calore durante l’inverno e contenere l’innalzamento della temperatura interna degli edifici nel periodo estivo.
Le pareti perimetrali sono tra le protagoniste di un buon comportamento di efficienza energetica della casa come dei grandi centri direzionali. L’obbiettivo deve essere non solo risparmio sulle spese di raffrescamento e riscaldamento ma il raggiungimento del benessere e della temperatura di comfort.
Per gli edifici di nuova costruzione la legge (Dlgs. n. 311/06) impone una serie di linee guida da osservare per l’isolamento termico.
Molto forse ancor di più si può fare per isolare sugli edifici già esistenti.
GLI ECOBONUS STATALI
Dal 1° luglio 2013 l’ecobonus è salito al 65% (fino al 31/12/2013 per le abitazioni singole; fino al 30 giugno 2014 per gli stabili condominiali che intervengono al rifacimento di pareti esterne, di tutto il tetto o del nuovo manto di copertura.
Oltre alle pareti nei vecchi edifici la dispersione può riguardare anche i serramenti e le coperture.
Una modalità risolutiva per isolare le pareti in modo adeguato è l’installazione di un “cappotto termico” dell’edificio. Se poi oltre all’isolante si lascia un intercapedine per consentire un passaggio d’aria si ottiene il tipico “effetto camino” di ventilazione della facciata ventilata. Il passaggio d’aria combatte il surriscaldamento della parete in estate e la conservazione dei materiali.
Gli isolanti specifici per la facciata ventilata sono pannelli rigidi studiati per essere velocemente montati in aderenza tra loro senza lasciare spazi vuoti non isolati, eliminando il rischio di ponti termici. Ci sono pannelli come ad esempio gli Isotec che sono già predisposti di montanti per poi applicare il rivestimento finale a vista della facciata.
Con la scelta dei materiali nelle murature si possono applicare isolamenti termici cosiddetti naturali o sintetici.
GLI ISOLANTI TERMICI NATURALI
Si chiamano naturali perché sono prevalentemente di origine naturale, ma esistono anche quelli in lana. Molti di questi materiali sono riciclabili e alcuni anche biodegradabili. Possono avere costi più elevati degli isolanti sintetici ma forniscono ottime prestazioni. Tra gli isolanti naturali troviamo i pannelli in fibra di legno (scarti del legno, resina e cemento) che però vengono applicati per isolare dall’interno o piuttosto per l’isolamento di coperture a falde, ottenendo coperture traspiranti e resistenti al fuoco. Con gli stessi scopi si possono utilizzare i pannelli in fibra di abete mineralizzata che offre ottimi benefici termoacustici potendo rimanere anche come pannello di finitura a vista.
Con la perlite espansa, da sola o miscelata in composti cementizi è possibile riempire intercapedini murarie, di pareti esterne ed interne. Può essere impiegata anche per isolare coperture a falde e solai.
Altro isolante naturale al 100% è il sughero ricavabile dalle piante del sughero con il procedimento della scorzatura.
Diverse le possibilità di utilizzo, soprattutto per quanto riguarda l’isolamento di tetti, piani e a falde. Si può applicare anche alle pareti e direttamente sul solaio del vespaio aerato. Trova impiego anche nei cassonetti degli avvolgibili.
ISOLANTI TERMICI SINTETICI
Questi isolanti si ricavano dalle sofisticate lavorazioni di materie prime di origine chimica e in certi casi naturale.
Il polistirene espanso, sinterizzato o estruso, deriva dallo stirene, un ricavato del petrolio che si trova anche in alcuni alimenti.
Il processo di sinterizzazione permette a queste perle estruse di saldarsi tra loro. Le perle, contenenti gas espandente, vengono trattate con vapore e sistemate in stampi, dove completano la loro espansione e si saldano tra loro.
Quando il rivestimento isolante (oltre ad essere posto dall’esterno) potrebbe rimanere a contatto con l’acqua bisogna utilizzare un isolante che non assorba acqua in alcun modo. In questi casi si utilizza il polistirene estruso che si ottiene inserendo il granulato di polistirene insieme a polistirene di riciclo in una macchina che la fonde e aggiunge degli espandenti e ignifuganti. Ne risulta una schiuma che viene sagomata (estrusa) attraverso un procedimento particolare.
Altro materiale molto diffuso per le sue prestazioni è la lana di roccia. Per produrla si utilizza una “miscela” di rocce di origine vulcanica o sedimentaria, con aggiunta di altri materiali. La lavorazione trasforma il tutto in fibre e poi in pannelli, feltri e rotoli.
In commercio la lana di roccia è reperibile anche con abbinata la barriera al vapore nel caso il progettista termotecnico rilevasse nella stratigrafia del muro la possibilità di formarsi di un punto di condensa.
