La classe d\u2019emploi d\u2019un bois est d\u00e9termin\u00e9e par la norme NF EN 335-1 \u00e0 3 selon les risques d\u2019exposition \u00e0 l\u2019humidit\u00e9. Elle d\u00e9termine un degr\u00e9 de r\u00e9sistance par durabilit\u00e9 naturelle ou par traitement. Attention, la durabilit\u00e9 naturelle ne concerne que le c\u0153ur du bois (duramen) et non l\u2019aubier.<\/p>

Classe 1<\/span><\/strong>\u00a0: La classe 1 regroupe les bois secs en application int\u00e9rieure avec un taux d\u2019humidit\u00e9 toujours inf\u00e9rieur \u00e0 20 %. Ce sont des bois utilis\u00e9s pour les menuiseries int\u00e9rieures ou les zones \u00e0 l\u2019abri de l\u2019humidit\u00e9.<\/p>

Classe 2<\/span><\/strong>\u00a0: La classe 2 regroupe les bois secs qui peuvent \u00eatre occasionnellement en contact avec un taux d\u2019humidit\u00e9 sup\u00e9rieur \u00e0 20%, comme les ossatures et charpentes.<\/p>

Classe 3<\/span><\/strong>\u00a0: La classe 3 regroupe les bois qui peuvent \u00eatre fr\u00e9quemment en contact avec l\u2019humidit\u00e9, m\u00eame au-del\u00e0 de 20%. On utilise ce type de bois pour beaucoup de pi\u00e8ces de construction ainsi que les menuiseries ext\u00e9rieures telles que le bardage.<\/p>

Classe 4<\/span><\/strong>\u00a0: Les bois classe 4, sont des bois qui peuvent \u00eatre en contact permanent avec l\u2019eau douce, ces bois sont davantage stabilis\u00e9s, ils sont imputrescibles. Certains le deviennent \u00e0 l\u2019aide d\u2019un traitement, comme le Pin Sylvestre ou bien \u00e0 l\u2019aide d\u2019un processus, comme le bois Fr\u00eane thermo chauff\u00e9. D\u2019autres sont de classe 4 naturellement, c\u2019est le cas de la majorit\u00e9 des bois exotiques.<\/p>

Classe 5<\/span><\/strong>\u00a0: La classe 5 regroupe les essences pouvant \u00eatre en contact permanent avec l\u2019eau sal\u00e9e, ces bois sont tr\u00e8s durables. Les bois exotiques Itauba et Massaranduba font partie des bois de classe 5, ces bois proviennent d\u2019Am\u00e9rique du sud et ont une durabilit\u00e9 de plusieurs d\u00e9cennie.<\/p>

Dans les utilisations courantes, seuls les bois de classe 4 devraient \u00eatre utilis\u00e9s s\u2019il y a r\u00e9tention d\u2019eau douce\u00a0: Les terrasse par exemple. Les bois de classe 3 sont utilis\u00e9s pour les bardages.<\/p>

Classe 4\u00a0: Pin autoclave vert. (doit \u00eatre trait\u00e9 avec un taux d\u2019humidit\u00e9 initial \u00e0 20 %)<\/p>

Classe 3\u00a0: M\u00e9l\u00e8ze, Douglas rouge (sans aubier), Epic\u00e9a autoclav\u00e9s vert et marron, Pin autoclave marron.<\/p>

\u00a0<\/p>

S\u2019il y a une d\u00e9coupe r\u00e9alis\u00e9e sur un bois trait\u00e9, un produit doit \u00eatre appliqu\u00e9 sur la zone de coupe pour garantir la continuit\u00e9 du traitement.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t<\/div>\n\t\t","protected":false},"excerpt":{"rendered":"
