Le <strong>parquet flottant<\/strong> s\u00e9duit parce qu'il ne se cloue pas et ne se colle pas au support : les lames reposent sur une sous-couche et sont li\u00e9es entre elles. Cette simplicit\u00e9 a pourtant des limites que l'on d\u00e9couvre souvent trop tard. Voici les cinq questions \u00e0 se poser avant de commander.<\/p>\n<h2>1. Mon sol actuel peut-il rester en place ?<\/h2>\n<p>C'est tout l'int\u00e9r\u00eat de ce type de r\u00e9novation, mais tout d\u00e9pend du support. Une dalle, une chape ou un plancher peuvent convenir, \u00e0 condition d'\u00eatre sains, secs et plans. Le rep\u00e8re du NF DTU 51.11, le texte de r\u00e9f\u00e9rence sur les parquets flottants, tient en deux mesures : <strong>5 mm de tol\u00e9rance sous une r\u00e8gle de 2 m<\/strong>, et 1 mm sous un r\u00e9glet de 20 cm.<\/p>\n<p>Le test se fait en quelques minutes avec une grande r\u00e8gle de ma\u00e7on. Si les creux d\u00e9passent ces valeurs, un ragr\u00e9age s'impose avant la pose. Un ancien carrelage bien scell\u00e9 peut souvent \u00eatre conserv\u00e9, mais la notice du fabricant reste le document qui tranche. Pensez aussi \u00e0 la hauteur gagn\u00e9e : le bas des portes devra parfois \u00eatre rabot\u00e9.<\/p>\n<h2>2. Toutes les pi\u00e8ces sont-elles concern\u00e9es ?<\/h2>\n<p>Non. Le DTU ne couvre pas la pose flottante dans les <strong>locaux humides<\/strong> comme la cuisine ou la salle de bain. Cela ne veut pas dire qu'aucun produit n'y existe, seulement qu'il faut alors s'en remettre aux prescriptions \u00e9crites du fabricant, et v\u00e9rifier que la r\u00e9f\u00e9rence choisie y est bien autoris\u00e9e.<\/p>\n<p>M\u00eame prudence avec un <strong>sol chauffant<\/strong> : ce cas sort lui aussi du champ du DTU sur les parquets flottants. Demandez la confirmation du fabricant avant d'acheter, pas apr\u00e8s.<\/p>\n<h2>3. Quel type de lames choisir ?<\/h2>\n<p>Le DTU vise les parquets contrecoll\u00e9s : une couche d'usure en bois noble sur un support stabilis\u00e9. Le massif pos\u00e9 en flottant n'entre pas dans son p\u00e9rim\u00e8tre. Pour un particulier qui r\u00e9nove, le contrecoll\u00e9 \u00e0 clipser reste donc la piste la plus simple, car les lames s'assemblent sans colle ni clous. Les fiches de <a href=\"https:\/\/www.parquetsprotat.com\/parquets\/parquet-flottant-a-clipser.html\">parquetsprotat.com<\/a> donnent une id\u00e9e concr\u00e8te de ce que cette famille propose, en ch\u00eane notamment.<\/p>\n<p>Comparez ensuite trois points plut\u00f4t que le seul prix : l'\u00e9paisseur de la couche d'usure, qui d\u00e9termine les possibilit\u00e9s de r\u00e9novation futures, la finition (huil\u00e9e ou vernie) et le syst\u00e8me d'assemblage.<\/p>\n<h2>4. Quelle erreur co\u00fbte le plus cher \u00e0 la pose ?<\/h2>\n<p>L'oubli du <strong>jeu de dilatation<\/strong>. Le bois travaille avec la temp\u00e9rature et l'humidit\u00e9, et un parquet flottant bouge d'un seul tenant. Il ne doit donc toucher ni les murs, ni les huisseries, ni les tuyaux de chauffage, ni aucun autre obstacle. La r\u00e8gle : un jeu de 0,15 % de la plus grande dimension, avec un minimum de 8 mm. Pour une pi\u00e8ce de 8 m, cela repr\u00e9sente 12 mm sur le pourtour.<\/p>\n<p>Plinthes et barres de seuil recouvrent cet espace, sans jamais bloquer le parquet. C\u00f4t\u00e9 pr\u00e9paration, pr\u00e9voyez aussi une pi\u00e8ce \u00e0 15 \u00b0C au moins, s\u00e8che et ventil\u00e9e, avec des paquets stock\u00e9s \u00e0 l'abri de l'humidit\u00e9. Une pose r\u00e9alis\u00e9e juste apr\u00e8s des travaux de pl\u00e2tre ou de peinture s'expose \u00e0 des d\u00e9sordres, car le b\u00e2timent doit d'abord avoir s\u00e9ch\u00e9.<\/p>\n<h2>5. \u00c0 quoi s'attendre une fois le sol pos\u00e9 ?<\/h2>\n<p>Une pose flottante ne donne pas la m\u00eame sensation qu'un parquet clou\u00e9. Une <strong>l\u00e9g\u00e8re souplesse<\/strong> et quelques petits grincements \u00e0 la marche font partie de sa nature, et ne signalent pas forc\u00e9ment une mauvaise pose. Si ce ressenti vous g\u00eane, testez un \u00e9chantillon pos\u00e9 en situation r\u00e9elle, ou essayez une sous-couche plus adapt\u00e9e \u00e0 votre support.<\/p>\n<p>En contrepartie, le chantier reste court et peu salissant, et la pi\u00e8ce redevient vite utilisable. C'est souvent ce qui d\u00e9cide : on change l'ambiance d'un logement habit\u00e9 sans le vider plusieurs semaines. Mesurer le support, v\u00e9rifier la pi\u00e8ce, calculer le jeu : ces trois gestes, faits avant la commande, \u00e9vitent l'essentiel des mauvaises surprises.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Support, pi\u00e8ces concern\u00e9es, type de lames, jeu de dilatation, ressenti \u00e0 la marche : les cinq questions \u00e0 se poser avant de commander un parquet flottant.<\/p>\n","protected":false},"author":1,"featured_media":929,"comment_status":"closed","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[1],"tags":[],"class_list":["post-930","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-construction-renovation"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.3 -
