La controverse sur les isolants minces r\u00e9fl\u00e9chissants n’en finit pas. Alors que l’avis technique du CSTB indique que ces produits ne r\u00e9pondent pas aux niveaux r\u00e9glementaires et qu’ils ne constitueraient qu’un compl\u00e9ment d’isolation, Le SFIRMM (Syndicat des fabricants d’isolants r\u00e9flecteurs minces multicouches) conteste le syst\u00e8me de mesure et lance ses propres tests. Cr\u00e9\u00e9 en juin 2006, et regroupant Actis, ATI Isolation, ITR et Valtech Industrie, le syndicat vient de pr\u00e9senter les r\u00e9sultats de ses tests d’hiver \u00ab\u00a0in situ\u00a0\u00bb. Cette m\u00e9thode d’essai consiste \u00e0 isoler de mani\u00e8re diff\u00e9rente des b\u00e2timents identiques, puis \u00e0 mesurer les consommations d’\u00e9nergie n\u00e9cessaires pour maintenir ces b\u00e2timents \u00e0 une temp\u00e9rature int\u00e9rieure identique et constante. Les r\u00e9sultats pr\u00e9sent\u00e9s par les fabricants indiquent 76 % d’\u00e9conomie d’\u00e9nergie pour le b\u00e2timent isol\u00e9 avec un isolant mince multicouche r\u00e9flecteur g\u00e9n\u00e9rique (25 mm) par rapport au b\u00e2timent non isol\u00e9, et 28 % d’\u00e9conomie d’\u00e9nergie par rapport au b\u00e2timent isol\u00e9 avec de la laine min\u00e9rale (20 cm, R = 5 exposant 1). Les r\u00e9sultats des tests en laboratoire du CSTB montraient une r\u00e9sistance thermique de 3 \u00e0 5 fois plus \u00e9lev\u00e9e pour la laine min\u00e9rale que pour les isolants minces multicouches r\u00e9flecteurs. Selon le syndicat, les m\u00e9thodes actuelles de laboratoire (bo\u00eete chaude gard\u00e9e ou plaque chaude gard\u00e9e) sont discriminatoires. Elles sur\u00e9valueraient la performance thermique des isolants \u00e9pais et sous-\u00e9valueraient celles de leurs produits. Dans le cadre de la demande d’Agr\u00e9ment technique europ\u00e9en en cours d’instruction par l’EOTA (European Organisation for Technical Approval), le SFIRMM a pr\u00e9vu de communiquer ces r\u00e9sultats aux membres de l’EOTA et de proposer un programme de recherche au niveau europ\u00e9en par des laboratoires reconnus. Un syndicat europ\u00e9en devrait \u00eatre cr\u00e9\u00e9 le 4 avril 2007 \u00e0 Bruxelles avec un budget global de 900 000 \u20ac.\u000bwww.sfirmm.org<\/span><\/a><\/p>\n","protected":false},"excerpt":{"rendered":"
