J’ai utilisé ces plaques Depron pour un projet de rénovation rapide, et j’en suis très satisfaite. Elles sont extrêmement légères, ce qui facilite grandement la manipulation et la pose. La découpe au cutter est simple et précise, même pour des formes personnalisées. Le collage est très facile et adhère bien aux surfaces lisses, ce qui permet une installation rapide sans outils compliqués. Niveau efficacité thermique, mes murs ne sont plus froids et les bruits sont légèrement atténués, ce qui améliore vraiment le confort. Il faut juste faire un peu attention, car ces plaques sont un peu fragiles, surtout aux coins : elles peuvent se trouer facilement au contact des meubles. C’est normal, ce ne sont pas des plaques dures. Pour ma part, je les ai peintes sur un mur et aiposé du papier peint sur un autre, et le résultat est parfait. J’ai suivi les instructions en appliquant une sous-couche avant et après la pose, et tout est nickel. Je recommande vivement ce produit pour une rénovation simple, rapide et efficace !
