SHEETSINSULATION CORK SHEETS

Duplas Inc., our country's first and only cork processing company, has processed the marvel of nature, cork, with high technology to offer DUCORK RLU - IML, a high-performance sound and thermal insulation material, for use in the construction sector. The 100% natural nature of DUCORK RLU - IML and its lack of carcinogenic content have been proven through tests. The product shows an 88% recovery rate at 50% compression and is much more resistant to chemicals compared to other insulation materials. DUCORK RLU - IML simultaneously provides both thermal and sound insulation, highlighting its difference from other insulation materials. Thanks to this feature, it does not require any additional products, significantly reducing costs. It demonstrates high performance in preventing footstep sounds and cold from the ground in floor coverings. It is resistant to moisture and mold. It does not harbor bacteria, insects, fungi, or similar organisms. Its flexible structure absorbs impacts, preventing permanent deformations. Its lifespan is equivalent to the lifespan of the building.
