In 2014, ADAMIETZ started production of the ARPANEL sandwich panels, the most modern within the Polish market. A fully automated production line was based on the technology developed by a well-known German company – Hennecke. The ARPANEL products were tested and certified by the Instytut Techniki Budowlanej [Institute of Construction Technology], based on the PN-EN 14509 standard applicable in EU. The most significant scope of certification tests regarded especially: determination of thermal insulation coefficients, fire resistance, preparation of bearing capacity plates, and specification of acoustic insulation coefficients. The wide scope of the ARPANEL offer in the field of insulation cores (PUR, PIR and MiWo) provides an opportunity to choose and adjust our products to proper requirements that objects need to meet. Particular test results classify our products in the group of current market leaders.
