ProfHolod is pleased to inform its partners and customers about the extension of validity periods for compliance certificates on the following products:
- fire‑resistant doors of the OD P, RDOP P, and RDD P types;
- sandwich panels with rigid covers and polyurethane foam (PUF) insulation (SIP Panels (PUR)).
The company systematically ensures that all permitting documentation remains up to date and guarantees that its products fully comply with current technical regulations and industry standards. The certificate extensions confirm that the products retain their declared performance characteristics and meet all applicable safety requirements. This is crucial for design solutions, passing expert reviews, and facility acceptance.

Products covered by the extended certificates:
1. Fire‑resistant doors (types OD P, RDOP P, RDD P) — structures designed for installation in fire barriers, providing the required fire resistance time. These products meet fire safety requirements for public, industrial, and warehouse buildings.
2. Sandwich panels with rigid covers and PUF insulation (SIP Panels (PUR)) — a solution for facilities with high requirements for structural rigidity and energy efficiency. The rigid covers ensure panel geometry stability during both installation and long‑term operation.
The extension of the certificates allows our partners to confidently include these items in design and cost estimation documentation, as well as to plan procurements without the risk of supply disruptions due to expired permitting documents.
