Project Overview

Rinac’s FM approved Firearmet sandwich panels are engineered with state-of-the-art and environment-friendly foaming technology for superior insulation and fire resistance properties using Elastopir. Made of CFC-free rigid polyisocyanurate foaming material (an average density of 42 kg/m3) sandwiched between metal surfaces, these panels help build constructions that are safe, energy-efficient, and have high-temperature stability.

Rinac’s FM approved Firearmet sandwich panels are cost-effective, sturdy, easy to maintain and construct, as well as have high-temperature insulation properties. These find successful applications in the construction of external walls, partition walls, ceilings, and roofs of buildings as well as walls, ceilings, and floors of cold storage infrastructure.

Application of Firearmet

External walls, Partition walls and Ceiling

Roofing

Ceiling and Floor insulation for cold storages, including Blast/Quick freezer application

Salient Features

Lamination of pre-painted galvanized steel (PPGS), stainless steel (SS), or a combination of both with a thickness of 0.5 mm
Fast and easy installation with durable joint systems
Fire-rated core insulation
Perfect moisture barrier due to closed cell structure
Energy-efficient and significantly reduces CO₂ emissions
FM approval class 4880, 4881, and 4471
Quality controlled manufacturing as per the ISO and EN 14509 standards

Benefits of Firearmet
