At Modular Framing Systems, we offer more than just modular framing — we provide high-performance solutions for climate control, soundproofing, and structural stability. Our P3isomac galvanized panels are built to meet the needs of industrial and commercial environments, and are now available in two thickness options: 25mm and 45mm.
With a water-foam injected polyurethane core and double galvanized steel sheathing, these panels combine strength, insulation, and durability in one package.
🔹 Key Features of Both Panels
- Superior Thermal Efficiency:
Engineered with polyurethane insulation, each panel offers an initial thermal conductivity of 0.024 W/(m·°C) for excellent energy performance. - Double Galvanized Steel Sheathing:
Both sides are protected with 0.5 mm galvanized steel, one side pre-varnished white-gray (similar to RAL 9002), offering corrosion resistance and clean aesthetics. - Safe & Eco-Conscious:
Polyurethane foam is water-expanded — contains no HCF, CFC, or HFC. - High Soundproofing Performance:
Sound reduction rating of Rw 40 dB (ISO 140/10), making it ideal for noise-sensitive applications. - Wide Temperature Range:
Suitable for use from –40 °C to +80 °C (–40 °F to +176 °F), maintaining performance in extreme conditions.

How to Install Panels and Skin a Unit
Start Here — Step 3: compare Standard and Stopper panel installation, plan gaskets and clearances, and understand common sheet-metal skinning techniques.

How do I size panels and account for the appropriate clearances?
** The standard production tolerance on panels is +/- 1/16in. For fixed panels, most customers allow for a 1/16in reduction in size from the panel opening. When considering production tolerances
