Pre-Engineered Industrial Steel Structure Workshop Roof & Wall Insulation

Project Background

Modern pre-engineered steel buildings require advanced thermal envelopes. This case study details the thermal and acoustic insulation installation for a massive manufacturing plant built completely with a steel frame structure, covering a total roof and wall surface area of over 45,000 square meters.

The Challenge

• The “Oven Effect”: Uninsulated steel structures absorb immense solar radiation in summer, turning the interior into a high-temperature zone, which hinders manufacturing labor.
• Condensation on Steel Sheets: Thermal bridging on metal panels during winter causes condensation, leading to interior rain effects, destroying machinery, and accelerating rust.
• Industrial Noise Transmission: Heavy rain impacts on large metal roofs create loud interior noise levels that disrupt industrial operations.

Our Solution

We supplied high-performance Glass Wool Blankets with Factory-Applied FSK Facing designed specifically for roll-out application over steel purlins.

• Superior Thermal Barrier: The glass wool matrix acts as a powerful buffer against solar radiant heat transfer, keeping the workshop interior significantly cooler.
• Integrated Vapor Barrier (FSK Facing): The reinforced aluminum foil facing provides a seamless, tough moisture-vapor barrier, stopping indoor humid air from touching the cold outer metal sheets.
• Excellent Sound Absorption: The soft, fibrous network of the glass wool blankets absorbs the mechanical kinetic energy of rain impacts, deadening noise transfer.

The Result

• Substantial HVAC Cost Efficiency: The workshop achieved an energy-saving rate of over 18% on seasonal indoor cooling and heating operations.
• 100% Elimination of Condensation: The internal steel roof remained completely dry throughout winter, ensuring zero water damage to high-precision CNC machinery below.
• Enhanced Acoustics: Indoor noise levels during heavy rainfall dropped by over 20 dB, creating a compliant and productive working environment for factory workers.
