Frequently Asked Questions

What is the difference between PUF and PIR panels, and which should I choose?

PUF (Polyurethane Foam) panels offer excellent thermal insulation and are cost-effective for general applications. PIR (Polyisocyanurate) panels provide superior fire resistance with Class B1 rating and better high-temperature performance. Choose PIR for applications requiring enhanced fire safety, clean rooms, or high-temperature environments. PUF is ideal for standard industrial and commercial buildings where cost optimization is important.

How do I calculate the right panel thickness for my thermal requirements?

Panel thickness selection depends on required U-value, climate zone, and application. Our thermal engineering team provides free calculations considering indoor/outdoor design temperatures, humidity levels, and energy efficiency targets. Generally, 100mm provides U-value ~0.23 W/m²K, 150mm achieves ~0.16 W/m²K. We offer thermal modeling services to optimize thickness for your specific project requirements.

What quality control measures ensure consistent thermal performance?

Our ISO 9001:2015 certified process includes continuous monitoring of foam density, thermal conductivity testing per ASTM C518, cell structure analysis, and dimensional accuracy verification. Each production batch undergoes thermal conductivity testing, compression strength testing, and fire performance validation. We maintain detailed quality records and provide thermal performance certificates with each shipment.

How do the panels perform in extreme weather conditions and high humidity?

Our panels are designed for diverse climatic conditions with closed-cell foam structure preventing moisture absorption. Galvanized or color-coated steel facings provide weather protection. PIR cores perform continuously up to +120°C, PUF cores up to +80°C. Integrated vapor barriers prevent condensation issues. Special coatings and joint systems are available for coastal, industrial, or high-humidity environments.

What installation training and technical support do you provide?

We offer comprehensive installation training including hands-on workshops, thermal bridging prevention techniques, and quality control protocols. Our technical team provides site supervision for critical projects, thermal imaging verification, and troubleshooting support. Training covers proper handling, joint sealing, fastening procedures, and and performance testing methods.

Are custom panel sizes and special configurations available?

Yes, we manufacture custom panel lengths up to 16 meters, special thicknesses, and non-standard widths based on project requirements. Custom edge profiles, integrated accessories, and special facings (stainless steel, aluminum) are available. Fire-rated configurations, enhanced structural panels, and specialized foam formulations can be provided with appropriate minimum order quantities.

How do I ensure compliance with green building and energy codes?

Our panels contribute to LEED points through energy efficiency, low VOC emissions, and recyclable steel content. We provide thermal performance documentation, energy modeling support, and building code compliance verification. Our technical team assists with green building submissions and provides necessary documentation for Energy Conservation Building Code (ECBC) compliance.

What maintenance is required and what is the expected lifespan?

Panels require minimal maintenance with periodic inspection of joint seals and protective coatings. Expected lifespan is 25-30 years with proper installation and maintenance. Thermal performance degradation is less than 5% over 25 years. We provide maintenance guidelines, inspection checklists, and repair procedures. Protective coatings may require renewal every 10-15 years depending on environmental exposure.
