- A3: Installations conform to EN 1363 (fire barrier), ANSI FM 2810, and local building code annexes regarding anchoring, joint treatment, and access openings.
- Q4: How do you measure corrosion resistance?
- A4: Salt fog (ASTM B117), acid vapor (ISO 3231), and H2S exposure tests are conducted; superior Explosion proof wall maintain ≥ 1000h resistance to ensure fitness for harsh industrial and marine atmospheres.
- Q5: What are the common thickness specs?
- A5: Standard panels range from 60mm to 200mm depending on blast load design; custom double-skin or composite pads can be engineered for up to 300mm in high-risk environments.
- Q6: Does the product offer acoustic/fire resistance?
- A6: Yes. Integrated high-density mineral wool or composite cores deliver ≥ 42 dB acoustic isolation (EN 10140), and inner layers can be specified for up to 180 min. fire integrity (UL 1709, EN 1363-1).
