Two parallel galvanised steel sheets with 30 mm of polyurethane filler ensure:
- Excellent heat and soundproofing performance.
- Recommended for roofing with extreme exposure to sunlight and noise.
- Global heat transmission coefficient of 0.42 kcal/m²/hºC, which is significantly better than the galvanised steel coefficient of 3.85 kcal/m²/hºC.
