-The ducts built with PIR-ALU pre-isolated aluminum panels resists very high levels of pressure, so positive as negative: ·PIR-ALU 20/35 (20mm): <1.000 Pa ·PIR-ALU 30/35 (30mm): <1.400 Pa ·PIR-ALU 20/45 (20mm): <1.100 Pa
-Once built, the ducts and pieces acquire a great resistance and rigidity |
-Light, but very resistant -Installed inside the buildings it is not necessary to take any special caution -Installed outside of the buildings they should be protected of the meteorological inclemencies: rain, hail and wind -The protection of the rain and of the hail it is solved easily with the application of a special painting -The protection of the wind is solved with the appropriate supports |
