The type of forced ventilation most commonly used today is the ” system to tunnel ” which is conceptually the same as that used for poultry confinement , is applied in structures lightweight roof, that is to say metal or wooden structures lightweight braces economic wood but with low distortion, pre – painted ceiling of minimum thickness , ceiling with veneer or PVC (low cost ) , thermal insulation ventilated ceiling with projected cellulose sheet ( recycled material , fireproof , etc.)These systems are suitable for extreme climate regions either in summer than in winter,
