No ventilation is required for these types.
Warm roof deck sandwich roof warm roof systems benefit from the insulation sitting above the deck.
Throughout the course of the year the roof deck and all below it is kept at a temperature close to that of the inside of the building therefore the roof structure is protected from extremes of hot and cold lessening the potential for damage caused by thermal movement.
This usually keeps the deck warm.
Alternatively it can be positioned between the rafters or partially between and below the rafter.
The insulation is tapered to provide a fall to the roof to enable water to run to the water outlets.
