Roof Type Constructions
Longstrip metal roof constructions have traditionally been categorised into various types:
Cold Roof
In which the principle thermal insulation is placed at or immediately above the ceiling, resulting in the roof covering and structural deck being substantially colder in winter than the interior of the building.
Warm Roof
In which the principle thermal insulation is placed immediately below the roof covering, resulting in the structural deck and ceiling being at a temperature close to that of the interior of the building.
(The design principles of cold and warm roofs with regard to condensation and condensation control is the main difference between the two types.)
Inverted Roofs
In which the principle thermal insulation is placed above the roof covering, resulting in the roof covering structural deck and ceiling being at a temperature close to that of the interior of the building.
Hybrid Roofs
Combining the features of two or more of the roof types described above. Examples include structural decks with high thermal insulating properties combined with additional insulation and existing roofs to which thermal insulation is added.
