Where extending above a roof a parapet may simply be the portion of an exterior wall that continues above the line of the roof surface or may be a continuation of a vertical feature beneath the roof such as a fire wall.

Thermoblock thermal break blocks reduce heat loss in parapet applications making insulation at the roof to wall transition continuous and the roof more energy efficient. Roof pitch because parapet roofs are encircled by walls they are more prone to leaking than traditional pitched roofs. Tbm 1 and tbm 2 structural thermal break materials reduce heat loss in steel and aluminum connections that penetrate the roof thermal envelope. Like any roof with batt insulation the venting is an important part of the system.

The outside of the parapet wall will have a similar finish to the rest of the exterior walls. Traditional tiles are made from terracotta clay but there are also ceramic tiles roofs made of fired clay as well as concrete tile roofs.
