Warm roofs are single-shell roof structures without a rear ventilation level. The waterproofing lies directly on the thermal insulation. Warm roofs are currently the most common type of construction, especially in the flat roof sector, which is technically mature and economical to produce. In addition, warm roofs are thinner in their overall structure.
