Metal roofing and ventilated roofing
Metal roofing and ventilated roofing require a certain organisation of components in order to achieve an upward motion of the air below the final roof covering.
Theoretically, the freshest air comes from outside and escapes from the ridge once it has reduced the heat inside. All of which contributes to better summertime operation of the thermal insulation of the whole roofing system and, finally, to improved energy savings.
For metal roofing and ventilated roofing it is fundamental to have a capable company and workers with the necessary experience, technical skill and good working practices. Hedar has been operating in the industry since 1965 and is part of a pool of specialised and coordinated companies that operate in design and technical assistance as well as providing a site service for supply, setup and installation.
Operating all over the world, with orders secured directly and indirectly, Hedar can claim many highly complicated and prestigious achievements.
Hedar guarantees its clients and designers highly technical and innovative services.
Metal roofing and ventilated roofing: technical aspects
Metal roofing and ventilated roofing must either be in a free and ventilated attic space or a suitable cavity along the pitch of the roof. It must be ensured that this cavity has an adequate section for the entrance of air on the roofing at the line of the eaves and for the exit at the ridge. This section can be obtained both with continued or discontinued gaps, protected from insects and birds, or fixed openings, limiting obstruction of the section as much as possible. The ridge must be sealed from water and snow blown in by the wind.
In any kind of metal roofing and ventilated roofing a micro-ventilation layer below the cover is essential to avoid damp and the formation of condensation (this micro-ventilation prolongs the life of the system).
Hedar metal roofing and ventilated roofing is architecturally innovative and intelligent, in terms of insulation and energy saving too.
The advantages of this metal roofing and ventilated roofing technology include durability, ease of transport, movement and installation.
