Vapor-permeable foils are used in ventilated roofs and facades and allow the passage of water vapor from thermal insulation. This reduces the possibility of moisture condensation.
Vapor-permeable foils are used in ventilated roofs and facades and allow the passage of water vapor from thermal insulation. This reduces the possibility of moisture condensation. The water vapor permeability of the foil is important, which is indicated by the SD factor and should be as low as possible. Films that have a SD in the range of 0.02m and 0.2m are usually considered to be vapor-permeable films. At the same time, vapor-permeable roof foils also act as a secondary covering or for facades as a wind (air) barrier. We offer vapor-permeable foils with different mechanical properties and vapor permeability, namely:
Metrapan Classic vapor permeable film with a 130g thick membrane can withstand high loads and is suitable for roofs that condense heavily. High UV resistance and strong structure ensure long durability and service life regardless of weather conditions.
Usage:
for roofs that condense heavily
for insulating, ventilated and pitched roofs
for all types of roofs, especially for concrete, ceramic and metal roofs
suitable for attic renovations, not just new construction
Advantages:
minimal heat loss
regulates bilateral vapor permeability
very durable and resistant to damage
three-layer film resistant to weather conditions and aging processes
