Roofing/Barrier films in Roofing


we are working on a research project on new application fields for barrier films. The barrier films are currently used in food packaging, and they are waterproof, gasproof, water vapour proof, etc.

Can you think of any specific fields, where those barrier functions are required in roofing? (i.e. flat roofs?)
Are there any special characteristics that are needed for the films used in roofing?

Thank you for your help, this is really appreciated.
Best wishes,

This is an interesting question. Obviously if this type of film is used in roofing it would have to be UV stable. Additionally it would need to be highly puncture resistant. There would need to be methods in place to make repairs to the film.
We currently see barrier films in place with regard to air barriers that are installed (generally) on the interior of the building, or behind exterior cladding so that their exterior exposure is generally limited.
Interesting research - good luck.

All types of questions with regard to roofing, waterproofing and sheet metal. This includes commercial and residential buildings, along with the various aspects of the construction means and methods, ventilation, steep-slope or low-slope, code requirements, installation errors and other such problems


I started in roofing fabricating and installing sheet metal flashings out of high school for a large commercial contractor. I worked for the same contractor in the office estimating and project managing commercial project for 10 years. I left the construction side of roofing and now work as a roof consultant, which I have been doing for 8-years.
