From FogQuest
"FogQuest purchases the mesh that we use in Chile from a company called Marienberg. We do this because the price is reasonable, the company produces the mesh in 8 meter widths and very long lengths, and many of our applications are in Latin America.
The contact information to order 35% shade coefficient Raschel mesh is:
Jorge Kleiman, Export Director
Cia. de Mallas y Plasticos
Industrial y Comercial Marienberg Ltda.
Email:
jkg@marienberg.cl. Telephone: (56-2) 689 8031
We do not know of a suitable supplier in the United States or Canada. However, if you know of one that produces 35% shade coefficient, Raschel weave, u.v. protected polypropylene or polyethylene mesh, in large sizes, please let us know at
info@fogquest.org. Tildenet in the United Kingdom used to make the mesh but we do not believe it is available from them now.
Other sources of the mesh have had some problems of quality and durability.
Note: we use the 35% Raschel mesh in a double layer. This is important to maximize the fog collection efficiency.
The particular fiber width (about 1 mm) and the specific Raschel weave are both also important in order for the collection process to be efficient.
It is not possible to put up any type of plastic mesh, metal screen, imaginative three-dimensional structure, or whatever, and expect to collect large amounts of fog water.
You can see pictures of the double layer of mesh on our homepage. For copies of scientific publications discussing these issues, please write to
info@fogquest.org."
