Artist: Unknown
Medium: oil on paper
Passive system designed to stabilize humidity within the frame. Prevents cockling buckling, expansion and contraction of the art. Waterproof and prevents mold growth.
Originally designed for The National Gallery of Art, this system has proven itself through hurricanes on both paintings and works on paper. An excellent solution for delicate works subject to transit and exhibition.
The glazing (glass) will filter 99.9% of UV (ultraviolet) light, and is layered, so that in the event of breakage, it will not damage the work of art.
Testing indicates a useful lifespan of 30 +/- years.
It is frequently used on yachts, for works in bathrooms and other high humidity situations
