copy of Optima Swiss curtain -55dB max

Optima Swiss curtains -69dB max offer excellent protection against high-frequency electromagnetic waves from windows. Hypoallergenic, washable (metal protected by plastic sheathing).

Available with tiebacks, loops or eyelets.

They protect against waves outside the home that can enter through windows.

The curtain is available with a ruflette or 4 cm diameter matt nickel eyelets.

Choice of dimensions:

The curtain must be 60 cm wider than the width of the window X in order to ensure good coverage around the window, i.e. X + 60 cm. This width must be multiplied by 1.3 so that the curtain has a minimum amount of gathering.

Curtain width = (window width + 60 cm) x 1.3

Curtain height = 2.5 m Width = 1, 2, 3, etc. to be selected from the WIDTH options in the basket.

Fabric description:

A 0.02 millimetre copper metal thread is covered with a silver thread. To prevent any metal emissions into the atmosphere or potential oxidation, this metal thread is completely covered with a polyurethane lacquer. The wire is then 0.024 millimetres thick. This manufacturing process is unique in the world and is covered by a global patent.

This fabric is used by the military and industry in various countries. It is also used for curtain-type screen fabrics, anti-high-frequency canopy/canopy "Faraday cages" during sleep, and for the manufacture of high-frequency protective clothing.

Characteristics:

• Biocompatible. It contains very little metal, thus avoiding any possible poisoning from excessive metal content when the metal oxidises through respiration once the body is inside the Faraday cage. (Metal protected by polyurethane sheath).
