Our Budget canopies are made with shielding materials that are produced outside Europe. The shielding is high and the fabric has been tested and approved. The sizes are fixed. Customisation is not possible. However, discolouration may occur due to the oxidation of the silver. Discolouration may already have occurred during transport of the rolls before the canopies have been made. If you do not want this or you do not find this acceptable, choose our Luxe canopies (Swiss Shield fabric does not discolour). The budget canopy is a cheaper alternative to create a Faraday cage and protect yourself against radiation.
