(FR) VERRE NEUTRE A FAIBLE TRANSMITTANCE
Abstract: front page image
(EN)A neutral, generally green-gray low transmittance (no more than 25 luminous transmittance) soda-lime-silica glass has reduced solar energy transmittance when provided with the following colorant constituents in percent by weight: Fe¿2?O¿3? (total iron) 1.3 - 2; NiO 0.01 - 0.05; CoO 0.02 - 0.04; Se 0.0002 - 0.003. The glass has a ferrous value in the range of 18 to 30.
(FR)Verre silico-sodo-calcique neutre généralement gris-vert, à faible transmittance (transmittance lumineuse inférieure à 25), présentant une faible transmittance pour l'énergie solaire lorsqu'on lui incorpore les colorants suivants (% en poids): Fe¿2? (fer total) 1,3 - 2; NiO 0,01 - 0,05; CoO 0,02 - 0,04; Se 0,0002-0,003. Le pourcentage ferreux du verre est compris entre 18 et 30.
