BENGglas Extra Clear is the clearest vacuum glass in the range. Almost as transparent as single glazing, yet with an insulation value of U=0.50. This means more natural daylight, free solar heat, and lower heating costs.
And the best part? It fits perfectly into existing frames. Ideal for heritage buildings: the original appearance is preserved while comfort is significantly improved.
