INSULATING GLASS PACKETS

Glass packets with selective glazing reduces the heat loss of the building, resulting in savings on heating costs. The tint of the glass packet is neutral with minimal reflection. At the same time, natural daylight flows in through the selective glass, reducing the need for artificial lighting.

The thermal transmittance coefficient U of the glass packet depends on the type of selective coating, the number of chambers in the glass packet (single or double chamber), the inter-profile width, the type of gas filling (argon or krypton).
