Low-e glass panel PLANITHERM® XN

insulatingthermal insulatinglaminated

Product description
PLANITHERM® XN (II) is Saint-Gobain Glass reference low-emissivity (low-e) glass for insulating glass units (IGUs), primarily for windows and for commercial refrigeration doors. It is produced from clear glass (PLANICLEAR®) with a thin silver-based transparent coating deposited by magnetron sputtering under vacuum. The coating reflects far-infrared radiation and reduces heat loss through glazing, offering improved thermal performance versus non-coated double glazing.

Benefits & applications

• Suitable for IGUs in new construction and renovation for residential and non-residential windows and façades.
• Used in commercial refrigeration glass doors to maintain insulation and transparency under temperature differentials.
• EASYPRO® temporary surface protection available on demand for to-be-tempered coated glass to prevent mechanical damage during storage and processing; it burns off during tempering without residue.

Table: PLANITHERM® for glass door of refrigerated cabinet
Use: Glass doors of refrigerated display cabinets
Context: Retail shops and supermarkets with large internal cabinet-to-ambient temperature differentials
Advantages: Improved insulation and high transparency when assembled in double or triple glazing units; reduces energy consumption of refrigeration cabinets and lowers operating costs

Appearance
PLANITHERM® XN (II) is among the most neutral and highly transparent coated glasses available. Other coatings in the product family (for example ECLAZ® variants) may provide higher light transmission or different aesthetic performance.
