SGG PLANITHERM® ONE: thermal insulation glazing


SGG PLANITHERM ONE represents the most advanced thermal insulation performance within the SGG PLANITHERM family. It offers the lowest possible centre pane U-value available from a double or triple glazed unit in the UK today.

SGG PLANITHERM ONE offers excellent thermal insulation properties in combination with high neutrality. It is an ideal solution for both commercial applications (refurbishment and new build) and domestic new build applications.

• Façades / windows
• Curtain walling
• Structural glazing
• Overhead glazing

• Windows and skylights
• Patio doors, bi-fold doors, French doors and other external doors

• Exceptional thermal insulation performance through very low centre pane u-values (1.0W/m2K in double glazed format and 0.5W/m2K in triple glazed format) while retaining advanced neutral aesthetics.
• Using sealed units with SGG PLANITHERM ONE inside virtually guarantees compliance to the UK Building Regulations in terms of helping windows and facades achieve low whole window U-values.
• Considerable reductions in heating bills and eliminates cold areas around windows.
• Significantly reduced condensation on the inner pane.
• Maximises the transmission of natural light into the building, especially when compared with other low-e glasses.
