Traditional methods for measuring windows Heat Mass Listing have been replaced by a new butyl seal-mass based system.

Heat retaining benefits of our TPS (Thermoplastic Spacer) structure include:

     * No 'cold bridges' in the area of the glass edge
           Glass periphery is considerably warmer in relation to the surface edge when compared to normal insulating glass. (up to 4-6 degrees Celsius)
           No unpleasant 'sweating' in the insulated area
     * Insulation width easily selectable between 6-20 mm
           fits in any window system
           insulating glass overall thickness can be easily retained despite pane thickness changes
     * Does not contain metal
          Flexible structure
          sustainable, the whole glass panel resistant to breakage
     * Allows various specialty glasses to be used in new ways
           patterned and opaque glass surfaces can to used freely
     * The glass insulation U-value (formerly K-value) is greatly improved
     * Tested

     * Guaranteed standard insulating glass.
     * SFS-standardized
