GUTMANN Window Sill Holder RV-TI

System Accessories

The thermally-separated GUTMANN RV-TI window sill holder prevents unnecessary heat loss. Holders must used on window sills with overhangs greater than 150 mm. Since they were normally made of aluminium, the cold was led behind the insulation to the structural masonry. A high loss of heat when one considers that the holders had to be installed at 60 cm intervals.


This intelligent accessory from the standard GUTMANN product range is – as expected – easy to process. Compared with conventional holders, installation does not take any longer. The benefits of the thermally-separated RV-TI window sill holder are essentially obtained in combination with thermally-insulated (ETICS) facades.

  • Effective contribution to thermal insulation
  • Positive change in surface temperature of 60%
  • An advantage in every external Thermal Insulation Composite System (ETICS)
  • Easy installation
