Swisspacer ULTIMATE ensures impressively low thermal conductivity at the edge of the insulating glass unit and, according to internationally acknowledged guidelines, is one of the best warm edge spacer bars in the world. This ensures correspondingly low Uw values for windows and facades, together with energy savings for users. The warm edge avoids the formation of condensation and mitigates the risk of mould, thus contributing to much improved living comfort. Swisspacer also saves CO2 and therefore supports the sustainable construction of windows and facades. 

Not to mention how Swisspacer also impresses in terms of its technology and looks: The high stability of the hollow profiles ensures an exceptional parallelism of the frame while the film provides many years of functionality and a long service life. The matt surface avoids reflections; thanks to the scope of supply including 17 different colours, the insulating glass unit can adapt to the appearance of any window.

Key performance indicators

For a quick comparison, the Psi values for Swisspacer ADVANCE and ULTIMATE are shown here for different window constructions, as are comparative values for conventional spacer bars. CALUWIN enables exact calculations of the Uw values and offers many other functions.

The energy-saving calculator

CALUWIN is an online tool for determining the Uw values for a wide range of different window constructions for architects and engineers as well as planners and consultants. Energy savings and condensation levels can also be precisely calculated and compared. Finally, the tool also supplies data on CO2 emissions.
