The proven Swiss Original with extra "flex"

Swisspacer UTLIMATE PRO focuses on optimal processing of the spacer bars and maximum safety for their function in the insulating glass unit. Thanks to the sophisticated material composition of ABS and glass fibres, ULTIMATE PRO can be processed with a high degree of elasticity – and at the same time ensures that the spacer bar frame has the required stability. ULTIMATE PRO can be processed particularly efficiently and safely transported within the production facility. Cycle times can therefore be further optimised, while rejects in the production process are reduced to a minimum. The optimally coordinated design of geometry, perforation and film also delivers maximum certainty about the functionality of the insulating glass units, in particular as regards the lifespan.

The proven properties of the Swisspacer warm edge can obviously be relied on: ULTIMATE PRO has a particularly low thermal conductivity. The representative Psi values and the Uw values for windows and façades were determined in accordance with the recognised ift guidelines WA-17/1 & WA-08/3. And the look also impresses: ULTIMATE PRO offers an excellent look with a matt surface that avoids reflections.
