Insulating “warm edge” spacer for IG Units, made by glass fibre reinforced polymerInsulating glass units have been manufactured so far using metal spacers, usually in Aluminium.

Due to the extremely high thermal conductivity of Aluminium, an enormous thermal bridge is created along the perimeter of the insulating glazing. Consequences are condensation or possible mould formation around the glass edge, comfort reduction & additional heat loss.By use of thermal insulating spacers (so-called: “warm edge“), the thermal transmission Uw of a total window can be improved and damaging condensation and unhealthy mould formation can be avoided, if normal air ventilation is properly assured.SGG SWISSPACER, a high-tech Product from SAINT-GOBAIN GLASS, consisting in a glass-fibres reinforced Polymer as base material, stands for a completely new generation of IG unit spacers.

Good arguments with SGG SWISSPACER “warm edge”:

Thermal insulation:
-The new international standard for thermal transmission of windows: EN ISO 10077 takes into account for the first time the thermal bridge effect of conventional metallic spacers at the glass edge of insulating glazing
–SGG SWISSPACER is a real „warm edge“-system, providing excellent insulation at the glass edge.
–The new version SGG SWISSPACER V shows till now unbeaten „warm edge“ performances down to y-values of 0.032 W/mK.
–Thermal bridge effect can be reduced by 50-60%, according frame material and type.
–Window Uw value can be improved by 10% or up to 0.3 W/mK
–Can be incorporated in all types of IG units, function of glazing remains unchanged
–Same external geometry as conventional aluminium spacers
–Due to its high mechanical and thermal resistance especially suited for use in roof glazing or curtain-walls facades

–Special glass-fibre reinforced composite for highest demands on mechanical and thermal resistance up to 100°C.
–Extremely thin metal foil guaranteeing both, gas tightness and excellent adhesion for all types of sealants
–Long term established and controlled use of desiccants
–Mechanical characteristics and geometry allow processing in the same way and the same IGU equipment as for conventional aluminium spacers, incl. Georgian bar setting

–A wide choice of colours is available: 2 standard colours and more than 10 special colours
–Solutions for georgian bar construction matching the spacer colour range
–Harmonisation of colours between spacer bar and window frames, gaskets and handle possible
–Noble matt surface, without disturbing metal reflections
–Perfect 90°-corners with SGG SWISSPACER, using corner keys or bending machine

Living comfort and maintenance
–Higher temperatures at the glass edge means higher comfort
–Evidently less condensation risk at the glass edge, and thus moisture problems harmful for health
–Longevity of frames, specially wood frames increase drastically

–Up to 5% less heating costs by improved insulation (with a ridiculous small part on total building envelopes surface) and thus, reduction of CO2 – emission
–Is fully recyclable

–For window manufacturers IG units with SGG SWISSPACER is the easiest and cheapest way to improve the heat transmission Uw of windows and serves as a basis to introduce „warm edge“ step by step
