Stawiamy na rozwój!
WWGLASS posiada automatyczne linie do zespalania szyb jedno i dwukomorowych. Wdrożenie nowej technologii produkcji niskoemisyjnych szyb dwukomorowych jest nieuchronną perspektywą dalszego rozwoju rynku szyb zespolonych, których technologiczne zaawansowanie na rynku maszyn jest najwyższe i gwarantuje długotrwałą eksploatację bez zmiany parametrów jakościowych wyrobu finalnego.
Production
Key process elements
Insulating glass technology relies on controlled stages: from glass and spacer bar, through cavity fill, to sealing and finished unit inspection.
Spacer bar
The spacer maintains the correct gap between panes and affects edge thermal performance — aluminium or warm-edge, as ordered.
Cavity fill
The inter-pane space can be filled with air or argon, depending on unit build-up and requirements in the specification.
Unit sealing
A primary and secondary seal ensures airtightness — polyurethane or UV silicone, depending on application and edge exposure.
Assembly and stabilisation
Panes, spacer, gas and seal form the finished unit. Dimensional precision, surface cleanliness and process repeatability matter.
Quality control
We verify compliance with the specification, seal quality, format and unit integrity before release from production.

Stress caused by temperature differences in the glass pane — when risk increases and how we mitigate it in production.
Read moreAnisotropy
Characteristic dark spots and streaks visible on tempered glass through polarised lenses or in photographs — an optical effect, not a glass defect.
Read moreGlass deflection
A slight bowing of the pane in a sealed unit caused by temperature and atmospheric pressure changes — when it is normal and when it needs compensating.
