Wat is het verschil tussen HR++ en standaard dubbelglas?

Standaard dubbelglas is twee ruiten zonder coating. HR++ (hoogrendementsglas) heeft een onzichtbare low-e coating en argonvulling in de spouw, waardoor het veel beter isoleert — een aanzienlijk lagere U-waarde en dus lagere stookkosten.

Wat betekent de U-waarde?

De U-waarde geeft aan hoeveel warmte er door het glas verloren gaat: hoe lager, hoe beter de isolatie. Onze configurator toont de U-waarde uit de leverancierstabel, die meebeweegt met de gekozen uitvoering en spouwbreedte.

Welke spouwbreedte kan ik het beste kiezen?

Een bredere spouw isoleert beter, tot ongeveer 16 mm; daarna neemt de winst weer licht af door luchtstroming in de spouw. 15–16 mm is doorgaans de beste keuze voor HR++.

Kan ik gelaagd, mat of zonwerend glas combineren?

Ja — je kiest per ruit (buiten en binnen) de dikte en de uitvoering (blank, mat, gelaagd/veiligheid, figuur, geluidwerend). Zonwerend glas (Klima) kies je via de uitvoering SUN.

Is isolatieglas op maat retourneerbaar?

Nee, isolatieglas wordt op jouw exacte maat gemaakt en is maatwerk — daarom is het van herroeping uitgesloten. We maken het op de millimeter op maat en leveren verzekerd.

Warm Edge TGI or silicone sealant — which should I choose?

Warm Edge TGI (black): The TGI® Spacer is a thermally broken spacer that reduces heat loss at the edge of the insulating glass and improves the insulation value of the whole window (glass + frame). Less of a cold bridge along the edge also means less risk of condensation in the edge zone.

UV-resistant silicone sealant (black): Silicone edge sealant (UV-resistant) is a special black sealant edge that withstands ultraviolet light. Needed for panes whose edge is exposed to sun and moisture — skylights, garden rooms, boat windows — and for any pane that is not covered all round by beads or profiles. If the pane sits behind glazing beads all round, it adds nothing.
