Fenestral installs silica gel in all double-glazed energy-efficient panes to prevent moisture between the glass. The silica gel absorbs moisture, thus preventing its appearance.
Additionally, all energy-efficient glazing installed in Fenestral’s aluminum frames undergoes double sealing with Butyl and polysulfide sealant. This ensures better performance against temperature changes (cold – heat) and prevents moisture between the panes.
Specifically, the double bonding – sealing of energy-efficient glazing (hot and cold) offers significantly better performance against temperature changes (both cold and heat).
