How Secondary Glazing Makes Sense for Sash Windows

Safer Windows Start with Double Panes
Many properties still have thin glass sash windows that lack strength. The sealed unit in double glazing makes it harder to smash. New sash windows come with built-in protection.
Cut Down on Outside Disruption
If your property is near a school, you’ll likely be affected by regular outside noise. With updated windows, sound from outside becomes much less of a problem. You’ll find it easier to relax without background noise getting in the way.
Stronger Energy Efficiency
Less warmth is lost through glass that’s been double glazed. This means less energy is needed, so your home stays warm for less.
Smart Improvements That Work for Historic and Listed Buildings
Period homes can come with limits on altering the exterior. You can often install new glazing that won’t change the outside appearance. Speak to your heritage contact to find out what’s allowed.

Well-Made Units That Stay in Top Condition
Double-pane units are made to hold up well. When made with quality in mind, these windows last well. It’s one of those upgrades that makes life easier well into the future.
