Cosyseal provides secondary glazing to homes. Popular alternative to ripping out old windows of listed buildings, secondary glazing refers to a lightweight aluminium window that sits inside the property’s existing window, matching the benefits of typical double glazing practices.
The result is a safe and unobtrusive method of implementing modern soundproofing, security, and insulation levels in areas that have restrictions on traditional window replacement.
Authentic sightlines will be successfully maintained and opening sections will match those of the original windows to never impede on easy access.
