Are you unable to install double glazing in your window frames, but still want a well-insulated house? Then the secondary glazing from Glashandel Sloos is an ideal and more affordable solution!
A secondary window is an extra pane that we mount in front of or behind your current window. Thanks to the rubber seal, heat and sound are effectively insulated. Do you currently have single glazing? By using secondary glazing, you can easily achieve the same effect as double glazing.
