Secondary Glazing   For those historic properties that already possess an architectural beauty, changing the windows is not always possible. Clarico understand that older windows were not too good at keeping warmth in and the cold out, but our secondary glazing will allow you to eradicate these issues whilst still retaining the external look of the property! This perfect solution works by trapping air between the existing window and the new secondary window, which in essence acts as a form of double-glazing to provide warmth and insulation. Our secondary glazing is always custom made to compliment and fit perfectly inside your existing windows in a way that keeps them unobtrusive on the inside yet discreet from the outside.
