Installation of windows without the need to dismantle the old door frames

Renovation frame systems are used for the installation of windows without the need to dismantle the old door frames, this type of mass windows is used in some European markets, since then in France and Italy. The characteristic masking profile covers the old door frame forming a kind of band from the inside, while from the outside you can use special casing profiles that allow you to eliminate part of the “dirty” finishing work.
In the Aluplast Ideal 4000 renovation system, we make windows with masking profiles with heights of 40mm and 65mm.
