Description and Features
This system is also called renewal, is designed to allow the installation of a shutter when we have a window without blinds and do not want to work, or just do not want to remove the window.
The drawer is not above the woodwork, but was installed on the outside, in front of the window or on the facade, easily and with little need for work. To get the drawer out of the window, no thermal transfer possible also economizing energy expenditure. They can be aluminum or UPVC.
