Are you going to swap windows or build a new house and do not know what aperture is best? We will gladly recommend our outdoor blinds. We produce them from aluminum, which makes them very strong and resistant to external influences, especially against sunlight, which often causes color fading. Our outdoor blinds are colour-stable, so you don't have to worry about changing them.
You must have met the blinds inside the room. The window was harder to wash because of the blinds hanging at the top of the windowpanes. Our outdoor blinds are installed outside the window or door and therefore there is no risk that the glass will be harder to wash.
Our outdoor blinds are not only great curtains, but also heat-insulated, so you will save both heating and air conditioning costs. You won't find a better aperture, there's nothing that could be reproach. You will surely be very pleased with the purchase and professional installation.
