With increasingly hot summers, air conditioning or modern window covers are becoming a necessity in modern construction. Traditional interior blinds stop solar radiation only inside the room, which does not prevent it from heating up. A real barrier to the sun is provided by covers mounted on the outside. Before purchasing, investors face a dilemma: should they choose external roller shutters or external venetian blinds?
External Roller Shutters – Maximum Thermal Insulation and Privacy
External roller shutters are made of aluminum slats filled with polyurethane foam. When lowered, they form a solid armored barrier in front of the window. This provides excellent heat protection in summer, but also additional thermal insulation in winter, which reduces heat loss. Roller shutters guarantee complete blackout of the room (ideal for bedrooms) and act as an excellent acoustic barrier, dampening street noise.
External Venetian Blinds – Precise Light Control and Modern Design
External venetian blinds (facade blinds) consist of movable, flat slats in a C or Z shape. Their biggest advantage over roller shutters is the ability to smoothly adjust the angle of the slats. Thanks to this, you can precisely control the amount of light entering the interior without having to fully darken the living room. External blinds look exceptionally light and modern, fitting perfectly into luxurious, minimalist architectural designs.
Verdict: What to Choose for Your Home?
The choice depends on the purpose of the rooms. External roller shutters work great in bedrooms, children's rooms, and on the ground floor, where we want maximum privacy, silence, and darkness. On the other hand, external venetian blinds are the ideal solution for the living area and a lounge with large glazing, where you want to freely regulate the influx of light during the day. In the AM Okna offer, you will find both systems, which we will match perfectly to your needs and the building's facade.
