Exterior sun-shading of windows using Warema's Standard External Venetian Blinds reduces the heating effects of solar radiation by up to 90% to create relaxing, comfortable interior spaces. Unlike textile blinds external venetians can admit reflected light resulting in light-filled working or living spaces and reducing the need for artificial lighting throughout the day. Through tilted venetian slats an external view and connection to the exterior is maintained on demand whilst privacy is preserved.

For the highest class of finish, longevity and performance Warema offers the Premium Slat External Venetian Blind. The slat profile is extremely rigid and features only a slight curvature resulting in almost unhindered viewing. The finish is an innovative new direction from Warema offering a natural anodised rather than coated surface. Anodising hardens the slat surface protecting it for a prolonged period. Anodising is a finely textured and gently reflective finish with excellent solar protection properties. The anodised finish matches the surface of commercial and residential glazing systems achieving a perfect synthesis of façade elements. Wind performance exceeds all other systems, with a threshold of up to 30 metres per second (108 km/h), subject to installation configuration.

Warema external venetian blinds with Provisio technology not only provide heat protection and glare control but also improved visual privacy.  ProVisio Technology can improve the view out based on the changing inclination throughout the entire length of the slat that is designed to mimic the human angle of sight.  This ensures the best view out through the slats at eye level while maintaining total privacy from the outside looking in.
