Internorm external blinds combine climate control with architectural elegance. They provide summer shading while enhancing thermal insulation in winter, redefining comfort and energy efficiency year-round.

Internorm external blinds represent the intelligent boundary between home comfort and outdoor climate. Far beyond simple sun shading, these systems actively participate in year-round thermal management, architecture expression, and daily living quality.

Their construction is engineered for reliability in European climates, with durable materials and precise mechanical operation that respond predictably to seasonal demands. The profiles integrate seamlessly with any Internorm window system, maintaining coherent proportions and finish standards across the façade. Manual or motorized operation empowers residents with granular control over light, privacy, and natural ventilation — transforming passive viewing into active climate response.

During summer months, the shading function intercepts intense solar radiation before it enters the interior, maintaining comfortable indoor temperatures and soft, diffused ambient light. This passive cooling effect reduces reliance on mechanical air conditioning and extends periods of natural thermal comfort during peak sunlight hours. The darker, cooler interior protects furnishings and reduces visual fatigue for occupants.

In winter, the blinds retreat partially to allow low-angle sunlight to penetrate windows, contributing to passive solar gain. Their substantial construction simultaneously enhances the window system's thermal resistance, creating a more effective thermal buffer between interior warmth and exterior cold. This dual function — both solar capture and insulation — exemplifies integrated climate-responsive design.

Architecturally, Internorm blinds speak a language of refined simplicity. Neutral color palettes and clean geometries complement contemporary and traditional façades equally, never announcing themselves but always enhancing proportion and material expression. Available in configurations suited to renovation projects and new construction alike, they adapt to any opening size with graceful functionality.

For homeowners pursuing passive house standards, energy renovation goals, or simply elevated comfort, Internorm blinds are a tangible investment in living quality and year-round wellbeing. They embody the premium showroom approach of attending to details that transform housing into genuine home.

Schlotterer's aluminium slats (37 × 8 mm) feature internal PUR foam and UV-resistant paint, ideal for long-term durability and premium appearance. PVC slats offer a cost-effective alternative with 5 interior ribs for rigidity, requiring no UV maintenance. The choice depends on your budget and preference for metallic or plastic finish.

Schlotterer shutters reduce summer cooling energy consumption by up to 50%, representing significant savings in warm climates. In winter, thermal insulation improves by 25%, reducing heat loss through windows. This dual-season performance optimizes comfort and lowers energy bills year-round.

Yes, Schlotterer shutters are compatible with major protocols: KNX, Loxone, evonHOME, mediola, and io-homecontrol (Somfy). You can automate opening and closing based on time, sunlight intensity, or temperature. Integration enables mobile app control and customized intelligent scenarios.

Schlotterer shutters feature an anti-lift device (Hochschiebeschutz) that prevents mechanical forcing of slats. This security feature does not replace a complete protection system but adds an important layer of passive home defense. It is an effective solution for ground-floor and lower-level windows.

Schlotterer shutters offer over 200 RAL colour variants, enabling complete customization of your home. Housing is available in two models: VORO SICHT (straight, modern and elegant) and VORO BRAVO (curved, sophisticated appearance). Each combination mounts directly on the window, ensuring unified aesthetics with your home's architecture.

These shutters mount directly on the window—a straightforward, rapid installation requiring no structural modifications. Aluminium slats are UV-painted and require occasional washing with water and soap. PVC slats need no UV treatment and are extremely easy to clean, ideal for homeowners prioritizing low long-term maintenance.
