ALT SP50 Sun-protection system

ALT SP50 Sun-protection system

The ALT SP50 system has been designed for fabrication of exterior sun protective constructions.

The use of exterior sun-protection systems is the simplest and the most effective method for passive cooling of building’s interior space. Owing to the bar constructions the majority of sunbeams stop before penetrating into a room. The space between facade and sun protection bars provides air circulation (ventilation).

The ALT SP50 system is vertically and horizontally equipped with fixed bar fastenings within covering brackets or on guide rails.

Depending on construction upload designer has the possibility to choose essential bracket type: universal or reinforced. Construction assembling and mounting are simplified to the maximum, profile treatment operations are minimized.

Bars dimensions are available from 100 mm to 280 mm with a range of polymeric or anodic coating which permits architects and designers to be able not just to engineer an exterior sun-protection construction, but also to form a unique view and additional volume for a building.

Fastening variants

I. Fastening in a covering bracket

II. Fastening on a guide rail


Sun protection bars stationary system: fastening of sun-protection bar within covering bracket: advantages  

I. Simple fastening of brackets to the ALT F50 Facade system
II. Possible use of several types of brackets
1. Universal brackets 0˚, 15˚, 30˚, 45˚ (for AYPC.SP50.0802- AYPC.SP50.0805 bar fastening)
2. Reinforced brackets 0˚, 15˚, 30˚, 45˚ for 240 mm bar (AYPC.SP50.0104)
3. Reinforced brackets 0˚, 15˚, 30˚, 45˚ for 280 mm bar (AYPC.SP50.0105)
Reinforced brackets are recommended for use with the system in high wind and glazing ice force areas!
III. Special jet nuts AYPC.SP50.0932, AYPC.SP50.0932-01, AYPC.SP50.0933, AYPC.SP50.0933-01 provide for
1. Firm bars fixing
1.1 Additional rigidity at junction of bracket and jet nut.
1.2 Essential force stability under positive and negative wind pressure.
2. Prevention of drops during “in-line” bar assembling
3. Simple assembly and installation of bars to building angle zones
Advantages: integrated solution for compensating for linear thermal expansion
Sun-protection bars system: Fastening on rails: advantages Optimal fastening with operations minimization
Possible system mounting when fastening consequently or modularly (with preliminary assembly in a workshop)
