Lighting structure and components
Each skylight, depending on the type of design and function, includes the following main components: 1. Frame: usually made of aluminum, fiberglass or PVC to ensure light weight and corrosion resistance.
2. Dome / Glazing: It is designed from double-walled polycarbonate, tempered glass or transparent U-PVC to provide both light transmission and thermal insulation.
3. Insulation and gaskets: they are responsible for preventing water and dust penetration.
4. Ventilation or opening system (in smart skylights): in electric or manual models, it provides the possibility of air conditioning.
Types of skylights in terms of design and application
Type of lamp | structural feature The main use of Bubble Skylight Polycarbonate or acrylic hemispherical cover commercial and office buildings |
Flat Skylight | Flat glass surface with aluminum frame Tubular Skylight villas and educational centers Light transmission through the reflector tube from the ceiling to the space Corridors and services, Polycarbonate Rooflight UV resistant with double or triple insulation Shed, factory, greenhouse Electric and smart skylight It has electric motor, rain sensor and remote control Modern projects and building automation
Standards and technical requirements In the design and installation of skylights, compliance with the following national and international standards is mandatory:
ISIRI 7175: General specifications for windows and weather sealing.
ISIRI 8593: Characteristics of toughened and laminated safety glasses.
EN 14351-1: Performance of doors and windows in terms of water, air and thermal resistance.
ASTM E283 / E331: Air and water penetration test in skylight structures.
Advantages
✅ providing natural light and reducing electricity consumption by 30%
✅ Improve mental health and increase work efficiency
Visual beauty and increasing currency of building architecture
✅ Ability to combine with natural ventilation (Passive Ventilation)
Executive tips in projects
1. The orientation of the skylight should be designed based on the path of the sun (south-southeast angle).
2. For sandwich panel or composite roofs, special waterproof frames are used.
3. In areas with high rainfall, drainage slope and use of EPDM gasket is necessary.
4. The use of anti-UV polycarbonate is recommended for more durability of the surface.
In recent years, the use of skylights in residential and office projects in Iran - especially in cities such as Isfahan, Tehran and Kerman - has grown significantly. Construction companies such as Sial Pihad Parsian, by using light and resistant materials (polycarbonate and anodized aluminum), provide solutions to increase natural light without wasting energy.
Summary
Skylight is not only a solution to save energy, but also one of the smart design elements in sustainable architecture. Choosing the right type of skylight, complying with standards and strictly implementing technical details, guarantees its optimal performance and longevity.
