Product Overview
Skylights, as special lighting and ventilation components at the top of buildings, achieve the three core functions of "natural light introduction, air convection, and space beautification" through scientific structural design and material selection. The product is suitable for various building spaces such as pitched roofs, attics, sunrooms, basements, and commercial atriums. It can significantly improve indoor lighting efficiency (the lighting area is 2-3 times that of ordinary side windows), form a three-dimensional ventilation circulation with "upper discharge and lower intake", and improve indoor air quality. At the same time, with a simple and smooth appearance design that integrates with the architectural style, it creates an open and transparent spatial texture. It is an important component in modern architecture that combines practicality and decoration.
Core Structure and Material Selection
(1) Overall Structural Design
The product adopts an "frame-glass-sealing-fittings-drainage" integrated structure, optimizing both structural stability and usage safety:
1. Frame System: The main frame uses 6063-T5 grade aluminum alloy profiles (wall thickness ≥ 1.4mm) or insulated aluminum profiles (wall thickness ≥ 1.6mm), with the surface treated by powder coating, fluorocarbon coating, or anodizing, possessing excellent corrosion resistance and UV resistance; the frame adopts a multi-chamber structure design to enhance insulation and heat preservation effects, and simultaneously improve overall deformation resistance, suitable for roof slopes of 15° - 60°.
2. Glass System: Standardly equipped with double-layer insulating tempered glass (5 + 12A + 5mm), which breaks into blunt-edged particles, without the risk of splashing and injuring people; optional include laminated tempered glass (PVB film thickness ≥ 0.76mm), Low-E insulating glass, and triple-layer insulating glass (5 + 12A + 5 + 12A + 5mm), respectively enhancing safety protection, energy-saving insulation, and noise reduction; the edges of the glass use butyl sealant + polysulfide sealant double-layer sealing, with an inert gas filling rate ≥ 90%, ensuring a moisture-proof sealing effect.
3. Sealing System: Uses high elasticity EPDM (triple rubber) sealing strips, with a Shore hardness of 50-60 degrees, a temperature resistance range of -40℃ - 120℃, and excellent anti-aging and tear resistance; a multi-layer sealing is formed between the frame and the glass, and between the frame and the roof structure, completely blocking the paths of water and air infiltration.

FAQ
1. What is the main function of a skylight? What are its advantages compared to ordinary windows?
The core function of a skylight is to increase indoor lighting, promote air circulation and ventilation, and create an open view and transparent space. Compared to ordinary windows, it can utilize the roof space to introduce natural light, has higher light efficiency, and can form an "upward-outward" air circulation, resulting in better ventilation; some skylights also have additional functions such as viewing, heat insulation, and sound insulation, suitable for special spaces like attics, sloping roofs, and sunrooms.
2. Is the waterproof performance of a skylight reliable? Why does it sometimes leak?
A qualified skylight product itself has reliable waterproof performance. Leaks are mostly caused by improper installation or maintenance later on. Common reasons include: aging and cracking of the sealant at the junction of the window frame and the roof; blockage of the drainage channels and drainage holes, preventing rainwater from being drained in time; failure to properly handle the lap treatment of the flashing board and waterproofing sheet during installation; aging and damage of the glass sealant strips, etc.
3. What are the opening methods of skylights? Which one is more suitable for home use?
The mainstream opening methods include up-hanging, mid-hanging, sliding, folding, and electrically operated. For home use, up-hanging or electrically operated up-hanging are preferred. During the up-hanging opening, rainwater will not backflow, and the ventilation volume is controllable, making the operation convenient; the electrically operated type is more suitable for installation on high places (such as attic sloping roofs), as it does not require manual climbing to open, and has higher safety.
4. Do skylight glasses require special configuration? Can they be replaced with tempered glass or Low-E glass?
Skylight glasses require special safety glass. The standard configuration is usually tempered glass or laminated tempered glass, which has no sharp fragments when broken, avoiding injuries from falling. According to the needs, it can be upgraded to insulating tempered glass (improving insulation and sound insulation performance) or Low-E insulating glass (enhancing heat insulation and energy-saving performance), but the glass thickness must be compatible with the skylight frame.
5. Can skylights be installed on high-rise residences or sloping roofs? What are the installation requirements?
They can be installed, but they must meet the building structure and safety standards. When installing on sloping roofs, it is necessary to confirm the roof slope (usually suitable for 15° - 60° slope), and select the appropriate skylight model for sloping roofs; for high-rise residences, the window frame fixation structure needs to be reinforced to ensure the wind pressure resistance meets the standards, and waterproof sealing and anti-fall measures should be done well. It is recommended to be constructed by a professional team.
6. Do skylights need regular maintenance? What are the key points of daily maintenance?
Regular maintenance is necessary to ensure the long-term use effect. Key points of daily maintenance: Regularly clean the leaves, dust, etc. in the drainage channels and drainage holes to avoid blockage and water accumulation; Check whether the sealant of the window frame and the roof, as well as the glass sealant strips, are aging and replacing damaged parts in time; Add lubricating oil to the hardware components (hinges, handles, etc.) of the skylight every six months to keep the opening smooth; Regularly clean the glass to avoid sharp objects from scratching.
7. How is the heat insulation and sound insulation effect of skylights? How to improve it?
Ordinary single-layer glass skylights have average heat insulation and sound insulation effects. Upgrading the configuration can significantly improve them. Selecting insulating glass (such as 5 + 12A + 5mm) or Low-E insulating glass can enhance the insulation performance and reduce heat conduction between indoor and outdoor; Combining with a sealing performance good TPE rubber strip can improve the sound insulation effect and isolate external noise. In addition, installing skylight sunshades (such as honeycomb curtains, blinds) can further optimize the heat insulation and privacy protection effect.
8. How long does a skylight have a lifespan? What factors affect its lifespan?
The lifespan of a high-quality skylight is usually 15 - 20 years. It is affected by the material, installation process, and maintenance frequency. The window frame material (aluminum alloy, which has stronger corrosion resistance, has a longer lifespan) and glass quality, as well as the durability of the hardware components, are the core factors determining the basic lifespan of the skylight; Standard installation and regular maintenance can effectively extend its service life.
9. Can skylights be equipped with shading facilities? What shading methods are available?
It can be installed. Common shading methods include built-in shading curtains (honeycomb curtains, blinds, roller blinds), external shading canopies, shading blinds, etc. Built-in shading curtains are aesthetically pleasing and easy to operate, and do not affect the opening of the skylight; external shading canopies have better shading and heat insulation effects, but they need to consider wind resistance and waterproofing issues, and are suitable for low-rise buildings or sunrooms.
10. How to choose between electric and manual skylights? Are the motors of electric skylights prone to failure?
Manual skylights have high cost performance and are easy to operate, suitable for installation in lower positions and scenarios with low opening frequency; electric skylights are more labor-saving, suitable for high-altitude installation or large-sized skylights, and can be paired with intelligent control systems to achieve remote control and automatic closing upon wind or rain sensing, suitable for families seeking convenience. Qualified electric skylight motors have a lifespan of 8-10 years. With daily dust and moisture protection maintenance, they are less likely to fail.
