Product core definition and applicable scenarios

Aluminum alloy sloping roof manual skylight is a customized lighting and ventilation skylight specially developed for 15-60 sloping roofs. It adopts an all-aluminum alloy integrated frame structure and is matched with a manual opening drive system. It does not require a motor or power supply. It can be easily opened and closed by relying on manual push rods and air braces. It is an energy-saving lighting and ventilation facility exclusive to sloping roofs.

In the building design code, the inclined roof is a special roof structure, and the ordinary flat roof skylight cannot adapt to the inclined drainage angle, which is prone to problems such as water accumulation, water seepage, opening card, and poor sealing. The special pitched roof manual skylight is designed according to the slope mechanics of the pitched roof, which fits the drainage flow of the roof and perfectly adapts to all kinds of pitched roof buildings.

Mainstream application scenarios: sloping roofs of self-built houses in rural areas, sloping roofs of villa attics, sloping roofs of bungalows, glazed tile/terracotta tile sloping roofs, asphalt tile sloping roofs, lighting and ventilation renovation of duplex rooftops, sloping roof windows in sun rooms, sloping roof lighting upgrades in storage rooms, etc.

Compared with electric skylights, manual sloping roof skylights have a minimalist structure, few accessories, no circuit failures, no fear of thunderstorms, and almost no maintenance in the later stage. They are the most cost-effective and stable mainstream choice for household sloping roof skylights.

Core materials and industrial-grade production processes (professional core)

The service life and performance of high-quality aluminum alloy pitched roof manual skylights depend entirely on the substrate material and production process, and there is a huge gap between high and low-end products in the industry.

1. National standard thickened aluminum alloy integrated frame

The whole system adopts 6063-T5 native aviation aluminum alloy profiles, which distinguish between recycled miscellaneous aluminum and thin aluminum. The frame is bent and seamlessly welded, and the overall strength is high, the toughness is good, the wind pressure resistance is not easy to deform. The wall thickness of the profile meets the industry engineering standard, which can resist high-altitude strong winds and hail impacts, and long-term exposure to the sun, rain will not rust, oxidize, and whiten.

The surface adopts outdoor-grade electrostatic powder spraying process. After pickling, phosphating, and anti-corrosion priming, the coating has strong adhesion, yellowing resistance, and UV resistance. It can be used outdoors for more than 15 years without fading or paint peeling, and is suitable for long-term open-air complex environments.

2. High-strength explosion-proof tempered glass

The pitched roof skylight is exposed outdoors for a long time, and the requirements for impact resistance and explosion protection are extremely high. Regular products come standard with 8mm-10mm national standard 3C certified fully tempered glass, and some upgraded models use laminated tempered glass, which has the characteristics of anti-hail, anti-impact and anti-self-explosion.

The glass has high light transmittance, uniform lighting is not dazzling, and at the same time, heat insulation and UV resistance can effectively block outdoor heat radiation, avoid the stuffy summer of the attic, and take into account the effect of lighting and energy saving. The corners of the glass are finely ground and chamfered, without sharp edges and corners, and the safety is far superior to that of ordinary glass.

3. Assist the air support to manually open the system

It adopts stainless steel high-pressure air support power structure, which is the core accessory for easy opening and closing of manual sunroof. The air support has uniform damping and buffer silence. Adults can easily open, close, and position and hover with one hand. The maximum opening angle can reach 80. Large ventilation area, no card and no noise for operation.

With a special metal manual lock, the window sash can be firmly locked after closing, windproof and anti-shaking, and the problem of shaking, abnormal sound and loosening of the window sash in windy weather is eliminated, and the safety is extremely high.

III. Multi-layer waterproof sealing structure (core technology of inclined skylight)

The biggest industry pain point of pitched roof skylights is water leakage and seepage. Most of the low-priced skylights on the market are simple splicing structures without exclusive drainage systems. They are prone to problems such as rain infiltration, roof seepage, and water accumulation in window frames after half a year to one year of use.

Regular aluminum alloy pitched roof manual sunroof adopts industry standard integrated drainage plate + multiple seals + isobaric waterproof structure to eliminate hidden dangers of water leakage from the source:

1. Integrated aluminum alloy drainage baseplate

The bottom of the skylight comes with a whole board bending forming drainage base, no splicing gaps, no welding loopholes, and completely fits the slope of the inclined roof. The rainwater is quickly diverted along the slope of the roof, without water accumulation or water storage, and completely solves the problem of rainwater backflow on the inclined roof.

2. Multi-layer EPDM sealing strip

The connecting position of the frame fan adopts EPDM integrated sealing rubber strip, which seamlessly fits around the whole window, which is resistant to high and low temperature, anti-aging, non-hard and non-shrinking. After closing the window sash, the rubber strip compacts the gap tightly to achieve complete sealing and block the penetration of rain, dust and cold air.

3. Waterproof design of outer slope gland

The outer side of the window frame adopts an outer gland cover water-shielding structure to cover the connection gap between the window frame and the tiles. The rainwater directly flows out along the tile surface and does not enter the inside of the window frame. Multiple waterproof layers of protection meet the long-term use standards for rainstorm, Meiyu and typhoon weather.

The whole waterproof system has been tested by rain and water pressure, and meets the waterproof construction specifications for roof doors and windows, truly realizing the waterproof effect of lifelong water leakage and maintenance-free.

Six, aluminum alloy manual sunroof industry purchase pit avoidance guide

1. Reject thin materials and aluminum sunroofs: Low-cost sunroofs are made of recycled aluminum and thin-walled profiles, which are easy to deform and oxidize, and can be used for 1-2 years to loosen and leak; the original thickened aluminum alloy integrated molding structure is preferred.

2. Reject products without integrated drainage board: the splicing skylight without an integrated drainage base has many gaps and is prone to water accumulation and leakage, which is the largest pit point in the industry.

3. Look for 3C tempered glass: Ordinary glass and semi-tempered glass are prone to self-explosion and have poor impact resistance. All tempered glass with 3C certification must be selected.

4. Check the sealing material: inferior rubber strips are prone to aging and cracking, and EPDM EPDM weathering strips must be selected.

5. Priority air support power structure: ordinary hinge opening is laborious and easy to sag, and air support power structure is easy to open and close and has a longer life.
