First, what is an electric sliding sunroof, product positioning and applicable scenarios
Schematic diagram of the opening structure of the electric translating sunroof

Electric sliding sunroof belongs to the category of intelligent lighting and smoke exhaust sunroof, which is different from the upper hanging sunroof and fixed sunroof. It relies on the motor to drive the transmission mechanism, and the window sash slides horizontally along the track to achieve opening and closing. It is a very popular smart sunroof category in sun rooms, attics, basements, and factory roofs.
Many customers are easy to confuse the electric panning sunroof with the electric upper hanging sunroof. The upper hanging window is turned up and opened, and the opening is small; the panning sunroof can realize a large opening ventilation surface, and the ventilation area can be up to half of the hole, and the ventilation efficiency advantage is outstanding. It integrates multiple functions of lighting, ventilation, smoke exhaust, and intelligent control. It has both home improvement and leisure properties, and also meets the hard requirements of industrial fire smoke exhaust.
Home improvement scenarios are mostly used in villa attic skylights, terrace sun roof skylights, and basement lighting wells; engineering scenarios are used in steel structure workshops, exhibition halls, swimming pools, large lighting roofs, and fire exhaust channels. According to the use, it is divided into household lighting and ventilation models and fire linkage smoke exhaust models. The motors, control systems, and acceptance standards of the two are completely different, and they need to be clearly distinguished when purchasing. Our manufacturer supports customization according to the size of the hole, and undertakes home improvement sun room matching and industrial roof smoke exhaust skylight projects.
Second, the electric sliding sunroof implements the requirements of national standards and fire protection codes

Electric translation sunroof is divided into two sets of standard systems: ordinary ventilation sunroof and fire smoke exhaust sunroof, which cannot be confused. Ordinary household ventilation electric translation sunroof, refer to the general technical conditions of JG/T 317 building sunroof; fire-fighting electric translation smoke exhaust sunroof, must comply with GB 50016 building design fire protection code, GB 16806 fire linkage control equipment standard.
The fire-fighting panning sunroof is the end device of the fire-fighting smoke exhaust system. It needs to be equipped with a fire-fighting special motor, a fire control box, and a smoke temperature detector. It is connected to the fire-fighting host and automatically opens the smoke exhaust when a fire occurs. It needs to have 3C fire protection certification. Products without certificates cannot pass the fire inspection.
The specification has indicators for the opening speed, opening angle (translation opening stroke), fire integrity, waterproof performance, and wind pressure resistance grade of the sunroof. High-rise roofs and sunroof in sun rooms must also meet the three tests of wind pressure resistance, water tightness and air tightness. There is no mandatory 3C requirement for home improvement self-use sunroof, but it still needs to meet the requirements of roof waterproofing and structural safety. Many sun room water leakage hazards are caused by the selection and installation of sunroof that do not meet the roof drainage logic.
III. Classification and characteristics of mainstream styles of electric translating skylights

According to the structural form, the mainstream is divided into a single group of single-fan translational skylights, double-fan folio translational skylights, multi-fan linkage translational skylights, as well as hidden embedded translational skylights and roof-raised translational skylights.
Single translating skylight: A window slides along one side of the track, suitable for small and medium-sized openings. The width of the opening is generally 0.8 to 1.5m. It is mostly used for small lighting openings and small sun rooms in attics. It has a simple structure and moderate cost. It is a commonly used model for home decoration.
Double fan folio translation skylight: The two windows translate in reverse to both sides. Under the same hole size, the ventilation opening is larger and the ventilation effect is best. The large hole in the sun room is preferred.
Multi-linkage translating skylights: three or more window sashes are synchronized and sliding, suitable for super-long lighting roofs and large-scale lighting roofs in factories. They are mostly used for large-scale lighting roofs in projects, and the precision of synchronous transmission systems is higher.
Hidden built-in translational skylight: The window frame is sunk into the roof keel, and the top and roof top are as flush as possible, beautiful and simple, with small wind resistance; the disadvantage is that the design requirements of the drain tank are high and the cost is higher; the base of the high-rise skylight is raised, the drainage cavity is larger, and the waterproofing in the rainstorm area is more secure.
The glass configuration can be matched with single-layer tempered, hollow tempered, and laminated hollow Low-E glass, which can be selected according to the needs of thermal insulation, sound insulation, and anti-smashing.
IV. Detailed explanation of electric translational sunroof profiles, glass, and sealing and waterproofing systems
Close-up drawing of skylight profile section and multi-channel sealed waterproof node

The electric translating skylight is exposed to the roof for a long time, exposed to the sun and rain, and the profile and waterproofing are the core. The mainstream profile adopts 6063-T5 high-precision aluminum alloy, multi-cavity broken bridge structure, and the broken bridge cavity blocks the conduction of cold and heat to reduce condensation. The surface of the profile adopts electrostatic powder spraying or fluorocarbon spraying, which is resistant to ultraviolet rays, and is not easy to fade and peel when used outdoors. The inferior products use thin materials to recycle aluminum. The frame is deformed under strong wind load, the track is deviated, and the window sash is stuck.
Glass is the key to the safety of skylights. Ordinary glass is strictly prohibited for roof skylights, and the minimum configuration is tempered glass. 5 + 12A + 5 hollow tempered Low-E is preferred for villa sun rooms to keep warm and insulate from ultraviolet rays. Laminated insulating glass is recommended for rooftops and high-rise roofs. After the glass is broken, it will not fall directly, which is safer.
The waterproof logic of the translational sunroof is different from that of the upper hanging window. It adopts layered stepped drainage + isobaric cavity waterproofing, not simply relying on gluing and sealing. The track is equipped with a multi-stage drainage tank inside, and the rainwater first enters the outer drainage chamber, and is discharged to the roof along the preset falling water channel, which will not flow to the indoor side; with EPDM EPDM automotive-grade sealing strips, multi-channel pressing and sealing, the rubber strips are resistant to high and low temperatures, do not age at high temperatures, and do not harden at low temperatures. Many low-cost translational sunroofs simplify drainage cavities, relying only on one layer of rubber strips to block water, which is very easy to

Whether the electric translating sunroof can operate stably for a long time depends on the drive system. Mainstream drives are divided into synchronous belt drive and rack and pinion drive. The synchronous belt runs silently, suitable for home improvement sun rooms and villa attics; the rack and pinion has stronger bearing capacity and large thrust, suitable for large-size heavy-duty sunroofs and industrial smoke exhaust sunroofs.
The motors are divided into household DC motors and smoke exhaust motors for fire protection. Household DC 24V low-voltage motor, safe voltage, no risk of electric shock when touched, supports remote control, mobile APP, and wind and rain induction; the fire motor is 220V for fire protection, with power-off backup power supply. After power failure, smoke exhaust can still be turned on and linked with the fire host.
The control system is rich in accessories: remote control switch, wall manual switch, wind and rain sensor, rain sensor, smoke temperature sensor, mobile phone smart module. Wind and rain sensor is a very practical configuration for home improvement. It automatically closes the sunroof when it rains to avoid rain entering the room.
The track adopts thickened aluminum alloy guide rails with built-in guide pulleys, and the pulleys are made of wear-resistant nylon or stainless steel wheels to reduce friction and abnormal sounds. Multi-linkage skylights must be equipped with synchronizers to ensure that multiple windows slide synchronously, without deviation or stagnation. Many low-cost skylights steal synchronization components, and the sash is misplaced and stuck after a period of use.
VI. Key parameters of the electric translational skylight, hole reservation and load design
Skylight opening size, itinerary marking drawings

It is a very common problem to reserve the hole in the early stage of purchase. The electric translation sunroof has an effective opening stroke, which does not mean that all the holes are opened. When placing an order, you must divide the cleaning hole, the size of the outer frame, and the opening stroke. For example: the hole width is 2m, and the double fan is opened and translated. The maximum opening stroke is generally half of the hole.
The width of the conventional home improvement skylight hole is 0.8-3m and the length is 1-4m; the engineering multi-connected skylight can achieve a longer combination. Roof installation needs to calculate the roof load in advance. The steel structure and roof purlins of the sun room must reserve the weight of the skylight and the snow load. In the snow-thick area in the north, the load-bearing of the steel structure should be increased to prevent the snow accumulation from deforming the skylight frame.
The opening direction and track layout should also be planned in advance: move left and right for a single fan, and open the double fan, and the drawings are clearly marked. At the same time, consider the roof slope. The translational skylight is suitable for roofs with a slope of 2-30. The drainage flow rate of roofs that are too flat is slow, and the risk of water accumulation is high, so the drain tank needs to be increased. For roofs with too large a slope, the window sash needs to slide under its own weight, and a self-locking motor needs to be brought. After closing, it will automatically lock to prevent self-sliding.
VII. Standardized construction process and installation focus of electric moving skylights
Construction site diagram of sunroof base fixing, track leveling, sealing and gluing

Electric translation sunroof installation process: hole structure review base reinforcement leveling sunroof outer frame in place leveling fixed base, structural glue track correction fixed motor, transmission mechanism assembly and debugging glass installation, rubber strip assembly drainage system dredging controller wiring, wiring debugging waterproof closure, roof coil lap opening and closing test, finished product acceptance.
The most important thing in the installation of the translational sunroof is that the track must be kept level, the horizontal error is too large, and the window sash sliding card and synchronization fail; the roof waterproof layer and the sunroof base must be professionally flushed and overlapped, and the roof waterproof membrane is turned up to the edge of the sunroof to form a water stop flanging. This step is the key to preventing water leakage. Many construction teams omit flooding and directly glue, and the glue seeps immediately after aging.
In terms of wiring, the home improvement low-voltage motor control cable can be hidden inside the keel of the sun room; the fire exhaust skylight line needs to use fire-resistant cables and be laid separately to meet the fire electrical specifications. After installation, repeat the full-stroke opening and closing test many times to check whether the sliding is smooth, whether the induction function is normal, and the drainage holes are all dredged, and cannot be blocked by foam or glue.
Eight, electric translation sunroof common faults, daily maintenance plan
Sunroof card, rubber strip aging, motor failure real picture
Long-term outdoor use, electric translation sunroof common faults: sash sliding card deviation, motor abnormal sound, remote control failure, drain hole blockage water seepage, rubber strip aging leakage, wind and rain sensor no response.
Daily maintenance points: clean up the fallen leaves, dust, and sediment in the track every quarter. The sediment gets stuck in the pulley track, which is most likely to cause the window sash to get stuck. Regularly dredge the drain holes of the drain tank, and the fallen leaves and debris block the drainage channel. Rainwater overflows into the room. Check the sealing strip for hardening, cracking, and shrinkage and replace it in time.
Transmission parts, pulleys can be sprayed with a small amount of silicone-based lubricant, the use of oil is prohibited, the oil is stained with ash to form sludge, which intensifies wear and tear; the motor and electronic control main board avoid long-term soaking in water, the sensor is tested once a year, and the rain induction is tested. Automatic window closing function.
Fire-fighting smoke exhaust skylights are regularly tested in accordance with fire protection requirements to ensure that the power-off backup power supply is normal, the smoke sensing linkage opening function is effective, and if the fire inspection fails, rectification will be ordered. Clean up the snow on the top of the skylight in time after snow to avoid long-term heavy load compression of the frame and track.
Nine, electric translation sunroof purchase pit avoidance guide, home improvement and engineering selection suggestions
Comparison chart of high-quality sunroof samples and subtracted inferior samples

There are many low-cost translation sunroof routines in the market, and procurement needs to be paid attention to. First, to distinguish between ventilation models and fire smoke exhaust models, engineering fire protection projects, be sure to confirm the 3C certificate and test report, and do not replace ordinary household sunroof; second, confirm the wall thickness of the profile, whether the bridge structure is broken, and the glass configuration. Many merchants verbally say laminated glass, but in fact only use single-layer tempering; third, confirm the transmission mode and motor type. Do not match the large and heavy sunroof with a small thrust synchronous belt motor. If the thrust is insufficient, it is easy to burn the motor.
Home improvement sun room, attic, priority broken bridge aluminum + hollow Low-E glass + low-voltage DC motor + wind and rain induction, taking into account comfort and intelligence; factory fire smoke exhaust project, using rack and pinion heavy-duty transmission, fire special motor, matching fire linkage box; rainy and rainstorm areas give priority to raising drainage base style; northern snow areas, strengthen structural load-bearing.
The glass is fragile during transportation, and the track is easy to bump and deform. When the goods arrive, check the frame, glass and track for deformation and damage one by one, and check the list of accessories before entering the site for installation.
Summary: The advantages and applicable value of electric moving skylights
Panorama of the completion of multiple sets of electric translation skylights in the sun room

Compared with the upper hanging skylight and the fixed skylight, the biggest highlight of the electric translating skylight is the large opening surface, high ventilation efficiency, convenient operation of intelligent electronic control, taking into account lighting and ventilation, and can also realize the function of fire and smoke exhaust, which is suitable for a variety of scenarios in villa attics, sun rooms, and factory lighting roofs.
However, the translational skylight structure is complex, the track, transmission, and drainage systems are precise, and the requirements for profile technology, waterproof nodes, and installation and construction are very high. It cannot be simply purchased according to ordinary lighting skylights. As long as the structural configuration is selected, the waterproof nodes are controlled, and the installation is standardized, the electric translational skylight can be used stably for a long time, bringing better ventilation and lighting experience to the sun room and attic.
