The quality is very good, noise reduction, heat insulation and many other functions, and the accessories inside are domestic first-class, very good.
1. Thermal insulation - environmental protection and energy saving are infinitely beautiful.
The K value of the whole window of Meidun energy-saving doors and windows can be reached, and it is collected as an energy-saving model window by the most authoritative testing agency in China, the National Construction Engineering Quality Supervision and Testing Center. Meidun energy-saving doors and windows block heat from entering the room in summer, prevent indoor heat loss in winter, and keep the indoor warm in winter and cool in summer; Reduce the use of air conditioning, save the cost of cooling and heating, and effectively reduce the attack of air conditioning disease. If 10% of the country's buildings use Meidun energy-saving doors and windows, the energy saved in a year is equivalent to a Daqing oil field!
2. Sound insulation and noise reduction - quiet and pleasant every day.
Imported five-cavity profiles and high-quality sealing strips, with double-layer temperature screen energy-saving glass filled with 90%-95% argon, to ensure that the sound insulation performance reaches 50 decibels (the highest national six-level standard). 10-15 dB more insulation than other energy-saving products, allowing you to get away from the hustle and bustle of the city. Don't underestimate these tens of decibels, experiments have proven:
5 decibels is enough to wake up a baby less than a month old.
3. Filter UV - enjoy healthy sunlight.
Effectively prevent 95% of ultraviolet rays from entering the room, keep indoor ultraviolet rays within trace levels, prevent the aging and fading of indoor furniture, clothing, books, and collectibles, and avoid the damage of ultraviolet rays to the body, so that your family can fully enjoy the sun. Studies have shown that long-term exposure to ultraviolet rays can lead to cancer, and excessive ultraviolet rays can also cause damage to the cornea of the eye, which is one of the most important agents of cataracts.
4. Ultra-high light transmittance - extraordinary experience of new perspectives.
In the case of lower emissivity, the equipped warm screen energy-saving glass scientifically adjusts the thickness of the dielectric layer on the silver surface, so that the dielectric layer can play a role in increasing transparency. The visible light transmittance can reach more than 80% (about 65% for traditional low-E energy-saving glass), which can ensure good indoor lighting effect; Stable coating and hollow layer of high-purity argon, at minus 45 the inside of the insulating glass will not frost dew, but also give you an extraordinary new perspective!
Fifth, the sealing performance is good - refreshing, clean and more beautiful.
There is an independent drainage cavity and the use of high-quality EPDM sealing strip, the strip absorbs its technology and experience in high-end car accessories, the door energy-saving sealing performance is higher, and effectively prevents the rainwater backflow, moisture, odor and dust entering, to ensure that the home environment is refreshing and clean. At the same time, the design of the adhesive strip fully considers the beauty of the whole window, adding charm to your room.
6. Fresh air system - a window that can breathe.
Adopt advanced fresh air system, ventilation, cooling and dehumidification, and improve the indoor thermal environment; Ventilation improves indoor air quality, provides fresh, clean and fresh air, increases the oxygen content of indoor air, and excludes all kinds of harmful gases. It is conducive to people's physical and mental health, and meets people's needs for psychological closeness to nature and return to nature.

Do not drink the first installed solar energy, because during installation, the installer will use dish soap to lubricate the vacuum tube of the solar energy. >>>More
Polar ultra-cold tube, is the use of UTLET technology, interference membrane technology is a kind of vacuum tube, vacuum degree of 10 4 Pa, the inner membrane will not fall off and whitish within 15 years, is the type of vacuum tube of Huangming's high-end model, this is the vacuum tube selected by the Antarctic scientific expedition team, minus 40 degrees of thermal insulation performance and thermal efficiency improvement ability is still very good. The high-temperature tube and high-efficiency tube are actually ordinary vacuum tubes on the market, with a vacuum degree of 10 2 Pa, which is also very cheap. If you have to go from the outside, the purple color of the Huangming vacuum tube is heavier, you can stand up and try it, the real Huangming utlet polar tube can be flattened for four people without a problem.
Huangming now has optical circuit lights. Optical circuit lamp is a kind of lighting equipment that uses solar energy to generate electricity, which converts solar energy into electrical energy through solar panels, and then stores the electrical energy and supplies LED lights for lighting. >>>More
