In fact, a lot of things can't make do with it, a temporary will only in exchange for the future regret, especially the doors and windows, which are closely related to our life.Some people will say, but it is to enjoy, cheap things can save a lot of money. But the same door and windows, the difference in price is reflected in the different aluminum specifications, different door and window glass, different hardware accessories, different factory equipment, different seal strip, different heat insulation bar, different drainage design and so on too many details are different. The doors and windows are related to the safety and comfort of home, the people who really care about their family, will spend money, understand life, will put their mind on the choice of good home products. Do not wait until the doors and Windows have been installed in the process to find that their doors and Windows are not sound insulation, not energy saving, not heat insulation, unsafe, not anti-theft. Good doors and windows have long service life, energy saving and environmental protection, safe and comfortable, it is necessary to buy more system for the doors and windows. Hihaus doors and windows, starting from safety , starting from comfort and convenience, with environmental protection and health as the concept, to redefine your high quality living life.

In this rainy and changeable season, It is also a time to test the quality of doors and windows at home. Only choose the right doors and windows, So I can enjoy it with confidence. NO.1 Windproof performance of profile It is an important feature of doors and windows, especially for high-rise residential windows. We use high-quality multi-cavity structural profiles with high strength, so they are corrosion resistance, oxidation resistance, and high toughness.Our workshop achieve high-precision cutting by advanced equipment .Tight joint can shelter homes from wind and rain. NO.2 Compressive performance of glass Glass has always been an important part of home improvement doors and windows, occupies 80% of the entire door and window area, and have a great performance in weatherproof. We use automotive-grade hollow safety double-layer glass certified by the national 3C, which has good compression and impact resistance, high flatness, and superior water tightness and air tightness.And all series of glass products have been purchased with insurance, so that users can be more assured. NO.3 Sealing structure of doors and windows It directly affects the air-tightness and water-tightness of doors and windows. The rigorous sealing structure design can prevent water vapor from entering and rainwater leakage which to keep the house dry. We use EPDM with superior sealing performance, which is resistant to aging, does not fade and seals well. In addition, the 90°corner adopts a special glue angle to transfer the integral continuous sealing surface of the profile, which ensures that the doors and windows have excellent sound insulation, waterproof and windproof performance. NO.4 Drainage design of doors and windows If the drainage is not done well, water leakage and seepage are more likely to occur on rainy days. We have a variety of different drainage designs to meet different opening methods of door and window products, which are practical and beautiful. Smooth drainage ensures strong watertight performance, allowing unobstructed drainage of doors and windows. NO.5 corner assembly process of doors and windows It has a great influence on the air tightness of doors and windows. If the assembly structure is unreasonable, the gap between the window frames will be too large, finally cause air and rain leakage. We use cast aluminum corner code with stainless steel pin glue injection technology, which greatly improves structural strength,sealing performance,and safety. It helps corner connection strength to be higher;corner code glue to be more reasonable and corner sealing performance to be better.
