ZDTM53 series energy-saving inward folding door
- ZDTM53 series energy-saving inward-folding folding door system is a high-end energy-saving inward-folding folding door system developed by our company based on European advanced technology and design concepts in response to the needs of the Chinese door and window market. It can achieve the largest opening area and is suitable for balcony doors in high-end buildings.The system has rich opening functions, which can realize multiple opening methods such as inward opening, inward folding, etc., which can easily meet the requirements of opening wide openings, and open the room in a smart and effective manner. Opening, creating an elegant entrance to the external environment, effectively covering the interior space.The system has a scientific and reasonable cross-section structure, standardized supporting hardware accessories, mature and standardized processing and construction technology, which can well guarantee the quality and performance of the product.Features1. Insulation performance: Insulating glass is configured according to the standard （6 + 12A + 6Low-E）. The overall insulation performance can reach level 5, that is, 3.0> K≥2.5W / （m2? K）, and the configuration can be adjusted up to 5 according to demand. Above.2. Wind pressure resistance: rigid design meets different load requirements. The wind pressure resistance can reach more than 6 （3.5≤P ＜ 4.0 KPa）.3. Watertight performance: The scientific principle of equal pressure cavity drainage is adopted, and the drainage is blocked. Watertight performance can reach level 5 （500≤ △ P ＜ 700Pa）.4. Air-tight performance: Reasonable structural design and high-quality sealing materials ensure the integrity of the seal. The air-tight performance can reach level 4 （the index value of the unit slit length is 2.5≥q1 ＞ 2.0 m3 / （m? H）, or the unit The area classification index value is 7.5≥q2 ＞ 6.0 m3 / （m2? H））.5. Sound insulation performance: up to level 3 （30≤Rw + Ctr ＜ 35dB）.6. Hardware accessories: adopt standard European standard hardware notches, which can be matched with multiple brands of hardware.7. Profile: The design wall thickness of all the main members is 2.0mm.
