PNTC62 series energy-saving inward-opening tilt-window system is a high-end energy-saving inward-opening window system developed by our company based on European advanced technology and design concepts in response to the needs of the Chinese window and door market. Its excellent safety performance, physical properties, thermal insulation performance and humanized opening method have been widely recognized by the market, and it is one of the window types beloved by customers.
The system can realize two kinds of opening methods: inward flat opening and inward tilting, which can easily meet the need to open the room in a smart and effective way. When you need to clean the outside glass of the window sash or you need a large amount of ventilation, you can open the window sash; when you only need a certain amount of air in the room, you can make the window sash in an “inward tilt state”.
The system has a scientific and reasonable a 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.
1. Insulation performance: Insulating glass is configured as standard （6 + 12A + 6Low-E）, and the overall insulation performance can reach level 6, that is, 2.5> K≥2.0W / （m2? K）, and the configuration can be adjusted to 6 by adjusting Above.
2. Wind pressure resistance: rigid design meets different load requirements. The wind pressure resistance can reach more than 9 （P≥5.0KPa）.
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. Airtight performance: Reasonable structural design and high-quality sealing materials ensure the integrity of the seal. The airtight performance can reach level 8 （the index value of the unit slit length classification q1≤0.5m3 / （m? H）, or the unit area classification Index value q2≤1.5m3 / （m2.h））.
5, sound insulation performance: up to 3 c.
6. Hardware accessories: adopt standard European standard hardware notches, which can be matched with many brand hardware.
7. Profile: The design wall thickness of all the main members is 2.0mm.
