The window frame adopts a vertical isotherm design and a 35.3 super-large insulation strip design, which has better insulation performance and is suitable for areas with larger temperature differences. It has better thermal insulation performance, flush inside and outside, and inward-opening windows with a wider field of vision. The inward casement windows equipped with three layers of tempered ultra-transparent glass (5mm+16A+5mm+16A+5mm). The three layers of glass can more effectively isolate high-frequency noise and effectively reduce noise by 35 decibels. At the same time, it can effectively isolate infrared rays and has better thermal insulation performance. Hoppe brand hardware handles are standard, Noto brand hinges are standard for inward opening and tilting, and Keneng brand hinges are standard for single inward opening windows. The windows open inwards can be made of glass guardrails and tempered laminated glass. It can be made of inward-opening micro-ventilation, which is suitable for ventilation without opening windows.
