B75 high-performance inner opening and inner inverted system doors and windows, 75mm multi-cavity broken bridge aluminum profile, with PA66 heat insulation strip, using pin glue injection group angle process, stable structure and strong wind pressure resistance. Three-way sealing structure with EPDM rubber strip to achieve high air tightness, with isobaric drainage design to ensure excellent water tightness and effectively prevent rainwater leakage.

Equipped with Low-E insulating glass to reduce heat transfer K value, thermal insulation, energy saving and noise reduction. Supports two opening methods: inner flat opening and inner inverted opening. It can be slightly ventilated in rainy days, and the glass can be cleaned indoors. Suitable for high-rise residences and villas, taking into account safety, performance and simple appearance, it is the preferred system window for home improvement.

System doors and windows hidden drainage

The hidden drainage of the system doors and windows adopts a built-in water guide cavity with profiles. Relying on the principle of isobaric cavity, rainwater can be quickly exported along the internal stepped channel after entering the frame. There are no exposed drainage holes on the outer facade, and the appearance is simple and flat, which improves the texture of the facade. Compared with traditional open drainage, it can reduce the risk of strong wind and rain water backflow and greatly improve the watertight performance of the whole window.

The complete cavity structure guarantees high air tightness, reduces wind noise, and reduces dust and mosquitoes entering the room from the drain hole. The drainage channel is reasonably planned, which is not easy to accumulate pollution and block. In heavy rain weather, it can also quickly drain the water in the frame, effectively preventing water seepage in the window frame and mildew on the wall. The structure is matched with multiple sealing strips, which are suitable for high-rise and villa home improvement, taking into account waterproof performance and aesthetic effect

System door and window fluorocarbon spraying

The system door and window profiles use fluorocarbon spraying process, and polyvinylidene fluoride fluorocarbon paint is sprayed in multiple passes and cured at high temperature to form a protective coating. The paint film has excellent adhesion, ultraviolet resistance and anti-aging, and is not easy to fade and chalk after long-term outdoor exposure.

The coating is resistant to acid and alkali, salt spray corrosion, effectively resists rain and atmospheric pollutant erosion, the surface is dense and smooth, and dust stains are easy to clean. The paint surface has a delicate texture, and a variety of matte colors can be selected, which is beautiful and atmospheric.

Compared with ordinary spraying, the fluorocarbon coating is wear-resistant and scratch-resistant, has a long service life, and the profiles are not easy to change color and peel. With high-performance system doors and windows, taking into account decorative aesthetics and outdoor durability, it is suitable for high-rise residences, villas and other home improvement scenes

HOPPE door and window handles

Germany HOPPE is a high-end handle brand of system doors and windows. It is suitable for inner opening and inner inverted windows. It adopts high-strength alloy raw materials and is forged by Seiko. It has passed millions of opening and closing tests and is durable. Equipped with Secustik anti-theft structure, the handle cannot be forcibly turned externally to improve home safety. The surface adopts professional coating process, which is resistant to corrosion, sun and rain, not easy to fade and paint off, and feels delicate and smooth. The style is simple and atmospheric, and the multi-color is optional, which can match all kinds of home improvement styles. The opening and closing damping is uniform, and the operation is quiet and not stuck. It is perfectly matched with B75 system doors and windows. It takes into account beauty, safety and long-term use stability. It is the preferred hardware accessory for

German Grid (GU) U slot hardware

The German GU U slot is open and inverted with hardware, suitable for aluminum profile U slot system windows, modular multi-lock point structure, strong load-bearing performance, and can bear large-size heavy window sash. The hardware is made of ferGUard anti-rust coating, which is corrosion-resistant and salt spray-resistant. After tens of thousands of opening and closing tests, it is still smooth and silent for long-term use.

Multi-lock point synchronous locking, greatly improve the air tightness, water tightness and anti-theft and anti-prying performance of the whole window. After closing, the lock point evenly presses the rubber strip to reduce air leakage and water seepage. Hidden structure design, simple and beautiful appearance, supports two opening modes of inner casement and inner inversion, and is suitable for high-performance system doors and windows such as B75. Easy installation and debugging, strong stability, it is the preferred imported hardware for high-end home improvement system windows

This picture shows the cross section of the door and window profiles of the B75 high-performance inner opening and inverted system. It adopts a multi-cavity broken bridge aluminum structure and is matched with PA66 heat insulation strips to effectively block cold and heat conduction, reduce heat transfer K value, and achieve excellent energy-saving and thermal insulation effect. The profiles have multiple sealing grooves, which can be equipped with multiple EPDM sealing strips to ensure high airtightness and high water tightness. The cavity has been strengthened to improve the overall rigidity, enhance the resistance to wind pressure, and is suitable for high-rise use. Built-in hidden drainage cavity, relying on the principle of equal pressure to quickly drain rainwater and avoid leakage. The slot is adapted to U-slot imported hardware, and the multi-lock points are pressed synchronously, and the lock is stable. The overall structure is scientific, taking into account sound insulation, heat insulation, waterproof and structural strength. It is the preferred profile for high-end system windows for
