Hardcore Material, Tough and Durable
● Broken Bridge aluminum doors and windows are made from 6060-T66 aluminum alloy, which is processed with high-temperature extrusion. This gives them a tensile strength of over 200MPa-more than triple what UPVC profiles can handle. Whether you're in a coastal area with lots of typhoons or somewhere very cold, these windows and doors stay strong and don’t warp or crack even after more than ten years.
● The plastic parts on UPVC doors and windows tend to wear out over time. Exposure to sunlight eventually causes them to fade, become brittle, or develop a powdery coating, which can lead to cracks, especially when it's cold. Usually, these doors and windows need to be replaced every 5 to 8 years. On the other hand, broken bridge aluminum doors and windows tend to last two to three times longer, which means they can save you money in the long run since you'll need fewer replacements.

Broken Bridge Technology, Highly Efficient Thermal Insulation
● Broken bridge aluminum doors and windows use "PA66 nylon thermal break strips plus a multi-chamber design" to help stop heat from passing through. When combined with insulating glass, the whole window can have a heat transfer value (K-value) as low as 1.2 W/(㎡·K).
● Even though UPVC doors and windows use their plastic frames' low thermal conductivity (about 0.16 W/(m·K)) to help with insulation, their basic design and the fact that they expand more than aluminum (seven times more, actually) mean they can bend or warp when it's really hot. This often makes the seal less effective over time.

Enhanced by Aesthetics, Diverse Customization Options
● Broken Bridge aluminum doors and windows go through 12 different surface treatments and come in more than 90% of the RAL color options. Their slim frames with big glass panels create a look where windows make up over 60% of the wall area.
● Because of how plastic profiles are made, most UPVC doors and windows tend to come in simple colors like plain white or wood finishes, usually with a matte look. That makes it pretty hard to get that shiny metallic shine or detailed textures.

Unafraid of Extremes, Safe and Reliable
● When it comes to wind resistance, our broken bridge aluminum doors and windows are built sturdy. They come with a multi-point locking system that can handle over 80kg at a single point, and the profiles are thicker too-wall thickness is at least 1.8mm. That means they’re strong enough to stand up to pretty severe storms, like Category 12 typhoons with wind pressures of 2.5kPa or higher.
● Because their profile isn’t very strong, UPVC doors and windows usually can handle winds up to just below Category 10. They mostly use simple locking systems, so during very strong winds, they can leak air or even come loose.

Environmentally Friendly with Remarkable Advantages
● Most of the raw materials for broken bridge aluminum doors and windows are made from recycled aluminum. The old profiles can be melted down and reused without any problems, so over 95% of the materials can be recycled again and again.
● Some of the plastic stuff used in UPVC doors and windows might not be great for your health. When these products are thrown away, they don’t break down easily, and burning them can release dangerous gases.

Right now, aluminum doors and windows made with broken bridge technology make up over 40% of the high-end market. They’re growing pretty fast too-around 18% a year-way more than UPVC doors and windows, which only grow about 3% annually. Greborn, with its solid experience in this area, stays dedicated to its core approach: combining technology, good design, and eco-friendliness. We keep working on customizing high-quality door and window solutions to meet what our customers need.
