When choosing building materials, consumers now focus on the U-value, a fundamental indicator of window and door thermal insulation. Through low U-value technological innovation, Greborn has not only transformed the energy-saving standards for windows and doors, but it has also had a significant impact on people's daily quality of life by improving "constant temperature, energy saving, and environmental protection" at home.

The lower the U-value, a crucial indicator of how well doors and windows transfer heat, the better the thermal insulation. Conventional windows and doors often have U-values between 2.8 and 3.5 W/K, which causes significant heat loss. However, thanks to technological advancements, Greborn has met international high-efficiency energy-saving standards by reducing the overall window U-value to 1.2-1.6 W/(㎡·K). "Low-E insulated laminated glass + extra-wide PA66 thermal break strips + three-channel EPDM seals," when combined with a multi-cavity profile design, is the secret. This eliminates the problem of "cold winters and hot summers" with conventional doors and windows by preventing heat transfer through conduction, radiation, and convection.

Greborn's low U-value doors and windows can cut heating energy use by more than 35% in colder northern climates, maintaining indoor temperatures 4-6°C higher than standard doors and windows during the winter and avoiding mold and condensation. They successfully block outdoor high temperatures during the south's sweltering summers, reducing air conditioning energy consumption by almost 30% and saving more than 1,000 yuan in electricity bills every year. More importantly, the steady indoor temperature greatly enhances living comfort by shielding children and the elderly from temperature swings. Additionally, the quiet sealing design isolates outside noise, resulting in a tranquil home.

Because they use less energy, Greborn's low U-value windows and doors indirectly lower carbon emissions. In line with the current development trend of green buildings and low-carbon living, a household that uses Greborn doors and windows can reduce carbon dioxide emissions by about 1.2 tons annually, which is equal to planting 60 adult trees. Because of their superior U-value performance, Greborn's products are widely used in residential buildings, commercial structures, and other settings. They have also received industry certifications and consumer recognition.
