1. UPVC doors and windows have good thermal insulation: the plastic in the aluminum-plastic composite profile has low thermal conductivity, and the thermal insulation effect is 1250 times better than that of aluminum. В дополнение, it has good air tightness. In cold areas, even if the outdoor temperature is dozens of degrees below zero, the indoor temperature is another world. …

Advantages of 65 series upvc profile for windows and doors 1–Thermal Insulation: LUYANG upvc windows profile is designed with chamber style, has a good heat insulation performance. Its heat transfer coefficient is low, so I can keep your house warm in winter and cool in summer. 2–Fire Retardant: LUYANG upvc profile not burn itself: the product extinguishes immediately when the external flame source is …

Первый, look at the appearance. High-quality profiles have uniform dimensions, reasonable inner cavity structure, soft color, smooth protective film, no bubbles, and the extended wall thickness is generally 2 миллиметр. Second, check whether the packaging of the profile (То есть, the protective film on the profile is also the trademark) is flat and smooth, whether there are bubbles, and whether …

The thermal insulation effect of windows is the most important indicator for measuring the energy saving of windows. The meaning of U value (heat transfer coefficient) is the amount of heat transferred through an area of ​​1 square meter in 1 hour. Simply put: the lower the U value (heat transfer coefficient), the better the thermal insulation effect of the …
