UPVC material is energy efficient and is a good choice for passive houses. The insulation of UPVC doors and Windows is superior: the plastic thermal conductivity of aluminum-plastic composite profiles is low, the heat insulation effect is 1250 times better than that of aluminum.

Coupled with good air tightness, even though it's tens of degrees below zero outside in cold areas, it's a different world inside. The sound insulation of UPVC doors and Windows is good, its structure is carefully designed and the joints are tight.

UPVC Windows are named in different series according to different depths of frame in the market, such as 50 series, 60 series, 70 series. We primarily utilize high-standard 70 series and 88 series.

The design of the profile features two-cavity, three-cavity, or multi-cavity structures. The more cavities, the better the insulation and sound insulation effect of the profile. In addition, the cavity with lining steel is larger than the others which can improve the strength and stability of doors and windows.
