HYGT84C/120C series of heat-insulating sliding windows are products that adopt a square and simple style and are built with systematic thinking.

The lower rail adopts stepped hidden drainage + stainless steel rail + double retaining edge, which is waterproof and drainage. Invisible drainage design uses water pressure to drain water, which is smooth and beautiful in appearance. The lower rail can be equipped with handrail tube.

The vertical edge seal and the upper rail, lower rail, and fixed horizontal frame are spliced at 90 degrees, which is easier to waterproof.

The multi-layer siliconized strip design blocks strong winds layer by layer, and is insect-proof, dust-proof, and waterproof.

The ultra-high sliding and unique isobaric cavity principle design ensure that there will be no water accumulation and leakage in the case of strong winds and rainstorms.

The use of precise craftsmanship and high-quality pulleys has higher strength and wear resistance, making the doors and windows easy to push and pull, smooth, and more flexible to open.
