1. Unique design of three soft seal greatly enhanced profile of the thermal insulation performance.
2. Visual acuity 2.5 ㎜ of wall thickness, the visual acuity 2.2 ㎜ side wall thick, conform to the profile of national standard GB/T8814-2004 - B type wall thickness requirements.
3. The unique design of anti-theft lock more design, falling prevention safety design, safety performance to solve outside the window.
4. The design of bolt connection technology, thoroughly eliminate the crack hidden danger of v-shaped welding, improve the connection strength and better cosmetic results.
Dedicated hardware accessories, stable open closed more smoothly, unique design of the clamp hand to ensure safe operation.
Combined closely with the profile more chamber structure, hollow glass, three seal design, heat insulation performance of K value as high as 1.70, sound insulation can reach 30 decibel.
Outstanding safety design
Hidden pry proof lock more lock design, use more secure.
Long service life
Integrated design, hardware accessories and profiles with high precision, can open closed the 150000 times, window into durable performance is better.
