Window Systems for Year-Round Comfort

Summer by the window feels a wave of heat; winter near the window, the chill is piercing. Even with the air conditioner or heater on full blast, it seems the warmth or coolness always escapes.

What's the issue? It's the window.

The difference between a good window and an ordinary one lies in year-round comfort: warm in winter and cool in summer.

Dejiyoupin Tianji System's airtight inner-opening windows are designed for the severe cold climate of the north, taking thermal insulation and energy saving to the extreme.

4SG Glass: The "Stabilizer" for Four Seasons Comfort

Many people have this experience: summer by the window feels a wave of heat; winter near the window, the chill is piercing. This is because the thermal insulation and heat preservation performance of ordinary glass is too poor.

Tianji flat-swing windows are equipped with German Kommerling ultra-white 4SG glass, featuring a triple-glazed and double-chamber structure. The 4SG uses flexible warm edge technology, with superior sealing performance compared to ordinary double-glazed glass.

Summer heat insulation, winter heat preservation, with multi-chamber design, inert gas filling, and ultra-wide thermal insulation strip design, form a complete thermal insulation system. This effectively blocks the exchange of indoor and outdoor heat, while significantly reducing the probability of fogging and condensation, keeping the view clear at all times.

Three Seals Keep the Cold Wind Out

Summer cool air escaping, winter heat escaping, all due to poor sealing.

Tianji system windows use a three-seal structure, equipped with new Anton EPDM三元乙丙胶条 and one-piece bent duckbill seal strips, which are aging-resistant and have a long service life. Close the window, and the cool air is locked in, the heat is retained, the wind cannot enter, and the temperature does not escape.

Akzo Nobel Powder Coating for Long-lasting Beauty

Northern ultraviolet radiation is strong, and the temperature difference between winter and summer is large. Ordinary windows easily fade, turn white, and peel off the surface after long-term use.

Tianji system windows use Akzo Nobel powder coating, a global paint brand with ultra-vulnerable technology. After years of use and exposure to the sun, rain, and snow, it still maintains full color and delicate texture.

Exceeding National Standard Wall Thickness for Stable Protection

Summer typhoons are frequent, and winter north winds are strong. Tianji system windows use 2.0mm wall thickness exceeding national standards and 6063-T5 original aluminum alloy profiles, with wind pressure resistance up to the highest level of 9.

Closed cavity pressure line, inverted hook design, tightly gripping the profile, stable as a rock in strong wind weather.

Wihagen Hardware: Details Show True Quality

Equipped with the full set of German Wihagen hardware system. The baseless antibacterial lever handle has an antibacterial rate of 99.9% or more, clean and hygienic. Anti-torque transmission box, smooth opening and closing without deviation. With 180° inward opening and inward tilting accessories, safe load-bearing, easy to open and close, control air volume. Double protection with safety collision angle and safety lock point lock seat.

Inward Opening and Inward Tilt for Easy Switching

Inward tilting opening, rain and dust-proof, even in rainy and snowy days, it can achieve slight ventilation, and the cold wind does not blow directly. 180° inward opening, more smooth air exchange, does not occupy indoor space.

Inward opening and inward tilting window

In the north, the first lesson in window selection is insulation.

A good window is more than just temperature. It's the comfort of sitting by the window in winter, the clarity of pulling back the curtains in the morning, the number on the heating bill, and the window still looking new after many years.
