2022 latest design American Single Hung Thermal Break Aluminum vertical Sliding Window with inside grill by Doorwin

Doorwin windows are made with a variety of high-performance glazing options to meet your energy performance and budgetary needs. For all windows and doors exported to North America, we provide fully heat-treated, tempered glass as standard. This provides extreme impact resistance to prevent glass breakage, reducing warranty claims. When broken, tempered glass uniformly shatters into small pieces for safety. Our standard glazing for the North American market is SGCC (Safety Glazing Certification Counciland IGCC (Insulating Glass Certification Council)certified for performance and safety.

Glazing performance is a key factor in lowering a structure’s overall energy usage. The glazing unit determines three factors that affect energy efficiency and comfort:

1) The flow of energy via thermal conductance.

2) The transmission of light which affects visibility, and the amount of solar heat gain.

3) The transmission of sound.

Experts estimate that 70 percent of energy loss occurs in windows and doors and 90 percent of window heat loss occurs through the glass. Triple glazing, low-E coatings, argon gas fill and warm edge spacers can improve the energy efficiency of glazing units by 40 to 50% to deliver maximum insulation, solar heat gain control, condensation resistance and UV protection.

From the sample you can see the integrated continuum wood, which we adopted is non-finger joint.

Regarding Aluminum-Clad

Our virtually maintenance free cladding is made of the finest extruded aluminum. Unlike our competitors who use a thinner gauge aluminum, our 1.4mm thick aluminum assures outstanding rigidity and deformation resistance. Our standard finishing option is a polyester powder coat for superior resistance to scratches, flaking and fading. Fluorocarbon coat finishing is available at request for extreme environmental conditions.

Regarding Installation

This flange,also called Nail Fin in U.S., would makes the installation much easier and convenient that means you would pay less labor cost on installation. We has already applied for the Product Patent for movable nail fin in China, which is for the convenient transportation.

Regarding Screen

Usually we use the removable screens that you can easy to clean when it becomes dirty. And for the colors, we could make any kinds of color as your requirement.
