Our aluminum Single and Double Hung Windows feature slender leaf & frame profiles. The structural depth of window profiles is 45 mm for frame and 26 mm for leaves. One great advantage of this window system is its drives, which are concealed in the leaf profile. This can enhance the aesthetics of your home, creating a seamless and uninterrupted view. These windows are constructed with hardware manufactured by industry recognized companies; enabling the final appearance and functionality of your home to a high standard finish. Installations are quick and easily prefabricated as they no longer need labor- intensive mechanical processing.
