Q:What is the main difference between single-hung and double-hung windows?

On a single-hung window, only the bottom sash is operable and moves up and down, while the top sash remains fixed. On a double-hung window, both sashes (top and bottom) are operable and can tilt inward for effortless cleaning and ventilation control.

Q:Are these windows easy to clean from the inside?

Yes! Our single and double-hung windows are designed with unique tilt-out sashes. This allows you to easily tilt both the upper and lower sashes inward to clean the exterior glass safely from inside your home.

Q:Do you support customization in designs and sizes?

Absolutely. We offer a wide variety of architectural designs, grid patterns, frame colors, and custom dimensional sizing to ensure that your new or replacement windows fit your project requirements perfectly.

Q:How are the windows securely packaged for international transport?

We utilize standard, heavy-duty export packaging which includes thick protective foam layers, reinforced corner guards, and solid wood crates or pallet structures to keep the windows completely stable and safe during long-distance transit.

Q:What certifications do your window products carry?

Our window series are strictly manufactured to meet major international standards. They hold official certifications covering wind load resistance, air infiltration, structural integrity, and thermal performance.
