Reliable Double-Hung Window Manufacturer from China
In double-hung windows, both the upper and lower sashes slide vertically within the frame. Because they do not swing into the room, curtains, blinds, and items placed on the windowsill are not disturbed during operation.
Grandsea Windows and Doors designs and manufactures the perfect double-hung window for any application. We position the meeting rails to ensure a clear, unobstructed view whether you are sitting or standing. Double hung windows are available in standard sizes and custom sizes to ensure a precise fit for any project. For larger openings, double-hung windows are often combined with other window styles, such as fixed picture windows, to create a versatile and expansive glass area.
While traditional double-hung windows could be difficult to clean, modern designs have solved this problem. Grandsea’s double-hung windows feature convenient tilt-in sashes, which allow you to easily and safely clean both the interior and exterior glass surfaces from inside your home. Easy cleaning of both interior and exterior surfaces is made possible by features like tilt latches and window sashes that can be tilted in for added convenience.
Our double hung windows allow both upper and lower sashes to be opened at the same time, creating excellent natural ventilation effect and effectively improving indoor air quality.
The opening degree of the upper and lower sashes can be freely adjusted to accurately control the ventilation volume to meet the needs of different seasons and weather.
Equipped with a multi-point locking system and tempered glass, it greatly improves home security and gives you peace of mind.
The innovative tilting design allows the sash to tilt inward, allowing you to easily clean the outer glass without the help of ladders or professional tools.
Adopting advanced Low-E glass and sealing technology, it effectively blocks heat transfer, helping you reduce energy consumption and save money.

Introduction to Double Hung Windows
Double hung windows are a popular style that brings both traditional appeal and modern functionality to any home. Characterized by two operable sashes, these hung windows can be opened from either the top or bottom, allowing homeowners to easily control airflow and enjoy more fresh air throughout their space. This superior ventilation makes double hung windows an excellent choice for rooms where air circulation is a priority.
One of the standout features of double hung windows is their tilt-in design, which allows for easier cleaning of both the interior and exterior glass surfaces. This means less hassle and lower maintenance for busy homeowners. Whether you’re installing windows in new construction or replacing old ones, double hung windows offer a perfect fit thanks to their versatile sizing and classic look. Their two sashes not only enhance ventilation but also provide easy access for cleaning, making them a low-maintenance and practical solution for any room.
With their timeless design and functional benefits, double hung windows remain a popular style among homeowners looking for the perfect combination of beauty, convenience, and performance. Whether you’re seeking to add a touch of tradition or simply want windows that are easy to maintain and install, double hung windows are an excellent choice for any construction or renovation project.
Energy Efficiency and Certification
When it comes to energy efficiency, double hung windows are engineered to help homeowners save on energy costs while maintaining a comfortable indoor environment. Modern double hung windows often feature advanced technologies such as low-E coatings, insulated glass, and argon gas fills, all designed to minimize heat transfer and regulate indoor temperatures. These features help reduce solar heat gain, keeping your living space cooler in the summer and warmer in the winter.
Many double hung windows are Energy Star certified, meaning they meet or exceed strict energy efficiency standards set by the U.S. Environmental Protection Agency. By choosing Energy Star certified hung windows, homeowners can enjoy lower utility bills, reduced environmental impact, and a more comfortable home year-round. The use of low-E coatings not only improves energy efficiency but also helps protect your furniture and flooring from fading by blocking harmful UV rays.
With their energy efficient design and high-performance glass, double hung windows are an excellent choice for anyone looking to enhance the comfort and sustainability of their home. Whether you’re building new or upgrading existing windows, investing in energy efficient double hung windows is a smart move for both your wallet and the environment.
What is the difference between a double-hung window and a casement window?
The primary difference is in their operation.
Double-hung windows have two sashes that slide vertically, allowing you to open the window from the top, bottom, or both for versatile air circulation.
Casement windows are hinged on the side and swing outward like a door, providing maximum, uninterrupted ventilation when fully open.
In terms of performance, casement windows generally create a tighter seal when closed due to their compression seal mechanism, offering slightly superior energy efficiency.
How much does it cost to replace a double-hung window?
The total replacement cost varies widely based on size, frame material, glass options, and local labor rates. While professional installation costs are separate, you can achieve significant savings by purchasing directly from the manufacturer. As a reference, a standard-sized aluminum double-hung window from Grandsea starts at approximately $300. We recommend contacting us for a precise quote based on your project’s specific requirements.
