How We Test Double-Hung Windows

At ENGGIA, we rigorously test our awning windows to ensure they meet the highest standards of performance and durability. Our comprehensive testing process includes evaluating air infiltration resistance (ASTM E283), water penetration resistance (ASTM E331), and structural load performance (ASTM E330). These tests confirm that our windows provide excellent insulation, prevent water leaks, and withstand various environmental pressures, ensuring long-lasting reliability and comfort in your space.

What is a hung window?

A hung window features one or two movable sashes that slide vertically within the frame. Single-hung windows have a fixed top sash and a movable bottom sash, while double-hung windows have both sashes operable.
What is the difference between single-hung and double-hung windows?

The primary difference lies in the operability of the sashes. Single-hung windows allow only the bottom sash to move, whereas double-hung windows enable both top and bottom sashes to open, offering enhanced ventilation and easier cleaning.
Are hung windows energy-efficient?

Yes, especially single-hung windows, which have fewer moving parts, reducing potential air leakage. Double-hung windows can also be energy-efficient when properly sealed and equipped with energy-efficient glass options.
How do I clean hung windows?

Many double-hung windows feature tilt-in sashes, allowing you to clean both sides of the glass from inside your home. Single-hung windows may require exterior access to clean the fixed top sash.
Where are hung windows commonly used?

Hung windows are versatile and suitable for various architectural styles. They are commonly installed in bedrooms, living rooms, and other areas where vertical space is available and ventilation is desired.
Do hung windows provide good ventilation?

Double-hung windows offer superior ventilation, as both sashes can be opened to allow air flow from the top and bottom. Single-hung windows provide ventilation through the bottom sash only.
