How to Choose Window Spring Balances

• Window Type

Choose a balance that is compatible with the window type. For example, a double-hung balance is suitable for double-hung windows, while a single-hung balance is suitable for single-hung windows.

• Window Material

The window material affects the balance's performance and lifespan. For heavy windows, choose a balance made of durable materials like steel. Steel balances are strong and long-lasting. They are suitable for heavy windows. For light and medium-weight windows, a balance with a steel coil can work. The coil balances are suitable for average-weight windows. They are durable and provide good support.

Aluminum balances are a good choice for lightweight windows. They are light and won't put pressure on the frame. The aluminum balances are suitable for light aluminum windows. They won't damage the frame. Lead balances provide strong support for heavy windows. They offer a good lifting capacity.

• Weight Capacity

Determine the window's weight and select a balance that can support it. Choose a balance with a higher weight capacity than the window's weight. This ensures the balance can lift the window easily. It also prevents overloading, which can damage the balance.

• Adjustability

Some balances are adjustable. They can fit windows of different sizes. If installing various-sized windows, choose an adjustable balance. This provides flexibility during installation.

• Balance Length

Choose a balance with a length equal to the window's height. This ensures the balance can support the entire window. If the balance is too short, the window may not open fully. Select a longer balance if the window opening is taller than average.

• Quality and Durability

Consider the balance's quality to ensure it is long-lasting. A well-made balance provides years of service with minimal problems. Check the balance's construction materials. Strong materials like stainless steel offer durability. They resist rust and corrosion.
