ARTICLE NO.80|Determining the appropriate weight capacity for friction stay hinges based on the weight of your window sash
Determining the appropriate weight capacity for friction stay hinges based on the weight of your window sash is an important consideration to ensure the long-term performance and safety of your windows. Here's a guide on how to do this:
## Calculating the Window Sash Weight
1. **Measure the Window Sash Dimensions**: Start by measuring the width, height, and thickness of your window sash. This will give you the dimensions needed to calculate the weight.
2. **Determine the Sash Material**: Identify the material used for your window sash, as this will affect the weight calculation. Common materials include wood, aluminum, and vinyl.
3. **Calculate the Sash Weight**: Use the following formula to calculate the approximate weight of your window sash:
Weight (lbs) = Width (in) x Height (in) x Thickness (in) x Material Density (lbs/in³)
Material Density (approximate):
- Wood: 0.5 lbs/in³
- Aluminum: 0.1 lbs/in³
- Vinyl: 0.05 lbs/in³
For example, a wooden window sash measuring 36 inches wide, 24 inches high, and 1 inch thick would have an approximate weight of:
36 in x 24 in x 1 in x 0.5 lbs/in³ = 432 lbs
## Selecting the Appropriate Hinge Weight Capacity
Once you have calculated the weight of your window sash, you can use this information to select the appropriate friction stay hinges with the correct weight capacity.
As a general guideline:
- For windows up to 100 lbs, look for friction stay hinges with a weight capacity of at least 50 lbs per pair.
- For windows between 100-200 lbs, choose hinges with a weight capacity of at least 100 lbs per pair.
- For windows over 200 lbs, opt for friction stay hinges with a weight capacity of at least 150 lbs per pair.
It's important to note that these are just general recommendations. It's always best to consult the hinge manufacturer's specifications or a window hardware specialist to ensure you select the correct weight capacity for your specific window size and sash weight.
By accurately calculating the weight of your window sash and choosing the appropriate friction stay hinges, you can ensure the safe and reliable operation of your casement or aluminum windows.
