Window Sills Quantity Takeoff Calculator
Prepared By: Parag Kamlakar Pal – Owner of www.civilnotess.com
Detailed Calculation
To determine the total quantity of window sills required, follow these steps:
- Identify the Parameters:
- Window Width (W): The horizontal dimension of the window.
- Sill Width (SW): The horizontal dimension of the sill.
- Number of Windows (N): The total number of windows requiring sills.
- Calculation Formula:
- Sill Length (L): This is the same as the window width.
L = W - Sill Area (A):
A = L × SW - Total Sill Area for All Windows (TA):
TA = A × N
- Sill Length (L): This is the same as the window width.
- Example Calculation:
- Window Width (W) = 1.5 meters
- Sill Width (SW) = 0.3 meters
- Number of Windows (N) = 10
- Sill Length (L):
L = 1.5 meters - Sill Area (A):
A = 1.5 × 0.3 = 0.45 square meters - Total Sill Area (TA):
TA = 0.45 × 10 = 4.5 square meters
Calculator
Total Sill Area: 0 square meters
function calculateSills() {
// Get input values
const windowWidth = parseFloat(document.getElementById(‘windowWidth’).value);
const sillWidth = parseFloat(document.getElementById(‘sillWidth’).value);
const numWindows = parseInt(document.getElementById(‘numWindows’).value);
// Validate inputs
if (isNaN(windowWidth) || isNaN(sillWidth) || isNaN(numWindows) || windowWidth <= 0 || sillWidth <= 0 || numWindows <= 0) {
alert('Please enter valid positive numbers for all fields.');
return;
}
// Calculate sill area
const sillArea = windowWidth * sillWidth;
const totalSillArea = sillArea * numWindows;
// Display result
document.getElementById('totalSillArea').textContent = totalSillArea.toFixed(2);
}
