Sliding Door Quantity Takeoff Calculator
Prepared By: Parag Kamlakar Pal – Owner of www.civilnotess.com
To determine the quantity of materials needed for a sliding door installation, we must calculate the track length and frame material based on the door dimensions and overhang. Below is a numerical example and an interactive calculator to assist with these calculations.
Example Calculation
Assume the following dimensions:
- Door Width (W): 100 cm
- Door Height (H): 200 cm
- Overhang (each side): 5 cm
**Track Length Calculation**:
Track Length = Door Width + 2 × Overhang
Track Length = 100 cm + 2 × 5 cm = 110 cm
**Frame Material Calculation**:
Perimeter = 2 × (Door Width + Door Height)
Perimeter = 2 × (100 cm + 200 cm) = 600 cm
Interactive Calculator
function calculate() {
const width = parseFloat(document.getElementById(‘width’).value);
const height = parseFloat(document.getElementById(‘height’).value);
const overhang = parseFloat(document.getElementById(‘overhang’).value);
if (isNaN(width) || isNaN(height) || isNaN(overhang)) {
alert(‘Please enter valid numbers’);
return;
}
const trackLength = width + 2 * overhang;
const perimeter = 2 * (width + height);
document.getElementById(‘track-length’).textContent = `Track Length: ${trackLength} cm`;
document.getElementById(‘frame-material’).textContent = `Frame Material Required: ${perimeter} cm`;
}
