Door Installation Calculator

This NPM package provides a comprehensive solution for calculating the necessary materials for door installations, specifically tailored for both bi-fold and pre-hung doors. It includes calculations for frame and casing dimensions, material requirements, and checks for fitting within rough openings.

Features

• Calculate frame dimensions for bi-fold or pre-hung doors.
• Determine casing cut lengths based on door type.
• Check if a door fits in a specified rough opening.
• Suggest adjustments or special-sized doors if necessary.
• Calculate and round up material lengths for order based on standard lumber sizes.

Installation

Install via npm:

npm install door-frame-calc

Usage

Here is a quick example to get you started:

const DoorInstallationCalculator = require('door-installation-calculator');

const calculator = new DoorInstallationCalculator(
    "bi-fold",  // Door type
    34,         // Rough opening width
    82,         // Rough opening height
    4.5,        // Wall thickness
    0.75,       // Frame thickness
    2.25,       // Casing width
    30,         // Door width
    80          // Door height
);

try {
    const results = calculator.getAllCalculations();
    console.log(results);
} catch (error) {
    console.error("Error:", error.message);
}
