Calculator - Construction materials

A ready-made calculator built on the MegaCalculator module — designed for construction, insulation, and soundproofing materials.

It helps customers instantly calculate how much material they need for a specific area — or, conversely, determine the total area based on the quantity selected.

This calculator is ideal for products sold by area, pack, or roll, such as facade and roof insulation, underlays, floor soundproofing, sealing layers, or wall and ceiling protection.

Calculator Features

• Calculates required quantity based on entered area;
• Reverse mode — calculates area from quantity;
• Option to add an extra stock percentage (e.g., +10%);
• Real-time price and quantity updates on the product page;
• Flexible setup for different material types (rolls, boards, sheets).

What You Get

• A preconfigured calculation formula for OpenCart;
• Full installation and integration with your store;
• Ability to adjust design (colors, fonts, layout) without changing core logic.

Example in Use

This calculator is similar to the one used in real projects like insulationgo.co.uk,

where users can simply enter their area, instantly get the result, and optionally add extra stock.

Perfect for online stores selling construction, facade, insulation, or soundproofing materials — simple, accurate, and professional.
