Retrofit Wall Insulation Calculator
Enter the total floor area of your home in square metres to calculate an estimated cost for wall insulation.
This estimate is based on installing CosyWall Insulation at an installed R-Value of R2.2.
function calculateEstimate() {
const floorArea = parseFloat(document.getElementById('totalArea').value);
if (!floorArea || floorArea <= 0) { document.getElementById('results').textContent = 'Please enter a valid floor area.'; document.getElementById('resultsSection').style.display = 'block'; return; } // Calculate the perimeter based on a square shape and derive the wall area const perimeter = Math.sqrt(floorArea) * 4; // Assume square house const wallArea = perimeter * 2.4; // Fixed wall height (2.4m) const estimate = wallArea * 50; // Cost per m² // Display results document.getElementById('results').textContent = `Estimated Cost: $${estimate.toFixed(2)}`; document.getElementById('calculationSection').style.display = 'none'; document.getElementById('resultsSection').style.display = 'block'; } function resetCalculator() { document.getElementById('totalArea').value = ''; // Clear input document.getElementById('calculationSection').style.display = 'block'; document.getElementById('resultsSection').style.display = 'none'; // Hide results section }
