Size siding, windows, doors, house wrap, and exterior finishes for your home's envelope. A tight, well-sealed exterior is the first line of defense against weather and energy loss — these calculators help you get accurate quantities for every component.
Quick Tips
- Add 10% waste for lap siding and up to 15% for diagonal or staggered patterns.
- Always install house wrap with shingle-style laps (upper course over lower) to shed water properly.
- Check window U-values and SHGC ratings for your climate zone before purchasing — wrong specs waste energy for years.
