House Wrap Calculator Pro (USA)
Accurate Material Estimation for US Construction Projects
How to Use This House Wrap Calculator Pro (USA)
This tool helps contractors and DIY homeowners estimate the amount of house wrap (like Tyvek, Typar, or Felt paper) required for a building project. To ensure accuracy, we use standard US measurements and account for necessary waste.
Key Calculation Factors
- Perimeter Calculation: We calculate the total distance around the house (Length + Width) x 2.
- Openings: We automatically deduct standard square footage for windows and doors to prevent over-ordering.
- Waste Factor: House wrap must overlap at seams (usually 6-12 inches) and around corners. Our waste factor slider ensures you buy enough material to cover these overlaps.
Why Waste Factor is Important?
Even on simple houses, you will lose material to cuts and overlaps. A 10% waste factor is standard for rectangular houses. Complex designs with many corners, bump-outs, or multiple stories may require up to 15-20%.
Standard Roll Sizes in USA
Most house wraps come in rolls ranging from 4 to 10 feet in height. The most common size for residential construction is 9 feet tall by 100 feet long, covering 900 square feet.
