About Insulation Calculator
Calculate insulation needed for your space. Enter your measurements to get an accurate estimate of materials needed for your project.
Understanding R-Value
- R-Value: Measures insulation's resistance to heat flow
- Higher = Better: Higher R-values provide better insulation
- Climate Zones: Colder climates need higher R-values
- Coverage: Standard roll covers 40-50 sq ft
Recommended R-Values by Location
- Attic: R-30 to R-60 depending on climate
- Walls: R-13 to R-21 for most climates
- Floors: R-13 to R-30 over unheated spaces
- Basement: R-10 to R-15 for walls
Frequently Asked Questions
What R-value do I need?
It depends on your climate and location. Northern climates need R-49 to R-60 in attics, while southern climates need R-30 to R-49. Check local building codes for requirements.
Can I layer insulation to increase R-value?
Yes, R-values are additive. You can layer different insulation types. For example, R-19 + R-11 = R-30 total.
How many square feet does a roll of insulation cover?
Standard rolls cover 40-50 square feet depending on width and thickness. Check the product packaging for exact coverage.
