R-Value and Insulation Effectiveness
The R-value of insulation measures its resistance to heat flow. The higher the R-value, the better the insulation’s ability to prevent heat transfer. The recommended R-value for insulation varies depending on the climate and the specific area of your home. For example, attics in colder climates typically require higher R-values than those in warmer climates.
R-value is a measure of insulation’s resistance to heat flow. Higher R-value indicates better insulation.
Air Sealing
Air sealing is the process of sealing gaps and cracks in your home’s envelope to prevent air leakage. Air leaks can significantly impact your home’s energy efficiency, leading to higher heating and cooling costs. Air sealing is a relatively simple and cost-effective way to improve your home’s energy performance.
Tips for Air Sealing
- Inspect your windows and doors for drafts: Use a piece of paper or a lit candle to check for drafts around windows and doors. Seal any gaps or cracks with weather stripping or caulk.
