What are the benefits of spray foam insulation?
Spray foam insulation offers significant advantages, including superior energy efficiency and enhanced comfort in homes. Its unique properties help reduce energy costs and improve indoor air quality.
Superior air sealing
Spray foam insulation provides an exceptional air seal, minimizing air leaks that can lead to energy loss. This tight seal prevents drafts and helps maintain a consistent indoor temperature, which is crucial for comfort and energy savings.
When installed correctly, spray foam expands to fill gaps and cracks, ensuring that even the smallest openings are sealed. This characteristic makes it an ideal choice for attics, basements, and other areas prone to air infiltration.
High R-value per inch
One of the standout features of spray foam insulation is its high R-value per inch, which typically ranges from 6 to 7. This means it provides excellent thermal resistance with less material compared to traditional insulation types.
Due to its superior R-value, homeowners can achieve better insulation performance in tighter spaces, making it a practical choice for renovations or new constructions where maximizing energy efficiency is a priority.
Moisture resistance
Spray foam insulation is inherently moisture-resistant, which helps prevent mold growth and structural damage caused by water infiltration. Its closed-cell variant is particularly effective in areas with high humidity or potential water exposure.
By acting as a barrier against moisture, spray foam insulation not only protects the building envelope but also contributes to healthier indoor air quality. This is especially beneficial in climates where humidity levels are a concern.
How does insulation impact energy efficiency ratings?
Insulation significantly enhances energy efficiency ratings by reducing heat transfer, which leads to lower energy consumption for heating and cooling. Better insulation results in improved ratings on energy efficiency scales, reflecting a building’s overall performance and sustainability.
