Window and Door
Marvin Replacement windows and doors offer several energy efficient options that work best for your region.
Home energy efficiency
According to the National Fenestration Rating Council, the average American household spends $1,500-$2,500 on energy bills every year; 45% of that cost is for heating and cooling. Tax credit programs change often. To find the latest updates, visit the ENERGY STAR website. Here is a link to the Marvin Manufacturers' Certification Statement.
Here’s what to look for when choosing energy efficient windows.
Glass coatings play an important role in a home’s energy efficiency. Different climates require specific glass coatings to perform the best. Marvin Replacement windows have four glass coating options: Low E1, Low E2, Low E3, and Low E3/ERS. Low E1 coating works well in colder climates because it allows more heat into a home while Low E3 works well in warmer climates because it can reject solar heat.
Efficiency in all climates
Your climate matters when deciding on energy efficient windows. Marvin Replacement’s Low E2 glass is 56% more efficient in summer and 49% more energy efficient in the winter. Furthermore, Low E3 glass is 70% more energy efficient in summer and 49% more energy efficient in winter.*
