How to Improve Home Energy Ratings With New Windows in Mandeville, Louisiana

Essential Window Performance Metrics

If you want a higher home energy rating in Mandeville, Louisiana, start with the windows, since our climate exposes weak frames, poor seals, and heat-sucking glass.

Focus on U-factor for insulation, SHGC for heat rejection, visible transmittance for daylight, and air leakage for drafts.

Choosing the Right Window Features

A low U-factor reduces radiant losses, which supports stable indoor temperatures across seasons.

Given our sun angle and humidity, a lower SHGC keeps living spaces from spiking in temperature during peak sun.

A low air leakage rating helps control indoor humidity and eases AC workloads.
