Core performance factors for our climate For our heat and humidity, start by targeting a strong U-factor and an SHGC tuned for sun control, which depend on the low-E glass stack. A lower U-factor slows heat flow into the house, which keeps rooms cooler. The SHGC needs to be low enough to block solar gain, or the AC will fight the afternoon sun every day. Low-E coatings are not all the same, and the right stack will block infrared heat without darkening the room. Fill between panes with argon and use warm-edge spacers to keep the glass perimeter from becoming a hot spot. Select frames that do not swell or rot; vinyl and fiberglass are reliable in South Louisiana humidity.

Fiberglass frames are dimensionally stable in heat and accept paint if you want a custom color later, with slightly higher upfront cost.

Storm resilience and insurance benefits Impact-resistant windows for hurricane season Mandeville Louisiana use laminated glass that stays intact even if cracked, which protects the building envelope and can help with insurance discounts. Check the DP rating and water test results to match your site’s wind zone and rain events. The install is as crucial as the glass: stainless anchors, continuous sealant, head flashing, and a drained sill keep wind and water from finding a path inside.

Reading the label for our zone Choose units qualified for the Southern zone, where lower SHGC is prioritized to beat the sun without sacrificing winter comfort. Avoid heavy tints that kill natural light; modern low-E does the heat-blocking work more cleanly.
