Features that Make a Patio Door Energy-Efficient

Energy-efficient windows and doors are some of the best investments you can make for your home. A high-quality patio door will create a seamless transition between your indoor and outdoor spaces. It will also help prevent energy loss, saving you on heating and cooling costs.

Features of ENERGY STAR Patio Doors

ENERGY STAR patio doors usually feature multi-pane glass in which the spaces are filled with gases or air. Gases such as krypton and argon can boost the glass and the door’s insulation.

Today’s providers of residential window services offer doors made in newer materials like fiberglass, wood cladding, or steel with polyurethane foam core. Moreover, an ENERGY STAR door can help reduce your monthly energy costs and carbon footprint by around 12 percent.

ENERGY STAR® Ratings for Doors

U-Factor – Usually between 0.25 to 1.25, U-factor measures the rate of heat loss. The lower the U-factor of a patio door is, the better.

Solar Heat Gain Coefficient (SHGC) – SHGC refers to how well a patio door can prevent solar heat gain. A patio door with lower SHGC will transmit less heat into your interior.

Glazing Level – The glazing level of a door depends on how much glass is in the unit’s design. A patio door with greater than or a half-lite glass is made of half glass or less. Meanwhile, a unit that’s greater than half-light is mostly glass.
