4 Elements of an Energy-Efficient Entry Door

Your doors aren’t just openings you walk through every day. They’re also lovely design elements that define the look of your home and barriers that protect you and your interiors from harsh weather and security threats. Most importantly, your doors are great contributors to comfortable and energy-efficient living spaces.

In this post, your trusted home improvement contractor for quality entry doors in Milwaukee, Renewal by Andersen®, discusses the components that make up an energy-efficient door unit.

1. Air Leakage

The National Fenestration Rating Council (NFRC) manages a voluntary program that tests, measures, and labels products, including replacement doors according to their energy performance ratings. This provides a reliable way to determine a door’s energy properties. One of these is air leakage, which rates the air movement around the door. A unit with low air leakage means that it has a tighter seal.

The material used for these doors affect this rating. For instance, Renewal by Andersen® of Milwaukee carries ProVia® entry doors that offer superior insulating properties because it’s made of 43 percent thicker fiberglass. Its dual perimeter seal also prevents costly energy from leaking out of your home, resulting in lowered heating and cooling bills.

2. U-Factor

This rates how a glass door conducts non-solar heat flow. The lower the U-factor, the better the unit’s resistance to heat flow. Our selection of ProVia fiberglass entry doors provides a U-factor of 0.10, the lowest recorded measurement for heat conduction for entry doors in the U.S. This also keeps out uncomfortable temperatures in your home through its custom bottom sweep.

3. Visible Transmittance

This measures the visible transmission (VT) of sunlight through a glass door. A unit with high VT relays light that is more visible. This rating will depend on your home’s daylight requirements, as well as your need to reduce interior glare inside your rooms.

4. Solar Heat Gain Coefficient

You’ll want your glass doors in Milwaukee to use solar heat to best effect, based on your area’s climate and home design. Solar Heat Gain Coefficient (SHGC) measures the solar radiation admitted inside your home. A lower SHGC means lesser solar heat transmission, reducing cooling loads in summer by blocking heat from the sun. A door with higher SHGC can effectively collect solar heat during the winter, keeping your rooms warm without turning up the thermostat.

Renewal by Andersen® of Milwaukee’s patio doors has optional glass that can filter harsh UV light, which can subject your interiors to sun damage. This can also block IR light, reducing heat radiation and maintaining a pleasant indoor temperature inside your home.
