Shgc for the french doors.
Solar heat gain coefficient measures how well a product can resist unwanted direct or indirect solar radiation.
This tool provides some of the most common options on windows and doors and related nfrc certified values.
Glazed doors in hot or temperate climates should have a low shgc.
The lower the coefficient the better the glazed door is at blocking the sun s heat.
Energy performance data for select combinations of options is available in table format on each product page.
This radiation can cause your home to heat regardless of outside temperature which.
The lower the shgc the less solar heat it transmits and the greater its shading ability.
Solar heat gain coefficient shgc is the fraction of solar radiation admitted through a window door or skylight either transmitted directly and or absorbed and subsequently released as heat inside a home.
The circled value shows you the rating a door has received.
For both measurements lower numbers equate to higher energy efficiency.
South facing glazed doors in cold climates should have a high shgc.
Each rating is split into two values.

The second is the solar heat gain coefficient shgc which is the amount of solar radiation that transfers through the window.
The milgard energy calculator provides a quick and easy way to help you select windows and doors that can meet local energy codes and project requirements.
