When designing a space, window placement, and design are essential in determining the environment of a home. A window brings in the comfort of the outdoors, illuminating living spaces with sunlight. What is often overlooked however is the performance of the unit’s glazing, as the energy and thermal performance of windows will have a great impact on the comfort and experience received within the home.

Understanding Optimal Window Placement

As the sun beams throughout the day, the sunlight shines through the four faces of a home with different strengths.

The south side of a home receives the most direct sunlight, reducing the use of artificial light within the home and passively heating a dark room. In the summer, however, these windows can provide an excess amount of heat and may need additional glazing to prevent a temperature imbalance.

Having north-facing windows comes with certain advantages. Being the surface wall that receives the least amount of sunlight, north-facing windows can provide a lower heat gain during the warmer seasons, resulting in a uniform amount of light received within the home.

Eastern and western orientation windows receive direct light in the early morning or afternoon. Having sunlit rooms throughout the day can provide a sense of comfort, providing sun-soaked living spaces within seating areas, office rooms, and bedrooms. Direct sunshine exposure has many benefits, but may also result in overheating spaces without controlled solar heat gain protection and shading to minimize additional energy consumption.

Window Technologies for Improved Thermal Performance

Considering the energy and thermal performance of window units is also essential in understanding the impact that windows have in a home. Oftentimes window surface area can be disproportionate to the energy consumption produced by the enclosure. It is important to factor in the U-value (rate of heat transfer through a window) and the solar heat gain coefficient (SHGC).

If there is a desire for visible light to enter the space but to regulate the temperature within a home as well, using low-emissivity coatings (Low-E) as glazing on windows will minimize heat transfer. Similarly, multiple glazing (double or triple) can reduce heat loss to maintain the regulated temperature within the home during all seasons.

In Windsor windows and doors, the Low-E glass is coated with anti-reflective metal oxide, rejecting sunlight in the summer and bringing rays of heat into the home during winter-time. While also regulating temperature conditions, the non-direct UV exposure protects furniture, paintings, and carpets from fading.

LoE 366 is a double-paned insulated glass filled with argon. With a triple layer of silver between the two panes, this glass is able to provide high solar control while also maintaining great visibility.

Low emissivity Cardinal i89 coating is painted inside what is called Dual Low-E glass. This coating provides insulation that is of higher performance than clear and standard Low-E insulated glass. Windsor products use a double-strength glass as standard seen in the Pinnacle, Legend, and Next Dimension lines. Double-strength glass provides two times the thickness of single strength, creating a stronger obstruction to heat transfer within the home. The glazing system used within a window will ultimately determine how well it is able to redistribute light and transform it into a comfortable and lively home.

If there is a desire for visible light to enter the space but to regulate the temperature within a home as well, using low-emissivity coatings (Low-E) as glazing on windows will minimize heat transfer. Similarly, multiple glazing (double or triple) can reduce heat loss to maintain the regulated temperature within the home during all seasons.

Windsor’s Glazing System leverages the energy performance of Super Spacer® Warm Edge Technology along with Cardinal LoE coated panes and sheet glass. By integrating Super Spacer® technology, which minimizes heat transfer and reduces condensation, our Insulating Glass (IG) solutions offer exceptional thermal efficiency. This advanced technology not only enhances energy performance but also contributes to the overall comfort and sustainability of your living spaces.

Optimizing light in your home through strategic window placement and advanced window technologies is crucial for enhancing both comfort and energy efficiency. Understanding the impact of sunlight on different orientations of your home allows for thoughtful consideration in selecting the right glazing options to regulate temperature and minimize energy consumption.
