Best Window Features for Area With Hot Climate
Choosing the Right Window Frames
The window frame type you choose will significantly affect the level of energy efficiency you can expect from your new replacement windows in our extreme southwestern temperatures. Frames for energy-efficient windows can be constructed of one of various highly durable and appealing materials, including wood, aluminum, or vinyl.
Wood and vinyl window frames offer the highest performance in energy efficiency. Wood is higher in cost than vinyl. Vinyl frames have become increasingly popular due to their affordability and excellent energy efficiency.
Performance Ratings of Windows
The performance of the glass is obviously fundamental to the quality of a window designed for energy efficiency. These three efficiency factors determine the effectiveness of the glass panels in energy-saving windows:
- Visible Transmission (VT) — Amount of solar light being transferred through the glass
- Solar Heat Gain Coefficient (SHGC) — Amount of solar heat being transferred through the glass
- U-Value — Amount of heat emanating through the glass by convection, conduction, and radiation.
High-VT glass permits a lot of natural light to enter the home throughout the day, which saves energy use by reducing the need for electrical lighting during daylight hours. The glass’s VT value, recommended by energy efficiency experts, is about 60% to 80%.
For the hottest climate regions, such as the Arizona desert, SHGC should ideally be as low as can be achieved with energy-efficient windows and doors. Window glass providing low SHGC allows only a smaller amount of heat from the sun to enter the home through windows, thereby saving on HVAC costs for air conditioning. An SHGC of under 0.4 is optimum for homes in hot climates, as in the Sonoran Desert, and glass with a low U value is suggested for residential window applications in all climate types to optimize energy efficiency.
Energy Star Certified Windows
To earn the ENERGY STAR label, windows must meet certain performance criteria, which include U-factor, solar heat gain coefficient (SHGC), and air leakage ratings. These windows are designed to meet stringent energy efficiency guidelines set by the U.S. Environmental Protection Agency (EPA).
Energy Star Certified Windows meet strict standards for energy efficiency and are an excellent choice for homeowners living in hot climates like the Arizona desert and offer several benefits, including reduced energy costs, improved indoor comfort, and increased energy efficiency. These windows are made of high-quality glass and frames that are specifically designed to block solar heat gain and enhance insulation, so you can keep your home cool and comfortable without relying too heavily on your air conditioning system. By installing Energy-Star certified windows, you can significantly reduce your carbon footprint and contribute to a healthier environment while saving money on energy bills.
Double-Pane and Triple-Pane Windows
Today’s triple-pane or double-pane windows are the most highly recommended for maximum energy efficiency in virtually all climate zones. The insular space between the window panes saves energy and helps reduce electricity costs.
For significantly enhanced efficiency, argon, krypton, and other gases are utilized between glass panes as insulators. Such gases are denser than air, so they provide more effective insulation and better window energy saving.
Argon is the most popular gas for filling double-pane energy-efficient windows because it is a highly efficient insulator and costs considerably less than krypton gas. Krypton is used in narrower spaces between triple glass panes. It is a more scarce gas and much higher in price than argon.
Low-E Window Glass for Energy Efficiency
Low emissive, known as Low-E glass, is used to increase the energy efficiency of windows and doors. This glass is coated with a layer of metallic oxide material, which helps prevent the transfer of heat between the glass panes. Low emissive glass minimizes heat penetrating through windows in the southwest region's most efficient windows manufactured for the desert climate. So, when choosing windows, be aware of their NFRC rating.
Warm Spacers
Warm spacers are a vital component in energy-efficient windows for hot climates like Arizona. They minimize heat transfer through the window, providing consistent temperatures and reduced energy consumption. Energy Shield Window & Door Company incorporates warm spacers into our window designs to ensure top-quality products tailored for hot climates.
These spacers separate glass panes in double or triple-glazed windows, creating an insulating barrier that keeps heat out during summer and retains warmth in cooler months. Homeowners enjoy increased comfort and lower energy bills year-round. Our windows address heat reflection, dust control, and noise reduction for optimal performance in hot climate regions.
Upgrade your home with Energy Shield Window & Door Company's high-performance windows featuring warm spacers for unparalleled comfort and energy savings.

Energy-efficient windows have a significant impact on utility bills in hot climates due to their ability to regulate indoor temperatures and minimize heat transfer. Here's how they contribute to lower energy costs:
Improved Insulation: Energy-efficient windows are designed with multiple glass panes, low-emissivity (Low-E) coatings, and insulating gases like argon or krypton between the panes. These features work together to reduce heat transfer, keeping your home cooler during hot summer months and reducing the need for air conditioning.
Solar Heat Gain Reduction: Low-E coatings on energy-efficient windows reflect a portion of the sun's heat away from your home while allowing natural light in. This reduces solar heat gain inside your house, decreasing the demand for air conditioning and lowering energy consumption.
Airtight Seals: High-quality energy-efficient windows have tight seals that prevent air leaks between the window frame and glass panes or around the window unit itself. This reduces drafts and improves insulation, which helps maintain a stable indoor temperature without overworking your HVAC system.
Reduced HVAC Load: As a result of improved insulation, reduced solar heat gain, and minimized air leakage, energy-efficient windows lessen the workload on your HVAC system. This leads to lower energy consumption and extended lifespan for your heating and cooling equipment.
By investing in energy-efficient windows for homes in hot climates, homeowners can experience significant savings on their utility bills due to reduced reliance on air conditioning systems while maintaining comfortable indoor temperatures throughout the year.
