In Pasadena, homeowners experience a wide range of temperatures, from intense summer heat to surprisingly cool winter nights. When planning a residential remodel, windows are often viewed primarily as an aesthetic choice. However, as a general contractor, we view windows as a critical component of your home's "thermal envelope."
At Everlasting Construction & Design, we prioritize energy-efficient upgrades that reduce your long-term utility costs and improve year-round comfort. Upgrading from old single-pane windows to modern high-performance units is one of the most effective ways to modernize your property's efficiency.
Understanding the Performance Metrics
When selecting windows, you will encounter a variety of technical ratings. Understanding these two key metrics is essential for choosing the right product for a California climate:
1. U-Factor (The Insulation Rating)
The U-factor measures how well a window prevents heat from escaping your home. The lower the U-factor, the better the window's insulating properties. In Southern California, a low U-factor keeps your home warmer during winter nights and cooler during the day.
2. SHGC (Solar Heat Gain Coefficient)
SHGC measures how much solar radiation (heat from the sun) enters your home through the glass. In sun-drenched areas like Pasadena, a low SHGC is vital. It blocks the heat energy that typically forces your air conditioning system to work overtime during the summer.
The Benefits of Low-E Coatings
Modern high-performance windows utilize "Low-E" (Low Emissivity) coatings. This is a microscopically thin, transparent layer of metal or metallic oxide deposited directly on the glass surface. This coating reflects long-wave infrared energy (heat), keeping it inside in the winter and outside in the summer, all while allowing natural visible light to pass through.
National Energy Standards
To ensure you are selecting products that meet the highest federal standards for efficiency, we always recommend looking for the Energy Star label. These certifications are verified through rigorous independent testing and can often qualify homeowners for significant tax credits and local utility rebates.

Even the most expensive, highly-rated window will fail if it is improperly installed. As general contractors, we focus on the "flashing" and "sealing" of the window unit. We ensure that the window is perfectly plumb and level, and that high-quality weather-resistant barriers (WRB) are integrated with the siding to prevent both air infiltration and water leaks.
By combining top-tier window technology with expert structural installation, Everlasting Contractor helps you create a more sustainable, comfortable, and energy-efficient home.
