Frequently Asked Questions
Energy-efficient windows reduce heat transfer, keeping your home cooler in the summer and warmer in the winter, leading to lower energy bills. They also block harmful UV rays, protecting your furniture and improving indoor air quality. In Los Angeles, this can significantly reduce your reliance on air conditioning.
Consider the window's U-factor (insulation), Solar Heat Gain Coefficient (SHGC), and Visible Transmittance (VT). Lower U-factors and SHGC values are ideal for reducing heat gain in sunny climates like Los Angeles. Also, think about the style of your home and choose windows that complement its architecture while maximizing energy efficiency.
The process begins with measuring the window openings and ordering the correct size. The old window is then carefully removed, the opening is prepared, and the new window is installed and sealed. Finally, insulation and trim are added for a weather-tight finish. Professional installation ensures optimal performance and longevity.
