Popular Windows in Redwood City

Vinyl replacement windows are currently the most popular windows in Redwood City. In the last few years materials like Andersen's fibrex and Milgard's fiberglass windows have become available giving home owners more options. Because of the great weather we have in San Mateo county compared to the rest of the country we are fortunate to not have to use expensive wood windows and storm windows and doors that are a must in the mid west. The most popular windows today are vinyl replacement windows as they perform close to wood windows at a fraction of the cost. The main key in purchasing vinyl windows is to make sure the window has a substantial amount of frame material (vinyl) as this is extremely important to the longevity of the window.

Insulated Low-E window Glass Treatments

Low-emissivity (Low-E) glass is window glass that has been treated with an invisible silver oxide metallic coating that creates a surface that reflects heat back to its source. Windows treated with Low-E coatings are proven to reduce energy consumption, decrease fading of fabrics,furniture,shutters,window coverings , window treatments and flooring by blocking between 84% to 95% of (UV) ultraviolet rays and increase overall comfort in your home. The heat that passes through your window glass is measured by the U-factor. The lower the U-factor the more energy-efficient your glass is. This type of light is produced by the sun and generates heat in your home. Too much of this heat, especially during summer can cause undesirable heat gain . Low-E glass reduces the amount of ultraviolet light that enters your home, with a minimal reduction invisible light. Conversely, in winter, Low-E glass reflects the heat from the inside lost through your windows back to the inside of your home, keeping heating costs down. Depending on your home's heating and cooling needs, we can help you choose the right type of Low-E glass to suit your needs.
