Able Glass, Window & Door has been installing windows and doors in all types of residential and commercial (apartment) buildings since 1969. Over the years we have seen many different types of windows, window systems, and installation methods come and go. Window trends appear with the different types of construction, architecture, and consumer tastes as well as the ever changing rules of the industry standards to ensure that a building is energy efficient. Window design and construction has gradually improved with technological advances in making a building use less energy, which helps reduce energy costs. Today, in the San Francisco Bay Area housing market, we are experiencing some new trends in the types of windows being constructed and installed primarily for residential rental and investment properties by professional property management companies. These trends continue to develop and evolve but here is an outline of what we are seeing in today’s environment.
