For many years, Sierra Pacific was the hottest brand in the West. Now, we’re one of the biggest and best window companies in the world. We have all the styles, features, and curb appeal you could ask for. We make dozens of different windows and doors, in thousands of different sizes, shapes and operating styles. Our product lines range from totally custom expansive windowscapes, to high quality windows that provide high performance. We’ll make just about anything you want, and craft it with as much care and attention as if we were installing it in our own home. We have 3 strategically located manufacturing plants to deliver your order when and where you need it. In fact, our windows are proudly installed in 30 countries around the globe. When you consider our commitment to the environment, we think you’ll feel very good about purchasing Sierra Pacific Windows and Doors. Our seed-to-window approach to construction is made possible by our parent company, Sierra Pacific Industries, which owns 1.9 million acres of forestland in California and Washington State. This allows us to insist on “sustained yield” forest management and timber harvesting from our wood supplier, us. It’s working so well, in the midst of supplying select wood stock for Sierra Pacific premium windows and doors SPI will nearly triple the amount of wood growing on its lands in the next 100 years. Additionally, Sierra Pacific is the only window company that maintains continuous quality control from the moment our tree seedlings are planted until our beautiful wood windows are produced, approved and delivered to you.
