Our Story


In 2002, Abdiel “Abe” Lopez founded SIW Windows and Doors in Palm Beach County. Abe was born in Cuba and came to Florida with his family in 1981. As a young man, he started working in his family’s window business, and for more than ten years he witnessed firsthand the devastating destruction caused by tropical storms and hurricanes. Motivated by the desire to protect property and keep people safe, Abe and his wife Yida created SIW Windows and Doors and started manufacturing high-end impact-resistant windows and doors.

With the SIW Windows and Doors manufacturing facility and showroom located in Delray Beach, SIW quickly built a reputation for crafting beautiful products with a wide range of design options. Most importantly, SIW windows and doors were proven to be durable, able to withstand the harshest weather conditions, and consistently outperformed the competition. Value and unprecedented customer service also contributed to the fast growth of the company.

SIW replaced all the windows [14] in our home with Impact Resistant. They were great in terms of the first contact to the very last. … The installers were very professional, hard-working, and kept the dust that you normally get, to a minimum … Throughout the entire process, the office receptionist kept us informed and was very courteous and professional as well. SIW has our highest recommendation!"
