Built on Tradition, Designed for the Future: Windows & Doors Since 1986
Company History
Primeline Windows & Doors was founded in 1986 with a vision to lead the Canadian market in providing high-quality custom-engineered aluminum windows and doors. From the very beginning, Primeline focused on offering custom solutions for both residential and commercial projects, quickly establishing a reputation for craftsmanship and technical expertise.
In May 2024, Primeline was acquired by Triumph Group of Companies, expanding its offerings to include full building envelope solutions. The acquisition enables Primeline to scale its services while maintaining its legacy of craftsmanship and customer focus.
Today, with manufacturing facilities in Etobicoke, Ontario, Primeline continues to serve both the residential and ICI markets, delivering innovative, custom-designed systems. Despite the scale of the acquisition, Primeline maintains its commitment to handcrafted precision, delivering quality, service, and performance to every project.
