Cooper Historical Windows
Vendor / Manufacturer

The Cooper Group was built on preserving and celebrating traditional craftsmanship that is vastly fading. Our company has 40+ years of practice in historic preservation with experience in dismantling, relocating, and reconstructing, 17th, 18th, and 19th century buildings often slated for demolition. Now the company, Cooper Historical Windows, has a strong focus on preserving historic windows, while upgrading efficiency to ultimately allow historic windows to thrive in today’s world.

Cooper Historical Windows puts equal value on historical accuracy and energy efficiency. With the use of our made in-house Liberty Restoration Glass, we are able to produce period accurate, high-performance IGUs tailored for any historic application, reaching R-values as high as 10.4. We will evaluate a project and select an appropriate sequence to control how the IGU performs and directionally tune a building with its windows, ultimately saving in energy costs.

When discussing a historic building, the conversation of climate change is inevitable. Sourcing sustainable products, mitigating how much sunlight your window allows into the building and controlling solar heat gain and heat loss are the most important and challenging aspects for designing a window for climate change. Our products combine restoration, conservation, and high-performance technologies to close the demanding gap between energy efficiency and historical accuracy. Cooper Historical Windows represents a means for addressing climate change without jeopardizing the intended aesthetic of a historic window and greatly prolonging the life of historic structures while moving towards a greener future.
