Protecting History with UV Blocking Window Film

October 5, 2011 | 2 comments

The preservation of historic buildings is fundamental to protecting a nation’s culture, and in 1966, Congress founded the National Historic Preservation Act (NHPA) authorizing the public use of historic buildings. To preserve the inside of aged structures, interior designers and preservation architects should explore ways to increase energy efficiency and provide interior protection that does not alter the exterior look of the long-standing landmark.

Window films can help to preserve historic structures in two main ways: first, by maintaining the original wooden window frame instead of having replacement windows installed for energy efficiency, and second, by helping to protect the interior from the harmful effects of UV rays.

Maintains Authenticity 

Many preservation architects across the country are attempting to increase energy efficiency by installing new windows. However, repairing and maintaining the original windows is often a more sustainable option. By utilizing a solution like commercial window tint, preservation architects can lower energy costs while keeping the original wooden casings, preserving historical authenticity.

Case Study: Scott Country Society Historical Home in MN

Scott County Society Historical Home is a professional institution housing historical resources of Scott County. With a collection of important artifacts needing to be preserved, the curator needed a way to slow the rate of deterioration caused by damaging UV rays, while also maintaining the building’s authenticity. She contacted a window film dealer who installed UV blocking window film to reduce the damage and fading of interiors. After the installation, the interior artifacts were shielded from solar heat and damaging rays.

Helps Protect Building Interiors

The sun’s UV rays are one of the causes of premature fading interior furnishings and flooring. Commercial window tint can help protect occupants and interiors from these damaging effects. The window tint does not alter the view of the outside world and allows plenty of natural sunlight to shine through, making it a cost effective way to help protect historic interiors and artifacts.

Case study: House of Seven Gables in Salem, MA.

As the oldest mansion in New England, House of Seven Gables is listed on the register for National Historic Treasures. With energy costs at a steady rise, the Director of Preservation and Collection Care for Seven Gables, Alexandria Mason, needed a solution that would help both lower her costs and preserve her interior. The auditors recommended the installation of UV blocking window film. After installation, the Director of Preservation reported a reduction in energy costs and peace of mind knowing that 99.9% of UV rays were being blocked by the window film..

Other Options for Updating Original Windows 

In conjunction with window film, other minor updates can help preserve a building’s interior and lower energy costs without altering authenticity.

Weather Stripping: This is a quick and inexpensive way to increase a building’s energy efficiency by as much as 50 percent.

Weather stripping and commercial window tint are just two ways to help protect interiors. Learn more about finding the right UV blocking window film and starting a preservation retrofit project with Vista™ Window Film.
