Preserve Protective Film

When you are done with a new or remodeled house, filthy or scratched windows can take the wind out of the homeowner’s sails. Post-construction cleanup is also an annoyance, as you spend time and money cleaning instead of moving on to the next job.

Cardinal IG Company’s Preserve window film provides an end-to-end solution to dirty and marred windows. Pre-applied on Cardinal insulating glass (IG) units, Preserve film protects everybody’s interests, whether it be the window manufacturer, construction supplier or contractor. Most importantly, it protects your relationship with the homeowner, as they get perfect, clean windows every time.

But spattered paint isn’t the only problem. There’s excess stucco. Slopped mud. Scratched glass. By the time construction is over, the windows are a mess. But if your windows are covered with Preserve, clean-up is a snap. So when the job is over, builders simply peel off Preserve and throw it away – along with all the grime, even the labels.

From IG protection to window perfection.

We at Cardinal and our window manufacturers take great care to ensure that glass leaves factories in perfect condition. However, after it leaves the production facility, glass can be damaged in shipping and handling. What’s more, the job site during construction of a new home can be a battlefield. Glass can easily be scratched or damaged. Yet, customers expect a beautiful home with clean new windows.

Preserve is the clear solution to window protection. This patented film defends your glass. Factory-applied to both the outer and inner surfaces in overlapping layers, it ensures that the entire glass surface is protected.

The fast and furious are not always the careful and cautious.

Construction crews – hard-working, sure. Careful, not always. By the time everyone is finished, the windows are filthy. In addition, labels create “ghosting,” leaving a distracting visual blemish. Cleaning up this mess at the end of the job is a hassle, taking up valuable time and labor. Even worse, damaged glass must be reordered and replaced. Preserve can solve this job-site dilemma.

Because the film is applied at the factory, construction crews do not have to waste time applying and later removing protective coverings such as tapes, films, sprays, etc. Other makeshift fixes like newspaper or cardboard are not ideal either, and they block out light. Preserve is clear, so natural light still shines into the interior of the structure.


Preserve saves you time, money and a lot of hassle.

Without Preserve, glass generally requires at least two heavy-duty cleanings before a job is finished. A recent market research study found that Preserve could save hundreds of dollars per house in cleanup costs. Not exactly pocket change.

With Preserve, you can say goodbye to these time- and money-wasting cleanups. At the end of construction, Preserve peels off in one easy, smooth motion, taking all the accumulated dirt and labels with it. What’s more, clean windows can mean a shorter punch list. So your customers could get paid sooner. They may even be able to reduce their liability insurance premiums.

Finally, because Preserve contains no harmful chemicals or by-products, it can be disposed of with the rest of normal construction site debris.

So Preserve your windows. It protects the glass, reduces cleanup times, keeps your customers happier. And helps deliver a beautiful home, with glistening new windows. Clean windows.
