Common questions
What is the process for installing window film?
We begin by cleaning your existing window glass thoroughly. Next, we measure and precisely cut the film to fit each window. A specialized application solution is used to adhere the film smoothly, ensuring no air bubbles remain. Finally, we trim any excess film for a clean edge.
How does window film help with energy costs in Washington D.C.?
In Washington D.C.'s warm summers, window film can reject a significant amount of solar heat. This reduces the workload on your air conditioning system, leading to lower energy consumption. It also helps mitigate heat gain during colder months.
Are there specific times that are better for window film installation?
While window film can be installed year-round, moderate temperatures are ideal. Extremely cold weather can affect the adhesive's performance. We can assess your specific situation in D.C. to determine the best time for your installation.
What factors influence the cost of window film installation?
The cost is influenced by the type of film selected, such as solar control or decorative options, and the total square footage of glass being covered. The complexity of the window shapes and accessibility also play a role. We provide a free phone quote.
Is window film a good investment for older homes in the District?
Yes, window film can be a cost-effective upgrade for older homes in D.C. It enhances energy efficiency by reducing heat transfer, improving comfort without requiring a full window replacement. This is especially beneficial for historic properties where window replacement is not feasible.
What is the difference between window film and new windows?
Window film is applied directly to existing glass, offering an affordable way to improve performance. New windows involve replacing the entire unit. Film provides glare reduction, UV blocking, and some energy savings, while new windows offer insulation and structural improvements.
