Customer Reviews
Customer Review: “The BDF NA05 Daytime Privacy and Heat Rejection Window Film does a fantastic job of providing daytime privacy while noticeably reducing heat from the sun on my southern exposure windows. The film is very dark, which works well in blocking out sunlight, and it’s great for keeping my rooms cool without running the AC constantly.”
Customer Review: “There is a warning with this product NOT FOR DUAL PANE WINDOWS. I think most windows in the country are double or triple paned.

They only get direct sun in the morning and so far, so good.”

It works as described.”
Customer Review: “I thought the ‘very dark’ that I purchased would be too dark, and it’s October 20th, and this is a West facing window, so the sun isn’t strong, but it isn’t too dark at all! Plenty of light still comes through. The pictures I took don’t represent what my eye sees, so I won’t post them.”

Customer Review: “This film is fantastic. Western Colorado has been incredibly warm lately, over 100°F, and the indoor temps have been easy to keep. Prior to applying this film the bedrooms could not stay below 80°F in the sweltering months. We use to have to sleep with ice packs in order to cool off. Now, with the film, it’s a noticeable difference.”
Customer Review: “I tried interior window tint before using this product and what a HUGE difference this makes. The room is significantly cooler because the heat stays outside with this exterior window tint. The packaging, instructions, tools included and overall ease of installation make this a 5 star. I’d buy again.”

Customer Review: “I was a bit skeptical about these when I read some of the reviews that said this was hard to apply, but I figured for $10 bucks a pop, I would give it a try. The quality of this vinyl is very good. The vinyl is much thicker than I expected, and the pattern is actually textured onto the vinyl. I have zero complaints.”

I bought it in white and although it’s advertised as privacy film I had my doubts about just how private it was really going to be once I applied it to my windows but I couldn’t be happier.

Complete Buying Guide for Best Window Tint For Double Pane Windows
Essential Factors We Consider
Picking a window tint for double pane windows isn’t the same as tinting a car. The sealed air space is key. First, check the film’s intended use—some warn against dual-pane use due to heat buildup risk. Static cling films are often the safest bet as they don’t use adhesive. Next, define your goal: Is it privacy, heat rejection, UV protection, or blackout darkness? Darker films offer more privacy and heat blocking but darken the room. Reflective films excel at heat rejection. Finally, consider installation: adhesive films are permanent and durable, while static cling is removable and renter-friendly.
Budget Planning
Your budget should reflect your needs. Basic static cling privacy films are very affordable, often under $20 per roll. Mid-range adhesive films with good heat rejection and UV blocking, like our top picks, offer the best value for long-term performance. High-end, professionally installed ceramic or spectrally selective films cost more but offer the best clarity and heat rejection without dark tints. Remember, a good film can pay for itself over time by lowering your air conditioning costs.
Final Thoughts
Always prioritize films that mention compatibility with insulated glass. When in doubt, opt for a non-adhesive, static-cling product to eliminate any risk to the window seal. Start with a small, less-conspicuous window to test the film’s look and performance before committing to your entire house. The right tint will make your home more comfortable, private, and energy-efficient.
Frequently Asked Questions
Q: Can you put window tint on double pane windows?
A: Yes, you can, but you must choose the right product. Standard adhesive tints can potentially cause issues due to heat buildup between the panes. Static cling films that use water adhesion are generally considered a safer, non-permanent option for double pane windows. Always check the manufacturer’s specifications.
Q: What is the best type of window film for heat reduction?
A: For the best heat reduction, look for films with a high heat rejection or Total Solar Energy Rejected (TSER) percentage. Reflective (metalized) and ceramic films are typically the most effective. Films applied to the exterior of the glass, like the BDF EXNA20, can also be extremely effective as they reflect heat before it enters.
Q: Does window film provide privacy at night?
A: Most one-way privacy or reflective films only work during the day when it’s brighter outside than inside. At night, with lights on inside, the effect reverses, and people outside can see in. For 24/7 privacy, you need a dark, non-reflective tint or a blackout film combined with curtains or blinds.
Q: Is window film easy to install yourself?
A> Static cling films are very DIY-friendly. They require only a spray bottle with soapy water, a squeegee, and a utility knife. Adhesive films are more challenging, as they require a perfectly clean surface, a lot of solution to position the film, and patience to smooth out bubbles. Having a helper makes any installation much easier.
Q: Will window film damage my windows when removed?
A> Static cling films are designed to be removed cleanly with no residue. Traditional adhesive films can leave glue behind and may be difficult to remove completely after years of adhesion, potentially requiring solvents and scraping which could scratch the glass.
Finding the best window tint for your double pane windows is all about matching the product to your specific needs.
