Key Data Points Shaping Automotive and Architectural Demand
by Nick St. Denis
Window film continues to maintain (and gain) traction across both automotive and architectural markets, even as the broader industries it serves move into more mature growth phases. To better understand what’s driving demand and where growth may come from, the research division of Key Media & Research analyzed a range of automotive, building-related and macroeconomic indicators relevant to the window film industry. Here we highlight five key market signals shaping window film demand today through the remainder of the decade.
Mixed Signals For New Vehicle Sales & Current Stock
New light-duty vehicle sales are projected to remain relatively flat through the end of the decade, with modest declines after the current mid-cycle peak. At the same time, total U.S. vehicle stock continues to edge up moderately as vehicles stay on the road longer. Passenger car stock gradually declines, while light trucks and SUVs continue to expand their share of the fleet.
Why It Matters
This reinforces that automotive window film demand will be increasingly driven by the installed base rather than new vehicle volume. A growing and aging vehicle fleet supports ongoing aftermarket installs and upgrades, while a continued shift toward larger vehicles may increase film value per vehicle.
Broader Automotive Market Aftermarket Slowing But Still Growing
After a strong post-pandemic rebound, U.S. automotive aftermarket growth is normalizing to a low-single-digit pace through the latter half of the decade. While growth is slowing, the market remains firmly in expansion rather than entering a downturn.
Why It Matters
The window film market tends to trend in the direction of the automotive aftermarket sector, though typically at a stronger rate. This remains a major positive, and more so when factoring in adjacent products such as paint protection film.
Leading Film Suppliers Are Outgrowing Their End Markets
The combined revenues of Eastman Performance Films and XPEL increased by more than 60% over the past half-decade—well ahead of broader automotive and architectural remodeling market trends over the same period.
Why It Matters
As two leading suppliers in automotive film (primarily window film and paint protection film) and notable players in architectural applications, their performance underscores the underlying strength of the category. While not fully representative of the entire market, this level of outperformance points to rising penetration and product adoption across the film industry.
Architectural Demand Shifting Toward Retrofit
Residential remodeling softened in 2024 and 2025 before returning to modest growth in 2026, while commercial renovation activity is projected to grow at a high-single-digit pace through 2030. Together, the data point to renovation and retrofit as a primary source of architectural activity despite a slowdown in new construction.
Why It Matters
This environment favors window film as a retrofit-friendly solution. Film offers improved energy performance, glare control and occupant comfort, making it a fit for homeowners and commercial building owners focused on upgrading existing assets.
Consumer Sentiment Soft as Film Demand Stays Resilient
Consumer sentiment has remained volatile since 2021 and weakened again entering 2025, reflecting ongoing caution around inflation, interest rates and general household financial conditions.
Why It Matters
Lower confidence can temper discretionary spending, but it also shifts purchasing toward value-oriented upgrades. Window film can serve as a more affordable alternative to higher-cost automotive and building improvements.
The Bottom Line
Despite slowing growth in automotive and construction end markets, window film continues to carve out a favorable position. Stable automotive aftermarket fundamentals and sustained renovation activity support demand, while leading suppliers’ performance points to overall industry health. The window film market appears positioned for mostly steady, sustainable growth rather than drastic cyclical swings.
