Everything about Smart Film
Find answers to the most frequently asked questions about smart film, PDLC technology, and privacy glass solutions.
Smart film (also known as PDLC film or privacy film) is a self-adhesive film that is applied to existing glass. Through an electrical signal, the film switches from opaque (milky white) to transparent. When the power is off, the film scatters light and the glass is opaque - perfect for privacy. When switched on, the crystals in the film align and the glass becomes clear again.
PDLC stands for Polymer Dispersed Liquid Crystal. The film contains small liquid crystals that are randomly oriented in their resting state, causing light to scatter and making the film appear opaque. When electrical voltage is applied, the crystals align, allowing light to pass through and making the glass transparent. This process is instant and reversible, with no moving parts.
The price of smart film depends on several factors: the surface area (m²), the chosen control options (switch, remote control, app control, home automation integration), and whether you choose to install yourself or have professional installation. At PriveGlas, ready-to-install systems start from €179/m² including transformer and controls. Request a quote for an exact price calculation for your situation.
Yes, smart film is very suitable for bathrooms and other humid spaces. The film itself is moisture-resistant when correctly installed. It is important that the electrical connections and busbar are properly sealed with neutral silicone. Smart film offers the perfect solution for bathroom windows or glass partitions where you want privacy on demand.
Smart glass is glass where the PDLC layer is laminated between two glass panes during production - this is a completely new glass product. Smart film, on the other hand, is a self-adhesive film that is applied to existing glass. The big advantage of smart film is that you don't have to replace your current glass, which is significantly cheaper. Both technologies offer the same switchable privacy functionality.
Smart film is adhered to the clean glass surface, similar to applying window film. The glass must first be thoroughly cleaned and degreased. The film is applied wet with a special fluid, after which air bubbles are removed with a squeegee. After drying, the film is connected to the transformer and controls. At PriveGlas, you receive a fully prepared system with clear instruction video.
Yes, smart film can be fully integrated into your home automation system. The film works with common systems such as Google Home, Amazon Alexa, and professional home automation solutions. Via our app control, you can set schedules, group multiple windows, and control the film remotely. Connection with motion sensors or light sensors is also possible.
Smart film is very energy efficient. Consumption is approximately 5 Watts per square meter in the transparent (switched on) state. In opaque state (switched off), there is no power consumption. For an average window of 2m², this amounts to only 10 Watts when transparent - comparable to an LED bulb. Annual electricity costs are therefore negligible.
High-quality smart film has a lifespan of at least 10-15 years with normal use. PDLC technology is proven and reliable, with no moving parts that can wear out. PriveGlas offers 5+ years warranty on product and function. With correct maintenance (regular cleaning with a soft cloth and mild cleaner), the film will continue to function optimally for years.
Yes, this is precisely the great advantage of smart film! The film can be applied to virtually any flat glass surface: single glazing, double glazing, laminated glass, and even tempered glass. You don't need to replace your existing windows. This makes smart film a cost-effective solution for both renovation and new construction. The film is applied on the inside of the glass for optimal protection.
