About the product

Smart film is a new type of electronic light-control product. Electronically controlled smart film is a liquid-crystal/polymer hybrid injected between two transparent conductive film layers.

Polymer Dispersed Liquid Crystal (PDLC) smart film is often described as the curtain of the future, designed for new or renovated spaces for instant upgrades. Its key benefit is instant switching from opaque to transparent, allowing light into the space while reflecting heat (UV and IR).

Technical principles

PDLC film

Without power, electronically controlled smart film is opaque. When voltage is applied, liquid crystal molecules align, switching from opaque (OFF) to transparent (ON).

PNLC film

PNLC film is a more advanced model, while keeping a similar principle. Unlike standard PDLC smart film, the PNLC operating principle is that the film remains opaque without power and becomes hazy when connected to electricity.

Self-adhesive or laminated installation

The first distinction to understand is between self-adhesive PDLC smart film models, used for retrofit installation on existing glass surfaces, and laminated models, which have no adhesive layer and are designed for installation between two layers of glass during fabrication — for example in PVC or aluminium joinery or glass walls.

Models and applications

Lumi Projekt offers several PDLC smart film models with different technical specifications. It is important to note that almost all models are available in self-adhesive or laminated installation.

Basic model

This entry-level model provides all the benefits of smart film — privacy in a second, thermal and sound insulation, UV and IR protection — at the most affordable price. The Basic model offers light transmittance of 84–86% when the film is frosted/off and haze of approximately 4–5% when the film is clear/on.

A great solution for offices and smaller business spaces, medical environments, and anywhere privacy is needed without extra requirements at a lower price point.

Recommended price for this model in self-adhesive installation with full preparation for installation is €99.99 (incl. VAT) per square metre.

Plus model

The most cost-effective and most popular Plus model is a step above the previous model and also provides all the benefits of smart film, but comes with better light transmittance of 88–91% when the film is frosted/off and haze of approximately 3–4% when the film is clear/on.

Ideal for residential installations, conference rooms and business spaces, hotels and apartments, retail and other buildings with more frequent use where better optical quality and durability are required.

Recommended price for this model in self-adhesive installation with full preparation for installation is €129.99 (incl. VAT) per square metre.

Premium model

When only the best will do, the Premium model is the right choice. It offers all the benefits of the previous models but delivers the best performance with light transmittance of 90–92% when the film is frosted/off and haze below 3% when the film is clear/on.

Where there is no compromise: luxury residences, premium hotels and villas, representative business spaces and projects where aesthetics and maximum transparency are a priority.

Recommended price for this model in self-adhesive installation with full preparation for installation is €164.99 (incl. VAT) per square metre.

High-temperature H-T model PDLC smart film

High-temperature model

The H-T or high-temperature model is developed for demanding conditions where glass surfaces are exposed to high temperatures, intense solar radiation and increased UV load for most of the day. It retains all the advantages of smart PDLC film comparable to the Basic model, but is enhanced to withstand temperatures up to 105 ℃.

Ideal for glass facades, shop windows, winter gardens, balconies, pool areas, atriums and other projects exposed to prolonged sun and elevated temperatures, where maximum resistance and reliability are required.

Recommended price for this model in self-adhesive installation with full preparation for installation is €189.99 (incl. VAT) per square metre.

PDLC smart film in colors — red, blue, orange, green, grey and black

Color models – Red / Blue / Orange / Green / Grey / Black

Our color models provide all the advantages of standard PDLC smart film with the added option of choosing a color with an additional filter film layer. They give a space a unique visual identity and decorative character. Along with effective privacy control, they enable attractive glass surfaces that fit into modern architectural and design projects.

Ideal for luxury interiors, hotels, restaurants, wellness centres, showroom spaces, retail and all buildings where privacy, aesthetics and distinctive design are equally important.

Recommended price for this model in self-adhesive installation with full preparation for installation is €109.99 (incl. VAT) per square metre.
