VK REVERSE
Smart glass for privacy
For applications requiring reverse visibility control, we present VK Reverse. This PNLC (Polymer Network Liquid Crystal) technology is designed to operate with inverted control logic. In its default state (unpowered), the glass is in OFF mode (transparent), revealing the external or internal environment. When activated (ON), the glass rapidly transitions to opaque mode, ensuring privacy. With VK Reverse, every environment adapts to your needs in real time, enhancing wellbeing, energy efficiency and safety, while offering a modern, versatile glazing solution for architecture and interior design.

BENEFITS
Safety
Mechanical resistance
VK Reverse is rendered even more resistant to mechanical stress thanks to PDLC technology, and the plastic materials laminated within the glass: it has achieved class 1(B)1 certification, the highest in the laminated safety glass category, meaning it does not break into separate pieces when smashed, as well as passing the test for resistance to heat and humidity.
Water resistance
VK Reverse is safe in humid and wet environments. IPX7 tested, it can be installed in bathrooms and shower enclosures.
Hygiene and cleanliness
Privacy without curtains
Glass is a sterile material, and is easy to clean and sanitise. With VK Reverse you can eliminate fabric curtains, which collect dirt and germs, and are difficult to wash.
Customisation and quality
Artisanal quality and care
VK Reverse glass is hand-made following a rigorous in-house protocol that keeps track of each piece throughout the entire production process. Artisan processing makes it possible to ensure accurate quality control on every single piece of glass produced, as well as precise and scrupulous post-sales service.
Customisation to the millimetre
VK Reverse glass can be customised to the millimetre in size, and is available in all thicknesses present on the market, as well as in a range of colours and types, such as extra clear, bronze and grey. Its variety and flexibility mean it can be used in a vast range of different contexts.
Ease of use
Simple and intuitive
From opaque to transparent at the touch of a button: with control devices that switch from OFF to ON in less than 0.1 seconds.
Long-lasting and easy maintenance
VK Reverse is a durable product, tested for over 100,000 hours in operation, and with electrical components that are easy to maintain without impairing the glass.
Sound insulation
Sound insulation and privacy
VK Reverse offers particularly strong performance in terms of sound insulation, tested in independent laboratories with a result of Rw 38 dB for glass measuring 55.4 mm in thickness.
This is an important quality in working environments and healthcare facilities, where obscuring the view of certain spaces is not sufficient, and confidentiality, concentration and rest are also fundamental.
Energy saving
Low energy consumption
When switched on, the energy consumption of VK Reverse is extremely low: 1.2 W per square metre, less than an LED lamp. It can also be switched on and off using a programmable timer.
Solar screening
In opaque mode, VK Reverse blocks out UV rays and ensures greater solar screening than traditional double glazing, keeping room temperatures lower and more comfortable, and reducing energy consumption from air conditioning systems.
KEY FEATURES
Advanced energy efficiency
Opaque mode is maintained without the need for continuous power supply, significantly reducing energy consumption.
Response speed
Instant switching between transparent and opaque, to quickly adapt to privacy needs or natural light exposure.
Heat and brightness reduction
Thanks to crystal dispersion in the opaque state, the glass also acts as a filter for heat and UV rays.
Long-lasting
The reverse configuration reduces electrical stress on the materials, ensuring a longer lifecycle compared to other technologies.
