Privacy & Security using MicroLouvre® is efficient and effective.

MicroLouvre® provides internal privacy whilst maintaining clear outward vision.

Most buildings need privacy and security, but not at the expense of reducing daylight, or shutting occupants off from the outside world. Apartments, offices, houses, care homes, hospitals - all properties need privacy.

Using MicroLouvre® can enhance privacy and security through either a stand-alone screen or encapsulated within glazed partitioning. Either option blocks vision from the outside whilst allowing perfect vision out, together with completely natural and unfiltered daylighting.

Use of MicroLouvre®, before and after

How does MicroLouvre® Koolshade® work?

MicroLouvre® is an architectural screen with 700 paper-thin bronze louvres woven into every metre of fabric.

These micro louvres, angled at 17°, block any intrusion from above regardless of the day, night or backlighting, whilst maintaining perfect outward vision at eye level and downwards. Even looking straight at the privacy screens from just a small distance, the tiny striations successfully disrupt inward vision.

MicroLouvre® can be fitted to building exteriors or used internally as privacy screens in offices, for cashiers, receptionists and even integrated within the glazing. It is the most comprehensive window protection and privacy system, providing more benefits than any other full passive window covering system.

Heat block and solar shading

MicroLouvre® Koolshade® blocks up to 100% solar heat gain and up to 100% solar glare.

Uninterrupted vision out and balanced daylighting

Our Solar shading screens provide unobstructed views and access to natural light, improving the thermal, visual and environmental comfort of a building's occupants, proven to have real psychological and productivity benefits.

A1/A2 fire performance

MicroLouvre® KoolShade® is also A1/A2 fire rated, which is now a legal requirement for many residential buildings.


MicroLouvre® Koolshade® allows pure, natural daylight in, whilst still allowing you to easily open the windows so that the directional louvres create upward laminar air circulation - proven to combat viruses and stagnant air.

Hurricane proof

MicroLouvre® Koolshade® is tried and tested in withstanding Hurricane Force 12 and Category 2 Hurricane winds.

Easily outperforms solar glass

With ordinary clear double glazing, MicroLouvre® Koolshade® blocks solar heat better than any solar glass in the summer sun, with a 100% heat block (0.0 gtot), perfect daylight quality and clear outward vision for occupants.

Energy saving

MicroLouvre® Koolshade® has been tested and proven to reduce air conditioning by up to 68%, saving energy costs and hugely reducing the need for air conditioning equipment.


60+ years of maintenance free performance is proven by the Indianapolis City County Building, Peckham Police Station and many other installations worldwide.

How it works

How does MicroLouvre® Koolshade® work?

MicroLouvre® Koolshade® invisibly neutralises solar heat gain and glare before they even reach the window. MicroLouvre uniquely works non-stop providing dynamic g-value (heat blocking) performance to continually dissipate the sun’s heat and energy into the atmosphere but not blocking vision out, natural daylight or natural ventilation; solar shading using our products is efficient and effective.

Credentials and certifications

Certified in efficiency and efficacy

When tested at Fraunhofer, results confirmed MicroLouvre® as the most comprehensive solution for Thermal and Visual Comfort in one system.

The Berkeley Lab included MicroLouvre® in a major research project for PG&E. With MicroLouvre®, daily cooling loads were reduced by 68% on sunny days when compared with dual pane, high performance solar control glass with an internal blind.

The IFC Group have confirmed MicroLouvre® to be A1/A2-s1,d0 : BS EN 13501 Fire Rating, making it one of very few passive and dynamic external sun and solar heat gain blocking systems compliant for use on high rise buildings.

Building Research Establishment (BRE) wind tunnel tested MicroLouvre® screens from different angles and proved it to be indestructible at winds exceeding 100mph/160 kph/46 metres per second.

Smartlouvre Technology Limited is an ISO: 9001 2015 Accredited Quality Management company.

MicroLouvre® has been extensively modelled using computational fluid dynamics (CFD) in SimScale.
