What is Solar Shading?

Solar shading is a method by which solar radiation in the form of heat and light can be mitigated in a building. While natural heat and light are essential in most buildings and modern architecture uses it more and more there are occasions when the levels are too high. This leads to high temperatures and too much light.

Solar shading is a general term for a range of methods used to reduce the amount of solar gain. Our MicroLouvre Koolshade® mesh fits easily on the outside of windows thus reducing the amount of heat gain and direct sunlight whilst still allowing a clear view through the window.

As a solar shading solution it offers many benefits and doesn't suffer from mechanical problems or user error because of its passive nature.

The Multiple Combined Benefits of MicroLouvre Koolshade® for Solar Shading.

Solar shading using our MicroLouvre Koolshade® is unbeatable, efficient and effective.

All glazing needs solar protection. Working differently from traditional external, internal blinds and other solar shading devices, which reflect, distort, and restrict vision and light, MicroLouvre Koolshade® invisibly neutralises solar heat gain and glare before they even reach the window. MicroLouvre Koolshade™ works non-stop to give you solar control , dissipating the sun’s heat and energy into the atmosphere whilst allowing full vision out, and daylight and natural ventilation in. MicroLouvre Koolshade® solar shading systems are efficient, effective, and maintenance free with a zero-total cost of ownership.

We are a UK company providing high-quality solar shading systems for all commercial and residential buildings. Our unique material is a highly efficient and effective part of solar shading architecture. We make a totally unique and unbeatable mesh that offers efficient solar protection by keeping the insides of office buildings and public spaces significantly cooler and reducing the need for excessive air conditioning.

Heat block and solar shading

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

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.


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.

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.

A1/A2 fire performance

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

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.


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 Koolshade® 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. Our unique material is the perfect solar shading device, it can be installed easily, has excellent environmental credientials and offers a cost effective solution to solar gain.

Alternative To Solar Shading Blinds, Sun Shades and Films

Windows exposed to the sun allow short wave radiation to flow through where it converts to long wave radiation which is then trapped inside allowing temperatures to exceed 38°C. MicroLouvre Koolshade® solar shading lourve works totally differently from traditional external and internal solar shading blinds by simply and invisibly neutralising solar heat gain and glare before they even reach the window, like a heat sponge soaking up the heat and energy and discharging it into the atmosphere like a chimney. The standard alternatives like sunshades for buildings, mechanical solar shading louvres and solar shading blinds all have major flaws be it from potential user error, cost or efficacy; MicroLouvre™ does not.

Certified in efficiency and efficacy

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

The Berkeley Lab included MicroLouvre Koolshade® in a major research project for PG&E. With MicroLouvre Koolshade®, 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 Koolshade® 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.

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