MicroLouvre® metal fabrics and frames are 100% recyclable and are proven to last over 60 years.

68% HVAC savings

Air conditioning usage can be reduced by more than 68% and equipment halved - When used as Solar Shading.

90% recycled

The metal fabrics are made from over 90% recycled scrap copper.

Wildfire Threat

Wildfires can occur in multiple locations across the United States, with western states and Texas particularly prone to them. In recent years, we’ve seen the devastating impact of wildfires in the likes of the California, destroying homes and wildlife for weeks at a time.

Residents are often warned against the risk of ash and burning debris which can cause additional risk in areas such as Siskiyou, El Dorado and Trinity counties which are experiencing the impact of global warming and droughts more than ever.

Why use MicroLouvre® Wildfire Screens?

Made from 90% recycled materials, MicroLouvre® screens are completely recyclable and is proven to last for over 60 years. In addition to being an ember resistant mesh it is highly effective as a solar shading system and has been tested to reduce the HVAC load by at least 68% while also delivering additional safety and enhance environmental practices. In areas of the U.S. where wildfires are particularly common, such as California, fire attenuation screens can help to mitigate radiation and provide protection during periods where the risk of wildfires are particularly high as well as prevent embers attacking the property.

MicroLouvre® screens serve as multi-functional window coverings that adhere to the latest fire safety regulations, protecting against ember attacks and burning windborne debris during active wildfires in various states across America, as well as decreasing heat and direct exposure to flames.

Ember Attack and Heat Attenuation

During active wildfires, our screens protect human and wildlife, as well as properties from flying embers and exposure to the fires, but they also reduce and diminish heat radiation. The screens work by dissipating heat through angled bronzed louvres, which results in an industry-leading 49.4% attenuation rate. Smartlouvre MicroLouvre® Screens deliver impressive protection against flying ember attacks and intense heat radiation, without compromising on the open area vision through the window itself.

What makes Smartlouvre fire screens NFDRS compliant?

The National Fire Danger Rating System (NFDRS) utilizes a color system to indicate fire danger risk.

• Green (Low) – Indicates a low risk of fire danger in the area. Any fires that do start should be low intensity and easy to control.
• Blue (Moderate) – Indicates that there’s a potential for fires to start and that the flame length and rate of spread is moderate. These fires are typically not difficult to control.
• Yellow (High) – Indicates that there’s a high potential for danger and that fires may start easily from grass and debris. Fires in grasslands are difficult to control, especially in windy conditions.  
• Orange (Very High) – Indicates a very high risk of fire and that fires in the area can start easily, often spreading faster than suppression can be delivered. Flame lengths are usually long and high in intensity and controlling these types of fires is incredibly difficult.
• Red (Extreme) – Indicates that fires can start easily, burn intensely and spread quickly. These fires are very difficult to control and can last for several days, becoming incredibly dangerous.

MicroLouvre® metal fabric is only 1.55mm thick overall (no thicker than a grain of rice) and each louvre measures only 1.25mm x 0.30mm. protect against extreme fires, preventing radiation and protecting against windborne debris and embers that can spread wildfires faster. Our screens minimize the damage caused to buildings and occupants from fire damage in the event of a high or extreme risk of wildfires developing.

Smartlouvre provide high quality, innovative screens to protect American residents and buildings from the high risks of damage and injury caused by wildfires. Get in touch today for further information about our ember resistant mesh products.

A1/A2 fire performance

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


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

Heat block and solar shading

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

Hurricane proof

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


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.

How it works

How does MicroLouvre® Koolshade® work?

MicroLouvre® screens utilize a super fine louvred metal fabric which is only 1.55mm thick overall (no thicker than a grain of rice) and each louvre measures only 1.25mm x 0.30mm. This prevents flame penetration and burning debris attacks from causing damage and injury to residents. The louvres are spaced 1.2mm apart which delivers exceptional protection against wildfires, along with the additional benefit of solar shading and fire protection for an entire window.

Aircraft-grade aluminium frames with reinforced corners secure the frame neatly and enhance durability, while the top and bottom frames are pre-bowed to minimize deflection and screen tension. All fasteners, anchors and hardware are produced from durable, corrosion-resistant materials for longevity. Our frames are designed to receive continuous anti-vibration wedges on either side which helps to maintain the tautness of the screen and the integrity of the panel even when exposed to wind speeds.

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.
