Why does solar reduction matter? The urban heat island effect, caused by the over-reliance on heat-absorbing construction materials, means that cities are often 1–3°C (1.8-5.4°F) warmer than their rural surroundings. This puts significant pressure on cooling systems, increasing electricity consumption. The effect is further amplified by the use of fully-glazed facades, where direct sunlight causes overheating. In hot and humid cities, almost half of the electricity used by high-rise office buildings goes towards cooling.

How Kaynemaile-Armour works

The Kaynemaile-Armour mesh facade system provides a cost effective method to significantly improve the thermal environment inside a building, by reducing radiant heat transfer from direct sunlight. Its unique design lets daylight in, but allows you to manage the passive solar gain within the building envelope — all while maintaining visual transparency.

 

There are 3 key factors at play:

Deflecting sunlight: The Kaynemaile-Armour facade system has been shown to deflect up to 70% of visible and infrared light waves, which are linked to overheating. The Kaynemaile-Armour system provides an alternative route to solar gain protection. In many environments, shading systems like Kaynemaile-Armour have been shown to be even more effective at managing interior temperatures than costly, retrofitted glazing.

Insulative properties: Steel mesh products are highly thermally conductive, so under direct sunlight, their temperature rises and they transfer radiant heat into the building. In contrast, Kaynemaile-Armour mesh is made from a high-grade polycarbonate, which is an insulator. Our mesh remains at a near ambient temperature, even at the height of summer, moderating the thermal environment, and reducing its running costs.

Cooling properties: In our three-dimensional mesh structure, a high proportion of the mesh surface area is always in shade, which helps to control temperatures. In addition, as air passes through the cross-sectional open area, it provides a cooling effect. A typical two-dimensional steel mesh or perforated sheet offers much lower visible open area, significantly less airflow, and higher air temperatures, increasing the building’s overall thermal load.

 

With Kaynemaile-Armour you can reduce the total heat gain on the building envelope significantly. By protecting the building from harsh sunlight and not restricting the cooling effects of air movement, building engineers can reduce the air conditioning design and system costs, as well as reducing the total energy consumption costs in hot climates.

 

PROJECT SPOTLIGHT

Ideal solar management applications are buildings that require a low energy design, or those that can’t be cooled by traditional methods, like car parks.

Loma Linda University Carpark Facade Case Study

Kaynemaile-Armour was used on the Loma Linda University carpark facade in San Bernardino, California. The hot, dry climate meant sun protection and airflow were critical requirements for the facade.

With a fast install time and simple fixing details, Kaynemaile-Armour exceeded the project requirements—providing enhanced air flow through beautiful louver-like strips.

The Kaynemaile-Armour facade system significantly reduced the surface temperature, from 40°C (104°F) to 28°C (82°F) in Kaynemaile-Armour protected areas*.


* The specific benefits will vary from geographical location. The numbers included here are based on a combination of scientific tests, field readings, observations and weather conditions.

 

Visual transparency means inside-out visibility

Unlike traditional two-dimensional perforated steel panels and meshes, Kaynemaile-Armour’s three-dimensional nature gives a consistent visual open area, providing great visual transparency and unobstructed views from the inside out. Other flat panel materials have an open aperture only when measured perpendicular to the panel face.
Kaynemaile-Armour gives a massive 140-degree panoramic view.

Kaynemaile Light Transmission Test Results

An independent test was undertaken on Kaynemaile mesh by the Institute of Geological and Nuclear Sciences (GNS), New Zealand. This graph represents the average light transmission through Kaynemaile-Armour in standard exterior colours (Bronze, Steel, Copper, Obsidian Black, Translucent Black, and Silver).

The transmittance of single glazing is close to 100%, and for typical steel mesh, it can be more than 53%—in other words, more than half of the sunlight that hits a steel mesh can enter a building. In contrast, the opaque Kaynemaile mesh shows an average transmittance of 30% for visible light (400nm – 700nm), and just 22% transmittance in the infrared.

Kaynemaile Architectural mesh is a patented, world-leading innovation. We think the benefits of the Kaynemaile product are extraordinary.

Fire Resistant

Kaynemaile mesh achieved a Group 1S in the AS/ISO 9705 room test (equivalent to the NFPA 286 room corner test). With an ASTM D 2843 smoke index of 70.9°, ASTM 635 HB-CCI and NFPA 701-pass. We use FR-V0 material that is rated self-extinguishing. Contact Kaynemaile for more specific information for your location.

Unlimited Screen Size

We are not limited by panel size—we can make our screens to any height or width without joins or distracting gaps. This gives you freedom at the design concept stage that other materials don’t. Making our screens to the size you need them means less structure, less fixings, and less time on site.

Super-Fast Installation

Kaynemaile-Armour is lightweight (3kg per square metre) and goes up fast, cutting down the install time dramatically and saving costs. Our fixing systems are simple and we don’t need the same level of sub-frame as metal products. This means our installed rate is more cost effective than metal or glass panel products.
