Dear Sirs,

We would like to thank you for your interest in Cabot Corporation’s translucent Nanogel
aerogel, a novel solution for outstanding natural light diffusion, thermal insulation and
acoustic properties.

Nanogel is Cabot's trade name for its family of silica aerogels. Cabot is the only company to
develop a commercialized process that allows production of aerogel material under ambient
conditions. This process allows Cabot to control the material’s porosity, pore size and
distribution, and bypasses the high-cost traditional method of super-critical drying, so that
Nanogel aerogel can be manufactured in a safe and continuous manner.

Aerogel used in fenestration products is an amorphous form of synthetic silica structured by
nano – sized pores. About 95 percent of its volume is occupied by air, making aerogel the
world’s lightest solid material. The low solids content and extremely small pore size make it
very effective against conduction and convection of heat. The amorphous silica particles are
inherently safe under most construction materials measurements. Additionally, aerogel is
chemically and ultraviolet (UV)-stable, nontoxic, noncombustible, and generate no smoke. It
is also permanently hydrophobic so it repels water, resists vapor migration, and does not
support growth of mold or mildew spores. Aerogel is also permanently non-yellowing, with a
luminous white appearance. Since silica is inert, aerogel can last the life of a structure and
be recycled when the building is decommissioned.

Some products may perform similarly in one area, but Nanogel excels in all of the following:
• Unsurpassed thermal insulation: 0.018 W/m.K @ 25°C. This allows more natural
  daylight through a roof and/or a façade while minimizing heat loss.
• Good light transmission: up to 80% per cm. Natural daylight creates a more efficient
  and beneficial interior environment, with positive psychological and physiological effects.
• Excellent light diffusion: translucency and even distribution of light inside the building.
  This allows a reduction or elimination of glare and improved comfort. Solar blind systems
  may not be necessary, meaning a reduced initial investment, no need for maintenance,
  and no modification of architectural design.
• Reduction of solar transmission.
• Improved acoustic insulation: 100 m/sec vs 340 m/sec in air. 50% reduction at
  100Hz.
• UV resistance and hydrophobicity: no growth of fungus nor mildew, performance will
  not deteriorate over time.

•   Considered as a non-combustible (ASTM D1929) and non-smoking material (ASTM
    E662).
•   Low weight: 70-100 kg/m3.
•   Architectural freedom: translucent glazing with Nanogel aerogel balances daylighting
    with thermal performance. Architects can now meet or exceed the most stringent building
    codes (UK: Part L; France: RT2005; Spain: CTE etc.).
•   Environmentally friendly: financial and energy savings less heating and/or air-
    conditioning, reduced artificial lighting reduction of CO2 emission and energy bills.

Glazing systems incorporating Nanogel aerogel insulation can offer architects and building
owners affordable and practical options in a variety of fenestration systems, satisfying both
the relevant building codes and bringing diffuse light indoors.




•   Multiwall polycarbonate sheets (10, 16, 25, 32, 40, 55mm)
•   U-channel glass (i.e. Profilit™ / Reglit™ or Linit™)
•   Glass Fiber Reinforced Polyester (FRP) panels (50 and 70mm) from Scobalit or Kalwall
•   Double pane glass (limited sizes available – request sizing info)

For example:
• U-channel glass system + a clipped polycarbonate sheet + Nanogel :1.1 W/m²K
• 25mm thick polycarbonate sheet + Nanogel has a U-value of 0.89 W/m²K
• 55mm thick polycarbonate sheet + Nanogel has a U-value of 0.50 W/m²K
• 50mm thick Scobatherm panel (Scobalit+Nanogel) has a U-value of 0.48 W/m²K

                                                 -2-
• Double pane glass could potentially go as low as 0.30 W/m²K
• 70mm thick Kalwall+Nanogel panel has a U-value of 0.26 W/m²K
Profilit™ and Reglit™ are registered trademarks of Pilkington Group Limited / NSG.
Linit™ is a registered trademark of Lamberts.
The U-value of Nanogel-insulated systems is not affected by the angle of installation. Glazing
materials remain effective against convection even in sloped and horizontal applications
where their traditional counterparts lose much of their performance.

Cabot manufactures Nanogel® aerogel in commercial quantities at a plant at Frankfurt,
Germany. This facility processes filled polycarbonate panels and provides clips for attaching
polycarbonate panels in U-channel glass systems. Cabot can fill can go up to 6m long and
2.1m wide.

ThermalWrap™ is a combination of fibers and Nanogel particles available in thicknesses of 4,
6 and 8mm. ThermalWrap can be used as an extra layer inside ETFE and PTFE membranes in
order to improve thermal and acoustic insulation as well as light diffusion in textile
architectural systems.




Thermal insulation and energy savings
With Nanogel translucent aerogel, now architects and building owners can meet stringent
energy codes (such as Part L in the UK, RT2005 in France, CTE in Spain, etc…) and
dramatically improve the thermal insulation of the glazing area. The reduced U-value means
improvement in the building envelope’s thermal performance as well as larger translucent
surfaces than standard skylights, vaults or facades. The incorporation of Nanogel eliminates
glare issues and allows a reduction in lighting costs. These factors combined with substantial
savings from decreased heating and air-conditioning potentially result in high energy and
cost savings.

 Energy loss calculation
 When calculating according to the guidelines given by the DIN 4701 standard, an average
 annual saving of between 0.9-1.3 liters of oil or 1.0-1.5 m³ of gas per m² of glazing area will
 be obtained by decreasing the U-value by 0.1W/m² K. The table below shows the minimum
 and maximum amount of savings of fuel or gas consumption per m² glazing area when the
 U-value is decreased by varying amounts.

 Calculation examples of annual energy savings when standard glazing is replaced by a
 Nanogel aerogel-filled panel.

         Option 1: 4 mm thick mono-layer glass: U-value 5.8 W/m² K
         Option 2: Nanogel filled polycarbonate 16 mm : U-value 1.3 W/ m² K
           U-value difference: 4.5 W/m² K
                  Annual energy savings per m²: 50,000 liters of oil or 55 m³ of gas
                  Annual savings: Oil: 34,600 €; Gas: 30,800 €

                   Hypothesis : Cost of gas: €0.55/m³, Cost of oil: €0.70/liter

Nanogel in action
These images demonstrate the dramatic thermal performance difference between the bent
multiwall polycarbonate panels of the vault which are filled with Nanogel aerogel, and the
vertical side panel that is not insulated. The pictures show that the surface temperature of
the unfilled panels is much higher than those filled with Nanogel. This indicates that the heat
loss through the unfilled panel is much greater.




                         Pictures taken at the EDIS center, Fleury Merogis (Paris area), France.

This example demonstrates the major difference between Nanogel filled polycarbonate
panels and the three doors based on a standard glass pane.

Even in non-daylighting applications, such as the core insulation of a wall cavity, the strong
benefits of aerogel insulation are clearly demonstrated:

Reuse
Since Nanogel® is a very stable material (UV resistant, limited yellowing, etc.), the particles
can be removed from the panels and reused several times at the end of the lifetime of a
building, making it an environmentally-friendly solution.

•   Nanogel aerogel can help builders to qualify for the LEED certification (Leadership in
    Energy and Environmental Design)




Other benefits

•   Research has shown that full-spectrum natural daylight generally provides the most
    satisfying conditions for building occupants.

•   Many standard daylighting products have been adapted for use with Nanogel, creating a
    variety of choices for both vertical and overhead glazing applications. Nanogel-filled
    panels may be used in roofs (rooflights/skylights, smoke vents, vaults, ventilation
    systems, conservatories, etc.) but also in facades, curtain walls and separation walls.

•   Nanogel aerogel’s high porosity and fine structure ensure improved acoustic
    performance. Due to the tenuous solid structure of aerogel there is little solid-phase
    vibration. Sound waves transmit through the material at a much reduced speed (100
    meter/second compared to 340 meter/second through air). Sound insulating properties
    are particularly noticeable at lower frequencies (40-500Hz), reducing nuisance noise like
    airplane and truck sounds. The human ear can differentiate a drop of 3 dB, so a reduction
    of 5 dB is impressive, a 25mm aerogel-filled polycarbonate panel reduces the value from
    18 to 23 dB.
