Introduction to Solar-Control Glazing

Modern glass façades require glazing technologies that balance energy efficiency with visual quality. Solar-control glazing reduces summer overheating and winter heat loss, addressing energy cost concerns and environmental sustainability.

Product Range: ipasol Solar-Control Glazing

The ipasol range consists of multi-layer coated float glass with high selectivity, reflecting long-wave solar radiation while maximizing daylight transmission. This enables bright interiors with reduced heating and cooling energy demands.

Key Performance Parameters

Total Solar Energy Transmittance (g value): Indicates the proportion of solar heat passing through the glass.
Light Transmittance (tL value): Measures visible light transmission for natural illumination.
Thermal Transmittance (Ug value): Reflects insulation efficiency to minimize heat loss.
Colour Neutrality and Reflection: Balances aesthetic appeal with functional performance.

Technical Innovations

Highly Selective Coatings

Up to 10-layer coatings optimize solar control by reflecting heat while allowing daylight, approaching physical performance limits.

Insulating Glazing Unit Design

ipasol units incorporate inert gas fills, spacer bars, and multi-seal systems to enhance thermal insulation and durability.

Warm Edge Technology (its System)

Stainless steel spacer bars reduce thermal bridging at glass edges by approximately 25%, improving edge temperatures and overall insulation.

Gas-Impermeable Silicone Edge Sealant

Allows structural glazing with exposed edges, providing UV resistance and high gas tightness for argon or krypton fills, enhancing longevity and performance.

Complementary Products: ipacolor Spandrel Panels

Designed to match ipasol glazing, ipacolor panels offer weather-resistant, durable, and mechanically stable solutions for fully glazed façades, ensuring a homogeneous appearance and functionality.

Performance Data Summary

Technical tables specify parameters for ipasol products in double and triple glazing configurations, including:

Glass thickness and configuration
Thermal transmittance (Ug values from 0.7 to 1.1 W/m²K)
Total solar energy transmittance (g values approx. 13% to 46%)
Light transmittance (tL values approx. 20% to 73%)
Light reflectance and absorption for outer and inner panes
Shading coefficients and selectivity ratios
Mass per square meter

These data enable architects and engineers to select glazing tailored to specific energy efficiency and aesthetic needs.

Recommendations and Limitations

For outer pane energy absorptance exceeding 50-55%, thermally treated safety glass (ipasafe) is recommended to ensure safety.
Glass thickness must comply with applicable technical regulations; responsibility lies with the customer.
Performance values are based on standard vertical installation; non-vertical mounting may alter results.
ipasol can be combined with sound-insulating, safety, and laminated glass products; however, cast or wired glass cannot be coated.

Benefits and Applications

ipasol glazing reduces heating and air-conditioning costs, enhances occupant comfort through natural lighting, and supports sustainable building design. The product range is proven in prestigious global projects, offering architects design freedom without compromising energy efficiency.

Application Scope and Mounting Conditions

Performance data and testing conditions depend on mounting orientation; non-vertical installations may yield different results compared to vertical façades.

Tolerances and Technical Data

All technical data adhere to tolerances defined by the INTERPANE tolerance handbook, ensuring specification reliability.

Safety Recommendations

For outer panes with energy absorptance above 55% (vertical) or 50% (inclined), thermally treated ipasafe safety glass is advised to enhance safety and performance.

Document Status

Information reflects the status as of January 2012; specifications and recommendations may be updated subsequently.

The Age of Glass Glass architecture is the architecture of the 21st century. Glass façades dominate the cities of the world. Glass fires the imagination of designers. Glass has taken centre stage. But visionary architecture needs high-tech glass. The visual and energy-relevant demands on building envelopes are constantly being raised. This applies particularly for transparent solar control: astronomical costs for air-conditioning loom in summer and for heating in winter. Innovative approaches to control the indoor climate have become imperative! The general trend is toward colour-neutral glazing...

The products in the ipasol range represent top-class solar-control glazing. The newest ipasol generation impressively demonstrates the advantages of these products. Whether total solar energy transmittance (g value), light transmittance ( L value) or thermal transmittance (Ug value), ipasol offers performance that inspires. At long last, buildings can be optimised to save energy yet still have a glazed exterior and bright interior spaces! The ipasol product range has already proven its structural and optical merits in prestigious major projects around the world. ipasol lowers air-conditioning...

Harnessing the Sun The right combination of values The performance of solar-control glazing depends on various parameters such as total solar energy transmittance, light transmittance, thermal insulation, transparency and colour neutrality. Now that innovative coating processes have established themselves as the state of the art, it is important to find the right combination of technical specifications. What is the point of having the most effective solar control, if expensive or unpleasant artificial lighting must be used inside the building, or the view to the outside is hindered? A further...

Firstly, it delays and reduces the heating up of rooms in summer, thus considerably lowering airconditioning costs, which are often much higher than winter heating costs. Secondly, ipasol also improves the ”psychological environment“,...

Also with optimised edge seals its: Warm to the edge As multi-purpose, high-performance glazing, ipasol not only offers excellent solar control but also excellent thermal insulation. However, for future-orientated energysaving strategies, all of the individual components of the solar-control insulating glazing must be examined, e.g. to prevent heat bridges from forming around the edges between the glass and the spacer bar. Consequently, Interpane developed the ”its“ thermal spacer system with a special stainless steel profile. Stainless steel has a much lower thermal conductivity than aluminium....
