Transparent insulation glazings

Most transparent insulation (TI) products can be described as glazings filled with transparent insulation material. There are some that, in addition, use the potential of low-e coating and noble gas fillings (see Figure 9.4.4); but many only rely on the insulation of air-filled structures. Glazings thicker than

50 mm to 60 mm need a breathing opening and cannot be hermetically sealed. With a step rebate, these products may be integrated like slim glazings in ordinary profiles of transom-mullion construc-

Opaque solar absorber modules

Instead of highly translucent materials, opaque materials such as cardboard structures or mineral wool can be used behind a glass pane to absorb the solar radiation. The Gap solar solarpanel (previously ESA Solarfassade; see Figure 9.4.5) and the Isover Design FP6 (no longer on the market) are such systems that can also be used in front of walls with low storage capacity and density.

Other products and overview

A product different from the type above is TI made from multi-channelled duct plates. The company GlassX AG in Zurich recently developed a complete glass element, including latent heat storage and seasonal shading using prismatic sheets. From some manufacturers, only the transparent insulation

1 The total solar energy is for diffuse radiation - thus, it is much lower than for normal incidence!

2 Many manufacturers have several product variations with differing characteristics.

3 The product characteristics are typical values for these products.

4 The thermal resistance is given for 10°C average temperature; it is not a rated value that includes safety allowance.

material can be obtained. This can be used by architects or craftsmen to develop own solutions - for example, using wooden window technology or filling a timber framing construction. Humidity transport, ventilation and condensation have to be considered in such cases.

Table 9.4.1 gives a short overview of characteristic values for a range of selected products. Most values are measured values; but some are extrapolated from material composition and manufacturers' data. The data can be used for approximated design. When in doubt, manufacturers should be asked for more detailed data.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
