Glazing with aerogels

Objective

Develop and demonstrate the potential of aerogels for use in diffusing windows, skylights, roofs and Trombe walls. Methods will be developed to fill granular silica aerogel between two sheets of glass.

Aerogel systems containing transparent or translucent gels between two glass panes give a much better heat insulation than existing glass windows. If these systems could be used in windows this could lead to large energy savings. In addition aerogels can reduce the transmission of noise drastically.

Work will be carried out on the following topics:

Evaluation of material and system properties, in particular heat transfer, illumination and acoustic properties and transmission of radiation (ISE, IBP).

Testing of double windows filled with presently available aerogel granules for different window sizes (0,5 x 0,5 m2 and 1,2 x 1,6 m2) and different sealing technologies (Pilkington, Glaverbel, Vegla).

Development of improved aerogel varieties (BASF).

Investigation of window systems consisting of two glass panes filled with aerogel granules : size of the unit, separation between the panes, filling process, evacuation, weathering, long term behaviour, etc. (BASF, Solar and Environmental Technologies, IBP, ISE).

Indoor, outdoor and field testing for different applications (ISE, IBP, Pilkington, Glaverbel, Vegla).
