Abstract

Transparent insulating materials: experimental data and buildings energy saving evaluation C. Buratti Department of Industrial Engineering, Perugia University, Italy Abstract The aim of the present paper is the study of the thermal and optical properties of innovative transparent materials for glazing systems. Thus, some innovative transparent solutions concerning Transparent Insulating Materials (TIM) were considered: monolithic silica aerogel and capillary geometric media. Initially, the optical properties of the single pane of aerogel were measured with a spectrophotometer, evaluating spectral transmittance vs. wavelength. Then, eleven different samples were realized, by assembling several types of glass (simple, float glass with various thickness, reflecting glass, low-e coated glass), in various combinations, with a pane of aerogel. Each sample could be considered as a double glass with aerogel in the interspace. In the same way, the capillary layers of TIM were inserted between two glass
