Our Products

We provide both Monolithic Parabolic Mirrors and Laminated Parabolic Mirrors for CSP application.  We use the highest performing solar float glass to create monolithic and laminated parabolic mirrors with high, trend setting reflectivity. Thermosol’s precise manufacturing process yields a smooth and accurate mirror.

Monolithic Parabolic Mirror

In this design, the Mirror is heat bent before silvering and the backing paint is the protective layer for silver and/or copper metals against the environment.

Laminated Parabolic Mirror

In this design, the mirror is made with a thin front glass and a thicker backing glass laminated with polyvinyl butyral (PVB) film in between. The front glass is heat bent. The backing plate is then laminated to the slivered front plate as the protective layer against the environment. The laminated designs are aimed at better reflectivity and better durability.

Product Specification

Designed specifically for CSP Parabolic Trough systems, Mirrors would be available in standard RP2, 3 and 4 design configurations. Also, as per the requirement of the customers, our manufacturing plant produces both the Monolithic Mirrors and Laminated Mirrors.
