Overview
Pilkington Optiwhite™ is an extra-clear, low-iron float glass range designed for high solar transmittance. It delivers improved solar energy conversion and stable optical performance over long-term exposure, making it suitable for multiple solar technologies.

Product Range
The range includes Pilkington Optiwhite™, Pilkington Optiwhite™ S (optimized for the solar industry with enhanced solar transmittance) and Pilkington Microwhite™ (ultra-thin versions with thicknesses down to 1.0 mm). Detailed performance tables summarise optical and physical properties by product variant.

Features & Benefits

• Very high visible light and solar heat transmittance for improved energy yield.
• Stable long-term optical performance with no solarisation after prolonged sun exposure.
• Available in annealed or tempered/toughened forms for Optiwhite™ and Optiwhite™ S; Microwhite™ offered in annealed form only.

Typical Applications
Recommended as cover glass for Thin Film photovoltaics, Crystalline Silicon PV, Concentrated Solar Power (CSP) systems, solar thermal collectors and solar mirrors.
