Embark on a revolutionary cooling journey with our Reflective Membrane! This advanced self-adhesive solution opens up a world of cooling possibilities with its solar reflectivity of 89% and atmospheric window emissivity of 93%.

Key Specifications:

  • Thickness: A robust 0.81mm, ensuring enduring performance across diverse applications.
  • Reflectivity: A stellar 89%, delivering a matte silver finish while maximizing cooling efficiency.
  • Emissivity: With an atmospheric window emissivity of 93%, this membrane excels in releasing heat into space, providing optimal cooling effects.
  • Adhesive Coating: An extra-thick butyl adhesive coating allows for effective application on rough, uneven surfaces, ensuring continuous zero-energy cooling day and night.
  • Cooling Power: Experience an exceptional cooling power of 143 W/m² as the membrane reflects sunshine and actively releases heat into space, contributing to a sustained cooling effect.
  • Application: Versatile in use, this membrane is perfect for materials like concrete, stone, stucco, and adobe. Ideal for scenarios where a bright silver finish is desired on hard materials with rough, skyward-facing clean surfaces.

This peel-and-stick Membrane not only reflects sunshine but releases heat into space, leading to a substantial cooling effect. Real-world pilot projects demonstrate interior temperature reductions of 11°F (~6°C), resulting in remarkable air conditioning energy savings ranging from 20% to 50%. Transform your space into a cooler, more energy-efficient haven – the possibilities are endless with Radi-Cool Reflective Membrane!
