Sustainable Construction

Prelco offers a wide range of high performance, energy efficient glass products that have a significant impact on the performance of a building.  In addition to contributing to the reduction in energy costs, our glazing helps maintain a level of occupant comfort while providing natural light inside buildings.

Prelco's Thermalite™ Energy-Efficient Glazing is an ideal product for a sustainable construction project. Indeed, low-e glasses, tinted or reflective can reduce the gain or loss of heat through the windows, control glare caused by the sun's rays, increase the resistance to condensation and more.


Like Thermalite ™, Prel-Shade glass (thermochromic glass) limits the heat gain in a building while facilitating the provision of natural light. Changing color depending on its level of exposure to sunlight, Prel-Shade glazing is a major asset in a construction project where we seek to reduce energy consumption.
