EXTECH is well known for its glazing systems that incorporate PCSS (POLYCARBONATE STRUCTURAL SHEET). It has achieved air and water infiltration test numbers superior to those of almost any other skylight (including glass skylights). A curtainwall system using PCSS was also recently developed. Since our inception in 1975, we have developed more than 20 systems (many patented) for architectural, commercial and industrial markets.We take pride in our ability to assist architects and owners from concept to completion and help you realize your design goals using the highest quality materials. Where PCSS is concerned you will not find another company able to offer such a wide variety of daylighting solutions under one roof. We believe that we can make you (and your buildings) look good.
