Our Climate Controlled Glass windows allow a good amount of light to enter your room while controlling the natural heat from the sun, which prevents overheating in the summer and reduces heat loss during colder periods. When used in combination with high-performing roof glass, Climate Controlled Glass can help maintain a constant temperature inside your home, providing year-round comfort. Additionally, the high light transmittance of the glass means that you’ll require less interior lighting during daylight hours, which can help you reduce your energy costs and carbon footprint.
