Q. What does Energy Star mean?
A. Energy Star is a government backed program to help consumers identify energy efficient products.
Q. What are NFRC ratings?
A. National Fenestration Rating Council is a non-profit organization that administers the only uniform, independent rating and labeling system for the energy performance of windows, doors, skylights, and attachment products. Our goal is to provide fair, accurate, and reliable energy performance ratings so that architects, builders, code officials, contractors, homeowners, and others can compare different products and make informed product choices.
Q. What are U-Value, Solar Heat Gain Coefficient and Visual Transmission?
A. U-Value is the rate of heat flow-value through a building component, from room air to outside air. The lower the U-factor, the better the value of the component.
Solar heat gain coefficient is a rating measuring a window’s ability to transmit solar heat. It measures both the solar radiation which is directly transmitted, as well as the solar radiation absorbed by the glass and subsequently transmitted. The lower a unit’s solar heat gain coefficient, the less solar heat it trans-mits, and the greater is its shading ability.
Visual Transmittance is the rating that expresses the potential amount of visible light transmitted through a window or door.
Q. Does Public Supply Company manufacture Energy Star products?
A. Yes. All vinyl windows and vinyl sliding doors with optional low-E glass and most swing doors meet or exceed Energy Star requirements.
Q. Does Public Supply Company install the products they sell?
A. Yes. We have installers for all your new construction, home improvement and commercial needs.
Q. Does Public Supply Company manufacture custom windows?
A. Yes. We manufacture custom size replacement windows and custom size new construction windows.
Q. Does condensation on the inside or outside of the window indicate the window is defective?
A. No. Condensation is a natural occurring process in relation to the relative humidity and the air temperatures. The only condensation occurring that indicates a defect is if it is occurring between the two panes of sealed glass.
