Welcome to FAQ Friday – a new feature on the JELD-WEN blog. Each week we will answer a Frequently Asked Question about our products, service or industry. We hope you find these answers helpful! Let’s look at this week’s question:
What is “Low-E” glass?
Low-emissivity (or Low-E) glass is window glass that has been coated with a low-emittance material designed to reduce the ultraviolet factor (u-factor) through absorption or reflection of solar radiation. Low-E glass repels ultraviolet rays that cause heat during summer months and absorbs rays to let in heat during winter. This can help lower energy bills significantly, year round.
