Living Room with Harvey Slimline Windows

The sun’s ultraviolet (UV) light output is largely thought of as a problem of the outdoors. Using sunscreen to protect one’s skin from sunburn is commonplace, but we often don’t consider the damage that UV light can do to the inside of our homes. The damage to furnishings and floors is gradual, so it’s much less noticeable. However, it is still happening, and it reduces their attractiveness and integrity.

UV light is part of a process called ‘photodegradation’, by which light degrades organic materials. It’s a part of the normal biodegradation of organic materials, which is an important natural process. Organic materials includes things like leather, wood, and cotton: precisely what your furniture and flooring is made of. Exposing rugs, leather couches and wood floors to UV light degrades their beauty, causing cracking, peeling and fading much faster than it has to.

An integral part of protecting your furniture and flooring from UV exposure is limiting the amount of UV rays that get through your windows. According to, clear, single-pane glass reflects about 25 percent of the sun’s UV radiation while insulating glass reflects up to 40 percent. Using Low-E coated glass provides additional protection, reflecting up to 74 percent. This reduces harmful rays without changing the overall vibrancy of the light coming into your home.

This will not eliminate fading, but it will slow the damage down considerably. You’ll extend the life and beauty of your furniture and floors, thereby getting more value and enjoyment out of them. Don’t let your investments age any more quickly than they have to. Invest in UV-limiting Harvey windows for your home.
