What the unsuspecting homeowner does not realize is how harmful these rays are. First, UV causes the decay cycle of plastic to increase. The result is the expected life and usefulness of plastic decreases when exposed to the rays of the sun. Landi s research shows decay of plastic products in your home can occur in as little as 5 years after construction. Areas where plastic moldings exposed to high levels of sun shine show greater decay.
Many people enjoy living in a home that offers excellent natural lighting.
Yet we must remember with light comes UV rays pouring through your windows causing items made of plastic to decay at a more rapid rate than you would expect. The second problem with UV rays is its effect on the color of plastic. Many moldings, cornices, or baseboards will fade in color much sooner than you think. Landi s research indicates in as little time as one year, colors of plastic items may fade. Plastics containing carbon black show greater resistance to color fade and may last 5 times longer than untreated plastic.
