burned appearance on flooring

[Bryce W. Jeffrey]

Aluminum sliding glass doors will freeze and have a build up of ice on the interior. I know because I had this problem once. Especially true in homes with high humidity. Possible someone applied heat to melt the ice scorching the vinyl. Happened in my first home.

Don't think so in this case, Bryce

Sun spot yellow (heat degradation)

• Looks like big freckles in a solid brown or purple.
• Found near heat registers and sliding glass doors.

Stains and Discoloration
<LI id=jsArticleStep1 itxtvisited="1">A variety of reasons cause a vinyl floor to stain or discolor; spills are one of the most common causes. To avoid a spill that stains the floor, wipe up all spills immediately. The sun and heating vents may discolor a vinyl floor as well. Keeping the room shaded during times of the day when the sun is the strongest can avoid discoloration from the sun. Keep heating vents away from vinyl flooring material to avoid discolorations around the vent. Rubber soled shoes and nylon socks or stockings can cause the floor to discolor as well. Remove shoes before walking on the floor.

Heat and direct sunlight can also cause discoloration. Areas near heating vents, radiator legs or supply pipes, as well as spots near windows and glass doors, may be at risk. It is best to avoid installing sheet vinyl flooring in spots that will be subject to high levels of heat, and to use curtains or shades on windows that would allow vinyl to be bathed in direct sunlight for extended times during the day.

I agree with Brian it's heat degradation. I've seen the almost exact same thing as that picture many time before. Newer vinyl doesn't seem to do this and with more houses using low-e glass you don't see this much anymore.

Is the floor covering linoleum?, if so, I agree with Christopher Currins. When I was a child I used to make small fires with the reflecting rays of the sun through a glass. From the picture, it certainly has the looks of a heated area. If the sliding door faces south, you bet the problem is due to the sun heating effects due to its angle and the short distance to the floor when the sun is at its peak.

Personally I've never seen anything even remotely related here in Death Valley though--

Definitely odd, the home owner (my client) had no idea either. The flooring looked perfectly fine from the basement.

Thank you

I believe it is caused by the sun/heat. First time I have ever seen it. Thanks everyone for the thoughts and information.
