i think we have paneling underneith our existing wallpaper
Color is actually a result of how light reflects off surfaces. From a light source, i.e. the sun or a lamp, to the surface its reflecting off of. Black colors are a result of less light being reflected and more light being absorbed by the surface and material while white reflects more light absorbing it less. The color of an insulator makes no difference if it doesn’t receive any light but the color of a surface is a factor in how much thermal energy is absorbed when its exposed to light. For Example black shingles on a roof do warm up considerably during the day because they are in direct sun, this energy is transferred into the frame and insulation of the house to keep it way from the interior. A wall that is painted white with just as much sun exposure as the roof might be warm but its not as hot. There are other factors such as how reflective (shiny) the material is or the density [thick thin] and material of the objects (wood concrete paint metal) that affect how much thermal energy is stored [heat] a good way to test it would be to have two identical blocks of wood with a surface painted black and white sitting in the sun for a few hours and test the surface temperature on the front and then the back. Which ever block of wood is hotter on the back side the more thermal energy transferred to the wood.
Some where there is a image of a helmet and fatal strike percentages. I found it interesting that 50% where below the eyes. What was more interesting was a great difference between fatal strikes from the left as compared to the right side of the helmet! To receive the protection level of a full face helmet you must wear a full face helmet! Do not waste you money on a flip front the fastening retaining mechanism will disappear with something as small as a bird strike and not be around for additional strikes when you need it.
