Nanotextured Surface Dramatically Improve Solar Cell Efficiency. The Engineer posted on January 22, 2015 | | 4074 views. Reducing the amount of sunlight that bounces off the surface of solar cells helps maximize the conversion of the sun's rays to electricity, so manufacturers use coatings to cut down on reflections.
The main entry door must conform to IRC specifications. Exterior doors often are the most visible parts of a house and like interior doors, are available in standard sizes. They range in width from 2 feet to more than 3 feet, and in height from 6 feet, 8 inches to more than 8 feet. Standard thickness is 1 3/4 inches.
Standard thicknesses are 40mm (1â in) and 44mm (1 in). Make sure you use the correct thickness to match any existing doorframe to ensure the door is flush with it when closed. Failure to do this will require that the door stop strips of the doorframe are repositioned. Standard heights and widths are; 1981mm (6ft 6in) x 762mm (2ft 6in)
