What does D4 profile mean? D4 means “Double”. In the simplest terms, it means that a vinyl siding panel has two rows of siding and each row is four inches tall. The four-inch vinyl siding or D4 is 8 inches or 20 centimeters wide, while a 5-inch double or D5 is 10 inches or 26 centimeters wide. In terms of comparison with size, there is no relevant difference between the two, other than an inch in size between the width of the vinyl siding.
Insulating vinyl siding is a great way to improve the appearance of your home with a new coating while also adding insulation that will help lower your utility bills, all in one step. Installing vinyl siding on your own will be reasonably easy if you have different power tools, but if it isn't, it's best to leave the work to professionals. Like any other type of siding used in homes, vinyl siding is measured by its length and width. Vinyl siding can be installed over common wood siding, such as plywood, oriented strand boards (OSB), or other materials (for example, there is a wide variety of lengths and widths for vinyl siding) on the market, and the same design for vinyl siding may differ in size from one producer to another).
When properly sized for both the vinyl siding and the J-channel, your home's exterior cladding will look perfect and will be installed by a professional.
