I have just moved an exterior window and replaced a door with a window for a remodel project but, I made the mistake of not getting the siding first. I thought would just have to go down to lowes or menards and special order it but they only seem to have 6" and I need 4" . The small lumber yard are closed today so I have been looking around the Internet and it looks like most of the places require an order that is much larger than I need which is about 200 linear feet.
Is it possible to use the 6" and have it match up with the 4" ? There would be more overlap but would that cause the wood to not match up evenly. If the viewable area needs to be 2.5 inches than as long both boards have the same thickness in that viewable area would there be any issues?
