Bob,
Heartland does use blackout shades in the Landmark product. Your requirements not withstanding, there are differences in what we put into different Heartland brands. This seems to be one of those differences. That said, if your windows happen to be the same size as any of the new Landmark windows, you could "likely" order the shades through Heartland Parts. Another option may be to go through our supplier. I am not certain who that is but a call to the plant could nail that down if you were interested in making a retail purchase.
