Swan puts a disclaimer in their catalogue about their pics sometimes not matching due to pre-press ink colors etc. But I have had every experience dealing with names and colors that everyone here posted and I am convinced some dahlias are just hard headed. I had (the equivalent of) Awe Shucks (from Connells?) bloom last year and it was so YELLOW after the first bloom that I moved it from the orange section to the yellow section this year. So what does it do? It's been every bit the orange I thought it was supposed to be originally. I only moved it 8 feet away - same soil, ground, feeding and watering. I planted a store bought smallish rust orange tuber, planted it in the orange section in the ground and it barely bloomed at all last year. Got perhaps 6-7 small flowers. Color was 'muddy' - not at all what I thought it was supposed to be. So I moved it to a container in the 'graveyard' and this year it has been spectacular. Numerous blooms off a taller plant with rust orange blooms starting out reddish orange. The bottom line (IMHO)is that like others have said, so many factors can affect size, color and hardiness that I suspect few identical dahlias look and grow the same in any 2 gardens. I've learned to be patient (up to 3 years of no blooms even) as long as the plant looks healthy and simply accept what you get. For a color coordinated gardener like me, this advice drives me nuts but it is reality in a dahlia world. Dahlias just aren't like roses which always look like the box! DCR

Do you have any pics? ... I'm with the others, its not a window that I personally recommend, however there may or may not be anything deceptive going on here. As widowmaster alluded to, SDL grids are simply vinyl strips affixed via two sided tape in most cases, with the better manufacturers adding a GBG in the glass. MI may or may not do that part. If they simply field applied the option instead of at the factory, it should be fully warrantied and no worries. You just had the opportunity to "see the sausage being made" so to speak. If OTOH they hacked it up, or if their standard offering does include the GBG "spacer", then you may have a valid complaint and deserve to have it rectified. Are you dealing with an MI factory rep, or just with a dealer that you bought them from? May be time to move up the chain of command.

You DO realize this is posted to a vegetable gardening forum.....?? If you have questions of Houzz admin or the website, then you need to contact them directly, not post to a plant discussion forum.

But my point is, don’t tell people it’s good to 300F degrees when it’s damaged probably at 100F. I’ve tried to get the to change their information so it’s accurate
