Went to the Serious Website and the site then links to "Kensington". It shows they no longer make fiberglass windows and only make vinyl.

Did they get bought out or did something else happen? Why did they eliminate the fiberglass line?

You posted in this thread discussing the sale of the fiberglass window line to Alpen:

Recent news regarding the vinyl line:

That thread was back in October 2012 and the article you linked shows the recent change to have occured in March 2013 with an article publish date of April 2013. So if I understand this correctly. Serious is out of the vinyl window business and is only making aluminum commercial windows. Kensington now operates the former Serious vinyl residential window division but doesnt make fiberglass as that was taken over by Alpen. So now Alpen and Serious both use the heat mirror technology.

Alpen took over manufacturing in the last summer early fall of 2012; we were in the middle of an order

So what happened to the order? These were fiberglass windows with the heat mirror/ suspended film?
