I concur with Scott Design. Go back to manufacturer or where they were purchased and they will have what you are looking for...

How do you decorate your place, what kind of style, colors, and feelings? That will greatly influence the type of door you might want. Also, think of your budget, and whether you want to install it yourself or hire a professional (you don't need to tell us, just keep that in mind). Then look around Houzz, in the products page, they have lots of interior sliding doors and hinged ones, from elegant frosted glass in a dark wood frame, to rustic reclaimed wood planks. You may not want to purchase that exact model, but it might give you a better idea of what would fulfill your airflow needs without sacrificing style.

Also it is not necessary to go for uPVC. I am preferring uPVC because it looks good. Any other good looking options are also welcome

Flush doors are the most simple doors available in the market and their simplicity is what makes them so widely popular. They have a smooth, flat surface and do not have any detailing on them. Choose a veneered flush door, in case if you wan to add more beauty to their simple & charming look. CenturyDoors have a beautiful collection of doors & also you can go for greenply doors. It might be a little costly option in comparison to locally made, but if you can go with branded you'll get quality along with highly secure & durable interior doors.
