If you are okay with vinyl, it should be a decent bit cheaper and if you use a good unit, give you better performance over the 400 option. What do you have available to you up there?

Windows on Washington

I"m ok with Vinyl I am doing all white on the inside and on the outside. I also have two 100 pound dogs that aren't so friendly so I'm afraid of them destroying the front windows when someone comes to the house.

I went to a window store yesterday and he recommended United 8000 series. But I have been reading about a company called Okna.

I live in NY and didn't realize that some companies are not available everywhere.

I am new to this so I'm learning along the way.

Thanks for your response.

Depending on where you are in NY, Okna should be available nearby.
