The window company I used went out of business and several of the grills have broken. I'm looking to replace some or all of them. I'd like to see the product you make or at least a description of it. I've got 13 windows, standard sizes that I'll have to measure but I think about 8 are 30w by 42H and the others are 30W by 48H I think. any advice or guidance would be helpful.. Matt
