When your job (or customer) calls for casement windows, security is always a concern. Not so with our Bertha casement windows that feature a multi-point lock. Our lifetime warranty on all vinyl frames, our limited lifetime warranty on our Truth Hardware with E-Guard, and the Good Housekeeping Seal of Approval, should make you a hero with your customers—providing them with the peace-of-mind that allows them, and you, to sleep at night.
