The 6000 series is our most popular model. Both master frame and sash frames are fusion welded and are guaranteed to last for a lifetime.

Since the 6000 series will meet or exceed all requirements for the new stimulus tax credits you are actually getting the upgrades to this model and the Energy Miser glass package at no additional cost after tax credits. That's what makes the 6000 series a very popular choice.
