| The Ostaco 700 Series patio door system, with a host of ?patented? innovations, adds testimony to our commitment to excellence. The Ostaco 700 Series patio door system is constructed using a 5 1/2" multi-chambered clad frame and reinforced sash system, supported by a finger jointed wood buck. These hollow chambers provide you with a very high resistance to the transfer of heat and cold. They keep the weather where it belongs?outside, saving you money on your heating and cooling bills. Since u-PVC resists the effects of weather, it is virtually ?maintenance-free?. It will not rot, rust, corrode, pit, or blister under normal use.
