Great Lakes Bayshore Warranty
In terms of its warranty, the Bayshore window includes a lifetime provision on the frame and sash, all of the moving parts such as latches and balances, the fiberglass screen and the insulated glass unit. In the case of the IGU, the warranty is prorated, meaning that the amount of coverage goes down beginning at year 11.
The Great Lakes window warranty is transferable to an additional owner, check with the local company who is selling you the window to find out more on the transfer terms. There are a number of limitations and exclusions that go along with this warranty so as always we urge consumers to read the warranty in full before they purchase these Great Lakes windows.
