(8) Marvin Integrity Double Hung Windows (36-3/4" x 64-3/8") - New/Never Installed. White exterior and include screens. They are for 6" thick walls. Marvin's Integrity series windows are "pultruded" fiberglass exterior (both the sashes and frame are fiberglass) for superior performance (nothing to rot or deteriorate). Both sashes tilt in for easy cleaning. Marvin uniquely bonds wood to the interior so you can paint or stain the wood just like it were an all wood windown. 6 of them have 4 light top sash, 2 of them have 6 light top sash. Do your research - these are arguably the best window money can buy. They are large enough to meet the "egress" code for use in a bedroom (need 5.7 square feet of opening area to meet code). Will sell separately for $500/each (They sell for over $1300 each directly from Marvin).
