Retro Windows come with great guarantees because they are made to last! They are constructed from hollow, multi-chambered, high-impact resistant polyvinyl chloride that won't warp or fade over time. All component parts are made from painted aluminum or stainless steel to resist corrosion. Reinforced vertical and horizontal mullions add structural stability and strength.
