Typically, capping is done with either a vinyl coated aluminum or using PVC trim coil. Each piece is custom sized and cut using a specialized tool on the job site to fit the window trim. The outside edges are then caulked with a high quality silcone sealant to create a watertight seal. The result is a nice looking exterior window trim that is virtually maintenance free and should last for 20 years or more.
