Clad windows are blessed with an exterior coat of armor. This is a viable option for homeowners who love the look of wood windows, but hate the maintenance and cost of replacing warped or splintered wood. Wood windows are clad, meaning covered, with metal (usually aluminum), vinyl, or fiberglass on the exterior frames.

Dog clutch. A dog clutch is a type of clutch that couples two rotating shafts or other rotating components not by friction but by interference. The two parts of the clutch are designed such that one will push the other, causing both to rotate at the same speed and will never slip. Dog clutches are used where slip is undesirable and/or the clutch is not used to control torque. Without slippage, dog clutches are not affected by wear in the same way that friction clutches are.
