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.

The clutch allows us to smoothly engage a spinning engine to a non-spinning transmission by controlling the slippage between them. To understand how a clutch works, it helps to know a little bit about friction, which is a measure of how hard it is to slide one object over another. Friction is caused by the peaks and valleys that are part of every surface -- even very smooth surfaces still have microscopic peaks and valleys.
