When making your shed drawings consider using polyvinyl chloride as a convenient material for your outbuilding. PVC is the most manufactured plastic for constructing and construction products. Windows made of vinyl became popular during the energy crisis of the early 1970s in the US. Polyvinyl can be molded easily into almost any shape and any design specifications. Windows made of vinyl require very little maintenance and never need to be sanded or painted. Compared with other window materials polyvinyl windows are great thermal insulators.

The use of a mudsill is to rest it on your foundation and build the frame over it. Floor joists rest above the mudsill to support the outbuilding's walls while the band joist closes it off from the outdoors. You can use plywood floorboards that are ¾ inch thickness to lie down atop the mudsills and joists. Never use plywood thinner than ¾-inch because the floor will flex between joists. To increase the firmness of your floor invest in grooved plywood that fastens together. Fasten down the plywood with 2-inch long galvanized decking screws.
