Walls are more than drywall and paint. Behind the surface is a stack of materials that each do a job.

The Frame and the Skin

Studs form the frame, and sheathing on the outside adds strength and a base for the weather barrier. Siding or brick goes over that.

Windows and doors are flashed into the wall so water cannot get behind them.

Wiring, Plumbing and Ducts

Before insulation, the electrician, plumber and HVAC crew run their lines through the studs and floors. Their work is inspected while it is still visible.

Planning the paths ahead of time keeps the walls clean and the work neat.

Insulation and Drywall

Insulation fills the cavities, and air sealing closes the small gaps that leak. Drywall goes over everything and is taped and finished smooth.

This order is why changes after drywall cost more time, and why we ask for decisions early.
