The mechanicals, HVAC, and plumbing are set and the bones of your home are standing strong. It is time to get some walls in! The first step in this phase is the installation of insulation.
The insulation batts, are fiberglass rectangles that vary in thickness anywhere from 3.5-in thick to 5.5-in thick and are placed within the wall cavities of the house (see right).
The purpose of this material is to keep heat in the home during the winter and to keep the cool air indoors during those hot summer days. For obstacles, like wall outlets and piping, the insulation is split and cut to fit, ensuring full coverage. Once it has been placed and inspected, we are ready for the next step.
Drywall and Taping
This next step is surreal, the drywall installation… these are the walls of your home!
Sheets of drywall come in all shapes and sizes but are generally .5-in thick. In higher fire risk areas, or in areas that simply require thicker walls like the garage, sheets are about 5/8-in thick. The sheets are then placed and screwed into the wall studs at the edges.
Once the drywall is placed, inspected, and deemed secure, the seams are then sealed using a simple, paper tape. This step ensures there are no cracks or crevices in the walls.
Additionally, a drywall compound is smoothed over the top of the tape, helping to make the final walls look flat, seamless, and beautiful. Once the compound has dried, the walls are sanded and cleaned up.
As you can see on the right, sometimes they use stilts to reach those tough areas, talk about wearing multiple hats in your profession!
These walls are ready for primer, paint, tile, and trim!
