The framing for the new wall in the bedroom is almost complete. This wall is being erected in the same spot the builder had originally installed a wall. You are viewing the new model railroad room's "extension" from the master bedroom.
Almost all of the insulation is in the wall. Why insulate an interior wall? Noise reduction into the master bedroom.
Drywall has been installed on both sides of this new wall. This is the view from the master bedroom.
Joint compound now covers the drywall gaps and screw heads. This shows the view from the model railroad room. After this photo was taken, the master bedroom wall was painted to match the rest of the room, and the carpet installation was finished.
This photo shows the walkway between the two rooms, also refitted with drywall.
The new stub wall in the main model railroad room has been completed. It will provide support for the cabinets and the layout benchwork as it curves around this wall. The wall consists of two standard interior walls made out of 2x4's. These walls are spaced 13 inches (33 cm) apart so that the total wall width comes to 20 inches (51 cm). Horizontal braces were installed to keep the walls straight and at the right distance from each other. This wall will not be covered with drywall because it is going to be completely hidden when the cabinets are in place. The photo view is from the room's main entrance. I added 1/4" bolts to the horizontal braces (which were simply nailed in place), because the boards kept on popping as the temperature changed in the room. Quite an annoying noise in an quiet house. Once the bolts were installed, all the noises disappeared.
I filled in all the holes in the floor left by removing the carpet tack strips. Then the walls and ceilings were painted with "Ultra Bright White" latex paint (several coats). The photo shows one wall in the main room (entrance on the left) that is painted with "Charcoal Smoke", which is a very dark green. I chose this color, because it is the color with which the valances and layout fascia panels will be painted. This wall will not have any model railroad cabinets, so I wanted to create a cohesive whole with the layout.
