Custom Home Construction (Interior Basement Walls)

Interior Basement WallsThe weather turned cold on us but our guys bundled up and worked hard last week getting the interior basement walls built.  The basement floor was poured.  After the floors have cured sufficiently, we start building interior walls.  Following the building plans provided by the architect, enough lumber was delivered to build the interior basement walls.

The contractor has to accommodate for specific energy codes in addition to building codes when ordering lumber and other materials.  This would include the specific size and types of lumber used for specific areas of the home.  For exterior walls, there is a minimum requirement of 2×6 studs to accommodate at least R21 insulation.  Interior walls are usually 2×4; however, some contractors, including Wilkins Contracting, also use 2×6 walls for interior areas where plumbing is located.

All walls will also have a bottom plate and a top plate.  These are used to build walls onto and to join walls where rooms join together, etc.  The size and type of wood used depends on the application and location.  For example, anywhere the wood comes in contact with concrete, you need to use pressure treated lumber.

Pressure treated lumber is a rugged exterior building product that’s rot and insect resistant and necessary to ward off moisture when building against concrete.  Pressure treating is a process that forces a chemical preservative deep into the wood.  The wood is placed into a large cylindrical holding tank and the tank is depressurized to remove all air.  Then, the tank is filled with a preservative under high pressure, which forces it deep into the wood.  This process makes the wood resistant to vermin, insects, and fungus and accounts for its 20 year lifespan even under harsh weather conditions.

Headers were also built above doors and windows.  The size of the headers can be 2×6, 2×8 or 2×10 depending on the size of the door or window.  These are built in to prevent sagging from the weight of the building above these openings.

After the interior basement walls were complete, the floor joists and sub floor for the 1st floor were added.  We used TJI Joist.  TJI joists are the number one brand in the industry and are available with a fire-resistant solution called TJI Joists with Flak Jacket protection.  These joists meet building code requirements for single and multi-family homes.  No special handling is required for these and they can be cut and drilled as needed.

Once the floor joists were added, a ¾” tongue & groove sub floor was glued and nailed in place.  Now we’re ready to build first floor walls.

Next, we’ll be busy building the first floor walls, adding trusses and plan to also have the garage walls put in place.  Keep checking our project gallery for the latest photos of this custom home construction.
