Wood Frame Construction
Phase 1: Framing and Ventilation
There are two methods you can use to construct a wood-frame house. We used the most common method, which is the Platform method. It is important to note that the amount of time if will take for you to complete the framing for your home will depend greatly on the weather conditions. Unpredictable weather conditions can delay your schedule for days and weeks, so be prepared to adjust your plans.
The structural shell of your home will need to be put up, and this shell consists of the foundation, floors, walls and roof. Once these are in place, you can start to think about the level of insulation you will use in the different parts of the structural shell, since framing dimensions will need to be adjusted depending on your needs. Below is some more information about the two methods used:
- Balloon Method: With this method, the studs used for the exterior and interior walls are, which means that site assembly is not easy.
- Platform Method: With this method, the floor is built separate from the walls, which means you can have a sturdy solid surface to work off of. This makes putting up the walls and partitions easier. Also, the studs are only one storey high, which means that calls can be easily premade or put together on the subfloor, and erected one story at a time.
After we use the platform method for your shell framing, we then started our floor framing, which used headers, sills, joists and beams. We made sure to have seasoned lumber for this, since we want to control moisture as much as possible. You should check with your building codes to see what moisture content is acceptable for the lumber you will use with your floor frames.
When constructing the walls frames, this will include creating the vertical and horizontal members for exterior walls and interior partitions, also known as studs. These studs are the nailing base for all covering materials and support of the upper floors, ceiling and roof. Roofs can either be flat or pitched, and the slope of the roof varies depending on the house design. Pitched roofs will typically have more of a slop, where has flat roofs will have less of a slope. A roof slope of 1:1 fits with our healthy housing principles.
No matter which roof type you will use, ventilation needs to be incorporated into the plan. Proper insulation needs to be provided in the roof space above the insulation. If water or moisture builds up in spaces in the roof, it can lead to damage in areas where the moisture accumulates. This is especially during in cold weather. The size of the vent you will choose depends on the slope of your roof and the way the roof is constructed. In any case, the vents should be evenly distributed on all sides of the building.
