What is the window sill?

Sill plate or MUDSILL is a plate that is placed horizontally above the base of the building. Vertical members of framing called studs can then be built on top of the sill plate, which is anchored to the concrete foundation. This allows a flat, even surface for framing construction and a buffer between framing and base. Since the concrete tends to release moisture, the lumber treated may help prevent the rot of the studs. Usually the plate is anchored to the foundation with an anchor screw, a large screw with a hook or an expansion wedge at one end and threading for the nut at the other end. The culminated end of the screws is located at the measured intervals in wet concrete and on the left, while the base solidifies. The holes are then drilled into the window sill at the same intervals, so when the board is found, the anchor screws pass through the holes. The matrix can then be screwed to the threaded end of the screw, usually using a tool called the impact controller.

Today, many houses also have a seal of polyethylene foam, which sits between the window sill and the base. This prevents moisture from passing through concrete or ground and rotting on the window sill. Usually, however, the foundation is built above the finished degree or upper surface of the Earth, so the board does not come into contact with the soil or lawn. This helps to protect wood from thermit and rot.

Sill plates are often processed pressure to prevent insect and moisture damage. Pressure treated wood is wood that has undergone the process of placing in the tank, depressive and then suppressed by preservative chemicals. This is pushed by a preservative that is resistant to moisture and insecting on insects, thoroughly into wood. The chemicals that have been most used until recently are chrome -arsenic of copper (approx) very toxic and is now replaced by less toxic alternatives. Buildings that already have approximately treated window sills or other wood members are considered safe and deletingToo of these boards can release more toxins than let them leave.

Another purpose of the window sill is to create a framing platform. Since the concrete is uneven, it would cause the pins to reach different heights if they were all cut into the same length and mounted directly onto the base. If the concrete has been poured well, the window sill can simply be laid, but if the concrete is uneven, the pads can be placed under the board. Sim is a piece of wood in the shape of a wedge or other material that raises the plate in place, so it is at the level. Edies can then be anchored to the sill plate by different methods, depending on the architect.
