Balloon frame and Platform frame






Before the utilization of the wood light frame system, severe building was built of heavy timbers, masonry wall.  Balloon frame and platform frame are included light-frame construction. Balloon frame is composed thin, closely spaced, vertical wood components and roof components. The connection between members were made simple nail. Additionally, moving the timber, measuring, cutting with saw and composed the whole members are not need skillfulness. Balloon framing constructed an all side studs which run continuously from top to bottom of a building. This means people use continuous wood for all floor and this studs expensive than other short wood. For this reason, build high rise building with balloon frame is nearly impossible. Moreover; erected a frame is need a lot of man work. In addition, in slabs that constructed with balloon frame method there are some gaps. These gaps allow the passing of voice and air between the floors. These voice cause of the voice pollution and disturb the other people who are dwell other floor of home. Additionally, transition of air hinders the isolation. This event cause to increased energy utilization, hence higher costs. Additionally, the long framing components utilized in construction rises construction costs. Moreover; more labor, skill and specialized equipment is required to lift these walls. It uses long continuous framing members (studs) that run from the sill plate to the top plate, with intermediate floor structures let into and nailed to them.
People use currently most common method of light-frame construction for houses in small commercial buildings is platform framing. In balloon frame, whole frame constructed united piece of frame. However, platform frame constructed floor by floor. That’s means every floor unique piece of whole homes. The technique involved also makes it a quicker method of construction. In the platform frame the subfloor at the first-floor level is concluded later than laying of floor juncture at that level. This subfloor supply a platform for workers to stand on. Additionally, smaller pieces of wood can be used on the wall frames.  Platform frame augment the safety of the workers because they could utilize the floor platform as the scaffold for constructing the subsequent floor. In addition, it became possible to build structures with more than two stories. The technique also requires less labor. With the balloon frame, practical height restriction of the building was two stories because studs longer than two stories were easily available. Platform framing utilizes less wood. This helps to keep construction costs within reasonable limits. No fire stopping is necessary because the stud spaces are enclosed by the floor platforms. In platform frame, between the floors there are platform and it provide isolation both air and sound.
