Modular Home Construction
Modular Home Construction Options
Modular Home Floors - The floor system of a modular home is constructed on a jig to make the floor square. The floor system is constructed of with 2x8, 2x10 and 2x12 lumber with either plywood or OSB (oriented strand board). The floor system of a modular home is often over looked as a potential option upgrade. Some modular home factories offer the thinnest floor decking available and others offer a double layer of floor decking.
Modular Home Walls - The walls of a modular home are constructed of 2x6 so walls can be insulated to local and state building codes. Exterior walls in modular homes are sheathed with wood sheathing. Often tract builders will only install cardboard sheathing or rigid insulation board as the primary sheathing on their home.
Modular Home Cieilings - The standard height for a modular home ceiling is eight feet tall. However you can upgrade your ceiling height to upto ten feet depending on your location in the country. In addition to flat ceilings, you can upgrade to cathederal ceilings, vaulted ceilings, tray ceilings and dropped soffits and bulk heads for your modular home ceiling,
Moudular Home Stairs - Modular home stairs for two stoyr modular homes are installed at the factory. The stairs can designed a single run stairs, split stair way systems of almost any stairway configuration that will fit your prefab homes design. In addition to stair ways, one must consider stair rail styles and installation.
Modular Home Strapping - In addition to walls, ceilings and roof systems being nailed, glued and lag bolted, modular home components are also strapped together for additional strength. Steel strapping is used to strengthen the connection between the modules for transporation and set.
Modular Home Cantalevers - A cantalever for a modular home allows a home to have additional dimensional appeal. The most common cantalever in modular home construction is used on raised ranch modular homes. The cantalever can also be used on two story, Cape Cod floor plans and modernist modular home designs.
Modular Home Garages - Modular home garages can be constructed at the fatory or they can be built on site. If your home floor plan has an integrated garage, the modular home company will build the garage in the factory. Free standing or detached garages are often best built on site.
Modular Home Roofs - Modular home roof systems fold down for transportation and are raised and secured into position after the home is set on the foundation. Modular home roofs can have low roof pitchs - moderninst floor plans to steep Cape Cod roof pitches of 12/12. In addition to standard gable roofs, modular homes can have flat, mansard roofs, gambrel and hip roofs. Another elementt of modular home roofs are dormers.
Modular Home Module Layouts - Modular home modules can be "pieced" together to form almost any shape. In addition to being laid out in multiple configurations, the modules for modular homes can also be stacked upon each other. The design of your modular home will dictated how the modules are placed and stacked together.
Modular Home Bumpouts - Modular homes with bumpouts have additional curbside appeal. A bumpout can be connected to the main box or it can be constructed as its own module. Bump outs on a modular home can also add dimension to the interior of the home. Breakfast nooks, home offices and living rooms benefit with additional depth or special spaces with bumpouts on a modular home.
Modular Home Wedge Boxes - A wedge box for a modular home is a finished roof box for a Cape Cod floor plan, a bonus room over a gagage, cathederal or sloped ceilings in modular homes. There primary benefit to a wedge box is additional finished space from the factory. Depending on your home's design and your requirements will influence if your home is constructed with wedge modules of boxes.
Modular Home Construction Options
During the design stage one should consider the construction options for their new modular home. Construction options include the floors, wall, ceilings and roof system. Often overlooked is the floor system when a modular home is being priced out. When it comes to the walls of the home, many people feel sixteen on center framing is required to make a good home. The ceiling system of a modular home might be the most radical difference between a site built home and a modular home. Modular home factories use both truss systems and rafter systems, depending on the prefab home factory.
Modular Home Roof Pitches
Roof pitch on a modular homes makes a major difference to the overall appearance of prefab homes. To the left you will see a 3/12 roof pitch and on the far right is a 12/12 roof pitch. 3/12 roof pitches are common on manufactured homes or double wide homes. The unit in the middle below has a 7/12 roof pitch which is a common roof pitch for most modular home factories. The 12/12 roof on the far right is the standard on modular cape cods.
The advantage of having a higher roof pitch on a modular home include: appearance and the opportunity for a storage attic or additional living space.
Modular Home Roof Framing
There are two types of modular home roof framing systems: trusses and rafters. Modular homes incorporate trusses and rafter systems into their homes roofs. Both the rafters and truss systems "fold" down to accomodate delivery route height restrictions. Some modular home factories construct wedge boxes - A wedge box for a modular home is usually a finished space with a steep roof pitch - 12/12 - often found on cape cods.
