House building construction methods are trying to check from first! NO.2 let’s compare the construction method of the dwelling

“It probably will check the house making first from construction! With NO.1″ the main construction which is used for the residence was introduced.This time you try to try comparing the feature of those constructions from various angles.

1. Wooden common construction method
About the room arrangement
Wooden framework as for construction method as for the pillar beam and the like the structure is formed in “the point”.Because of that the fact that degree of freedom of the design room arrangement is high, is easy to make the big space and opening is feature.Also future increase reconstruction relatively is easy.

Feature (term of works price and the like) in regard to operation
When foundation in about approximately 4 months, you compare to 2×4 and purehuabu from work to completion, it is the long me.In investigation of the municipal treasury as for average of term of works they are n/a days.
As for price increases at width with the lumber and the facing which are used.If you adhere to the high-class component and the like, that much it becomes high.

safety fire resistance and the like
The person who has the image that it is weak in earthquake, is, but the wood in pulling and is the strong material in compressing.If it reinforces the appropriate place with the muscle intersecting and fire striking and connecting hardware and operates just there is no problem.
The wood is tend to be thought that it is inflammable, but like the pillar is the surface does not burn just carbonizes the lumber which has thickness easily.on the building standards law, although the exterior wall, etc. supposed to use materials which are refractory, by application area is the outer wall of wood is possible.

ventilation, such as insulation and ventilation
wood material is difficult to convey the heat. to enhance the insulating effect by construction without gaps in insulation construction method can be set axis.
well-ventilated take a large window so, natural ventilation can be sufficient. you can make a tree house so health-conscious high humidity conditioning effect.

2.2×4 (two-by-four) construction method
for floor plan
standard size (910?is basic, different by other manufacturers) because the construction of walls and floors and structural materials will be, you may go to a constraint on the structure plan issue because large openings such as drilled in the corner portion of the outer wall can not.

feature on the construction (construction, price, etc.)
· implementation schedule4months the average degree. work is a manual procedure, the constant construction because the dimensions of the member (craftsman) method is difficult to be dependent on the skill of the.
on the other hand, variations in the price is low because it is a unified standard, room for cost reduction is fewer. housing by the manufacturer, there is also a place where low-priced products out floor plans and specifications to some extent has been decided.

safety, including fire resistance
of wall and floor-ceiling surface is configured with, excellent seismic external forces such as typhoons and earthquakes are because they are vulnerable in terms of, non-refractory high moehirogari is difficult due to low gap in the surface structure also. has been certified to the corporation’s semi-fireproof construction.

ventilation, such as insulation and ventilation
-hard to be a gap for the structure that is enclosed in a wall panel, method is highly airtight insulation that is easy to construction without clearance from insulation. because of its high insulation and airtightness24it is often mechanical ventilation time is used.
say sound insulation of the outer wall is high because of the high airtightness, surface there is also a sound surface of the upper and lower floor structure for easy sound that is enclosed in. 3. prefabrication construction method
for floor plan
· the main part of the housing production at the factory, such as roof, walls, pillars and beams, assemble on-site construction method, wood-based structural materials depending on the material of the major, steel system, there is a concrete system, etc.. what type of panel is assembled in2×4 (two-by-four) the strength of the walls and floor will determine the breadth of space in the same manner as. system unit to make room in the factory itself is a special form, such as deformation site is also difficult when the cost is higher. since many are proprietary method, you may not be able to support significant renovation and construction was not a manufacturer.

feature on the construction (construction, price, etc.)
-shortest construction period for a high rate of industrialization, 3months to complete before and after. wood-based94.1day, steel frame system is95.7sun is the average construction. the main components are produced at the factory so, deviation on the true construction is not likely to occur.
prices and unbiased by the manufactureris. minute cost to develop environmentally friendly technologies such as seismic and, there seems to be a trend of slightly higher prices.

safety, including fire resistance
mono type panel technology has been developed by each manufacturer to enhance the strength of structural plywood and adhesives.
to build a prefabricated house, so there is a need to receive the certification of fire resistance, above a certain level of performance has been secured.

ventilation, such as insulation and ventilation
-because it is carried out thorough quality control in factory production, we are focusing on the improvement of both airtight insulation manufacturer.
to take advantage of the characteristics of high airtightness and high thermal insulation and efficient heating and cooling, 24but some, such as ventilation systems and heat exchangers of time the ventilation system has been adopted.

conventional method of construction the building to make by hand, you can also be divided into industrial prefabrication of. what manual are also some crazy gaps and. it is a natural material, alive because. has been industrialization is not the case.
due to the method, the house is most important to the creation of the choice of material.
