the constructive aspect PIU 'INNOVATIVE PREFABRICATED HOUSES AND' THE PARTICULAR CONSTRUCTION OF THE WALL THAT IS MADE OF WOOD STRUCTURE IN A PACKAGE THAT INCLUDES VARIOUS MATERIALS.
Hello. I wanted to propose a theme which I think has not been thorough in his blog and that is that construction techniques related to the walls. I have proposed the construction of walls with the technique to "truss" in what seems to be (as shown by her in the blog) the most economical and practical to implement. I'd love to hear his detailed opinion on the subject and would be equally interesting to know and compare the other techniques used in manufacturing prefabricated wooden houses .
The external wall of prefabricated houses is certainly the most innovative and interesting which allows timber houses energy performance of relief, with wall thicknesses kept to a minimum.
This is a theme widely Treaty, to which I refer to the reading of the articles already published on the subject, as prefabricated houses massive wall through the use of xlam so-called, or analysis of the lattice walls (or platform flame - balloon frame), which for many years have established themselves as a true standard for prefabricated houses, thanks to their low cost, excellent resistance to static and 'high level of insulation to get to.
architect Hi, I wanted to ask advice about the different types of walls that are taken to the prefab houses.
I understand that the materials used to "fill" the walls are rock wool, wood fiber and cellulose . I could not find the network unbiased opinions about these three types, so I would ask, what are the pros and cons of these elements? wood fiber worries me that they can mold to form 'inside because of an incorrect treatment moisture. Especially I wonder, do you want the cellulose, you want the wood fiber, with the passage of decades does not "ground", do not lose their original texture, in fact there is a danger of a breakdown in internal walls?
the market for prefabricated houses , in particular for products traded in our country, has established a gradual shift from mineral wool the wood fibers. are now rare wooden homes with fiberglass insulation (material with excellent insulating capacity, but with less mass and therefore less performance than the hot summer). The fiberglass also has a tendency to lose consistency and sag over the years, so it would certainly be a material to be discarded.
The rock wool, on the contrary, an insulating material is ideal in many ways. Its mineral composition makes it resistant to insects, molds, fungi . insulating capabilities are very good and has good durability. E 'right to a good natural insulator that falls right in between the products used in green building .
Nevertheless the tendency of manufacturers of prefabricated homes is to supplant the rock wool fibers with high-density wood, since the thermal inertia of a lattice wall (whose thickness is difficult to exceed 30 cm) depends largely on mass insulation placed between the wooden posts . Rock wool is a light, little to protect food from the summer heat, typical of the area. The walls of the prefabricated houses based on this material the values \u200b\u200bof the phase shift of less than those involving a wood-fiber insulation, much more suitable and efficient, even with winter insulation values \u200b\u200bcomparable to the mineral wool.
The high-density wood fiber used in prefabricated houses is a natural product, very stable and difficult to attack (because adequately protected in the package wall), made by pressing the remains of the sawmill, in the form of cuts discarded and chips, without added binders and free from harmful substances, easily disposed of through recycling, composting or combustion.
The mass of wood fiber reveals an excellent acoustic behavior in prefabricated houses, not only for the noise transmitted from the air, but also those caused by traffic and the sound absorption in all frequency ranges.
