Description
- This invention relates to a building element for apartment buildings and detached houses, comprised of a fully or partially covering building panel made, for example, from a plaster and paper mixture, alternatively of glass fiber, wood fiber or cement-based panels to be fixed to wood/steel studs.
- The most traditional way of constructing current pre-fabricated building elements (infill walls and small-house elements) is a wooden frame with partially broken thermal bridges and a traditional mineral wool, glass wool or, alternatively, cellulose insulation. The wall thicknesses vary up to passive house structures of 500 mm. Besides, the structure is lined with a wind barrier panel/board externally and with a moisture barrier (plastic foil) internally as well as with a cardboard-lined plaster panel. Air leakage levels of 1,5 l/s·m2 - 0,04 l/s·m2 are not unusual. Further, the current construction method replaces the organic materials with inorganic material, such as steel and cement-based panels or some other inorganic panel material. All this in order to achieve a maximally moisture and mold resistant building envelope (wall structure) but still with air leakage.
US 6 279 284 B1 andGB 546 684 A WO 02/22975 A1 - The invention is characterized in that the panels are fixed to the studs by double glue lines with screw or nail joints between the glue lines according to a NO building system, whereby the method results in airtight cells throughout the building element.
- The invention relates to an entirely new logistics, assembly and building system giving the client: a logistic and climate-adapted building envelope where air, diffusion and wind sealing is of great importance for a building in terms of energy consumption, moisture security, thermal comfort and hygiene, air quality, sound environment, spread of fire and entry of air pollutants from outside. Airtightness is a critical factor both for the durability of the structure and for a good indoor environment in modern buildings. In the long run, airtight houses are also profitable for the actors involved. In the end, for nature as well. Research shows that the heating energy consumption of a house is reduced by almost 30 % if the airtightness (the air permeability, actually) is improved from 0,8 l/s·m2 to 0,4 l/s·m2. According to this invention, the client obtains an actual air permeability of 0,01/s·m2. Such a great decrease in energy consumption is probably not achieved through any other energy improvement measures.
- The dependent Claims set forth different embodiments of the invention.
- An airtight wall element consists of NO classified wood/steel studs of 45 x 45, for example (the dimension of the studs may vary depending on the dimension of the air gap/cell), as well as of NO classified organic or inorganic panel material of 6 mm to 13 mm in thickness. The constructor may determine the wall thickness and the number of wall elements needed based on the required wall-structure U value. All of the screw or, alternatively, nail joints are placed along the longitudinal center line on each stud included in the element, the junction between a vertical and a horizontal stud should be provided with a glued joint. Tight double lined glued joints should be applied between each panel surface and stud surface, whereas screw or, alternatively, nail joints should be placed between the glue lines, using a C/C distance which may vary depending on the substrate, provided that the requirement on airtightness is met. A stud-stud and panel interspace forms an airtight cell.
- The end result is a building envelope where air, diffusion and wind tightness is of great importance for a building in terms of energy consumption, moisture security, thermal comfort and hygiene, air quality, sound environment, spread of fire and entry of air pollutants from outside in a building. Airtightness is a critical factor both for the durability of the structure and for a good indoor environment in modern buildings. In the long run, airtight houses are also profitable for the actors involved. In the end, for nature as well. Research shows that the heating energy consumption of a house is reduced by almost 30 % if the airtightness (the air permeability, actually) is improved from 0,8 l/s·m2 to 0,4 l/s·m2. According to this invention, the client obtains an actual air permeability of 0,01/s·m 2. Such a great decrease in energy consumption is probably not achieved through any other energy improvement measures.

Figure 3 shows a NO building system airtight "Singel + Singel" where two single elements structured as above but, on the contrary, connected in parallel can be seen. No thermal bridge break.

Glued and screw/nail joints made according to NO building systems.Density 59 kg/m2 V thickness 225 mm - NO building systems create new conditions for achieving a controlled airtightness in apartment buildings and detached houses in a controlled, practically applicable way.

- NO building systems can, thanks to their shear stability and light structure, be transported and handled with a moderate truck and crane capacity. The built-in internal stability of the wall system helps it to maintain its dimensional and fitting accuracy.
- The new inventive product NO wall system can be treated using a "WSJ" treatment method leading to an entirely new technique of installing building structures, such as walls including organic building material.
