AN INTERNAL NON-LOADBEARING WALL FOR A BUILDING SYSTEM
USING TIMBER FRAMED CONSTRUCTION FOR HERITAGE HOUSING
DESCRIPTION
The present invention relates to an internal non-loadbearing wall for a building system for heritage housing and particularly but not exclusively to a building system using a timber framed approach for non-loadbearing internal walls prefabricated from four different horizontally spaced apart layers of construction (the two outer layers repeat on each side of the wall to give six actual layers).
Internal non-loadbearing walls are walls which are used to define room boundaries internally within a single occupancy building. They extend from the ground floor base up to the first intermediate floor and from the structural intermediate floor deck to the next of the upper floors and so on up to the roof level. Internal non-loadbearing walls must be designed to satisfy a number of different requirements in order to function adequately in service and also to meet the various requirements of building regulations, codes and standards, acceptable good practice and client needs, typically related to fire safety, sound insulation, robustness and general serviceability.
There are Internal non-loadbearing walls currently in use which meet these design requirements.' These walls use timber, steel or concrete as the main structural material together with various other layers of materials. For framed systems, in many cases part of the wall is prefabricated, usually the basic frame part of the wall comprising the vertical studs and horizontal rails with mid height naggings in some cases. There are no examples known of fully prefabricated closed panel wall systems which comprise the studs and rails with outer linings to the faces and acoustic insulation in the frame space and, which provide an enhanced level of robustness in terms of resistance to internal impact and the ability to make internal fixings without additional support in the form of naggings.
An object of the present invention is to provide an internal nonloadbearing wall which is fully prefabricated away from the place where the wall will be used, which meets all the minimum building regulation and good practice requirements and also provides enhanced sound insulation and a greater robustness compared to conventional walls. The high level of prefabrication is in order to increase; the speed of construction on site, to reduce on-site defects and to increase the quality of the construction. The enhanced sound insulation is to provide improved occupant comfort. The improved robustness is to provide occupants with an enhanced feeling (and actuality) of solidity and to reduce costs and defects associated with provision of support for fixings to internal surfaces. '
According to the first aspect of the present invention relating to the internal non-loadbearing wall part of the system, there is provided in the wall a first outer layer (on both sides of the wall) which is known as the outer lining.
The outer lining layers normally have at least four functions: o Provision of a level of resistance to moisture to prevent damage from wetting during transport and assembly of the prefabricated wall panels.
a Provision of a substrate for decorative finish.
a Provision of a surface spread of flame classification.
O A contribution to sound insulation as a "mass" component.
Preferably the outer lining layer is comprised of a non-combustible, high mass board material with a Class 1 or Class O surface spread of flame classification to the surfaces on either side of the wall facing the rooms, which is suitable for decoration. Preferably the board material comprising the outer lining layer has a level of resistance to moisture to prevent damage from wetting during transport and assembly of the prefabricated panels. The internal lining layer is fixed to the second outer layer. The outer lining could be moisture resistant plasterboard. According to the second aspect of the present invention relating to the internal non-loadbearing wall part of the system, there is provided in the wall a layer second from outside to the outer layer (on both sides of the wall), which is known as sheathing layer.
The sheathing layer normally has at least three functions: o A contribution to sound insulation as a "mass" material.
a Provision of the key resistance to impact damage (robustness).
a A contribution to,the ease of fixing services and fittings to the external walls (robustness).
The sheathing layer should preferably be a board material which is moisture resistant and is of high density. The internal sheathing layer could be oriented strand board, Shipboard, plywood or solid timber boards but other materials may be equally used.
l According to the third aspect of the present invention relating to the internal non-loadbearing wall part of the system, there is provided in the internal non-
loadbearing wall a layer third from the outside face which is known as the support frame spacing layer.
l The frame in the structural frame spacing layer normally has at least two functions: o Provision of support to carry the sheathing layer.
a Provision of space to fit the acoustic insulation.
Preferably the support frame is comprised of vertical studs and horizontal rails of a size suitable for fixing the sheathing layer and to provide space for insulation suitable to meet the required acoustic performance. The said studs and rails are preferably of solid timber.
According to the fourth aspect of the present invention relating to the internal non-loadbearing wall part of the system, there is provided in the internal non-
loadbearing wall a layer, also within the support spacing layer which is known as the acoustic insulation layer fitted in the spaces between the studs and rails. The acoustic insulation layer normally has only one function: o A contribution to the sound insulation as an absorbent layer.
Preferably the acoustic insulation layer is an open-cell insulation material which is fitted tightly up to the sides of the frame so that it forms a continuous vertical layer in all of the spaces between the studs and rails. A typical acoustic layer could be mineral wool insulation of a density of at least 40 kg/m3 but other materials may be equally used; open cell semi rigid materials of higher density or Clown cellulose type products, all to fully fill all of the frame cavities.
According to the fifth aspect of the present invention relating to the internal non-loadbearing wall part of the system, there is provided a method of manufacturing and installing an internal non-loadbearing wall which comprises: o The provision of all six layers (two of which repeat on either side of the wall) of the internal non-loadbearing wall, for prefabrication of said wall at a place away from the final position of installation into a building, as one or more complete six-layer panels to make up the said internal non-
loadbearing wall.
a The one or more complete panels of the internal non-loadbearing wall are taken from the place of manufacture to be assembled into final position in a building; said panels remaining complete as six-layer panels during this transport and installation phase. In one example of this phase, the complete wall panels could be lifted by crane from the place of manufacture onto a lorry, transported by lorry to the building site and lifted by crane into final position in the building.
a The one or more complete panels are installed in the building and joined to the foundations or the intermediate floor and to each other, all as necessary to make the designed connections for acoustic performance and robustness.
Preferably the method of manufacturing and installing the internal non-
loadbearing wall includes providing one or more of the features disclosed in the above paragraphs relating to the first to fourth aspects of the present invention relating to the internal non-loadbearing wall part of the system.
Embodiments of the present invention will now be described, as one example only of the internal non-loadbearing wall with reference to the accompanying drawing Figure 1 which shows a plan section of the internal non-loadbearing wall.
With reference to Figure 1 one embodiment of an internal non-loadbearing wall in accordance with the present invention comprises the following: o An outer lining layer (1) of 15mm moisture resistant plasterboard fixed to each side of the wall to the sheathing layer.
a A sheathing layer (2) of 1 5mm oriented strand board, OSB-3, in accordance with BS EN 300 fixed to the timber framing on each side of the wall. a Solid timber framing (3), 63x38mm, strength class C16 with studs at 600mm centres.
u An acoustic insulation layer (4) which is rock wool semi-rigid batts, with a density of 50 kg/m3, fitted tightly into all frame spaces.
