zeb Posted July 28, 2007 Share Posted July 28, 2007 Hi, if you were renovating an open space which is 3 mtrs high at its lowest point rising to 6 mtrs at the apex, into 5 rooms and retaining the height (insulation beneath the new roof tiles and inside joists insulated and plasterboarded between) a) what would you use for the interior walls, and b) does anyone know what French regs are for this sort of project? As a disclaimer - we normally always use metal rails and understand the problems with humidity, insects etc if using softwood wood. But, on this occasion we have small concerns about rigidity.

Gastines Posted July 29, 2007 Share Posted July 29, 2007 Interlocking metal rails will at least give you a plumb 6mtr wall. A bit of a problem with soft-wood studding. As stated before off-set joints on double boarded walls will give you a fire break and the wall,extra rigidity.Regards. Link to comment Share on other sites More sharing options...
clarksinfrance Posted July 29, 2007 Share Posted July 29, 2007 It is possible to buy the metail rail and montant in various flavours, ie Leroy Merlin do 48mm & 70mm, the 70mm is so much stiffer. Link to comment Share on other sites More sharing options...
Dave&Olive Posted July 29, 2007 Share Posted July 29, 2007 hiok not going down the wood v metal route , but on long lengths on external walls just bend a bracket screw it to the back of the montant so it`s just shy or touching the wall and throw a big dollop of plaster on it this glues it to the wall when it sets .are there french regs ???for soft wood use chevrons are not these treated ???
