E X T E R N A L W A L L S T R U C T U R E01 EXTERNAL WALL STRUCTURE1.1 With wood cladding and soft insulation12 341413125111067981234562-layer insulation panel construction is recommended to avoidnegative effects caused by possible jointsE.g. vertical interior laths if the rear ventilation laths runverticallyInsulation material of choice - in case of high fire protectionrequirements we recommend rock wool. Otherwise alsohemp, cellulose, soft fibre or similar are possible. Insulationpanels can be soft - the cladding supports the load ofthe facade (permanent vertical loads, wind loads)Taping of the joints in the ceiling area - depending on thesize of the joints (wind-sheltered area)KLH wall and ceiling elements depending on static requirementFor heavy facades insert screws at an angle - the facadeshould be statically proven (wind, facade weight)7891011121314Concrete foundationExtend sealing over the horizontal jointBase insulation according to the requirements - e.g. XPSinsulation in the splash-water areaWindproof and water-repellent layer dependent on thedesign of the facade. The more open the facade the moreimportant is this layer - with open joints take the UV resistanceinto accountScrew connections depending on the static requirement -watch for wind suction in the corner areaE.g. wood facadeWith pre-fabrication of the facade construction we recommendthe subsequent installation of the insulation in thejoint areaTransverse laths as an intermediate structure0 4

Joints,e.g. between shower tray and tiles (silicone joints), aremaintenance joints and have to be checked regularly!E.g. tiles on plasterboard panels (suitable for wet rooms); insplash-water areas (bath tub and shower areas) with additionalsealing layer between the tiles and the plasterboardpanels (also in the floor structure: horizontal sealing underneaththe tiles - the seal behind or underneath the tiles isnot shown in the drawing)Mounting of the pipes is acoustically insulated4567Pull the seal layers into the installation shaft – in the eventof water damage this can be detected on the underlyingshaft wallSingle seal layer - directly on the KLH solid wood panelDo not screw the pipes to the ground! Possibly tape to theground and fix with bundled filling material!Suspension of the sealing layer on all sides - even in thedoor area2 1
