4 Page 4 - European Technical Approval ETA-05/0022 II SPECIFIC CONDITIONS OF THE EUROPEAN TECHNICAL APPROVAL 1 Definition of product and intended use 1.1 Definition of product WeberHaus buildings are predesigned and prefabricated timber frame building kits for individual houses including external walls, internal walls, floors and roof. Every building element is pre-assembled in the factory including doors and windows and eventually completed with external and internal finishes. These elements are then assembled on site on an existing concrete base slab or on top of the basement floor (see fig. 1 Annex 1). Every building element (wall, floor and roof) is described later on as well as the assembly principle. All the materials data are given in Annex External wall See Annex 4A There are 3 configurations for the external wall : WA 01 with an external rendering. WA 02 with an external wood cladding. WA 03 with an external brick cladding. All 3 are based on the same structure and insulating system with the following components (from outside to inside).

7 Page 7 - European Technical Approval ETA-05/0022 The design of the roof (slope, ventilation section, protection against driving snow ) can be adapted case by case depending on national requirement Fixing devices All connections are detailed on the cross sections in Annex 4 as well as the different staples or screws to fix the boards on the timber frame. 1.2 Intended use The intended use for the building kits is a single family house of maximum 1 storey, with or without basement. The roof space is intended for living purposes. The building kits are to be used in European countries. The timber is not treated against termite attacks. No performance has been determined regarding the seismic action. The anchors to the substructure are designed case by case according to their own ETA.

8 Page 8 - European Technical Approval ETA-05/ Characteristics of product and methods of verification 2.1 Mechanical resistance and stability (ER1) The mechanical performance of the building elements was determined according ENV : The mechanical data corresponds to : Solid wood: EN 338 / EN 385 Particle board: EN 312 Staples : german technical approval Nr Z and Z The characteristic load capacities of the building elements are presented in Annex 2. No performance has been determined on the complete building elements. The design shall be performed case by case. No performance has been determined regarding the seismic action. 2.2 Safety in case of fire Reaction to fire The classification of a certain range of components has been given with material data in Annex 3. No performance has been determined on the complete building element Resistance to fire For the external wall, resistance to fire is based on a full scale testing: classification is given according to EN External wall : REI 30 For the floor, resistance to fire is given on the bases of a calculation according to Eurcode ( ). Floor : R15 No performance determined for the roof External fire performance of roof covering According to the commission Decision 2000/553/CEE, the concrete tiles and clay tiles are deemed to satisfy all the requirements regarding the external fire performance without further testing.

9 Page 9 - European Technical Approval ETA-05/ Hygiene, Health and Environment Vapour permeability and moisture resistance The design of the building elements and the experience on site, brings to the fact that there is no risk of interstitial or internal condensation in case of current humidity flow from inside towards outside. The condensation risk has not been determined for southern countries with cooling devices where the humidity flow could be from the outside towards the inside Watertightness The standard construction details allow to assess the watertightness of the building envelope favourably. Regarding the watertightness of internal surfaces of wet areas, the performances depend on the floor and wall finishes which are note part of the kit. Some technical solutions are implemented in WeberHaus documentation. It has to be evaluated case by case depending on the real construction details on site Release of dangerous substances Based on the declaration of the manufacturer, the WeberHaus buildings do not contain harmful or dangerous substances as defined in the EU database, with exception of formaldehyde. In addition to the specific clauses relating to dangerous substances contained in this European Technical Approval, there may be other requirements applicable to the products falling within its scope (e.g. transposed European legislation and national laws, regulations and administrative provisions). In order to meet the provisions of the EU Construction Product Directive, these requirements need also to be complied with, when and where they apply. 2.4 Safety in use Slipperiness of floor finishes Due to the large range of possible floor finishes to be installed in the house, the performance has not been determined. The slipperiness has to be evaluated case by case where national requirements are applicable Impact resistance For both the external wall and the floor, the thickness of the particle board and the space between the timber corresponds to well known construction details. The impact resistance is then assessed positively without testing for the intended use. On the inner side of the external wall and partition there are both a gypsum plasterboard and a particle board which limit indentation marks eventually due to hard body impacts.

Building element R Value U Value (m².k/w) (W/m 2.K) WA ,25 External wall WA ,30 WA ,26 b (mm) Floor DE x x Floor DE 02 2 x b (mm) x x x Roof DA ,21 Windows / doors < 1,5 Attention has to be paid to the fact that calculations were performed with tabulated values for thermal conductivity either from EN or from

11 Page 11 - European Technical Approval ETA-05/0022 CE marking of insulating materials. Those values do not take into account eventual increase to be applied in accordance with national regulations Air permeability The current construction details shown in Annex 4 present the continuity of both the internal vapour barrier and the external breather membrane. The kit is then providing sufficient airtightness to be in accordance with the intended use Thermal inertia On the basis of density, specific heat capacity and thermal conductivity presented in Annex 3, the surface thermal capacity of every building component is declared for a period of 24 hours in order to determine the thermal inertia for each building. Building element Surface thermal capacity in kj/(m²k) External wall WA01 Internal 35.5 External wall WA02 Internal 35.2 External wall WA03 Internal 34.8 Internal wall WA04 Internal 31.7 External 31.7 Roof Internal 15.6 Floor DE01 Upper side 80.5 Lower side 21 Floor DE02 Upper side 80.3 Lower side Aspect of durability The external finishes are not assessed in the framework of this ETA. The systems shall comply with the relevant technical specifications. The timber species is in natural durability class 4 concerning fungus attack and class S concerning insect attack according to EN Structural components are in hazard class 1 according to EN Protection against corrosion of the fasteners of building elements is corresponding to service class 2. The fasteners for external cladding are in stainless steel.

12 Page 12 - European Technical Approval ETA-05/0022 The assumed working life of the house based on the description of the components on general knowledge of timber frame building and on a regular maintenance is : 50 years for the building (structure, insulation, boards, ) 25 years for the external finishes as well as windows or doors. 2.8 Aspects of serviceability Limit deflections The stiffnesses of floors and roofs are given in Annex 2.
