Page 8 - European Technical Approval ETA-05/0022

Validity from 12/05/2005 to 12/05/2010

2 Characteristics of product and methods of verificat ion

2.1 Mechanical resistance and stability (ER1)

The mechanical performance of the building elements was determined according ENV 1995-1-1 : 2003.

The mechanical data corresponds to :

• Solid wood: EN 338 / EN 385

• Particle board: EN 312

• “Staples” : german technical approval Nr Z-9.1-73 and Z-9.1-1976.

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

2.2.1 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.

2.2.2 Resistance to fire

For the external wall, resistance to fire is based on a full scale testing: classification is given according to EN 13501.

External wall : REI 30

For the floor, resistance to fire is given on the bases of a calculation according to Eurcode 1995-1-2 (10.2002).

Floor : R15

No performance determined for the roof.

2.2.3 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.

Page 9 - European Technical Approval ETA-05/0022

Validity from 12/05/2005 to 12/05/2010

2.3 Hygiene, Health and Environment

2.3.1 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.

2.3.2 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.

2.3.3 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

2.4.1 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.

2.4.2 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.

4 Assumptions under which the fitness of the product for the intended use was favourably assessed

4.1 Design

For every house, a set of specific plans and a set of details is available, based on specific design and also including eventual local specification.

The mechanical design is performed case by case.

4.2 Manufacturing

The kit is manufactured by WeberHaus (D-Linx) which has been using a specific manufacturing process summarised here after and identified during inspection of the plant by the Centre Scientifique et Technique du Bâtiment and laid down in the technical documents.

For each building element (wall, floor, roof) the main manufacturing stages are as following :

• Preparation of the timber frame,

• Fixing on one of the boards with vapour barrier,

• Preparation for plumbing and electricity,

• Installation of insulation panels,

• Fixing of the other board or lathing to “close” the element.

At the end of each assembly belt, the elements are loaded on a trailer and covered with a canvas cover and stored until delivery.

4.3 Installation

As for the manufacturing, the erection is ruled by specific process policies.

The installation is generally performed in one day with a team of 4 people :

• Erection of external wall immediately anchored on the foundation and the each other,

• Fixing of internal walls,

• Installation of the floor elements,

• Fixing of jamb wall and gable,

• Installation of purling and collard,

• Fixing of the roofing elements,

• Covering of the roof,

• Filling the joints between elements,

• Application of the screed,

• Internal finishes.

Validity from 12/05/2005 to 12/05/2010

5 Recommendations

5.1 Packaging, transport and storage

The elements are properly prepared to limit deformation and degradation during transportation. They are placed under a canvas cover in the workshops to get sufficient protection before storage.

Transportation is scheduled in a way to complete the erection in one day.

5.2 Maintenance and repair of works

When delivering the house, WeberHaus provides to their clients a maintenance manual taking into account all the aspect of the house.

5.3 Technical assistance

WeberHaus also provides technical assistance.
