Introduction 2

INTRODUCTION Construction details Introduction Founded in 1980, Euroclad is one of the UK s leading manufacturers of steel and aluminium roofing and cladding systems. Main brands, including Elite Systems, Euroseam and Secret fix, have become increasingly popular with architects and contractors: the core metal profiling activities being complemented by a full fabrications and flashings capability. Synonymous with reliable service and outstanding technical support, Euroclad has strong links with leading manufacturers for specific system elements. To help customers better understand the thermal performance of metal clad buildings Euroclad have prepared Construction Details, showing thermal efficiencies of joint details and plane elements using three-dimensional models. These details help illustrate the overall thermal performance of a roof or wall as well as the specific heat loss through details per linear metre. 3 As part of its commitment to quality, service and the environment Euroclad operate a Quality Management System approved to BS EN ISO 9001: 2000 and an Environmental Management System approved to ISO 14001.

Introduction SPECIFICATION AND INSTALLATION 4 Amendments to Building Regulations Approved Documents L2 (ADL2) came into effect in April 2002 and impose significant new criteria on the construction of metal buildings. The requirement to reduce CO 2 emissions and produce thermally efficient buildings has a significant effect upon the construction of the building envelope. Essentially, U-values have been reduced for both roof and walls, but more significantly, the method of calculation is now much more rigorous. Complete analysis of the plane elements is now mandatory. The software used to model the detrimental affect of any thermal bridges is now quite sophisticated and therefore gives a much more realistic reflection of the actual thermal performance of the total building envelope. Several different programmes are available (both BRE and Euroclad employ TRISCO) but to be compliant, the model must satisfy BS ISO EN 10211-2. This is the required standard for all compliant three-dimensional thermal models. In a more revolutionary step, the new regulations also require the calculation of the heat loss through all the details of the building envelope. The thermal efficiency of the ridge, eave, gable, window, door junction, cills etc. must all be calculated. Their propensity to create condensation is also evaluated as a result. Two new criteria have been recognised. PSI (ψ ) VALUES The new three-dimensional thermal models not only calculate the U-value on the plane elements, they are also able to produce psi and F-factors for all junctions and details. The psi value reflects the additional heat loss through the detail per linear metre, when compared to the plane elements. The Building Regulations require the heat loss through the details to be included in the evaluation of the building s total thermal performance.

Construction details Introduction There is no need to achieve the lowest possible psi values, it suffices that the efficiency of the details are calculated and can demonstrate compliance with IP17/01 (5.1). CALCULATION OF F FACTORS With the introduction of reduced air leakage requirement there was concern surrounding the possibility of condensation forming on the internal surface surrounding a thermal bridge. The propensity to create condensation is a function of the detail s thermal inefficiency and the temperature/humidity of the environment within the building. Humidity class 1 Building type Storage areas 0.30 2 Offices and shops 0.50 3 Dwellings, residential buildings and schools 0.75 4 Dwellings with high occupancy, sports halls, kitchens, canteens and buildings heated with un-flued gas heaters 5 Special buildings e.g. laundry, brewery and swimming pool Internal humidity class and the external minimum temperature factor necessary to prevent condensation. Minimum F-value 0.80 0.80 Software programmes compliant with BS EN ISO 10211-2 allow calculation of each detail s F-factor. The table above illustrates how knowledge of the building s use and its internal humidity can lead to easy identification of any detail s acceptability. The F-factor is simply compared to the minimum allowable for that classification of building. Dramatic changes in F-factors can be achieved by small alterations in the design. The F-value has only to exceed the minimum requirement. AIR PERMEABILITY The Building Regulations require the testing of the building envelope. Buildings with a gross floor area in excess of 500m 2 must be physically tested. The standard required is: 10 m 3 /h/m 2 at 50 Pascals The Building Regulations specify testing of building air permeability and in that respect the area of the floor is allowed into the calculation. The allowable air loss in cubic metres area of roof and walls and floor multiplied by 10. For example, a building square on plan, with a flat roof, 120m per side and 8m high, the figures would be as follows: 120m x 8m = 960m 2 x 4 (sides) = 3840m 2 120m x 120m = 14400 x 2 (roof and floor) = 28800m 2 Total = 32640m2 So the allowable air loss would be: 326400m 3 /h Test results at BRE have proven that a carefully sealed liner on either a built-up system, or a composite panel, will prove a very effective vapour check. For further details please refer to the section on Sealing of liners in the Euroclad Design and installation recommendations brochure. A copy of the Air Pressure report is to be given to the local authority. 5

HRS Services, Sheffield Contact: E Westgate Tel: 0114 2723003 SUMMARY Extensive computer analysis of Euroclad construction details has shown that standard good practice will often achieve compliance. However, all ψ and F-factors must be calculated and checked to ensure compliance. It should be noted that the application of a particular construction detail in a specific building is determined by the requirements of that individual building. Other factors, such as building type, internal environment and general layout may significantly affect detail choice. This, together with consideration of the details from other parts of the structure (perhaps with a different construction) must be taken into account during design, specification and installation, when determining compliance with the Building Regulations. Air permeability of 10 m 3 /h/m 2 at 50 Pascals has been achieved and bettered both in test and actual experience on site. Good detailing, careful choice of materials, close liaison with the manufacturer and specialist contractor and early involvement of all parties in the project design will prove that an L2 compliant building can be achieved very effectively with a metal envelope. Euroclad has a wide range of products including Standing Seam and Secret fix roofing, trapezoidal/ sinusoidal profiles, aluminium fabrications, flashings, powder coating and composite wall panels. Euroclad can offer a full metal building envelope which is truly integrated by design. The following pages illustrate some standard solutions. Many more are available and particular details can be modelled on a project-by-project basis. If you need any help or further clarification please do not hesitate to contact the Euroclad Sales department.

Thermal performance of built-up systems THERMAL PERFORMANCE OF BUILT-UP SYSTEMS EUROCLAD PLANE ELEMENTS The depths shown on the following four pages are the minimum depths of insulation required to meet the U-values shown. Greater depths may be installed to suit commercially available spacer systems and quilt sizes. EUROCLAD FLASHINGS DETAILS EUROCLAD TRISCO MODEL CONVENTIONS All external boundary conditions assumed to be @ 0 C and 25 W/m 2 K (When the CEN-rule is toggled to HE). All Internal boundary conditions assumed to be @ 20 C and 7.7 W/m 2 K (When the CEN-rule is toggled to HI_NORML). 8 The flashings details shown from pages 14 to 40 all give guidance on the F and ψ values and these values are also dependant on the U-values of the plane elements to which they are adjacent. For modeling purposes, all roof elements are assumed to be 0.25 U-value and all wall elements are assumed to be 0.35 U-value. Air cavities, where applicable, are modelled as material blocks using the type EQUIMAT, as explained in sections C.6-C.8 in the Trisco Manual.
