SCOPE

This Agrément relates to the Mauer External Wall Insulation (EWI) System (hereinafter the “System”). The System is designed for use as a mechanically fixed,off-site manufactured (OSM), EWI façade cladding system, for installation over the external solid walls of existing buildings. It is effective in reducing the thermaltransmittance (U value) of masonry or stone solid walls (where masonry includes clay and calcium silicate bricks, concrete blocks and natural and reconstitutedstone blocks) and enhancing the aesthetic look of the building. The System can be used on existing domestic and non-domestic buildings up to and including 6storeys in height (18 m).

DESCRIPTION

The System consists of a light gauge steel main frame with insulated spacers supporting a breather membrane, an insulated inner cavity and a secondary lightgauge steel support frame. The light gauge steel support frame both maintains an outer ventilated and drained cavity and acts as the fixing grounds for the outercomposite façade board (CFB) finish.

CHAPTER 2 – TECHNICAL ASSESSMENT

2.1 – POINTS OF ATTENTION FOR THE SPECIFIER

2.1.1 Delivery, storage and site handlingThe System is delivered as a building specific ‘kit of parts’. The steel main frame and support frame is delivered to site either pre-assembled or as singlecomponents, dependant on the project specific design. The glass mineral wool (GMW) insulation is delivered in bales and must not be allowed to get wet.

The pointing mortar and approved sealant should be stored and used under the appropriate temperature conditions. See Section 2.3.2.

2.1.2 Permitted applicationsOnly applications designed according to the specifications as given in this Agrément are allowed under this Agrément, in each case the specifier will have to co-operate closely with the Agrément holder.

All manufactured components of the System are ‘made to measure’ and can only be used on one specific building. Key Mauer (manufactured) components areissued with a master (parent) serial number so that they can be traced through the manufacturing process to each specific building.

2.1.3 Building physicsThe physical behaviour of walls incorporating the System shall be verified as suitable by a competent specialist, who can be either a qualified employee of thespecifier or a qualified consultant. The specialist will check the physical behaviour of the designed external wall construction and if need be advise aboutimprovement to achieve the final specification. It is recommended that the specialist co-operates closely with the Agrément holder.

2.1.4 General Design ConsiderationsAccount should be taken of both System specific and project specific design considerations. System specific considerations shall be addressed by the specifier;project specific considerations shall be addressed by the Approved Installer in the form of the project specific design.

System specific considerationsThis Agrément covers the use of the System in any exposure zone, subject to the following conditions being met (they are particularly important in areas subjectto severe or very severe driving rain): Compliance with the relevant national Building Regulations. Compliance with weathertigtness in accordance with BRE Report 262, the local wind-driven rain index and the site exposure zone using BS 8104.

Note:The ventilated and drained cavity behind the CFBs must not be allowed to become blocked. The ventilation openings at top and bottom shall be suitablyprotected by screens or baffles to prevent the ingress of rain, birds or animals.

Project specific considerationsA building specific site survey is completed and documented by the Approved Installer prior to installation to ensure that the building is suitable to receivetreatment.

This process includes: Substrate wall fixing pull-out resistance tests to BS 5080-2 to determine pull-out values. A 3D laser scan of the existing building is carried out for every project to capture field data to determine exact dimensions, depth of window reveals etc.

The point cloud data is then converted using specialist software, realigned and merged to a 3D model of the building to create scaled CAD elevationdrawings for the project.

Subsequent project specific design considerations include confirmation that: There is no existing rising damp and there are no signs of dampness on the inner face of the solid wall, other than those caused solely by condensation Existing walls are structurally sound Existing walls are watertight

The average yearly wind load action data for the site location is collated and used to calculate the design wind resistance - positive or negative (kN/m2) for agiven steel frame spacing and fixing centre spacing layout design. Wind action loads shall be calculated in accordance with BS EN 1991-1-4. When calculatingwind loads at corners, higher pressure coefficients shall be used, as recommended in the appropriate Standards.

This design process allows the Agrément holder to produce a building specific kit of parts, components and drawings. Detailed technical installation layoutdrawings provided for each installation show the specific set out position required of each frame and component within the System, with reference to highlighteddatum points for accuracy. Each building receives its’ own specific set of design installation details (the Property Information Pack) and materials.

During the project specific design process, account should be taken of Government Accredited Construction Details for Part L – Masonry external wall insulationdetails: Illustrations. Care is needed for design at openings, and the correct level of workmanship and design detailing of joints particularly around window anddoor openings should be in accordance with BS 6093.

2.1.5 EnvironmentalThe GMW insulation has a Generic BRE Green Guide rating A+, and has zero Ozone Depletion Potential and zero Global Warming Potential.


Performance factors in relation to the major points of assessment

2.1.6 Thermal insulationThe requirement for limiting heat loss through the building fabric, including the effect of thermal bridging can be satisfied if the thermal transmittance (U-value) ofthe wall incorporating the System does not exceed the maximum and target U-values in the relevant Elemental Methods given in the national BuildingRegulations.

For the purpose of U-value calculations and to determine if the requirements of the national Building Regulations or other statutory requirements are met, thethermal resistance and U-value of the walls incorporating the System should be calculated according to BS EN ISO 10211 (taking into consideration BS EN ISO6946, BS EN ISO 10456 and BRE Report 443) using the insulation’s declared thermal conductivity (λD).

Where an existing external solid wall is subject to national Building Regulations, for example a material change of use, designers should take account of therelevant guidance relating to technical and economic feasibility and target U-values in the documents supporting those Regulations.

If installed correctly, the GMW insulation will remain dry and in a stable state – ensuring a continuous thermal performance throughout the life of the insulation.

A thermal bridging report, using 3D TRISCO software, in accordance with BS EN ISO 10211 (using design thermal values in accordance with BS EN ISO 6946,BS EN ISO 10456 and BRE Report 443) has shown that the System will deliver a thermal benefit given as a U value of 0.30 W/m2K.

2.1.7 Thermal bridging at junctions and around openingsCare must be taken in the overall design and construction of junctions with other elements and openings to minimise thermal bridges and air infiltration.Guidance on linear thermal transmittance, heat flows and surface temperatures can be found in the documents supporting the national Building Regulations andBS EN ISO 10211, BRE Information Paper IP 1/06, BRE Report 262, BRE Report 497 and PAS 2030 - Building Fabric Measures (BFM).

To avoid cold bridging: The light gauge steel main frame is separated from the substrate wall by a 6 mm minimum thickness approved closed cell rubber insulation thermal break All door/window heads, cills & reveals are insulated using a 6 mm minimum thickness approved closed cell rubber insulation thermal break

2.1.8 Structural loadingThe supporting wall must be able to take the full wind load, as well as any racking load, on its’ own. No contribution from the System may be assumed in thisregard. The project specific design must ensure that: The System attachment to the substrate wall has adequate fixing pull-out capacity for the calculated wind loads Thermal expansion effects of both the steel main frame and support frame and the cladding to be supported are taken into consideration in the design

and detailing.

The design of the steel main and support frames is in accordance with the relevant codes and Standards so as to limit mid-span deflections to L/200 andcantilever deflections to L/150. The System has adequate dynamic wind uplift load (suction) resistance.

2.1.9 Impact resistanceFor hard and soft body impact resistance, the System is categorised as Category I and can therefore be used in all conditions as detailed below: I – a zone readily accessible at ground level to the public and vulnerable to hard body impacts but not subjected to abnormally rough use II – a zone liable to impacts from thrown or kicked objects, but in public locations where the height of the kit will limit the size of the impact; or at lower

levels where access to the building is primarily to those with some incentive to exercise care III – a zone not likely to be damaged by normal impacts caused by people or by thrown or kicked objects IV – a zone out of reach from ground level

2.1.10 Condensation riskExternal walls incorporating the System will adequately limit the risk of interstitial and surface condensation when designed in accordance with BS 5250 andBRE Report 262. A condensation risk analysis shall be completed at project specific design stage. Assuming the installation has taken place on an occupiedbuilding, and when correctly installed, no dampness will be present on the internal wall.

Interstitial condensationExternal walls incorporating the System will adequately limit the risk of interstitial condensation when they are designed and constructed in accordance with BS5250 and BRE Digest 369. The ‘dew’ point is calculated to occur at the breather membrane location – which is designed and specified to release vapour at therate required. Therefore, warm vapour transmitting through the substrate wall, from an internal space, will continue to be ‘pushed’ through the surface of theBreather Membrane – condensating at this point.

Surface condensationExternal walls incorporating the System will adequately limit the risk of surface condensation on internal walls when designed in accordance with BS 5250.

2.1.11 Resistance to precipitation including wind-driven rainDesign of joints should be in accordance with BS 6093. The finishing detail is designed to minimise any water ingress through joints between each CFB.Providing the joints between CFBs are correctly sealed, there should be no ingress into the cavity by wind-driven rain. The System is ‘sealed’ with a W1 ratedbreather membrane, breather tapes, thermal breaks, and pointing mortar and approved sealant.

The System, when properly installed in accordance with this Agrément, will resist rain penetration to the wall substrate and satisfy this Requirement as given ineither the relevant national Building regulations or BRE Report 262. The System can help to protect existing external facing brickwork from severe weatherconditions.

The ventilated and drained cavity between the back of the CFBs and the main breather membrane must be a minimum width of 20 mm. Any water collecting inthe cavity owing to rainwater or condensation will be removed by drainage and ventilation.


A hygrothermal conditioning test and wind-driven rain test on the installed System has successfully been carried out to ETAG 034 and both indicatethe suitability of the System for use at a level of rain exposure classed as very severe i.e. in all wind-driven rain exposure zones in accordance withBS 8104.

2.1.12 Water vapour transmission resistanceThe GMW insulation protected by the breather membrane and ventilation gaps at head and base all aid moisture release from inside the building. Theventilation area at the base of the cladding should be equivalent to 500 mm2/m run.

2.1.13 Behaviour in relation to fireThe System is classified as Euroclass A2-s1, d0 (non-combustible) according to BS EN 13501-1.

2.1.14 DurabilityThe System comprises durable materials and the ventilation openings at top and bottom shall be suitably protected by screens or baffles to prevent the ingressof rain, birds or animals. There is no mould risk to any component in the System.

Providing regular inspection and maintenance is carried out and any defects promptly repaired in accordance with the Agrément holder’s Maintenance andRepair Guide, the installed System should be effective as an EWI System with an ultimate service life expectation in excess of 30 years.

2.1.15 Maintenance and repairAs the insulation is confined behind the membrane and has suitable durability, no maintenance is required. Should it become necessary for any reason, theGMW insulation can be evacuated from behind the membrane.

For advice in respect of routine cleaning and annual maintenance inspections, consult the Agrément holder’s Maintenance and Repair Guide.

Damaged CFBs should be replaced as soon as is practicable as per the Agrément holder’s Maintenance and Repair Guide.
